Scheduled Revenue Flight

The mechanic in charge of taxiing the Boeing 727 allowed an unauthorized avionics technician to occupy the pilot seat. They inadvertently deactivated the brake pressurization system and struck a passenger jetway at the terminal gate. An ensuing fire destroyed the airplane and a company ground vehicle and extensively damaged the jetway. The terminal gate was also damaged. A total of 11 persons were injured.

While cruising in poor weather conditions, the twin engine aircraft struck the slope of a mountain located in the region of Canaima. All 10 occupants were killed, among them nine tourists.

At takeoff, the engine failed and the aircraft crashed. Occupant fate unknown.

Taxi clearance was received at 16:35 and the flight left gate 14B for runway 19. The airplane was cleared for takeoff at 16:44. Shortly after lifting off, at 200 feet above the ground, the engine torque gauges began to fluctuate erratically and the plane began to yaw back and forth. The captain believed the TTL (Torque Temperature Limiting) system may have been bypassing fuel to the engines (a situation that could occur when power levers are advanced too far forward). He then slightly decreased the power settings which resulted in even greater torque oscillations and greater yawing. The captain believed both engines were malfunctioning for some unknown reason and landed back on runway 19, because a 90° turn for runway 28 seemed impossible. The aircraft overran the runway, struck a 6 feet high chain link fence, struck a concrete barrier and skidded across the Route 61 highway before coming to rest on a parking lot.

On final approach in poor weather conditions, the aircraft struck trees, stalled and crashed in the jungle few km from the airport. All eight occupants were killed.

At 10:18 flight LO5055 took off from Warsaw runway 33 for a flight to New York-JFK. The aircraft headed for the GRU VOR, which it passed at FL265, climbing to FL310. Two minutes later (at 10:41) the n°2 engine Low Pressure turbine shaft broke loose, followed by the failure of the turbine disc. Debris punctured the aft fuselage, causing a fire in the cargo hold. The elevator control system was severed and the n°1 engine had to be shut down. The flight crew immediately started an emergency descent to 4,000 metres. After shutting down both n°1 and n°2 engine the crew mistakenly thought the fire was extinguished. They had decided to land at Modlin airport, but still unaware of the fire, changed to Warsaw-Okecie runway 33 because of better rescue equipment there. The flight started a left turn for runway 33 at 11:09 at an altitude of 1,450 metres and an airspeed of 480 km/h. The crew lost control during the turn and the Il-62 crashed into a forest, 6 km from the runway at an airspeed of 465 km/h and an 11° left bank and 12° nosedown. The aircraft disintegrated on impact and all 183 occupants were killed.

On May 8, 1987, flight 5452, a commuter flight regularly scheduled to depart from San Juan, Puerto Rico, at 0615 local time, for a flight to Mayaguez, Puerto Rico, departed at 0620 with four passengers and two crewmembers. The captain was 15 minutes late when he arrived for the flight at 0600. The first officer arrived on time at 0545. The airplane, a CASA C-212~CC, was operated by Executive Air Charter, Inc., doing business as American Eagle. The flight was on a visual flight rules flight plan, and communications with the flight en route were reported to have been routine. The first officer handled the initial radio communications, and the captain made subsequent radio communications. While in the vicinity of Mayaguez, the captain cancelled the flight plan and proceeded to make a visual approach to runway 9. The captain did not make the customary in-range call to the operations agent at Mayaguez to report the flight’s arrival estimate and fuel requirements. Witnesses who observed the airplane on its downwind leg reported that it appeared normal. One witness said the airplane seemed too fast on the approach and appeared to overshoot the extended centerline on the baseleg turn to final. Another said the airplane “turned tighter” and did not extend the downwind leg as normal. He said as the airplane came toward him, the nose rose up quickly and then the airplane rolled to the right and nosed over. A third witness said the airplane made a violent turn, and he thought the engine noise was louder than normal. A fourth confirmed that the airplane made a shortened downwind leg, making a continuous left turn and sinking fast. He said that it turned rapidly to the right and nosed down and struck the ground. He then saw it pivot around and slide backwards. He stated that fire began when the right wing and engine separated from the airplane. A fifth witness, a company baggage handler, said he heard an explosion and saw flames come out of the right engine before it turned twice and struck the ground. A crop duster pilot reported that everything appeared normal until the airplane was about 1,000 feet from the runway and about 100 feet above the ground. He said at that point, he heard a sound similar to that of a turbo propeller airplane going into reverse pitch to slow down after landing. He said the airplane then yawed to the right, followed by a roll to the left, as if the pilot had attempted to counteract the yaw. The airplane then rolled back to the right and the right wing tip struck the ground. A fire erupted immediately, the airplane turned about 1800, and it came to rest upright. The four passengers on board reported that the flight was routine until the approach into Mayaguez. One passenger seated in 3A noticed that the noise from the engines was lower than usual and that it was not the normal engine sound. He thought afterward that perhaps an engine had stopped and that the noise was different on the right. He said the airplane was not shaking or vibrating. A second passenger seated in 4C reported that the airplane lost altitude abruptly and that it fell rapidly as it banked to the left on the approach. He said he heard strange sounds from the left side and that it was an engine or scraping noise. He stated that he saw a 1 l/2- to 2-foot long flame come from the left engine, but that it did not appear to be spreading. He reported that the airplane jerked before it hit the ground. The third passenger, seated in 6A, reported that she heard an unusual metallic sound similar to a landing gear retracting or extending immediately before the crash. The fourth passenger in seat 78 was asleep and did not awaken until the crash. He said that he thought the airplane made a hard or gear-up landing.

Following an uneventful flight from Chiang Mai, the crew initiated the approach to Chiang Rai Airport in good weather conditions. The copilot was the pilot-in-command when the aircraft completed a gear up landing. It slid on runway for about 1,075 meters before coming to rest on the runway. All 43 occupants escaped uninjured while the aircraft was damaged beyond repair.

Crashed after the crew got distracted in flight. There were no casualties.

Suffered an accident somewhere in Taiwan. There were no casualties.
