Convair CV-240

The aircraft had landed at Palam at 1902 hours following an uneventful flight from Karachi. A thorough service check was carried out, and it was refuelled and loaded for the return flight to Karachi. The total take-off weight indicated on the load sheet was 41 589 lbs. The investigation revealed an error in the empty weight of the aircraft and the actual gross take-off weight was determined to be 41 319 lbs, which is 1 181 lbs less than the maximum permissible all-up weight. At 2018 hours the aircraft commenced its take-off run and was airborne at the latter half of the runway. Soon afterwards flames were observed at the western boundary of the airfield. The crash crew chief had watched the aircraft take-off. He saw the aircraft becoming airborne and then climbing to a height estimated by him to be 50 ft. He then noticed the landing lights pointing downwards and the aircraft losing height. He feared that a crash was imminent and immediately instructed the crew to proceed in that direction. At about this time the crash siren was sounded. The crash tender reached the site of the accident in about 7 to 8 minutes by which time the fire had reached large proportions. Fatal injuries were sustained by 4 members of the crew, 17 passengers and 2 others who were in the vicinity of the crash. Nine passengers and one other were seriously injured. The aircraft was destroyed by impact and fire.

The crew was conducting a local training mission at Warsaw-Okecie Airport. On final approach, the four engine aircraft went out of control, stalled and crashed in a field short of runway. All four crew members were injured and the aircraft was damaged beyond repair.

This was scheduled passenger flight 535 of March 1 from Boston, Massachusetts, to New York, New York, with stops planned at New Haven and Bridgeport, Connecticut. The crew, consisting of Captain Edward W. Johnson, First Officer Norman A. Paquette, and Stewardess Marian Sullivan, reported to company operations at Boston well ahead of scheduled departure time. Departure from Boston at 0927 was on time and was in accordance with an TFR clearance to cruise at 6,000 feet via airways to New Haven. The flight was routine and on schedule to New Haven. The aircraft was not refueled during the five-minute stop at New Haven, during which time both engines were stopped. The flight departed the terminal with five passengers and 1460 gallons of fuel. Gross weight of the aircraft was well under the maximum allowable and its center of gravity was located within prescribed limits. The wind was calm and runway 14 (4,116 feet), one of two macadam runways, was selected for takeoff. There is no air traffic control tower at New Haven. After completion of the takeoff checklist, the aircraft moved onto the runway and takeoff was initiated from a tan start without delay. This segment of the flight was being flown by First Officer Paquette who occupied the right seat. Captain Johnson, on the left, maintained directional control during the initial acceleration of the aircraft. Before the aircraft reached the intersection of runways 14 and 19, the landing gear was retracted. The aircraft then skidded clown runway 14 near its center and cane to rest 1,050 feet from the far end. Captain Johnson, Stewardess Sullivan, and three passengers left through the right emergency escape hatch over the wing. First Officer Paquette and the two remaining passengers left through the partially opened front entrance door. Fire, around the left engine and the left outboard wing area, caused considerable damage and was extinguished by the local fire department.

About 1342 Flight 19 took off from runway 31. The takeoff appeared normal, and the aircraft climbed to approximately 500 feet above the ground. At this time several ground witnesses saw two or more silvery pieces separate from the aircraft. Most witnesses said the pieces seemingly separated from the area of the right wing. Almost simultaneously the aircraft was observed to nose down sharply and descend at a steep angle. As it neared the ground it leveled off considerably but continued to descend. It contacted the ground raising a large cloud of dust and then disappeared from the view of the observers behind intervening higher terrain. Seconds later large columns of smoke were seen rising from the accident site. During the ground roll the aircraft struck large boulders in its path and fire occurred which consumed the major portion of the aircraft. There were no fatalities but serious injuries resulted to 5 of the 18 passengers and minor injuries to most of the others. The crew of three received minor or slight injuries.

