This is the preliminary finding of Nigeria’s Accident Investigation Bureau (AIB) that was released last week.
The first sign of trouble started at 3:41 PM local time when the first officer asked the captain…”both engines coming up?”.
The reply from the Captain was negative:
‘At 15:41:16, the first officer (FO) inquired, “both engines coming up?” and the captain (Capt) replied “negative.”
The flight crew subsequently discussed and agreed to declare an emergency. At 1542:10, Dana 992 radioed an emergency distress call indicating “dual engine failure . . . negative response from throttle.”
At 1542:35, the flight crew lowered the flaps further and continued with the approach and discussed landing alternatively on runway 18L.
At 1542:45, the Capt reported the runway in sight and instructed the FO to raise the flaps up and 4 seconds later to raise the landing gear.
At 1543:27 hours, the Capt informed the FO “we just lost everything, we lost an engine. I lost both engines”. During the next 25 seconds until the end of the CVR recording, the flight crew was attempting to restart the engines, the report said.’
The MD-80 plane crashed 5.8 miles north of Lagos according to the report.
The report also stated information regarding the impact:
“…the impact sequence, the Dana plane struck an incomplete building, two trees and three buildings and the wreckage was confined, with the separated tail section and engines located at the beginning of the debris field.”
Testing of fuel samples from the refueling truck were negative for contaminants.
