The Accident Investigation Bureau Nigeria (AIB-N) has released two preliminary reports on incidents involving aircraft owned and operated by Air Peace Limited and Max Air.
Air Peace Boeing 737-500 aircraft with nationality and registration marks 5N-BUJ was enroute Sam Mbakwe Airport, Owerri on 5th November, 2019 when the incident occurred at about 23,000 feet above Mean Sea Level (FL230).
On the other hand, Max Air Boeing 747-400 aircraft with nationality and registration marks 5N-DBK occurred at Runway 05, Minna International Airport on 7th September, 2019.
The reports are already on the Bureau’s website.
For AirPeace incident, the bureau listed the following findings: the pilots were qualified and licensed to fly the aircraft, the first officer was the Pilot Flying (PF) and the captain was the pilot monitoring, the captain took control of the aircraft at FL230 after the loud bang and yaw, the aircraft had a valid Certificate of Airworthiness and metal debris were found around the tail cone of No. 2 engine during post-occurrence inspection.
For Max Air incident, the bureau stated during the incident, the aircraft crossed the threshold right of centre line, was in a left bank, the left main wheels touched down and the number one engine nacelle contacted the runway on the centre line, 203 m from the threshold, and was dragged on the runway along the centre line for approximately 44 m.
AIB further explained that the body wheels touched down, followed by the right main wheels and the aircraft gradually steered to the centre line.
“On examining the number one engine, the bottom surface of the nacelle was abraded, thereby releasing the cowl latches resulting in the fan cowls being blown off the engine by the slipstream.”
The bureau observed that damage was done to the bottom intake of engine number 1, fan cowl (left and right) on engine number one and the thrust reverser cowl on engine number one.
It further observed that the left wing was punctured and damage was done to the transfer tube between angle gear box and main gear box
The bureau therefore recommended that Nigerian Airspace Management Agency (NAMA) should ensure that the Navigational Aids installed at all the operating airports in Nigeria are calibrated in accordance with the AIP Supplement S 38/2019.
“The Federal Airports Authority of Nigeria, (FAAN) should always ensure that there is effective control of birds and wild life during airport operating hours at Minna Airport,” AIB added.