Flight 327 was scheduled between Providence, Rhode Island, and Tulsa, Oklahoma, with intermediate stops including Chicago, Illinois; and St. Louis, Springfield, and Joplin, Missouri. The flight to Chicago was routine; however, the crew, when securing the cockpit, observed that the fire-warning light for the forward cargo and electrical accessory compartments flickered. This was called to the attention of both the ground crew and the relieving crew (a routine crew change was made) and was written in the aircraft log. Because of necessary repairs to the fire-warning system the flight was delayed 1 hour, 40 minutes and it departed Chicago at 1950. The new crew consisted of Captain Wesley G. Mims, First Officer Paul H. Johnson, and Stewardess Shirley D. Walker. Flight 327 was routine to Joplin and it departed there at 2323 with seven passengers aboard. Leaving Joplin the aircraft weighed 35,940 pounds, which was well under the allowable gross takeoff weight; the load was properly distributed. The flight was cleared by ARTC (Air Route Traffic Control) to the Owasso “H” facility, 2 via airway V-88, to maintain 4,000 feet, and to contact Tulsa approach control on crossing the south course of Chanute low frequency range for further clearance. At approximately 2333, 10 minutes after takeoff from Joplin, ARTC, through the company radio, advised the flight to climb to 4,500 feet, to maintain 4,500 feet, and to report leaving 4,000. This transmission was acknowledged and flight 327 reported leaving 4,000 feet at 2334. Approximately 10 minutes later company radio at Tulsa gave the flight the Tulsa 2328 weather sequence. The company then gave the flight the local altimeter setting as 30.15 and field pressure as 460 feet above zero. This was acknowledged and flight 327 reported it was changing over to Tulsa approach control frequency. At 2347 the flight reported crossing the south leg of Chanute low frequency range and was immediately cleared by approach control direct to Owasso, to descend to and maintain 3,500 feet, and to report when over Owasso. The 2328 Tulsa weather was given the flight as: Measured ceiling 600 feet, overcast; visibility 2-1/2 miles; very light drizzle and fog; wind calm. Liter, the flight reported it was 1-1/2 minutes from Owasso and asked if any delay was expected. Approach control advised no delay was expected since the only local traffic was then making an ILS (Instrument Landing System) approach. Shortly thereafter approach control advised flight 327 that the visibility was then 1-3/4 miles, that the U.S. Weather Bureau was checking the ceiling, and asked if an Owasso approach straight in to runway 17 was to be mad or if an ILS approach was preferred. The flight advised it would make the Owasso approach and at 2357 was cleared accordingly. It was asked to report when over the Owasso facility inbound. At 2400 flight 327 reported over Owasso, inbound, and was cleared to land on runway 17L. Two minutes later a special 2355 weather observation was transmitted to the flight as: Measured 200, overcast; visibility 1-3/4; very light drizzle and fog. This transmission was not acknowledged and nothing further was heard from the flight. Repeated efforts by approach control and other facilities to contact the flight were unsuccessful.

Flight 476 of August 4 was a scheduled operation between Tulsa, Oklahoma, and La Guardia Field, New York, with several intermediate stops including Joplin, Springfield, and St. Louis, Missouri. The flight departed Tulsa at 1006 (one minute behind schedule) with Captain Hugh C. Barren, First Officer William G. Gates, and Stewardess Thelma R. Ballard as crew. En route stops were made at Joplin and Springfield, and no discrepancies were reported or noted at either point. However, a traffic delay in the Joplin area resulted in the flight arriving and departing Springfield 21 minutes behind schedule. Two of the eight passengers deplaned at Springfield, 21 passengers boarded the flight there. Gross weight of the aircraft at takeoff was 38,663 pounds, 2,302 pounds under that allowable, and the center of gravity was located within prescribed limits. Flight 476 departed Springfield VFR for St. Louis, its next scheduled stop, at 1153 via Victor Airway 14 to cruise at 7,000 feet. It was off the ground at 1156. Twenty-one minutes later (1217) the crew initiated a general call asking, "Does anyone read 476?" Springfield company radio acknowledged but received no reply. Two other American Airlines flights, one cruising in the vicinity of Springfield at 7,000 feet, the other 30 miles north-northeast of St. Louis, heard a transmission from Flight 476 that No. 2 engine was on fire. This message was also heard by American's ground station at St. Louis. Three minutes later the American flight in the Springfield area intercepted the following message, "Springfield, are you reading 476? We have bad engine fire." This was the last message heard from the flight. All transmissions were on company frequency. During this interval numerous witnesses on the ground back along the flight path saw the aircraft with smoke and flame coming from the right engine. The aircraft was also tracked by a military radar installation near Springfield until it disappeared from the scope in the vicinity of Fort Leonard Wood. At approximately 1222 the operations officer on duty at Forney Field, Fort Leonard Wood, received a radio message from an Army pilot flying nearby that a two-engine aircraft with a fire in the right engine was on final approach to runway 14. The tower operator at Forney Field saw the approaching aircraft and gave it clearance to land. Before the operations officer could alert the crash crew another call from the Army pilot informed him that the airplane had crashed short of the runway. The time was 1223. Army personnel with portable fire-fighting equipment reached the wreckage on foot. There were no survivors. Heavy fire-fighting equipment and ambulances could not reach the scene until the Army engineers had bulldozed a road through the densely wooded area in which the crash occurred.

American 711 reported en route to the company that it was over Vichy (a position along Victor Airway 14 about 100 miles from Springfield) and estimated it would reach the Springfield VOR station at 2233. Initial radio contact with Springfield Approach Control was established at 2218 and the flight gave it the same Springfield estimate. The approach controller transmitted the 2208 weather observation to the flight. Reported conditions were: Ceiling 400 feet overcast; visibility 10 miles; wind west 12; altimeter 29.68. In response to the controller’s question the flight then indicated it intended to land at Springfield. Immediately thereafter clearance was issued for a standard range approach, instructing flight 711 to report over the range station and when starting the procedure turn. Shortly thereafter the flight asked clearance to descend. There being no other traffic the controller cleared the flight for an approach and to descend whenever it wished. At 2229 the latest weather observation for the airport, completed at 2228, was transmitted to the flight. Conditions given were: Ceiling 500 feet overcast; visibility 8 miles, very light drizzle; wind west 10. The flight informed the controller it would make a circling approach to runway 31, the active runway. At 2234 the flight reported, “American 711, over the Omni at 34, proceeding to the field.” Approximately two minutes later an explosion was seen and heard north-northwest of the airport and attempts to contact the flight thereafter failed. The aircraft crashed about 0,25 miles short of runway 31 and was destroyed. Both pilots and 11 passengers were killed. A weather observation immediately following the accident was: Ceiling 500 feet overcast; visibility 5 miles, very light drizzle; wind northwest 8; altimeter 29.66.

The aircraft, engaged on a scheduled flight non-stop from Ezeiza to Córdoba, took off from Ezeiza Airport at 1500LT with 27 passengers and 5 crew. The approved flight plan provided for a VFR flight at a cruising level of 1,200 meters. At 1510LT the aircraft asked Buenos Aires ATC for clearance to change its altitude to 600 meters due to a marked frontal belt having been encountered. Shortly after this, the aircraft entered a storm area with rain, hail and strong electrical discharges of increasing intensity which caused uncontrolled loss of altitude. It continued descending until it struck the ground at approximately 1520LT, injuring the pilot, two crew and four passengers.

While overflying The Channel by night at an altitude of 12,000 feet, the port engine stopped. The captain feathered its propeller, informed ATC about his position and obtained the permission to divert to Manston Airport. Few minutes later, the right engine failed as well. The crew decided to ditch the aircraft about 12 km off Folkestone. After one hour, four crew members and two passengers were rescued by the crew of a boat while three other passengers drowned. The aircraft later sank and was lost.

Western Air Lines' Flight 314 departed Los Angeles, California, on a scheduled flight to Minneapolis, Minnesota, with intermediate stops scheduled at Las Vegas, Nevada; Cedar City and Salt Lake City, Utah; Casper, Wyoming, and Rapid City, South Dakota. The flight was routine to Salt Lake City, where a relief crew consisting of Captain M. R. Cawley, First Officer R. E. Crowther and Stewardess Mary Grace Creagan took over the flight in accordance with company crew assignment schedules. Prior to departure from Salt Lake City the aircraft was refueled to a total of 1,000 gallons, which filled all tanks, Flight 34 departed from the Salt Lake City ramp at 0721, but returned a few minutes later because of a broken nose wheel steering cable. The cable was replaced and Flight 34 was off the ground at 0850. According to company records, at takeoff the gross weight was 36,990 pounds, 2,144 pounds less than the maximum allowable weight of 39,134 pounds; the load was properly distributed so that the center of gravity of the aircraft was within approved limits. There were an passengers. The flight plan filed with Air Route Traffic Control specified Instrument Flight Rules at 15,000 feet via Green 3 and Blue 76 Airways. Eastward from Salt Lake City the Casper weather went below company minimums and Flight 34 elected to overfly this scheduled stop. After being advised of this action by the company Casper radio, Air Route Traffic Control issued a new clearance for the flight to descend to and maintain 13,000 feet to the Rapid City range station via Blue 37 and Red 2 Airways. However, an altitude change to 17,000 feet was requested by the flight and this was authorized by ARTC. At 1010 N8407H reported 17,000 over Casper, estimating the Wright intersection (122 miles west of Rapid City) at 1027. The Flight reported as being over the Wright intersection at 1025, at 17,000 feet, estimating Rapid City at 1050. The Casper company radio operator gave the flight the 0930 en route weather and the 1010 Rapid City Special #2 terminal weather. This, the last radio contact, was acknowledged by the flight at 1027. At 1041 the Rapid City radio operator attempted unsuccessfully to contact the flight to deliver a clearance for an instrument approach to Rapid City. Attempts continued until 1053 and at that time the Denver company dispatcher was advised that contact with the flight had been lost. At 1106 emergency procedures were initiated. Intermittent snows and restricted visibilities hampered intensive air search efforts. The wreckage was sighted by a Western Air Lines pilot the afternoon of February 28, and ground parties reached the scene that night. The aircraft had crashed in an isolated ranch area and all nine occupants had been killed.
