Circumstances:
On June 30, 1956, at 0901, Trans World Airlines Flight 2, a regularly scheduled passenger service, took off from runway 25 of the Los Angeles Inter-national Airport. Flight 2 was on an instrument flight rules (IFR) flight plan from Los Angeles, California, to Kansas City, Missouri, via Green Airway 5, Amber Airway 2, Daggett direct Trinidad, direct Dodge City, Victor Airway 10 Kansas City. The flight plan also proposed a cruising altitude of 19,000 feet, a .JPG"> airspeed of 270 knots, and a departure time of 0830. The Trans World flight crew consisted of Captain Jack S. Gandy, Copilot James H. Ritner, Flight Engineer Forrest D. Breyfogle, night Engineer Harry H. Allen (aboard as an additional crew member), and Hostesses Tracine E. Armbruster and Beth E. Davis. Preparations for Flight 2 were routine except that departure was delayed a few minutes by minor maintenance on the aircraft. The flight was dispatched with 3,300 gallons of fuel and the load manifest showed the gross weight of the aircraft at takeoff was 108,115 pounds, well, under the maximum allowable of 113,200 pounds. The load was properly distributed with respect to center of gravity limitations of the aircraft. As requested. the flight, after takeoff, contacted the Los Angeles tower radar departure controller, and was vectored through an overcast which existed in the Los Angeles area. After reporting "on top" (2,400 feet) the flight switched to Los Angeles Air Route Traffic Control Center (referred to as Los Angeles Center) frequency, 118.9 mcs., for its en route clearance. This clearance specified the routing as filed in the flight plan, however, the controller specified that the flight climb to 19,000 feet in VFR conditions. Immediately thereafter TWA 2 asked for a routing change to Daggett via Victor Airway 210. This was approved in a routine manner. At 0921, through company radio communications, Flight 2 reported that it was approaching Daggett and requested a change in flight plan altitude assignment from 19,000 to 21,000 feet. ARTC (Los Angeles Center) advised they were unable to approve the requested altitude because of traffic (United Air Lines Flight 718). Flight 2 requested a clearance of 1,000 feet on top. Ascertaining from the radio operator that the flight was then at least 1,000 on top, ARTC cleared the flight. At 0959 Trans World 2 reported its position through company radio at Las Vegas. It reported that it had passed Lake Mohave at 0955, was 1,000 on top at 21,000 feet, and estimated it would reach the 321-degree radial of the Winslow omni range station (Painted Desert) at 1031 with Farmington next. This was the last radio communication with the flight.
Probable cause:
The Board determines that the probable cause of this mid-air collision was that the pilots did not see each other in time to avoid the collision. It is not possible to determine why the pilots did not see each other, but the evidence suggests that it resulted from any one or a combination of the following factors: Intervening clouds reducing time for visual separation, visual limitations due to cockpit visibility, and preoccupation with normal cockpit duties, preoccupation with matters unrelated to cockpit duties such as attempting to provide the passengers with a more scenic view of the Grand Canyon area, physiological limits to human vision reducing the time opportunity to see and avoid the other aircraft, or insufficiency of en route air traffic advisory information due to inadequacy of facilities and lack of personnel in air traffic control. The following findings were reported:
- Approaching Daggett, TWA 2 requested its company radio to obtain 21,000 feet as an assigned altitude, or 1,000 on top,
- Company radio requested 21,000 feet IFR from ARTC. This vas denied by ARTC. Request was then made for 1,000 on top. This was approved and clearance issued. The flight climbed to and proceeded at 21,000 feet,
- As an explanation for the denial of 21,000 feet, TWA 2 was furnished pertinent information on UA718,
- The last position report by each flight indicated it was at that time at 21,000, estimating the Painted Desert line of position at 1031,
- The Salt Lake controller possessed both position reports at approximately 1013, at which time both flights were in uncontrolled airspace,
- Traffic control services are not provided in the uncontrolled airspace and according to existing Air Traffic Control policies and procedures the Salt Lake controller was not required to issue traffic information; none was issued voluntarily,
- A general overcast with some breaks existed at 15,000 feet in the Grand Canyon area,
- Several cumulus buildups extending above flight level existed; one was nearly over Grand Canyon Village and others were north and northeast in the area of the collision,
- The collision occurred at approximately 1031 in visual flight rule weather conditions at about 21,000 feet,
- The collision in space was above a position a short distance west of the TWA wreckage area, 17 miles west of or approximately 3-1/2 minutes' flying time from the Painted Desert line of position,
- Under visual flight rule weather conditions it is the pilot's responsibility to maintain separation from other aircraft,
- At impact the aircraft relative to each other converged at an angle of about 25 degrees with the DC-7 to the right of the L-1049. The DC-7 was rolled about 20 degrees right wing down and pitched about 10 degrees nose down relative to the L-1049,
- There was no evidence found to indicate that malfunction or failure of the aircraft or their components was a factor in the accident.

Circumstances:
The four engine christened 'Rafael Urdaneta' departed New York-Idlewild Airport at 2306LT and proceeded to the south. One hour and twenty minutes later, while flying along the US coast, the crew contacted ground and received the permission to return to New York following the failure of the number two engine. The crew was unable to feather the propeller and the aircraft suffered severe vibrations. Ten minutes later, while the crew was trying to dump the fuel, a fire erupted. The aircraft went out of control, dove into the sea and crashed about 40 miles southeast of New York. The airplane disintegrated on impact and all 74 occupants were killed.
Probable cause:
Although the accident was observed by witnesses, its cause cannot be determined with absolute certainty. However, it would be logical to assume that the vibration which resulted from the loss of control of propeller no.2 caused one of the inside wing attachments to loosen or break at some point between the fuel tank and the dump chute at the symmetrical point of vibration (behind engine no.3).

Circumstances:
Following an uneventful flight from Tampa, the captain started a night approach to Toronto-Malton Airport. During an ILS approach in poor weather conditions (300 feet ceiling), the four engine aircraft descended below the glide and hit the ground about 11 miles short of runway 10. It slid for 2,000 feet before coming to rest in flames. All 23 occupants were injured while the aircraft was destroyed.
Probable cause:
The Board of Inquiry found that the accident was caused by negligence on the part of the captain. The following findings were reported:
- The first officer, despite his duties which involved "In-Range" and "Pre-Landing" checks during the approach pattern, displayed an alertness concerning the procedures carried out by the captain, and on three separate occasions indicated to the captain conditions which required correction,
- The captain of the aircraft showed poor airmanship in the execution of his approach pattern, in that he made inadequate allowance for the strong prevailing wind and failed to utilize the ADF receiver to home on the outer marker,
- The captain failed to carry out an approved ILS let-down and, in so far as the position and the altitude of the aircraft were concerned, he ignored the indications of the ADF needle tuned to the marker, the ILS glide path needle and the altimeter,
- The captain ignored the warning from his first officer that he had descended below the regulation height,
- The captain was under the impression that he was very much closer to the airport than he actually was,
- The captain broke the regulations regarding the minimum altitude at which the glide path is to be intersected, the minimum altitude at which the outer marker is to be crossed, and the minimum altitude to which the aircraft may descend on the approach at Malton without becoming contact, and continued his descent until he flew into the ground.

Circumstances:
The aircraft was performing a flight from Patuxent River NAS to Port Lyautey, Morocco, with an intermediate stop at Lajes, carrying 21 crew members and 21 passengers, among them civilians and children. At 2330LT, the crew informed ATC about his position 400 miles east of Baltimore (Maryland), this was the last radio transmission. About an hour and a half later, while cruising at an altitude of 17,000 feet, the aircraft went out of control and crashed into the Atlantic Ocean without any distress call on part of the crew. SAR operations were conducted on a large area but were suspended six days later due to poor weather conditions. No trace of the aircraft nor the 42 occupants was found. It was reported by the board that the aircraft was also carrying 111 life vests, 46 exposure suits, 660 paper cups and 5 life rafts. All elements supposed to float. However, no trace of them was ever found.
Probable cause:
It is the opinion of the Board that R7V-1 registered 128441 did meet with a sudden and violent force, that rendered the aircraft no longer airworthy, and was thereby beyond the scope of human endeavor to control. The force that rendered the aircraft uncontrollable is unknown. The possibility of structural failure during transit of frontal weather cannot be discounted in this accident, but the possibility appears remote.

