Ethiopian Airlines flight ET3901, a Boeing 737-800F, from Addis Ababa to Lagos, diverted to Lomé due to adverse weather conditions in Lagos. In Lomé, the aircraft landed without incident and was parked in position S10A. Following a storm accompanied by strong winds, the aircraft rotated nearly 90° to the right, at around 04:25. During its rotation, it struck mobile airstairs located at the left front door, causing significant damage to its left wing and the vehicle.
Cause
The commission identified the main cause as the presence of the airstairs at the aircraft's front left door at the time when the weather conditions deteriorated.
Contributing Factors
- Failure to apply procedures in case of deteriorating weather conditions by all parties involved.
- Absence of ground handling agents during the closing of the front door during the storm.
- Lack of coordination between the crew and the ground handling company during this period.
