Circumstances:
On October 4, 1960, at 1740 e.d.t., an Eastern Air Lines Lockheed Electra, N 5533, crashed into Winthrop Bay immediately following takeoff from runway 9 at Logan International Airport, Boston, Massachusetts. Ten of the 72 persons aboard survived the crash. The aircraft was totally destroyed. A few seconds after becoming airborne, the aircraft struck a flock of starlings. A number of these birds were ingested In engines Nos. 1, 2, and 4. Engine No. 1 was shut down and its propeller was feathered. Nos. 2 and 4 experienced a substantial momentary loss of power. This abrupt and intermittent loss and recovery of power resulted in the aircraft yawing to the left and decelerating to the stall speed. As speed decayed during the continued yaw and skidding left turn, the stall speed was reached; the left wing dropped, the nose pitched up, and the aircraft rolled left into a spin and fell almost vertically into the water. An altitude of less than 150 feet precluded recovery. The Board determines that the probable cause of this accident was the unique and critical sequence of the loss and recovery of engine power following bird ingestion, resulting in loss of airspeed and control during takeoff.

Circumstances:
Eastern Air Lines Flight 18 is a scheduled operation serving the carrier's route between New York City and Massena, New York, and its intermediate stops at Albany, Plattsburg, and Malone, New York. On November 14, at 1245, the flight originated on schedule, its flight crew consisting of Captain Joseph W. Harpham, First Officer Robert Casper and Flight Attendant Nancy A. Price. The flight followed routine preparation and was in accordance with an IFR (Instrument Flight Rules) flight plan. The general weather conditions over most of the route were forecast to be good. The flight proceeded through the intermediate stops in a routine manner, with most passengers deplaning at Albany and Flattsburg. Just prior to reaching Malone the instrument flight plan was canceled in good weather conditions. The flight landed at Malone at 1502. Continuing uneventfully, Flight 18 departed Malone at 1510. The gross takeoff weight of the Martin 404 was 35,977 pounds, 8,923 pounds under the maximum allowable. According to the load manifest the load was properly distributed within the center of gravity limitations. The first officer made the takeoff, climbed the aircraft approximately 2,500 feet, and flew it to Massena. Captain Harpham from his left seat, supervised the flight and performed the duties of copilot. At 1516, when about eight miles east of Richards Field, Captain Harpham reported the flight's position, then asked for and received landing information, which included the surface wind as “northeast 5 to 10 knots," and the active runway 4 (150 feet wide and 4,000 feet long). First Officer Casper established a downwind leg at 1,200 feet to execute a rectangular left-hand pattern for landing on runway 4. The flight was viewed briefly by ground observers during the pattern before reaching the final landing approach and it seemed entirely normal. As the aircraft drew closer to the threshold it seemed high and thereafter assumed an abnormally steep descent. As it approached the runway surface the aircraft assumed a flareout attitude, however, the rate of descent continued with little visible abatement. Consequently, N492A contacted the runway surface with great force at which time the right powerplant separated from the aircraft. The aircraft rebounded and again contacted with great force. It then rolled forward and gradually off the runway to the right. Before stopping it crossed a taxiway and the left powerplant fell free, accompanied by a small fire in the engine and the empty nacelle area. As the aircraft stopped Captain Harpham shut off the fuel and electrical services and ordered the loading ramp lowered. The passengers and crew quickly evacuated by this exit without difficulty or reported injury. At 1522, two minutes after the accident, weather conditions were reported as: Ceiling 4,000 feet broken, 10,000 feet, overcast; visibility 3 miles; haze; wind northeast 6 knots.
Probable cause:
The Board determines that the probable cause of this accident was the captain's incorrect technique during the final approach which resulted in an abnormally steep nose-down attitude and high rate of descent, the latter not being sufficiently arrested before touchdown. The following findings were reported:
- The first officer operated the aircraft in the traffic pattern,
- During the turn to the base leg and while on base leg, an overriding was allowed to drift the aircraft closer to the airport,
- From a higher and closer than normal position on final approach, the captain took control of the aircraft and continued the approach,
- The throttles were closed, landing flap was extended, and the aircraft was slowed to 95 knots,
- The aircraft descended in an abnormally steep nose-down attitude and at a high rate of descent,
- The altitude remaining was insufficient for the aircraft in its existing configuration to regain adequate flareout speed,
- The flareout attitude was accomplished; however, the rate of descent continued with little abatement,
- The aircraft contacted the runway with great force causing major structural damage,
- Important limits in the approach technique were not included as part of company pilot training,
- There was no malfunction or failure of the aircraft prior to the runway contact.

Circumstances:
Flight 181 originated at Midway Airport, Chicago, Illinois, for Miami, Florida. Several stops were scheduled including Indianapolis, Indiana, and Louisville, Kentucky, the latter a point of crew change. Departure, scheduled for 0955, was at 1001, with a crew of Captain Clarence G. Chambers, Pilot Harold D. Bingham, and Stewardess Shirley Michael. To Indianapolis the flight was routine, with Captain Chambers flying, and arrival was on schedule. Departure from Indianapolis was on schedule, at 1105, with 31 passengers and 450 gallons of fuel. The aircraft’s gross weight was 41,126 pounds, 3,774 less than the maximum takeoff allowable of 44,900, and its center of gravity was located within prescribed limits. Captain Chambers instructed Pilot Bingham to do the flying and, accordingly, Bingham, seated on the right, made the takeoff and flew this segment of the flight. The aircraft proceeded along V-53 airway at 5,000 feet altitude on a VFR flight plan in clear weather. At 1133 the flight advised Standiford (Louisville) tower that it was over New Albany, Indiana, eight miles to the north-northwest, and requested clearance to the airport. At 1134 the flight asked landing information of its company radio station and was given the Louisville pressure altitude as 340 feet and the Louisville altimeter setting as 30.10 inches. A minute later the flight advised the tower that it was over the city and received clearance to land on runway 11. Wind conditions were given as southeast five to eight knots, variable both sides. Ceiling and visibility were unlimited. The “Fasten Seat Belt” sign had been put on. Pilot Bingham descended from 5,000 feet to 2,000 feet and then reduced both rate of descent and power. An airspeed of 165 knots was established, the landing gear was lowered, and the flaps were placed in takeoff position. Bingham then started a turn for final approach, and the flaps were placed in approach position. Captain Chambers saw that the aircraft was too high and reduced power still further; Bingham lowered the flaps to full down. The pre-landing checklist had been accomplished. At this point (the altitude was then 1,000 to 1,500 feet higher than the runway) the captain took over control. He nosed down sharply, holding as closely as possible to an airspeed of 100 knots. The landing gear remained down, flaps remained fully down, and throttles were pulled fully back. Neither pilot read the rate-of-climb (descent) indicator during the approach. When approximately over the threshold of the runway and while about 100 feet above it, the captain pulled back on the yoke to flare out. No power was used. The aircraft’s attitude was observed to change from nose-down to nose-up but its rate of descent did not seem to lessen markedly. The aircraft struck the runway on its main landing gear, the left wing separated inboard of the left engine nacelle, and the remainder of the aircraft half rolled to an inverted position. It slid along in that attitude, turning and coming to rest headed nearly opposite its direction at touchdown. Two minutes later, by estimate, all occupants were out of their inverted seats, in which they were belted, and away from the wreckage which had developed a small fire. This was confined by a passenger using a hand extinguisher until emergency apparatus, which had been alerted by the tower, arrived quickly and took the necessary steps to prevent further fire.
Probable cause:
The Board determines that the probable cause of this accident was the captain’s faulty landing approach technique, resulting in an excessively high rate of sink at the instant of touchdown imposing load beyond the design strength of the wing stricture. The following findings were reported:
- An approach was started from a paint too close and too high in relation to the approach end of the runway,
- The speed and configuration of the aircraft in conjunction with the retarded throttle during this approach resulted in an inordinately high rate of descent,
- This high descent rate was not sufficiently checked during the attempted flareout,
- Touchdown imposed loads beyond the design strength of the wing structure, which failed.

Circumstances:
Eastern Air Lines Flight 156 of February 17 was a scheduled operation between Evansville, Indiana, and Chicago, Illinois, with intermediate stops at Owensboro and Louisville, Kentucky. It utilized the aircraft and flight crew of Trip 157 from Chicago, which terminated at Evansville. The crew consisted of Captain Charles R. Hard, Pilot Raymond F. Rozman, and Flight Attendant Robert T. Schroeter. The Chicago to Evansville flight arrived at 1422, 43 minutes late because of traffic and ground delays. It was reported routine in all other respects. During the short ground time at Evansville Captain Bard reviewed the weather forecasts for the flight Evansville to Chicago, and received the latest weather observation reports for Owensboro, the first stop. These indicated the flight to Owensboro would be in accordance with Instrument Flight Rules and that an instrument approach to the airport there would be necessary. Accordingly, an IFR flight plan was filed and an instrument clearance was given the crew before departure. Clearance was direct to Owensboro at 2,000 feet. Flight 156 departed at 1441. Gross takeoff weight was 41,471 pounds, which was less than the maximum allowable, 43,306 pounds. The load was properly distributed with respect to the center of gravity limits of the aircraft. The crew reported its position en mute to ATC (Air Traffic Control) according to its clearance and thereafter at 1447 called the company radio located on the Owensboro Airport. Routine information exchanged between flight and ground personnel included giving the flight the latest weather and altimeter information. There being no control tower at Owensboro, the company there advised the flight that surface wind favored landing on runway 05. A few minutes later N445A was observed to descend below the clouds just north of the airport, flying on a southerly heading toward the field. It was observed to level out and turn right onto a downwind leg for runway 05. In the limited visibility, reported as one mile in rain and fog, the aircraft disappeared from view near the southwest boundary of the airport while still, on its downwind leg. Shortly thereafter it came back into view, proceeding toward the landing runway. It suddenly struck the ground, right wing down, rolled to an inverted position, and slid to a stop beside runway 05. The aircraft lost its both wings and was partially destroyed. All 23 occupants were evacuated.
Probable cause:
The Board determines that the probable cause of this accident was an improperly executed final approach, resulting in a stall, during a steep left turn at an altitude too low to permit recovery. The following findings were reported:
- Weather conditions reported were above the minimums for the flight to execute an ADF approach, circle, and land,
- Weather conditions experienced by the flight were equal to or better than those reported,
- The flight established visual contact with the ground at a position which was normal following the completion of the specified instrument approach procedure,
- A circling approach was begun to land on runway 05,
- The position on the downwind leg from which a left turn was begun to align with runway 5 resulted in little or no straight-in portion of the approach and an abnormally steep turn,
- During the latter phase of the approach while at low altitude the aircraft rolled from a steep left bank to the right in a continuous motion,
- The aircraft struck the ground short of and to the right of the runway of intended landing in an uncontrolled attitude,
- There was no evidence of malfunction or failure of the aircraft, its engines, or propellers,
- Thunderstorm turbulence, wind shift, and lightning were not factors in the accident.

Circumstances:
Flight 642 originated at Miami, Florida, with its destination Boston, Massachusetts; Jacksonville, Florida, was included as an intermediate stop. The captain was briefed by the company forecaster on the en route weather and terminal forecasts, and following the briefing the flight was dispatched to Jacksonville on an IFR (Instrument Flight Rules) flight plan. This plan specified a flight to be made via Victor Airway 3 at a Cruising altitude of 11,000 feet. The crew consisted of Captain Thomas Francis McBrien, Pilot John Jay Rinyu, Flight Engineer Charles Calvin Devine and Flight Attendants Emma Elizabeth Williams and Clara Dorothea Rioseco. There were 12 passengers on board. Flight 642 was scheduled to depart Miami International Airport at 2340, December 20, but because of the late arrival of an inbound flight using the aircraft involved departure was not made until 0212, December 21. According to company records the gross weight of the aircraft at the time of departure was 85,944 pounds, which was under the allowable takeoff gross weight of 107,000 pounds; the load was properly distributed. Routine en route radio reports were made and at 0315 the flight reported over Daytona Beach at 11,000 feet, estimating Jacksonville at 0336. This report was made to the company's Jacksonville station and at this time the flight was given the Jacksonville 0248 U. S. Weather Bureau special report: "Thin obscuration, 2 miles visibility; ground fog; wind north-northwest 6 miles per hour; 30 percent of sky obscured." After this message was acknowledged, the flight was given the following clearance: "Jacksonville air route traffic control clears Eastern Air Lines Flight 62 to Jacksonville middle marker ILS, cross middle marker IlS at 2.500 feet, maintain 2,500 feet until further advised. Contact Jacksonville approach control when over Sunbeam Intersection." The clearance was acknowledged. Flight 642 contacted Jacksonville approach control when over Sunbeam Intersection (16 miles SSE of Imeson Airport) at 0331 and was cleared for an ILS approach to runway 5. At the same time the Jacksonville weather was given as: "Partial obscurement; visibility one-half rule; altimeter 30.18." Immediately following this transmittal another message was given the flight, "Coming out with indefinite 300 obscurement now one-half with fog." (Eastern Air Lines' Constellation minimums for ILS approaches at Jacksonville, day or might are ceiling 200 feet, visibility one-half mile). After acknowledging this weather information, Flight 642 reported leaving. Sunbeam at 2,500 feet. Following a later query from the flight, approach control advised that there was no other known traffic in the area, and requested the flight to report when over the outer marker inbound. Flight 642 reported over the outer marker inbound and was cleared to land. Shortly thereafter the tower controller observed a large flash in the vicinity of the ILS middle marker. Calls to Flight 642 were not acknowledged and an emergency was declared by the controller. It was subsequently learned that N112A had crashed approximately six-tenths of a mile southwest of the threshold of runway 5. Investigation disclosed the main portion of the wreckage to be 212 feet northwest of the ILS middle marker and 3,486 feet southwest of the threshold of runway 5. The time of the accident was established as 0343LT. First impact of the aircraft was with the top of a small pine tree approximately 200 feet below the ILS glide path, 260 feet to the left of the extended centerline of the runway, 4,000 feet from the threshold of runway 5, and 420 feet southwest of the middle marker. This was followed by striking a 50-foot oak tree, the upper 20 feet of which was sheared off. The aircraft settled toward the ground, striking other large trees which disintegrated both wings and a portion of the empennage. Ground contact was on a heading approximately 55 degrees magnetic. The distance from the first tree struck to the farthest piece of wreckage was 801 feet. Explosion and fire occurred immediately upon impact.
Probable cause:
The Board determines that the probable cause of this accident was that during the final portion of an IIS approach the pilot, for reasons not determinable, either permitted or caused the aircraft to deviate to the left of course and descend below the glide path to an altitude too low to clear ground obstructions. The following findings were reported:
- No evidence of failure of the airframe, power plants, controls, or other components was found,
- The weather at the airport was marginal with local fog and restricted visibility; however at last report the weather vas above the carrier's minimums,
- Ground navigational facilities in the Jacksonville area, including the ILS system, functioned normally during the approach,
- There was no operating difficulty reported by the crew,
- There were no other known aircraft in the immediate area,
- While on final approach, the aircraft descended considerably below the glide path and below the minimum altitude before reaching the middle marker,
- Trees were struck six-tenths of a mile from the runway threshold approximately 200 feet below the glide path and 260 feet to the left of the extended centerline of the runway.

