Circumstances:
Christened 'Clipper Fearless', the airplane departed San Salvador-Ilopango Airport with a delay of five hours due to loading issues. While cruising by night on a cargo flight to Miami, the crew failed to realize his altitude was insufficient and that he was not following the assigned route when the airplane struck trees and crashed in a wooded area located near Mercedes. The aircraft was destroyed and all three crew members were killed.
Probable cause:
The airplane was off course by 37 km at the time of the accident. Investigations were unable to determine the exact cause of this deviation.

While completing the approach check-list, after the gear were extended, three greens lights appears on the panel. When power was reduced prior to touchdown, the gear unsafe warning horn sounded and a red gear unsafe warning light illuminated. The captain first called for a go-around but noticed that the airspeed was too low. The gear was retracted quickly and a belly landing was carried out. While all 59 occupants were evacuated safely, the aircraft was considered as damaged beyond repair.

Circumstances:
Immediately after applying takeoff power, the crew of the DC-6 heard a loud noise and the takeoff was abandoned. A visual check before the plane stopped revealed that the no. 4 engine had separated from the wing. A fire erupted and spread after evacuation, destroying the aircraft. It appeared that the no. 4 propeller had failed and that the unbalanced loads on the engine mounts caused separation of the entire engine. All crew and passengers survived but six dogs the cargo hold died in the accident.
Probable cause:
The accident was caused by fatigue failure of No.1 blade of No.4 propeller. Laboratory findings showed that the failure was caused by previous blade bending resulting in the disruption of the compressive stresses in the shot peened area of the propeller blade.

Circumstances:
The aircraft was on a scheduled flight from San Francisco, California to Singapore with numerous intermediate stops including Manila, The Philippines. It carried a crew of 8 and 49 passengers including one infant. At 21 23 hours (1 June) GMT the aircraft landed on Runway 06 at Manila. During the landing roll, the main landing gears of the aircraft collapsed. The aircraft skidded and swerved to the right until it finally settled on the right shoulder of the runway approximately 2 850 ft from the west end and 27 ft from the edge of the runway. One of the blades of No. 3 propeller flew off and penetrated the cabin area causing the death of one passenger and seriously injuring another. The aircraft was seriously damaged.
Probable cause:
The hard landing of the aircraft caused the failure or collapse of the right main gear 'V' strut support. Contributing factors were the heavy rains and gusty wind.

Circumstances:
Clipper 944, 1 a regularly scheduled around-the-world flight, originated at San Francisco with its first stop scheduled at Honolulu. It departed San Francisco at 1951 2 on November 8 estimating arrival at Honolulu at 0550, November 9. There were 36 passengers and a crew consisting of Captain Gordon H. Brown, First Officer William P. Wygant, Second Officer William H. Fortenberry, Flight Engineer Albert F. Pinataro, Purser Oliver E. Crosthwaite, Stewardesses Yvonne L. Alexander and Marie L. McGrath, and Flight Service Supervisor John E. King. The flight plan specified a cruising altitude of 10,000 feet and an airspeed of 226 knots. Gross weight at departure was 147,000 pounds, the maximum allowable, and the weight included fuel for approximately 13 hours. Good weather was forecast for the duration of the flight. All required position reports were made and Clipper 944 reported to Ocean Station vessel "November" at 0030; its position was fixed by radar as 10 miles east of the vessel. The last position report, at 0104, was routine with no indication of anything unusual. The next scheduled position report, due at 0204, was not received and 30 minutes thereafter the flight was designated unreported. Five days later, nine bodies and some debris were find about 147 miles northeast of the estimated point of impact. There were no survivors among the 44 occupants.
Probable cause:
The Board has insufficient tangible evidence at this time to determine the cause of the accident. Further research and investigation is in process concerning the significance of evidence of carbon monoxide in body tissue of the aircraft occupants. The following findings were reported:
- The gross weight of the aircraft at the time of takeoff was 147.000 pounds, the maximum allowable,
- Progress of the flight and position reports were normal and routine for wore than half of the planned flight distance,
- Shortly after the last routine report an emergency of undetermined nature occurred,
- This was followed by a descent from 10.000 feet,
- No emergency message was received from the aircraft,
- Some preparation for ditching was accomplished,¨
- The aircraft broke up on impact,
- A surface fire then occurred,
- Weather was not a factor,
- Exposure of the crew to carbon monoxide was indicated but incapacitation could not be definitely established,
- No evidence of foul play or sabotage was found,
- Irregularities of maintenance practices and/or procedures disclosed during the investigation could not be linked to the accident.

Circumstances:
Trip 6 of October 13 was a regularly scheduled “around-the-world” flight eastbound from Philadelphia, Pennsylvania. to San Francisco, California. with en route stops in Europe, Asia. and various Pacific Islands. All prior segments had been routine and the flight departed Honolulu on the last leg of the -trip on October 15. It was cleared to San Francisco Airport via Green Airway 9, then track to position 30 degrees N. 140 degrees W. at 13,000 feet. the 21,000 feet to San Francisco. There were 24 passengers aboard., including 3 infants, and a crew consisting of Richard N. Ogg, Captain; George L. Haaker. First Officer; Frank Garcia. Jr., Flight Engineer; Richard L. Brown, Navigator; Patricia Reynolds, Purser Mary Ellen Daniel and Katherine S. Araki, Stewardesses. The 8-hour, 54-minute flight was planned IFR and the aircraft carried sufficient fuel for 12 hours. 18 minutes. The gross takeoff weight of the aircraft was 138,903 pounds (maximum allowable 144,000) and the center of gravity was located within limits. N 90943 departed Honolulu at 2026. The climb to initial altitude was normal and the flight proceeded in a routine manner. At OLO2, the approximate midpoint of the flight, a request for VFR climb to its secondary altitude of 21,000 feet was approved by ATC. After reaching 21,000 feet and simultaneously with the reduction of power, the No. 1 engine oversped. Airspeed was immediately reduced by the use of flaps and reduction of power. Attempts were also made to feather the No. 1 propeller. It was impossible to control the engine or to feather the propeller and the captain decided to freeze the engine by cutting off the oil supply. Shortly after this was done there was a momentary decrease in the r. p. m., followed by a heavy thud. The propeller continued to windmill. At this time airspeed had slowed to 150 knots and the aircraft was losing altitude at a rate of approximately 1.000 feet per minute. The captain contacted the U. S. Coast Guard weather station “November” at 0122., alerted it to a possible ditching. and asked assistance. He also alerted the pas angers to the emergency and told them to prepare for a possible water landing. The flight course was altered to "home in” on station “November” and climb power applied to engines Nos. 2, 3, and 4 to cheek the rate of descent. At this time it was noticed that No. 4 engine was only developing partial power at full throttle. At 0125 the flight notified “November” that ditching was imminent and received a ditching heading from the cutter. During the descent the crew found they could maintain altitude at an airspeed of 135 knots with rated power on engines Nos. 2 and 3 and the partial power on No. 4. About 0137 the flight overheated the cutter. Prior to overheating the cutter the maximum range with the fuel remaining had been computed and it was determined to be insufficient either to complete the flight to San Francisco or return to Honolulu. Mortar flares had been fired by the cutter and electric water lights laid to illuminate a ditching track for the aircraft. However, it was decided to postpone the ditching until daylight, if possible. meanwhile remaining close to the cutter. About 0245 the No. 4 engine backfired and power dropped off. Its propeller was feathered normally. The flight was still able to maintain altitude and continued to orbit “November” to burn the fuel aboard down to a minimum while awaiting daylight. At 0540 Captain Ogg notified the U. S. S. Pontchartrain he was preparing to ditch the aircraft. A foam path was laid along the ditching heading of 3150 by the cutter and the aircraft was ditched at 0615. Passengers and crew safely evacuated the aircraft, boarded liferafts, and were completely clear of the aircraft at 0632. The aircraft sank at 0635 at position 30 degrees 01.5’ N. 140 degrees 09’ W.
Probable cause:
The Board determines that the probable cause of this accident was an initial mechanical failure which precluded feathering the No. 1 propeller and a subsequent mechanical failure which resulted in a complete loss of power from the No. 4 engine. the effects of which necessitated a ditching. The following findings were reported:
- The flight was normal until the control of the No. 1 propeller was lost and the engine oversped,
- It was impossible to control the engine speed or to feather the propeller,
- The engine was frozen, however. the propeller became decoupled from the engine and continued to windmill,
- There was a partial power loss on engine No. 4; it subsequently failed completely and the propeller was feathered,
- Airspeed was restricted to 145 knots to prevent the windmilling Propeller from overspeeding,
- Range of the aircraft was so reduced that it was impossible to reach land,
- The passengers were thoroughly instructed in correct emergency procedures and the aircraft was ditched under control with no fatalities,
- Evacuation of the aircraft was well planned and orderly.

Circumstances:
Trip 845/26, a scheduled flight from Seattle-Tacoma, Washington, to Sydney, Australia, departed Seattle-Tacoma Airport at 0815LT for Portland, Oregon, the first intermediate stop. There were 13 passengers and a crew of 8 consisting of Captain H. S. Joslyn, First Officer A. G. Kendrick, a Navigator N. F. Kerwick, Flight Engineer D. R. Fowler, Assistant Flight Engineer S. Bachman, Purser Natalie B. Parker, Stewardess Elizabeth M. Thompson, and Steward J. D. Peppin. The flight to Portland was normal in all respects with arrival at 0910. There the aircraft was serviced and two additional passengers boarded. Only inspections and service were accomplished. The flight left the ramp at 1010 and took off for Honolulu, Territory of Hawaii, at 1021 on an IFR clearance. Weather conditions at time of takeoff were VFR. There were 15 passengers and the saw crew of 8. Takeoff gross weight was 139,494 (maximum allowable was 145,800 pounds) and the center of gravity was located within limits. The flight plan was via Newberg and Newport, Oregon, and thence to Honolulu to Cruise at 10,000 feet. Estimated flight time was 11 hours and 3 minutes. The flight reported over Newberg at 1031 at 7,000 feet climbing., reached 10,000 feet at approximately 1039, and reported over Newport at 1048 at cruising altitude. The aircraft was then headed to make good the initial track or 221 degrees . Forty-two minutes after takeoff, severe vibration occurred while cruising era at 10,000 feet under VIM conditions. This lasted for five to eight seconds following which No. 3 engine and propeller tore free and fell from the aircraft. The captain immediately disconnected the autopilot. Severe buffeting ensued, the nose want down and the aircraft swung to the right sharply. At this point, the emergency "Mayday" signal was broadcast on both VHF and HF. Direct return to Portland was authorized by Seattle Air Route Traffic Control. The captain, in the left seat, tried to get the airplane under control. Airspeed was about 220 knots and going higher, so he closed the throttles to keep the airspeed down. He still could not get the nose up; it felt to him as though the elevators were still on automatic pilot. He tried the elevator trim tab and could not turn it. After rapid loss of altitude to about 5,000 feet, the captain directed the first officer to assist him with the controls. Their combined efforts finally brought the nose up very rapidly but the aircraft then went into a steep climb. It turned sharply to the right about 180 degrees and, according to the captain, appeared to be on "the verge of a spin." Level attitude was regained by pushing the yoke forward, and by use of the rudder and aileron trim the turn was stopped. At an airspeed of 150 knots, flaps extended 25 degrees, buffeting decreased immediately, however., the aircraft continued to descend rapidly. Attempts to get rated power were futile and a message was broadcast that ditching was imminent. This message was sent at approximately 1106. The aircraft was then at an altitude of 500-1,000 feet. Ditching was imminent. Cabin attendants, realizing the emergency, assumed their respective stations for ditching. All passengers had been seated in the upper desk of the cabin with seat belts fastened and life jackets donned. The aircraft touched down under near ideal sea conditions with little swall. Contact with the water we severe and the impact dislodged life rafts from their storage bins and some seats were torn loose. The aft portion of the fuselage and empennage broke off at impact. Evacuation was orderly and the three rafts, although dislodged from their stowage receptacles, were launched without undue delay. The lanyards of all three life rafts were temporarily held at the cabin door by crow members. However, when one of the rafts was endangered by sharp metal of the broken fuselage its lanyard was released. Another was released by a crew member who then swam to that raft to right it. The lanyard of the third raft was released for unknown reasons. Consequently the rafts were carried away by the light surface wind. Passengers and crew left by both the main cabin door and escape hatches on both sides of the fuselage over each wing. Some crew members and passengers ware able to swim to and board the rafts. Three of the four fatalities, including the copilot and first engineer, were unable to do so and were lost. Members of the crew and passengers tried in vain to paddle to these persons. One other passenger later died in a raft from awe and shock. The purser, a woman, although suffering from shock swam and towed the only seriously injured passenger to the nearest raft, some 200 feet distant. The time of ditching was determined as 1112 and the position at lat. 43 degrees 48'15" N., long. 125 degrees 12'40" W., approximately 35 miles off the Oregon coast. The U.S.S. Bayfield, en route to Seattle, changed course toward the site and by add of search aircraft reached the life rafts some two hours later.
Probable cause:
The Board determines that the probable cause of this accident was loss of control and inability to maintain altitude following failure of the No. 3 propeller which resulted in wrenching free No. 3 Power package. The following findings were reported:
- Weather was not a factor in this accident,
- The aircraft and all its components functioned normally until a blade of No. 3 propeller failed,
- The resulting imbalance wrenched free No. 3 power package,
- Control difficulty resulted in rapid loss of altitude to low altitude,
- Fuel was not dumped,
- Rpm of the remaining three engines was not increased due to lack of specific training of the crew,
- This aircraft had not been notified in accordance with Service Bulletin No. 283; however, this information was available to the company,
- The aircraft was ditched under control approximately 35 miles off the Oregon coast,
- There were no fatalities as a direct result of the ditching,
- The three life rafts were launched without undue delay but were permitted to drift free,
- The aircraft floated for an estimated 20 minutes,
- Your persons succumbed as a result of shock, exposure, and/or drowning,
- Search and Rescue facilities were notified promptly and responded quickly and effectively.
Final Report:
