Circumstances:
While cruising at an altitude of 4,000 meters by night, the crew contacted ATC to report his position and all was ok on board. About ten minutes later, the airplane disappeared from radar screens and crashed into the Atlantic Ocean about 180 km northwest of the Irish coast. SAR operations were dispatched on the scene and several debris and bodies were found in the early morning. All operations were suspended after few days and all 99 occupants were considered as deceased.
Probable cause:
On the basis of the evidence available and the investigation of possible serious threats to safety, the Board cannot establish the cause of the accident with certainty. Moreover, investigation of the possibility that the cause of the accident may have been a bomb explosion has yielded no conclusive facts to support such a hypothesis. The statements in the press to this effect have either been based on misunderstandings or else were tendentious. On the other hand, the Board attributes a high degree of probability to hypothesis that the cause of the accident is related to 'overspeeding' of one of the outboard propellers resulting from oil pollution after a gear had been damaged when the supercharger of the corresponding engine was accelerated (shifted). This probably took place close to the time of the accident. The overspeeding of the propeller, owing to the obstruction of metal particles in the regulator valves may have been such as to cause the propeller pitch to decrease and the propeller could not be feathered. The condition might provoke a flight disturbance which could be corrected only by prompt and powerful handling of aileron and rudder controls. in view of the rapidity with which this defect develops and taking into account that recognition of the nature of this malfunction requires a certain time, it is not always possible for the crew to intervene early enough to restore conditions of controlled flight. With respect to the presumed cause of the accident the Board has no grounds to suppose that the occurrence of the presumed malfunction might be attributable to neglect on the part of maintenance personnel or to incorrect measures taken by the crew or that the crew had been at fault in piloting the aircraft after the malfunction had occurred.

Circumstances:
After liftoff from runway 26 at Paris-Orly Airport, the four engine aircraft encountered difficulties to gain height, hit successively two houses, stalled and crashed in a huge explosion about 600 meters past the runway end. The aircraft disintegrated on impact and debris were scattered for about 200 meters. A passenger was seriously injured while all 34 other occupants, among them the Italian Director Guido Cantelli, were killed.
Probable cause:
The Commission was unable to find any malfunctioning of the aircraft or its equipment which would make it possible to determine why the aircraft followed the observed flight path. The Commission, therefore, believes that:
- the aircraft's slight loss of altitude soon after take-off was the main cause of the accident. There is no explanation for this loss of altitude,
- although the regulations in force were observed, the presence of unmarked obstructions in the take-off path constituted an aggravating factor,
- the initial and direct cause of the accident remains unknown.

Circumstances:
The aircraft departed from San Diego, California, at 0407LT on 12 July for Zurich Airport, Switzerland, with two American pilots at the control, on a delivery flight to Swissair. Intermediate stops included New York, Gander and Shannon. Having left New York at 1240 GMT on 14 July 1956, the aircraft landed at Gander at 1659 GMT. After a stop of 57 minutes, it left Gander for Shannon at 1748 GMT carrying the same crew of 4 members. Following an uneventful ocean crossing the aircraft at 0008 hours on 15 July was given initial descent clearance to Shannon and was then cleared into the Shannon Holding Pattern, where four other aircraft were holding. At 0125 hours the aircraft commenced a Ground Controlled Approach to runway 23 and on establishing visual reference to the ground broke off the approach for a left-hand visual circuit to runway 05. During the turn onto final approach to runway 05, the aircraft, while banking steeply was observed to drop. The aircraft was destroyed on impact with the ground at approximately 0135LT and the 4 occupants were killed. There was no fire.
Probable cause:
The probable cause of the accident was an error of judgment by the pilot, resulting in the execution of an abnormally steep turn onto final approach during which the aircraft slipped into the ground.
Possible contributory factors were:
- That for the successful execution of an approach involving a steep turn near the ground on a very dark night, there had been insufficient visual guidance from the terrain,
- Impairment of the pilots' proficiency due to the length of the period on duty.

