Accident Investigation Bureau (AIB) was notified of the accident by the Nigeria Airspace Management Agency (NAMA) on 20th February, 2018. Investigators were dispatched the following day, arrived on site at 11:00 h. All relevant stakeholders were notified accordingly.
On 20th February 2018, DANA Flight 0363 (DAN0363) a Boeing MD-83 aircraft, operated by DANA Airlines, was on a scheduled flight from Nnamdi Azikiwe International Airport (DNAA) Abuja to Port Harcourt International Airport (DNPO) on an Instrument Flight Rules (IFR) flight plan. Onboard were 44 passengers, 2 pilots, and 3 flight attendants. Initially, the First Officer was the Pilot Flying (PF) while the Captain was the Pilot Monitoring (PM).
At 18:47 h, the Captain took over control after realizing the Distance Measuring Equipment (DME) 2 was not serviceable.
The aircraft descended through approach minimums (460 feet AGL) on a localizer only approach runway 21, crossed the threshold and did a smooth touchdown on the runway at 7,972 feet from threshold. The reported wind was 360o at 22 kt. The aircraft landed without obtaining landing clearance from the ATC.
The aircraft was on the centreline until it veered off left approximately 200 feet to the end of the runway, exited the paved surface and came to a stop 978 feet from the end of the runway approximately 33 feet left of the extended centreline.
The aircraft was substantially damaged. All persons onboard were evacuated unhurt.
The accident occurred at night in Instrument Meteorological Condition (IMC).
The accident was caused by an underestimation of the degradation of weather conditions (heavy rain, visibility and strong wind on short final and landing) and the failure by the crew to initiate a missed approach which was not consistent with the company’s SOP.
Other contributing factors to this accident were:
- Non-compliance to company’s SOP in meeting crew competency and complement requirements.
- Ineffective two-way communication between the ATC and DAN0363 during final approach prevented the flow of technical information on runway surface condition and other relevant meteorological information essential to safety.
- Failure of the crew to crosscheck the prevailing wind and also to obtain landing clearance from the ATC during final approach after contact with ATC was restored.
Nine Safety Recommendations were made.
