On 5th November 2019, at about 07:35 h, a Boeing 737-500 aircraft with nationality and registration marks 5N-BUJ departed Lagos for Owerri with 84 persons on board and six (6) crew members, as APK7004. The Co-pilot was the Pilot Flying (PF) and the Pilot was the Pilot Monitoring (PM). The flight operated on an Instrument Flight Rules (IFR) flight plan.
At 07:40:16 h, the aircraft was in contact with the Lagos Area Control centre (ACC) which cleared it to climb to FL310 and proceed direct to ARAGU.
The Co-pilot reported, “at about 23,000 ft, there was a loud bang and the automation went off and the airplane veered a little to the right. The second bang came a few seconds after the first and we quickly glanced at the primary engine instrument panel and noticed that N2 indication was zero, N1 was also rapidly decreasing and was at about 30% while we were climbing”.
