United States of America

Before takeoff, pilot was advised of IFR conditions along 1st part of route, with flight predictions for occasional moderate turbulences below 15,000 feet and mixed icing from freezing level (6,000 feet) to 18,000 feet. He filed IFR flight plan with cruise altitude of 11,000 feet. During departure, pilot was cleared to climb to 9,000 feet and told to expect clearance to 11,000 feet 5 minutes later. Radar data showed aircraft climbed at about 1,500 feet/minute and 100 knots, slowing slightly above 8,000 feet. At abt 9,000 feet, aircraft started to level and accelerate. It then climbed momentarily, deviated laterally from course and entered steep descent. Inflight breakup occurred and wreckage was scattered over 4,100 feet area. Trajectory study showed breakup occurred between 4,500 feet and 6,500 feet as aircraft was in steep descent in excess of 266 knots. Metallurgical examination of wings and stabilizers revealed features typical of overstress separation; no pre-existing cracks or defects were found. The aircraft was recently purchased. Pilot's son indicated principal problem was 'twenty year leap in technology' from previously owned PA-24, that pilot had difficulty with avionics and flight director/autopilot, and that he lacked detail training in autopilot emergencies. Both occupants were killed.

During a scheduled cargo flight, the pilot diverted from the normal route and travelled through mountainous terrain. The radar plot indicated that the airplane was in a gradual climbing left turn when the collision occurred. The weather in the area at the time of the accident reported snow showers in the mountainous area. The pilot, sole on board, was killed.

The aircraft was completing a flight from Tampa to Detroit on behalf of the Detroit City Police. After landing on runway 15 at Coleman A. Young Airport, the airplane encountered difficulties to stop within the remaining distance, overran and came to rest. All six occupants escaped uninjured while the aircraft was damaged beyond repair.

The pilot detected an unacceptable sink rate on short final approach and initiated a go-around. After applying power and retracting the landing gear, the left wing dropped and struck the runway. The aircraft then ground looped and came to rest with substantial damage. The pilot escaped uninjured while the aircraft was damaged beyond repair.

The aircraft was en route at 31,000 feet, when the low pressure fuel filter warning light illuminated. The pilot diverted toward Columbia, MO, but before reaching Columbia, both engines lost power. Subsequently, the aircraft crashed about 2 miles east of the airport. An investigation revealed the fuel was contaminated with water. The fuel filter deicing system was operational, but a post-accident examination revealed the deicing tank was empty. This was the 2nd flight since the deice tank had been serviced. The manufacturer's info indicated the supply tank should have provided about 3 to 4 hours of filter deicing operation. One of the pilots was killed.

The pilot failed to deice the wings prior to the takeoff and overloaded the airplane by 360 lbs structurally and 1,100 lbs for flight in icing conditions. There was moderate snow falling at the time of takeoff. The takeoff roll was described as long and a witness saw the wings rocking from side to side after takeoff. The airplane struck trees one mile off the end of the runway, crashed and burned. Post accident investigation found snow contamination on the top of one wing that did not burn and the top of the horizontal stabilizers and elevators. No discrepancies were found with the engine or airframe. Both occupants were killed.

The Cessna 208B made a takeoff with light wet snow falling, at night. The airplane reached an altitude of 700 feet agl prior to making a steep descent, striking trees and impacting inverted. Radar data showed the aircraft lift off point and initial climb rate approached that shown in the flight manual for short field technique. Two other Cessna 208's preceded the accident aircraft from the same airport, one 13 minutes prior and the other 3 minutes prior. Radar data showed they climbed at a slower rate. The accident airplane had come from a hangar and was not deiced prior to departure. A pilot flying a identical airplane with a similar load commented that his climb rate was lower than normal. Another pilot commented that this was the first wet snow of the year and it was sticking to his engine cowling. The pilot, sole on board, was killed.

Avianca flight 052 (AV052), a Boeing 707-321B with Colombian registration HK-2016, crashed in a wooded residential area in Cove Neck, Long Island, NY. AV052 was a scheduled international passenger flight from Bogotá, Colombia, to New York-JFK Intl Airport, NY, with an intermediate stop at Jose Maria Cordova Airport, near Medellín, Columbia. Of the 158 persons aboard, 73 were fatally injured. Because of poor weather conditions in the northeastern part of the United States, the flightcrew was placed in holding 3 times by ATC for a total of about 1 hour and 17 minutes. During the 3rd period of holding, the flightcrew reported that the aircraft could not hold longer than 5 minutes, that it was running out of fuel, and that it could not reach its alternate airport, Boston-Logan Intl. Subsequently, the flightcrew executed a missed approach to JFK Intl Airport. While trying to return to the airport, the aircraft experienced a loss of power to all 4 engines and crashed approximately 21 miles northeast of JFK Airport.

During arrival, heavy rain showers were reported west of airport. At the airport, the weather was about 200 feet obscured with fog and drizzle, wnd was easterly at 5 to 7 knots. The pilots intended to land on runway 22, but after being told the wind was gusting to 27 knots, they elected to land on runway 04. The actual wind was not gusty. The erroneous gust indication was from a malfunction of the LLWAS. On final approach for an ILS runway 04 approach, the flight was advised the wind was from 030° at 5 knots and the RVR was 1,800 feet. Minimum RVR for the approach was 2,400 feet. The crew acknowledged; 22 seconds later, the ELT activated as the aircraft touched down 1,600 feet short of runway 04 and hit approach lighting system, railroad tracks and a fence. Investigations revealed the aircraft descended thru windshear. While maneuvering onto final approach; ground speed varied between 320 and 190 knots as aircraft was maneuvered thru tailwind to headwind near faf. CVR data verified a delay in descent from 4,000 feet to 1,900 feet before reaching faf and that the gear warning horn sounded before extension of gear and speed brakes. There was evidence of low engine rpm during impact, but no preimpact mechanical problem was found. Each pilot had over 10,000 hours of flight time, but only about 160 hours each in jet aircraft. All seven occupants were killed.

During arrival at night, Beechcraft A100 (King Air, N44UE) was cleared for an ILS runway 26R approach behind Continental flight 9687, then Eastern Airline (EA) flight 111 (Boeing 727, N8867E) was cleared for the same approach behind the King Air. After landing, flight 9687 had a radio problem and the tower controller had difficulty communicating with flight 9687. Meanwhile, the King Air landed and its crew had moved the aircraft to the right side of the runway near taxiway Delta (the primary taxiway for general aviation aircraft). The turnoff for taxiway Delta was about 3,800 feet from the approach end of runway 26R. Before the King Air was clear of the runway, EA111 landed and converged on the King Air. The crew of EA111 did not see the King Air until moments before the accident. The captain tried to avoid a collision, but the Boeing's right wing struck the King Air, shearing the top of its fuselage and cockpit. Some of the King Air's strobe/beacon lights were inoperative, though they most likely would have been extinguished for the IMC approach. The local controller did not issue a traffic advisory to EA111 with the landing clearance. One of the pilot on board the King Air was killed while the second was seriously injured.
