Lockheed L-188 Electra

Flight 708 was a scheduled domestic flight from Jakarta to Manado, with intermediate stops at Surabaya and Makassar. It departed Djakarta at 0030 hours GMT on 15 February and proceeded on an IFR flight plan to Surabaya. While en route to Surabaya No. 4 engine would not synchronize. The flight landed at 0200 hours at Surabaya where an oil leak on No. 1 propeller was found. After rectifying these faults the flight departed from Surabaya at 0300 hours. On approaching Makassar bad weather was reported and after two attempts to land, the pilot-in-command elected to divert to another aerodrome. Two aerodromes were available - Denpasar, the first alternate and Surabaya. Although Surabaya was at a greater distance, the pilot-in-command decided for various reasons to return to Surabaya-Juanda and remain overnight. An oil leak on No. 1 propeller was again observed and noted for rectification. The flight departed the next morning at 0010 hours for Makassar where it landed without incident. After approximately a one hour stop at Makassar the flight proceeded to Menado with an estimated time of arrival there of 0512 hours GMT. On approaching Menado the pilot-in-command requested the weather conditions and was given a cloud base of 900 ft and a visibility of 2 km. At an altitude of 1 500 ft the town of Menado and the beach were visible and the aircraft made a 360° turn over the bay of Menado: the aircraft then descended to 900 ft and intercepted the beach on a heading of 120' intending to make an approach to runway 18. The pilot-in-command sighted the runway to his right, continued the approach through a gap between two hills, and called for the undercarriage to be lowered and completion of final checks. He instructed the flight engineer to stand by for an overshoot at which time the approach was being continued with the flaps in the landing position. The aircraft banked 15°-20° to the right, and the co-pilot monitored and called the airspeed. After passing a hill 200 ft above the runway elevation and some 2 720 ft before the runway threshold the pilot-in-command realized he was too high, also the aircraft was still to the left of the centre line and banked to the right. The nose of the aircraft was lowered and after intercepting the glide path at an indicated airspeed of 130 kt the control column was moved rearwards to a normal descent position. With the airspeed rapidly decreasing below the target threshold speed of 125 kt, and whilst still banked to the right, the aircraft landed heavily 3 ft short of the runway manoeuvring area and some 156 ft short of the runway threshold. The undercarriage collapsed and the aircraft skidded, caught fire and came to rest on the runway 1 442 ft after the threshold on a heading of 225°. 22 passengers were killed.

The aircraft departed Monterey Airport, California, on a charter flight to Columbus, Georgia, with an intermediate stop at Ardmore Municipal Airport, Oklahoma, carrying 93 US soldiers and a crew of five on behalf of the Military Air Command. Following an uneventful flight from Monterey, the crew started the descent to Ardmore Municipal Airport by night and marginal weather conditions. An ADF instrument approach to runway 08 was abandoned and the crew decided to follow a visual approach to runway 30. While descending to runway 30 in poor visibility, the captain (also PIC) suffered a heart attack. The aircraft commenced an uncontrolled descent slightly banked to the right until it struck the ground and disintegrated about 1,5 mile short of runway 30. All five crew members and 75 passengers were killed while 18 others were seriously injured. Few hours later, three of the survivors died from their injuries.

The crew was completing a local training mission at Whenuapai Airport. Following several uneventful manoeuvres, the crew completed a new approach for landing when, on short final, the airplane sank and stuck the runway surface at a speed of 140 knots. On impact, the left main gear was sheared off and the airplane went out of control and veered off runway to the left. While contacting soft ground, the left wing was torn off and the aircraft came to rest in flames. All six occupants were evacuated safely while the aircraft was destroyed.

On August 6, 1962, at 1731 e.s.t., Flight 414, an American Airlines, Inc., Lockhead Electra, N 6102A, crashed during a landing on runway 4L at McGhee-Tyson Airport, Knoxville, Tennessee. Sixty-seven passengers and five crew members were on board the aircraft. All escaped injury except one passenger who suffered a minor injury. The aircraft was substantially damaged. During the landing made by the captain in an area of thunderstorm activity and heavy rain showers, the aircraft skidded to the right off the runway. It struck a newly constructed taxiway the surface of which was approximately 17 inches above ground level, causing failure of the right main landing gear. The right wing became separated front the aircraft. The remainder of the aircraft continued to deviate to the right off the side of the runway for a short distance and came to rest 3,010 feet from the approach end of the runway on a heading of 200 degrees magnetic.

At approximately 0855 1, the flight was cleared for takeoff on runway 14R. At this time the aircraft was taxing on a westerly heading in the runup area adjacent to runway 14R. Flight 706 acknowledged the clearance, while continuing toward the runway, and made a running takeoff No witnesses were found who observed the actual lift-off. N137US was observed after lift-off, 3,000 to 4,000 feet down the runway at an estimated altitude of 50 to 75 feet and in a normal climb attitude. At the 8,000-foot marker the altitude of the aircraft was estimated to have been approximately 100 feet, which is a slightly lower altitude than Electra aircraft normally attain at this point during takeoff. Five witnesses noted a change in engine sound during this portion of the flight. Between the 8,000 and the 9,000 foot runway marker the aircraft was observed to commence an apparently coordinated right turn with a slowly increasing rate of bank. When the bank angle was 30 to 45 degrees, the crew made a short, garbled transmission. Immediately thereafter, at a bank angle of 50 to 60 degrees, the aircraft began to lose altitude. The minimum altitude attained in the entire turn was 200 to 300 feet. The right wing near the No. 4 engine struck powerlines adjacent to the Chicago Northwestern Railroad tracks, severing the lines at an angle of about 70 degrees from the horizontal, and causing a bright bluish flash. The aircraft then continued in a direction of about 271 degrees magnetic and, when in a bank of about 85 degrees and a nose-down attitude of about 10 degrees, the right wing of the aircraft struck the railroad embankment. Continuing to roll about its longitudinal axis, the aircraft cartwheeled, the nose crashing into the ground 380 feet beyond the point of first Impact, and landed right side up It then slid tall first another 820 feet. The aircraft disintegrated throughout its path, and wreckage was strewn over an area 200 feet wide and 1,200 feet long. Evidence of ground fire was found at various points along this path. Impact occurred on airport property about 3,800 feet abeam and to the right of the end of runway 14R, about 500 feet north of Irving Park Road. After passing beyond the railroad embankment the aircraft was lost to view by most of the eye witnesses because of trees and other obstructions; immediately thereafter a large mushroom of orange-red flame accompanied by heavy black smoke was seen. Time of impact was established as 0857. The aircraft was demolished by impact and fire. All occupants were fatally injured.