Circumstances:
The crew of Flight 627 consisted of Captain C. C. Foxworth Captain E. M. Engle, (first officer), Flight Engineer L. P. Devries, Flight Attendant A. J. Folli, and Flight Attendant A. L., Krause. On departure from the ramp, the gross weight of the aircraft was 95,838 pounds; allowable gross takeoff weight was 105,530 pounds. The load was distributed so that the center of gravity of the aircraft was within the approved limits. Flight 627 initially taxied out at 2345, bar 18, for takeoff from Runway 7R. This flight and a preceding flight returned to the ramp because fog drifted in and reduced visibility below the approved minimum of one-fourth mile while they were awaiting clearance for takeoff. 2 Neither flight was issued off clearance, although according to Captain Foxworth, they held at Runway 7R about 15 minutes. The captains of flights reported that when they arrived at Runway 7R the existing visibility was well over the required one-quarter mile, as they could ace beyond the far end of the 8,200-foot runway, and so advised the control tower. About 15 minutes after returning to the ramp, Captain Foxworth was advised by Eastern Operations that visibility had improved, and the flight again taxied out, following another Eastern aircraft, Flight 623W. While they were taxing, the tower suggested that takeoff be made on Runway 22L and advised that visibility to the south-southeast, from tower location, was three miles. Since both flights had taxied beyond this runway at the time this information was conveyed to them, they turned around and Captain Foxworth, now in the lead, took position for takeoff near the end of Runway 22L. The tower advised Flight 627 that the weather was now being reported as thin obscuration, one and one-half miles visibility, fog, and smoke. 4 Captain Foxworth opened the left side "clear-view" window for maximum visibility. The runway lights were turned to full intensity, and the landing lights of the aircraft were on. Captain Foxworth observed that visibility appeared to be at least one-fourth mile, and stare could be seen. He could see the runway border lights and down the runway centerline for some distance. He said that he was unable to see past the intersection. The engines were run up, cockpit checks completed, and airways clearance via Long Beach, Sully, and Woolf intersections was received. Takeoff clearance was issued at 0055, October 19. Captain Foxworth, flying from the left, made the takeoff using the runway border lights and centerline as visual reference guides. The first officer also maintained visual reference except when he briefly directed his attention to retraction of the landing gear. In the takeoff run the captain noticed that visibility was variable due to fog and seemed to get progressively worse, but later stated that he had "expected to come out on top almost any second" after becoming airborne; he did not go on instruments. Takeoff seemed normal. Shortly after calling for retraction of the gear. Captain Foxworth observed that air speed was approaching 110 knots. He said that he lost all ground references at about the intersection of Runways 19L, 25L, and 22L, at or shortly after becoming airborne. A few seconds later he heard the first officer shout a warning and they struck the ground while at takeoff power. A second or two after the first officer moved the landing gear handle to retract position and again directed his attention outside, he saw they were quite low, grabbed for the control wheel to pull the nose up, and simultaneously shouted a warning. He did not recall whether he got his hands on the wheel before impact. The aircraft struck the ground to the left of Runway 22L at Taxiway F. It bounced, and following the second impact skidded to a stop in an undeveloped part of the airport south of Taxiway G. An intense fire immediately developed in the left wing at No. 2 engine position. The pilots, flight engineer, and one passenger left through the crew door, located just to the rear of the cockpit on the right side; all other occupants exited in orderly fashion through the main cabin door at the left rear side of the aircraft.
Probable cause:
The Board determines that the probable cause of this accident was the captain's loss of visual reference and orientation when he encountered drifting fog shortly after becoming airborne on takeoff, and the resultant inadvertent assumption of a descending flight path. The following findings were reported:
- The general visibility figure given to the flight at about the tine clearance was issued for takeoff was ceiling unlimited, visibility one and one-half miles,
- From his position at the end of the runway, the captain estimated visibility to be about one-fourth mile, which was within the CAA-approved limits,
- A visual takeoff was made by the captain with the first officer also maintaining visual reference to the ground,
- Near the main intersection, slightly more than one-fourth mile from start of the takeoff run, the aircraft encountered fog which greatly reduced visibility,
- Although the aircraft became airborne, it did not penetrate the top of the fog
- The first officer saw the ground an instant before impact, but the aircraft struck before corrective action could be taken,
- There was no evidence of failure or malfunction of the aircraft, engines, or propellers before impact.
Final Report:
