Investigation Summary
The flight from Kaduna was uneventful until the approach to Lagos, which was conducted during heavy rain and strong winds. Investigators found that the meteorological support at Lagos was poorly organized, resulting in the crew receiving unreliable wind data. During the final approach, the wind shifted to a tailwind component, contributing to the long landing. Despite the deteriorating conditions and the excessive touchdown point, the crew did not initiate a go-around. The runway was contaminated with a layer of water, causing the aircraft to aquaplane. The Tu-134 overran the runway end and collided with a concrete culvert located 147 metres beyond the runway. A significant factor in the fatality rate was a violation of cabin safety procedures regarding the placement of flight attendants. 15 passengers moved into the rear trunk and toilets after the crash, where they were overcome by smoke and fire. Rescue operations at the airport were also cited as being unsatisfactorily organized.
Final Conclusions
The accident was caused by a combination of crew error, environmental factors, and systemic failures. The primary causes included the crew's failure to execute a go-around after a long touchdown on a flooded runway, the lack of accurate weather and runway condition reporting by airport services, and the failure of cabin crew to manage passenger movement during the emergency, which led to fatalities in the rear of the airframe.

Airframe & Maintenance
Systems & Failure Modes
Braking System
The aircraft's wheel brakes were unable to decelerate the jet due to aquaplaning on a significant layer of standing water.
Meteorological Support
The airport's weather reporting failed to provide the crew with accurate wind direction and force during the critical landing phase.

- 02The aircraft landed with a tailwind component that the crew was not informed of by ATC.
- 03All 15 fatalities were attributed to asphyxiation and fire in the rear trunk and lavatories after the aircraft came to rest.
- 04The aircraft was 21 years old at the time of the accident.
- 05The airframe came to rest 147 metres beyond the runway end, striking a concrete drainage ditch.
