Investigation Summary
The approach was conducted in challenging weather conditions, with visibility reported at only 450 meters in heavy rain. As the Trident 2E descended toward Runway 31, it deviated below the normal glide path. The right outboard trailing edge wing flap struck the innermost approach light, and the right main gear tyres hit the facing edge of the runway promontory. The impact forces were sufficient to rip the gear assembly from the wing structure. The aircraft briefly became airborne again before impacting the runway surface 600 meters further down. It then veered right, crossed the grass safety strip and a parallel taxiway, and plunged into the sea. The fuselage broke in a way that separated the cockpit, which became submerged. Rescue divers were unable to reach the trapped flight crew in time to prevent their drowning. The investigation was significantly hampered by the absence of a Cockpit Voice Recorder (CVR) and the use of a primitive Flight Data Recorder (FDR) that provided limited parameters. Furthermore, the Precision Approach Radar (PAR) at Kai Tak had failed to maintain a lock on the aircraft due to the intensity of the rain, depriving the crew of external guidance during the critical final stages of the approach.
Final Conclusions
The Hong Kong Civil Aviation Department report stated there was insufficient evidence to determine the definitive cause of the accident. However, it concluded that the final approach became unstable and that windshear may have contributed. The final deviation below the approach path was likely caused by a sudden reduction and distortion of visual references due to heavy rain. The report also noted that the accident was survivable, but fatalities were exacerbated by the crew's failure to wear shoulder harnesses and the lack of proper seating for a sixth crew member in the cockpit.

Airframe & Maintenance
Systems & Failure Modes
Landing Gear
The right main landing gear was completely sheared off after striking the runway promontory during the undershot approach.
Shoulder Harnesses
The flight deck crew were not wearing their shoulder harnesses at the time of impact, which contributed to the severity of their injuries.
Emergency Equipment
The aircraft lacked basic safety equipment including passenger lifejackets and safety information leaflets.
Interesting Facts
- 01The aircraft was a British-built Hawker Siddeley Trident 2E delivered in 1973.
- 02Visibility at the time of the accident was approximately 450 metres (1,480ft).
- 03Six of the seven fatalities were crew members who drowned in the submerged cockpit.
- 04The aircraft was not carrying passenger lifejackets despite the approach being over water.
- 05A sixth crew member was seated in the cockpit on an unsecured metal stool.
- 06Autopsies confirmed the cockpit crew died from drowning rather than impact trauma.
- 07The aircraft was not equipped with a Cockpit Voice Recorder (CVR), and the Flight Data Recorder (FDR) was a primitive model.
- 08The Precision Approach Radar (PAR) failed to provide guidance due to heavy rain interference.
Safety Actions & Advisories
Safety Equipment Mandates
The investigation highlighted the critical absence of lifejackets on over-water approach paths, leading to recommendations for mandatory flotation devices on all flights into Kai Tak.
Crew Restraint Compliance
The report emphasized the necessity of using shoulder harnesses and secured seating for all occupants in the cockpit during critical phases of flight.
