The Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR) did not record any data on this flight. Therefore, only information derived from Air Traffic Control (ATC) recordings, Aircrew interviews, aircraft inspection were used to compile the history of flight.
On 12 September, 2018 at about 20:20h, a Gulfstream IV (G-IV) aircraft with registration mark 5N-BOD operated by Skybird Air Limited on an Instrument Flight Rules (IFR) Flight Plan, departed Murtala Mohammed International Airport (DNMM) Lagos for Nnamdi Azikiwe International Airport (DNAA), Abuja on a post-charter return to base flight with One (1) person and Five (5) crew on board; with an endurance of four hours. The Captain was the Pilot Flying (PF) while the First Officer was the Pilot Monitoring (PM).
Earlier in the day at about 14:30 h, the Captain was attending a meeting at the company’s headquarters when he received notification for a charter flight to Lagos, departing Abuja at 16:30 h. The aircraft departed Abuja at about 18:10 h and landed in Lagos at about 19:05. The incident flight was the second and last flight to be operated by the crew for that day.
According to the crew, the aircraft departed Lagos at 20:20 h and climbed to Flight Level 350 (FL350) as cleared. The en-route weather was stormy almost all the way. Following an uneventful flight en-route, the aircraft was in contact with the DNAA Approach Radar and was given a clearance for Radar Vectors for an ILS approach RWY 22.
Radar instructed 5N-BOD to keep up to speed of 240 knots Indicated Air Speed (KCAS), being number one in the landing sequence for RWY 22. The aircraft intercepted Localizer (LOC) RWY 22 at about 15 NM to touchdown and slowed down to configure.