The approach to Cairo-Intl Airport was completed by night. On final, the four engine aircraft struck a hill and crashed 4 km short of runway 34 threshold. Three crew members and 17 passengers were killed while 16 other occupants were injured. The aircraft was destroyed. Following a crew error, the aircraft was below the glide.

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.

The Electra scheduled as Flight 361 departed Boston at 0716LT with its destination St Louis, Missouri, and with a planned intermediate stop at LaGuardia Airport. About ten minutes prior to departure a crew change was made when a check pilot boarded the aircraft to flight-check the flight engineer. This check pilot, by mutual agreement with the crew and in accordance with existing company policy, took over the left or pilot-in-command seat with the previously assigned captain moving to the jump seat. The trip was routine until final approach at LaGuardia. On final approach, the airplane aircraft was too low and struck a dyke with its main landing gear and crash landed. Approximately half of the 76 persons on board suffered minor injuries or shock; no one was killed. The aircraft was severely damaged by impact forces and fire.

The four engine aircraft departed Chicago-Midway at 1438LT bound for Miami, carrying 57 passengers and a crew of six. While cruising at an altitude of 18,000 feet over the south of Indiana State, the aircraft entered a dive and crashed in a huge explosion in a snow covered field located east of Tell City. Some debris were also found in a wooded area. The aircraft disintegrated on impact and all 63 occupants were killed. The crew was unable to send any distress call prior to the accident.

Flight 542 departed the ramp at Houston at 2237LT, 22 minutes behind schedule with a total of 34 persons including a crew of six consisting of Captain Wilson Elza Stone, First Officer Dan Hollowell, Second Officer Roland Longhill, and Stewardesses Alvilyn Harrison, Betty Rusch and Leona Winkler, none of whom survived. The delayed departure was due to a mechanical discrepancy involving No. 3 generator. This generator was inoperative on arrival of N9705C at Houston. Prior to departure from Houston the Nos. 3 and 4 voltage regulators were interchanged. Actual gross weight upon departure was calculated at 83,252 pounds, including 17,000 pounds of fuel, and was 16,548 pounds less than the authorized gross weight of 99,800 pounds. The estimated time en route to Dallas was 41 minutes. The flight was given an instrument-flight-rules clearance which was to the Leona omni, via Victor Airway 13 west to the Gulf Coast intersection, direct to Leona, to maintain 2,300 feet altitude to Gulf Coast, then to climb to and maintain 9,000. At approximately 2240 the flight was cleared for takeoff and at 2242 it reported ready for takeoff and was airborne at 2244. After takeoff Houston departure control advised that it had the flight in radar contact and requested it to report when established outbound on the 345-degree radial of the Houston omni. Flight 542 complied and subsequently was cleared to 9,000 feet and advised to contact San Antonio Center on 121.1 mcs. upon passing the Gulf Coast intersection. Flight 542 reported to company radio at 2251 as blocking out of Houston at 37, taking off at 42, to cruise at 15,000 feet when so cleared, estimating Dallas at 2325, and that the Center had this information. At approximately 2252 Flight 542 reported to San Antonio Center as being over Gulf Coast intersection at 9,000 feet. The flight was then issued its destination clearance to the Dallas Airport via direct to Leona, direct to Trinidad, direct to Forney, direct to Dallas, to maintain 15,000 feet. The flight was cleared to climb to its cruising altitude. The next transmission from Flight 542 was to the San Antonio, Center, giving the time over Leona as 05 at 15,000. San Antonio Center acknowledged, and requested Flight 542 to change over and monitor the Fort Worth frequency of 120.8 mcs. at this time. The flight acknowledged. Shortly thereafter Flight 542 contacted company radio with a message for maintenance, advising that the generators were then OK out that there had been insufficient time for maintenance to insulate the terminal strip on No. 3 propeller at Houston and it would like to have it done in Dallas. At this time the flight also said it would give the communication center a Dallas estimate of 25. This was then followed by one other item for maintenance, which was that No. 3 sump pump was inoperative. This was the final transmission from the flight and was logged as completed at 2307. Structural failure of the aircraft occurred at approximately 2309 on course to the next fix, Trinidad intersection. The radial from Leona omni to Trinidad intersection is 344 degrees. The main wreckage was located 19.7 miles 2 north of Leona omni, 3.19 miles east-southeast of Buffalo, Texas. The time, 2309, correlates closely with the information obtained from witnesses to the accident as well as the time indicated on impact-stopped watches recovered at the scene. The aircraft was destroyed upon impact and all 34 occupants were killed.
