While cruising in bad weather conditions, the twin engine aircraft struck the slope of a mountain located in the region of Ayacucho. As the aircraft failed to arrive at destination, SAR operations were initiated but suspended few days later as no trace was found. Walkers found the wreckage in an isolated area on 28 August 1990.

Circumstances:

After takeoff from Manila-Ninoy Aquino Airport, while climbing to an altitude of about 400 feet, the crew reported engine problems and elected to return for an emergency landing. Shortly later, the aircraft banked right, lost height and nosed down by an angle of 70° before crashing onto a house located in the district of Paranaque, about one km from the airport. The aircraft and the house were destroyed. All 21 occupants as well as four people on the ground were killed.

Probable cause:

Failure of the right engine during initial climb for undetermined reasons. It was reported that the crew failed to follow emergency procedures which was considered as a contributing factor. When the right engine failed, the aircraft was still in takeoff configuration with flaps and gear down.

Circumstances:

Parked at Manila-Ninoy Aquino Airport, the aircraft was ready for its flight to Iloilo City with 114 passengers and a crew of six on board. While being pushed back, the aircraft suffered three explosions and caught fire. 80 people escaped with minor injuries while 31 others escaped uninjured. Unfortunately, eight passengers died.

Probable cause:

It was determined that the center fuel tank had not been filled nor purged since March 9. It is possible that fuel vapors that accumulated in the central fuel tank ignited with the combination of high temperature (actual OAT 35° C) and a defect electric wire.

Circumstances:

On final approach to Tuxtla Gutiérrez Airport runway 35, while the aircraft was fully configured for landing, the crew decided to initiate a go-around procedure for unknown reasons and completed a left turn in an attempt to make a 180 circuit. The aircraft lost height, struck trees and crashed 3,200 meters short of runway threshold, bursting into flames. All four crew members and 20 passengers were killed while 16 other occupants were injured.

Probable cause:

The loss of control on final approach was the consequence of a loss of lift after the crew failed to maintain a minimum speed while initiating a go-around procedure. At this time, the aircraft was fully configured for landing with flaps and landing gear down.
The following contributing factors were reported:
- Lack of crew coordination,
- Lack of crew experience on this type of aircraft.

Captain / Total flying hours:

Circumstances:

After touchdown at New Delhi-Indira Gandhi Airport following an uneventful flight from London-Heathrow Airport, the crew started the braking procedure and activated the thrust reversers when the pylon of the engine n°1 failed. The engine partially detached, causing a fuel line to rupture and the fuel to ignite. The aircraft was stopped after a course of almost 3 km and all 215 occupants were evacuated safely. The fire was extinguished but the aircraft was damaged beyond repair.

Probable cause:

The accident was caused due to the migration of the improperly installed diagonal-brace aft fuse-pin of the No.1 engine from its fitting which substantially reduced the load carrying capability of the engine fittings resulting in failure of the upper-link forward fuse pin due to excessive loads on account of probably improper landing leading to a partial separation of engine and fire.

Circumstances:

At 2043 eastern daylight time (EDT), Frontier Air Flight 1602, C-GFAW, a Beechcraft C99 Airliner, took off from Timmins, Ontario, on a scheduled domestic flight to Moosonee, Ontario. The aircraft carried a two-pilot crew, two passengers, and approximately 60 pounds of freight and baggage. The flight proceeded, via airways, to Moosonee at 7,000 feet above sea level. At 2121 EDT, the flight was cleared for an approach at Moosonee with a temporary altitude restriction of 5,000 feet. The crew elected to fly the very high frequency omnidirectional range (VOR) runway 24 approach. At 2129 EDT, the crew reported on the 061° radial of the VOR at five nautical miles (nm) outbound. Shortly after intercepting the 061° radial inbound, the crew initiated a descent to the 440-foot minimum descent altitude (MDA). While in the descent, the aircraft broke through the lowest cloud layer at 900 feet asl, approximately 9.2 nm from the VOR. At this point, both pilots had the runway lights in sight, and the captain decided to change to a visual approach and proceed inbound at 700 feet asl. Shortly after advising the co-pilot of his intentions, the captain initiated the before-landing cockpit check and selected the landing gear lever to the DOWN position. Immediately thereafter, the aircraft struck trees and crashed seven miles east-northeast of the Moosonee Airport. One of the pilot was killed while three other occupants were injured.

Probable cause:

It was determined that the captain inadvertently flew the aircraft into trees, during a condition of visual illusion, as a result of inadequate crew coordination in that neither pilot effectively monitored the altimeter. Contributing to the occurrence were the absence of approach lighting, the lack of company crew pairing policy, the captain’s unfamiliarity with black-hole illusion and the seating position of the captain.

Circumstances:

During the takeoff roll at Luang Namtha Airport, after V1 speed, the crew started the rotation when the flight engineer decided to abort the takeoff procedure without any coordination with both pilots. Unable to stop within the remaining distance, the aircraft overran and collided with a building. All 35 occupants were rescued while one person on the ground was killed.

Probable cause:

It was determined that the crew failed to prepare the flight according to published procedures. Prior to departure, the crew incorrectly calculated the weight and balance and it was determined that the aircraft has been incorrectly loaded as the CofG was too far forward, out of the enveloppe. Poor crew coordination was a contributing factor.
