Circumstances:
As Flight 211 approached Los Angeles, clearance was given to pass over the Los Angeles Municipal Airport, and the tower there relayed to the crew information received from a previous flight to the effect that ground fog conditions in the area were general Shortly after 0540 the tower transmitted a special weather observation as, "Roger 211, special, at 0540 clear, visibility one mile ground fog". Accompanying remarks contained in the Weather Bureau report, "Ground visibility one-half mile, variable from one quarter to three-quarters mile, estimated 10 to 50 feet deep, were omitted. A shallow left turn was made over the airport, after which the prelanding cheek list was accomplished. A procedure turn was then executed east of the field and a landing approach was made to Runway 25L. According to the pilot the runway approach lights remained clearly visible, though small puffs of clouds were encountered during the approach. Flaps were fully extended when the airplane passed over the boundary of the field. Before touching down on the runway, a thick formation of ground fog was encountered. Visibility was reduced to practically zero. Contact with the runway, 2,300 feet from the approach end, was made with sufficient impact force to deform the wing structure and deflect the No. 4 engine nacelle downward to the extent that the No. 4 propeller struck the runway. Following the landing fire was observed in the area of the No. 4 engine nacelle. Brakes were vigorously applied. The aircraft rolled forward in a slight left turn, coming to rest 1,500 feet from the point of landing, and 197 feet from the left edge of Runway 25L. Flames rapidly engulfed the right wing and fuselage but all passengers were deplaned without serious injury. The airplane had been observed by the tower on the landing approach, though fog obstructed it from view just before it passed over the airport boundary. The tower also observed it over the runway, at which time it appeared to be flaring out for a normal landing. After that the airplane could not be observed because of fog. Several calls were made by the tower to Flight 211 but no acknowledgements were received. Noticing a reddish glow on top of the fog approximately where the flight had disappeared, the tower called Pan American Operations, located near Runway 25L, and was informed that something was burning on the runway. At 0558, six minutes after the aircraft landed, the tower called the Los Angeles Fire Department and asked them to investigate. Equipment on the airport was promptly dispatched and it arrived at the scene of the accident about two minutes later. By the time fire equipment arrived, however, the aircraft was practically destroyed. All 23 occupants were rescued.
Probable cause:
The Board determines that the probable cause of this accident was the pilot's inability to see the runway after entering a ground fog during a final approach and landing.
The following factors were considered as contributory:
- Weather information received prior to the flight's departure from Phoenix, Arizona, in addition to reports obtained en route, indicated that at the time of arrival over Los Angeles, California, ground fog conditions would prevail at the Los Angeles Municipal Airport.
- A weather report, given to the flight when it arrived over the vicinity of the airport, stated that visibility on the field was one mile, and the remarks accompanying the weather observation "ground visibility one-half mile, variable one-fourth to three-fourths mile, ground fog estimated 10 to 50 feet deep" were omitted.
- The flight made its approach for a landing on Runway 25L at the Los Angeles Municipal Airport and encountered ground fog before making contact with the runway.
- As a result of losing visual reference to the runway and the ground, control of the aircraft was lost before the landing was completed.
- Contact with the runway was made 2,300 feet from the approach end and was sufficiently hard to cause structural failure and fire.

Circumstances:
At 1210 the flight called the Wilmington-New Castle Tower and asked to be cleared for an instrument approach to runway one. The flight advised that they would fly law over the field on their first approach, and that they would then circle and land The approach was made, and the aircraft flew low over the field to the immediate right of runway one. After passing the north end of the runway. a climbing left turn was made to an altitude of 400 to 500 feet. The aircraft circled at that altitude until approximately one mile west of the south end of runway one, then it started a gliding left turn, toward the field. One-half mile south of the airport the turn was completed, and the aircraft flew a straight course on final approach toward runway one for landing. This last turn onto final approach was completed at an altitude of 200 to 300 feet. The landing gear was down, but the flaps were not extended. The descent on final approach continued normally until the aircraft had reached an altitude of approximately 50 feet above the ground, at which time it was 500 to 1,000 feet from the approach end of runway one. Then, the aircraft was observed to assume a nose-high attitude and to descend more rapidly. First contact with the ground was made 130 feet Prom the approach end of runway one, and 22 feet in front of a 5-foot embankment. The top of this embankment was level with the runway. Since the embankment was uniformly covered with sod, it was not discernible from the air. The extreme loads which were imposed upon the aircraft structure as it rolled into and over the rising embankment immediately after it had settled to the ground caused considerable damage to the landing gear, fuselage, and wings. Forced back into the air by the rise of the embankment, the airplane landed for the second time on the runway, skidding forward 1,270 feet. The right wing was torn from the fuselage as the aircraft turned over to an inverted position. Fuel spilled from ruptured gasoline tanks ignited, and the wreckage burst into flames.
Probable cause:
The Board determines that the probable cause of this accident was the inadvertent landing of the aircraft short of the runway.