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:
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:
Northwest Airlines' Flight 8 departed Seattle-Tacoma Airport at 0148, September 6, 1953, for a nonstop flight to Chicago, Illinois. Gross weight on takeoff was 105,839 pounds; maximum allowable for takeoff was 116,740; maximum allowable for landing was 98.500 pounds. The location of the center of gravity was within prescribed limits. Weather at Seattle-Tacoma Airport during takeoff was: ceiling 200 feet and one-fourth mile visibility. Just after the aircraft became airborne No. 3 propeller oversped. Attempts by the flight engineer to correct this condition were unsuccessful and feathering was started one and one-half minutes later. However, the propeller continued to rotate at about 400 r.p.m. The flight's takeoff alternate was Yakima, Washington (a distance of 122 miles), but due to high terrain en route the captain elected to request clearance to proceed to Portland, Oregon (a distance of 132 miles), at 5,000 feet. This clearance was granted immediately. Using METO 2 power the aircraft reached 5,000 feet, well above the overcast, about 14 minutes after takeoff. Near the end of this climb the oil temperature of No. 4 engine was exceeding limits and the oil supply was being rapidly reduced. The flight engineer attempted to lower the temperature by fully opening the oil cooler flap. Temperature, however, remained high and the oil quantity continued to dwindle fast. Accordingly, the No. 4 propeller was feathered at about 0205 at the order of the captain who then declared an emergency and elected to land at McChord Air Force Base. Radio communication was established with McChord and arrangements made for a GCA approach after a short delay in establishing a frequency. No. 3 propeller had not feathered fully and was still windmilling at approximately 400 r.p.m. Meanwhile the captain had requested "takeoff" flaps, but the flaps would not extend hydraulically, and the copilot went to the cabin to crank them down. He stated that he turned the crank about 15-20 turns, at which point he found that it would no longer turn freely, whereupon he backed it to its original position. He was then called back to the cockpit to assist the captain in controlling the aircraft. Control difficulty had been continuously experienced with the aircraft yawing sharply and dropping a wing. The captain had placed the trim controls approximately in neutral, believing that he had a better feel and control of the aircraft without them at the recommended minimum speed of 130 knots. The aircraft, which had re-entered the overcast at about 2,000 feet, was then several miles from McChord Field under GCA direction on its first approach when its position and heading became such that the GCA operator directed a box pattern be flown to establish a proper approach. The second approach was executed in accordance with the directed pattern and the final approach was in line with Runway 34. The landing gear control was not actuated for gear extension until the aircraft broke out of the overcast at an altitude estimated at between 500 and 800 feet on a GCA controlled straight-in approach to Runway 34. At this time the captain ordered that No. 3 be unfeathered but it would not unfeather and continued to windmill. Only the right main gear extended fully and locked, as Indicated by its green light, but the landing was then committed. Shortly after touchdown retraction of the unlocked nose and left main gears allowed the aircraft to veer off the runway to the left. It then skidded sideways to its right, folding the right main gear inward, and the No. 2 engine was torn free. The aircraft came to rest on a heading of 212 degrees some 3,000 feet from the point of touch and about 7,000 feet short of the far end of the 10,000-foot runway. At about that time a gasoline fire started and spread rapidly over the ground below the airplane. Previously alerted fire apparatus, already standing by, kept the fire from spreading while all passengers and four of the crew left quickly by the main cabin door, the door sill being five or six feet above the ground. The flight engineer and the captain left by the cockpit crew door after ascertaining the cabin to be empty. All 32 occupants ware clear within an estimated two minutes. There were no fatalities although several persons were treated for burns at the McChord Air Force Base Hospital.
Probable cause:
The Board determines that the probable cause of this accident was a sequence of mechanical failures resulting in an emergency landing under adverse weather conditions with insufficient hydraulic pressure in the secondary system to extend fully the landing gear in the time available. A contributing factor was the design of the hydraulic system which did not permit use of the available pressure in the primary system for that purpose. The following findings were pointed out:
- Shortly after takeoff the aircraft lost the use of No. 3 engine due to an overspeeding propeller, and continued windmilling,
- Weather conditions at Seattle-Tacoma were satisfactory for takeoff but were below landing minimums and the captain elected to proceed to Portland,
- After reaching cruising altitude No. 4 propeller was feathered because of high engine oil temperature and depletion of oil supply,
- After losing the use of No. 4 engine, the captain declared an emergency and set up a GCA approach to McChord Air Force Base,
- A malfunction of the landing gear selector valve prevented normal use of the diminished hydraulic pressure to extend the flaps,
- A GCA instrument approach to McChord was necessary because of weather conditions. The captain decided that he would extend the gear only after breaking out under the low overcast,
- The short time interval between breaking out and touchdown was insufficient for extension and locking of all three landing gears with the existing hydraulic pressure,
- After touchdown the unlocked and partially extended left main and nose gears were forced up into their wheel wells with complete loss of control of the aircraft's ground movement, and fire occurred after rupture of the fuel tanks,
- The functional failure of No. 3 propeller governor was due to foreign metallic particles,
- The reason for the loss of oil supply for No. 4 engine was undetermined,
- The landing gear selector valve was improperly seated, resulting in insufficient hydraulic pressure.