Circumstances:
After a night takeoff from runway 32 at Shannon Airport, the four engine aircraft christened 'Triton' climbed to a maximum height of 260 feet and reached the speed of 155 knots when it went into a slight nose down attitude. It then started to descend until it crashed into the Shannon Estuary, about 8,170 feet from the departure end of runway 32. The crashed occurred approximately 35 seconds after liftoff. 28 occupants were killed while 28 others were rescued. The aircraft was destroyed.
Probable cause:
- Failure of the captain to correlate and interpret his instrument indications properly during flap retraction, resulting in necessary action not being taken in sufficient time. This failure was partially accounted for by the effect on instrument indications of inadvertent and unexpected gear re-extension,
- Loss of aircraft performance due to inadvertent landing gear re-extension,
- The captain failed to maintain sufficient climb to give him an opportunity of meeting unexpected occurrences.

Circumstances:
The crew started the approach to Gander Airport by night and in good weather conditions. Following a stabilized approach, the four engine aircraft landed normally on runway 32. After touchdown, the reverse thrust system were activated when the aircraft veered to the left. Despite several corrections on part of the flying crew such as braking action, movement on the nose wheel steering and power added on both left engines number one and two, the aircraft continued down the runway, overran, lost its undercarriage and came to rest into a ravine. While all 67 occupants were evacuated safely, the aircraft was damaged beyond repair.
Probable cause:
The approach configuration to Gander Airport was correct and the aircraft was stabilized until touchdown. No technical anomalies were found on the aircraft and all piloting techniques were normal. The analysis of the aircraft's path after touchdown did not show any trace of rough braking action. An exam of the pilot reports indicated that the aircraft was quite difficult to be maneuvered during a turn to the right. At the time of the accident, a lateral wind was blowing to 16 knots, which could be considered as a contributory factor.

Circumstances:
While approaching Amsterdam-Schiphol Airport after an uneventful flight from New York via Shannon, the crew received the permission to descend to 5,500 feet and then 4,500 feet and 3,500 feet respectively. At 1130LT, the four engine aircraft christened 'Willem Bontekoe' disappeared from the radar screens after it crashed into the sea. About five minutes after the disappearance, ATC cleared the crew to descend to 2,500 feet but did not receive any feedback. SAR operations were hampered by poor weather conditions and first debris were found at 1610LT about 37 km northwest of Ijmuiden. None of the 21 occupants survived the crash and less than 50% of the aircraft was recovered.
Probable cause:
Investigations were unable to determine the exact cause of the accident. Nevertheless, a number of hypothesis as to the cause of the accident were developed. Some possibilities considered were:
- overheating of the electric system with heavy smoke development,
- explosion of one of the high pressure bottles,
- failure of a cockpit window,
- failure of the automatic pilot system.
However, no hypothesis could be formulated in which all occurrences and evidence could be made reasonably acceptable. Therefore, in November 1955, after a 15-months' period of intensive investigation, the conclusion had to be drawn that the cause of the accident could not be established.

Circumstances:
Air France Flight 075 originated at Orly Field, Paris, August 2, 1954, with a crew consisting of Captain Jean Caboche, Copilot Jean Roussean, Navigator Jacques Geffard., First Flight Engineer Albert Grandvaux, Second Flight Engineer Jean-Baptiste *** Stewardess Francine Dono, First Steward Michael Gallet, and Second Steward Jean Capron. The dispatch office had prepared two flight plans - one for a stop at Gander, Newfoundland, the other with a stop at Shannon, Ireland. Owing to marginal weather at Gander with the forecast indicating no improvement, the captain chose the latter plan. The flight departed Paris at 2024 and arrived Shannon at 2247. Fuel tanks were filled and the pilots ware briefed on weather for the nonstop flight to New York. Flight 075 departed Shannon at 0003 the next morning (August 3), estimating 11 hours 49 minutes an route, with fuel for nearly 14 hours. The gross weight at takeoff, 126,100 pounds, was less than the maximum allowable 133,000, and the load was correctly distributed relative to the canter of gravity of the aircraft. The Atlantic crossing was uneventful. Routine position reports were made en route and the flight periodically received weather reports for points along the route and at the destination. Stronger headwinds than had been anticipated were encountered near the North American continent, resulting in lower ground speed and somewhat higher fuel consumption per mile. The flight had approximately 600 gallons of fuel left at 1230 when it reported over Scotland Intersection (15 statute miles southwest of New York International Airport) and received clearance for an ILS approach. It was then 38 minutes behind its original flight plan estimate made at Shannon and had approximately 100 gallons less fuel than anticipated. During the approach, which was being monitored by New York International Airport radar, the flight encountered unexpected heavy turbulence, heavy rain, and a low ceiling, and the captain discontinued the approach at 1237 (0737 e. s. t.) when near his minimum prescribed altitude of 200 feet. The heavy turbulence made control of the aircraft difficult and when the missed approach was made, the captain found himself left of the localizer and below of glide path. The tower, which was immediately advised of the missed approach, told the flight to turn right to 130 degrees (the missed approach course), proceed to Scotland Intersection, and climb to 2,500 feet. Approximately three minutes after the missed approach and while on the 130-degrees course, the flight requested clearance to Boston. Such clearance was issued nine minutes later, as soon as possible consistent with other traffic. Meanwhile, the flight had reported being low on fuel but when asked if an emergency as being declared replied, "Negative, negative, not yet." At the approximate time clearance to Boston was received the flight engineer advised the captain that they had fuel of one more hour of flight. Thirty-three minutes after being cleared to Boston, the flight, at that time in the vicinity of Providence, Rhode Island, called Providence Tower, declared an emergency, and requested weather information. Providence weather, which was marginal, was furnished and the flight was cleared for an approach. However, the pilots found that their navigation kit did not contain an approach plate for Providence Airport and they advised they were not landing there. The captain then descended through a break in the overcast, circled two or three times, and landed with the gear retracted in a field at Preston City, Connecticut. It came to rest in flames in a garden and was destroyed by a post crash fire. All 37 occupants were evacuated safely. Nevertheless, 12 occupants were injured, among them both pilots.
Probable cause:
The Board determines that the probable cause of this accident was inadequate in-flight planning, in that the captain did not make a firm selection of a suitable airport within range of the fuel remaining at the time of the missed approach, necessitating an off-airport landing. The following findings were reported:
- All fuel tanks were filled to capacity during the scheduled stop at Shannon,
- Owing to headwinds the flight had approximately 100 gallons less fuel than anticipated when it arrived over Scotland Intersection, southwest of New York International Airport,
- In the ILS approach to New York International Airport during instrument weather conditions, the flight encountered an unexpected severe local storm with greater turbulence, heavier rain, and a lower ceiling than weather reports had led them to anticipate, and the captain discontinued the approach at 1237,
- The captain decided not to attempt another approach to New York International Airport and instead requested clearance to Boston at 1240 while climbing on the missed approach course,
- The flight was asked by New York International Airport Approach Control if an emergency was being declared, but the copilot replied in the negative,
- An IFR clearance to Boston was issued by New York ARTC at approximately 1249, the flight in the interim having been routed toward Boston via Mitchel range station,
- When the flight reported over Mitchel range station at 1250, the flight engineer advised the captain, upon the latter's request, that there was fuel for one more hour of flight,
- Difficulties with communications after being cleared from ARTC frequency prevented the flight from receiving the dispatcher's suggestion to proceed to Bridgeport or Hartford,
- Testimony of the pilots indicated that the captain intended to land at an intermediate airport between New York and Boston if he could find one with sufficiently good weather conditions,
- There were no language difficulties in conversations with the flight,
- There was sufficient fuel available to fly to Boston or any intermediate airport, but the fuel remaining over Boston, had the flight continued to that point, would have allowed only about 17 minutes of flight thereafter,
- Flight 075 declared an emergency at 1322 (0822 e. a. t.) in its first contact with Providence Tower/INSAC, indicated intention to land at Providence, was cleared for an approach, and then at 1329, advised that they were not landing there,
- The flight descended through a break in the overcast and made an emergency landing at about 1340 (0840 e. s. t. ) in a field and without loss of life.

Circumstances:
While approaching Gander in poor weather conditions, ATC instructed the crew to divert to Sydney, Nova Scotia. On final approach, the aircraft was too low and hit three approach lights. Immediately, the pilot in command increased power but as both left engines were damaged by obstacle impact, they failed to respond properly. As a result, the left wing stalled and the aircraft crashed in flames few dozen yards short of runway. All 31 occupants were able to evacuate the cabin and the crew extinguished the fire. Unfortunately, thirty minutes later, another fire erupted on the left side of the aircraft, partially destroying the airplane. Carrying 2,5 tons of cargo, the aircraft christened 'Zürich' was performing a regular schedule flight from Zurich to New York via Geneva, Shannon and Gander.
Probable cause:
The impact of the aircraft with the ground while out of control due to failure on the part of the captain to maintain sufficient height to clear the approach light poles, three of which were struck by the aircraft. After striking the approach light poles, the captain and first officer were unable to maintain control of the aircraft due to the malfunctioning of numbers 1 and 2 engines and structural damage to the left wing and flap.

Circumstances:
The flight departed from Rome, Italy, at 1608, August 14, 1949, carrying 49 passengers and a crew of nine, 2,260 gallons of fuel, and 2,750 pounds of baggage and cargo Aircraft weight at time of takeoff was 68,646 pounds, which was within the allowable limit of 70,700 pounds No information is available as to whether the aircraft was properly loaded with respect to its certificated center of gravity limits According to the instrument flight clearance filed with Rome Air Traffic Control, the planned route was to Marseille, France, at an altitude of 10,500 feet, then direct to Shannon, Ireland, at an altitude of 8,500 feet Orly, the principal commercial airport at Paris, France, was designated as the flight's alternate Clear weather and light to moderate winds over the proposed route were predicted. Takeoff from Rome was made by First Officer Hall as pilot with Captain Bessey serving as copilot After leveling off at 8,500 feet, 2,000 feet below the planned cruising altitude to Marseille, Captain Bessey retired to the crew's quarters, and the flight continued with First Officer Hall flying as pilot Second Officer John Moore was co-pilot, James Baumann was navigator, Robert D Thomas and Herbert Ashbell were radio officers, and Ralph Fisher and Luigina Cerabona were flight attendants The ninth member of the crew, Ruth Nichols, had no assigned duties. Except for the fact that the number 3 engine operated roughly when the mixture was in auto lean, the flight progressed without incident At approximately 2300, the flight descended to 3,500 feet, which was above a layer of stratus clouds. The original ETA (estimated time of arrival) of 0021 over Shannon was revised several times en route, but all such times passed without the flight observing the Shannon Airport Actually, although unknown to the crew, at 2300 the aircraft had been flown beyond Shannon and was over the North Atlantic It was not until 0050 or later that a turn was made for the return course to Shannon. At 0106 the flight alerted Air-Sea Rescue facilities at Shannon and gave its position as 100 miles west of Shannon, flying inbound on a track of 80 degrees Ground speed was estimated to be 140 knots The flight continued toward Shannon until 0240 when all fuel was exhausted, and at which time the aircraft was ditched, seven miles northwest of Lurga Point on the Irish Coast No use was, made by the flight of 500 KC's, the International Distress Frequency. The aircraft remained afloat for about 15 minutes, during which time the crew and the passengers removed and manned all but one of the life rafts Aircraft circling over the life rafts were able to direct the British trawler "Stalberg" to the scene. All rescue operations were completed shortly after daylight of August 15, 1949. Seven passengers and one crew member died as a result of exposure or drowning, all others were successfully rescued. The aircraft sank and was lost.
Probable cause:
The Board determines that the probable cause of this accident was the failure of the captain to exercise the proper supervision over his crew during flight planning and while en route.
The following findings were noted:
- The crew did not confer during flight planning, and did not have any agreement or accurate knowledge as to route, fuel hours an board, fuel requirements, or duration of flight,
- Weather information which was obtained at the time of flight planning was not obtained for the route which was flown, and no attempt was made en route to secure such information,
- Accurate hourly positions of the aircraft were not determined or plotted, nor was celestial navigation used as a routine means of position determination, though the stars were visible at all times after sunset,
- The flight passed over the immediate vicinity of Mizen Head, Ireland, at 2227 at which time it erroneously reported its position to Shannon radio as being over Land's End, Great Britain,
- The flight continued beyond destination until approximately 0050, at which time a turn was made in the vicinity of 53 27 degrees north latitude End 18 20 degrees west longitude for return to Shannon,
- All fuel was exhausted at 0240, necessitating a ditching at a point approximately seven miles northwest of Lurga Point on the Irish Coast.
Final Report:
