The solid state based memory in the CVR was in good condition and retained 31 minutes of audio information. The digital tape based memory in the FDR succumbed to the post crash fire and melted, consequently no data could be recovered. (Emphasis added.)The CVR's information starts as the aircraft is approaching Lagos Muhammed Murtala Airport (LOS) on its fourth flight segment of the day. The captain and first officer are discussing a "non-normal condition" concerning the "correlation" between the MD-83's throttle setting and engine power indication/engine pressure ratio. Investigators underscored that the crew did not initially express concern that the problem would "affect the continuation of the flight."
During the next 25 seconds until the end of the CVR recording, the flight crew was attempting to restart the engines. The airplane crashed in a residential area about 5.8 miles north of LOS.
The wreckage was "approximately" on the extended centerline of Runway 18R. All 153 people on the aircraft were killed, as were 10 on the ground.