Circumstances:
At 0135 the flight transmitted a report to Shannon Radio indicating its position as over the Irish coast at 7,000 feet. At this time the flight was cleared to cross the Limerick marker at 5,000 feet. Shortly thereafter Shannon Radio advised the flight of the Shannon weather. Visibility 2 miles, 10/10 cloud cover at 900 feet, 3/10 at 500 feet, wind 160 degrees, 5 knots, altimeter setting 30 04 inches. At 0153 the flight reported over the Shannon radio range station at 5,000 feet and was given clearance to descend on the SE leg. While in the procedure turn at 0200 the flight transmitted a position report to Shannon Radio and, in acknowledgement, received a later Shannon weather report. Rain and drizzle, visibility 2 miles, 10/10 cloud cover at 900 feet, 6/10 at 400 feet, wind 120 degrees, 5 knots, altimeter setting 30 04. Receipt of this weather retort was acknowledged and the Shannon control tower cleared the aircraft for approach to Runway 14. At 0206 the flight reported over the range station at 1,200 feet at which time Shannon Tower advised Aircraft 505 that Shannon was reporting 10/10 cloud cover at 400 feet, 4/10 at 250 feet, visibility 1 mile, wind 120 degrees, 5 knots. Upon receiving acknowledgement from the flight Shannon Tower requested the pilot to make a ceiling check. This request was also acknowledged by the flight. At approximately 0208 personnel at Shannon Airport observed Aircraft 505 approach the field on a heading parallel to Runway 32. The aircraft appeared to continue on this heading until over the airport at which time it turned to the right to a heading of approximately north. Shortly thereafter the aircraft disappeared from sight. At approximately 0209 these observers saw a brilliant flash WNW of the airport and heard a loud noise. Realizing that Aircraft 505 had crashed, tower personnel immediately initiated rescue operations and dispatched emergency crews to the scene of the accident.
Probable cause:
The board determines that the probable cause of this accident was an error in altimeter indication, the primary reason for which was the reversal of the primary and alternative static source lines which leg the pilot to conduct his approach, to the airport at a dangerously low altitude. A contributing factor was the negligence of maintenance personnel in certifying to the satisfactory functioning of the static system although the tests required to determine such a condition were not accomplished. A further contributing factor was the restriction of vision from the cockpit resulting from fogging of the unheated windshield panels.

Circumstances:
The crew was performing a positioning flight to Wilmington-New Castle Airport to pick up passengers. On approach, the crew was informed by ATC that weather conditions were poor and that it should be better to divert to Philadelphia. The pilot attempted to land on runway 14 but after touchdown, he realized his mistake and elected to go around. It was too late, the aircraft overran, went through the perimeter fence, crossed a road where it hit two cars and continued for about 650 feet before coming to rest in flames. While all eight crew members escaped unhurt, the aircraft was destroyed.
Probable cause:
At the time the aircraft arrived in the vicinity of New Castle, a line squall was approaching the airport. Although advised by the tower to proceed to an alternate airport, the captain elected to land at New Castle Airport. Although advised by the tower of a wind shift of approximately 145 degrees, and the availability of a suitable runway into the wind, the captain elected to continue a wind approach to Runway 14. During the final approach the precipitation increased from light drizzle to heavy showers. At the time of the landing the tailwind component along Runway 14 was at least 16 mph. The aircraft failed to make contact with the ground until having passed over 2,100 feet of the runway. The aircraft failed to decelerate completely within the remaining 3,100 feet of the runway. When it became apparent that the aircraft would not stop on the runway, the pilot applied power in an unsuccessful attempt to become airborne. The aircraft continued beyond the end of the runway, through the trees bordering the airport, across DuPont Parkway, and came to rest in an open field. After coming to rest the aircraft was almost totally destroyed by fire. The Board determines that the probable cause of this accident was the poor judgment of the pilot in continuing in his attempt to land on a wet runway with a tailwind component in excess of 16 mph after having passed 2,100 feet of the runway.

Circumstances:
The aircraft climbed to an altitude of 3,000 feet to an area approximately four miles east of the Reading Airport at which time, at the instruction of Captain Brown, Captain Nilsen leveled off to begin practice of instrument approach procedures. Shortly thereafter, the flight crew detected an odor resembling burning insulation, but did not immediately determine the source. At approximately 1137, the slight engineer went aft in order to determine the origin of the smoke. Upon opening the galley door, he observed that the entire cabin was filled with a very dense smoke and he returned to the cockpit and reported to Captain Brown that "the whole cabin is on fire". The crew immediately attempted to combat the fire with the cockpit fire-extinguisher but were unable to enter the cabin because of the dense smoke and intense heat. The smoke quickly filled the cockpit through the open galley door, rendering visibility extremely poor and making it difficult for the pilots to observe the instruments. The student flight engineer opened the cockpit crew hatch in an attempt to clear the cockpit of smoke, however, the opening of the hatch increased the flow of smoke from the cabin toward the cockpit and shortly thereafter it became impossible for Captain Brown to observe any of the instruments or to see through the windshield. Captain Brown opened the window on the right side of the pilot compartment and attempted to fly the aircraft back to the Reading Airport for an emergency landing while descending with the engines throttled and with his head out of the side window. With the increased intensity of the heat and denseness of the smoke in the cockpit, it became impossible for the pilots to maintain effective control of the aircraft. At an altitude of approximately 100 feet, two miles northwest of the airport, Captain Brown withdrew his head from the window and attempted to "ditch" the aircraft "blind". The aircraft contacted two electric power wires strung about 25 feet above the ground, and the left wing tip glanced against scattered rocks and struck the base of the large tree. The aircraft settled to the ground, slowly rotating to the left, as it skidded approximately 1,000 feet across a hay field, causing disintegration of the left wing panel, flaps and aileron. The aircraft continued to yaw to the left and, after having rotated more than 90 degrees, it plunged through a row of trees and telephone poles lining a road bordering the field, coming to rest in a pasture at a point approximately 150 feet beyond the road and pointing approximately 160 degrees from its original heading at the time of initial impact. Gasoline was spilled from the ruptured tanks and fire broke out consuming the major portion of the wreckage. When local farm workers arrived at the scene approximately one minute after the aircraft had come to rest, Captain Brown was observed walking away from the wreckage and Captain Nilsen was seen lying on the ground to the rear of the trailing edge of the right wing approximately six feet from the fuselage Both pilots were taken to the Reading Hospital where Captain Nilsen died shortly afterward. The remaining four crew members died in the wreckage.
Probable cause:
The Board determines that the probable cause of this accident was failure of at least one of the generator lead through-stud installations in the fuselage skin of the forward baggage compartment which resulted in intense local heating due to the electrical arcing, ignition of the fuselage insulation, and creation of smoke of such density that sustained control of the aircraft became impossible. A contributing factor was the deficiency in the inspection systems which permitted defects in the aircraft to persist over a long period of time and to reach such proportions as to create a hazardous condition.

Circumstances:
After takeoff, while climbing to a height of some 600 feet, the left engine failed. The crew informed ATC about the situation and obtained the permission to return for an emergency landing. While trying to restart the left engine, the right engine failed as well. The aircraft stalled and crashed on a railway road located few hundred yards from the runway threshold. While the aircraft was damaged beyond repair, all 21 occupants were evacuated with minor injuries.
Probable cause:
The probable cause of this accident was the complete loss of power in both engines due to fuel starvation necessitating an emergency landing in an unfavorable area. The cause for fuel starvation of the engines has not been determined.

Circumstances:
The flight was cleared to Washington National Airport by the Washington control tower and Instructed to use Runway 21 However, because it had been necessary to bear to the left when northeast of the airport to a position from which approach to Runway 21 was, not practicable, the flight was asked by Washington Tower if it desired to use a right-hand. Pattern for Runway 36 The flight replied that it desired clearance for Runway 27, and, as the wind was calm, Washington Tower approved this request. The flight approached the field from the northeast and while over the east bank of the Potomac River approximately 2/3 of a mile from the boundary of the airport, turned to the right and started a descent in final approach to Runway 27. According to the testimony of the pilots, Initial contact was made with the runway between 800 and 1,000 feet from the approach end and the aircraft continued down the runway with less than normal deceleration, Approximately 600 feet from the far end of the runway the pilot attempted a turn to the right. After turning approximately 30 degrees, the aircraft rolled beyond the runway end and struck a concrete transformer housing. The aircraft whipped approximately 90 degrees to the right and came to rest across a drainage ditch with its empennage extending over the highway which adjoins the airport. All twelve occupants were evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The Board determines that the probable cause of this accident was the poor judgement of the flight crew in attempting to land from a position which did not afford sufficient time to accomplish a satisfactory approach. A contributing factor was the peer landing technique of the pilot in falling to reduce the air sufficiently for a safe landing. A further contributing factor was the lack of knowledge on the part of the crew concerning the poor braking action of rubber tires on a wet runway.
Final Report:
