The Commissioner/CEO, of the Agency, Engineer Akin Olateru, described this as its biggest haul since the establishment of AIB-N, while commending the Agency’s diligent and resourceful air safety investigators for their sacrifices and focus in delivering on the mandate

The reports:
1. Serious incident involving a B737-500 aircraft operated by Air Peace Limited with nationality and registration marks 5N-BRN, which occurred at Port Harcourt Airport, Omagwa, Rivers State On 22nd June, 2019.

The investigation according to Olateru, identified ‘loss of speed, altitude and situational awareness due to poor instruments’ scanning on short finals Runway 05,’ as the causal factor.

Two contributory factors identified were that; ‘the airplane was flown at a high descent rate (825 fpm) when the aircraft was just 225 ft above runway during approach’ and ‘possible increase in crew workload due to thunderstorm activities in the vicinity of the airport.

The Commissioner explained that in view of the issuance of the Nigeria CAR 2009 and the revision in 2015, which addressed the areas of shortcomings identified in this investigation, no safety recommendations are made.

4. Report on the Serious Incident involving a Bombardier DHC-8-Q400 aircraft owned and operated by Arik Air Nigeria Ltd with nationality and registration marks 5N-BKX which occurred en route Kotoka International Airport, Accra, Ghana on 6th March, 2018

Olateru stated that the incident occurred at dusk in Instrument Meteorological Condition and investigation identified engine oil leaked onto the hot surfaces of the engine No. 2 due to a failed seal which produced fumes that mixed with the bleed air supply to the air conditioning system, resulting in smoke in the aircraft cockpit and cabin, as the causal factor.

No contributory factor was identified and two Safety Recommendations were made; ‘Arik Air Nigeria Limited should ensure that flight crew execute appropriate checklist items completely in line with the aircraft Flight Crew Operating Manual (FCOM) and Quick Reference Handbook (QRH).

‘The Nigeria Civil Aviation Authority (NCAA) should ensure that flight crew type-rated on Bombardier DHC-8-Q400 should undergo further training on ‘The effects of smoke in an enclosed area and actual use of relevant equipment in a simulated smoke environment.’

5. Report on the ‘Serious Incident’ involving a Boeing 737- 500 aircraft operated by Med-View Airline with nationality and registration marks 5N-BQM, which occurred at FL320 en route Murtala Muhammed Airport, Lagos On 23rd July, 2019.

The Commissioner announced ‘Black hole effect disorientation causing low-level manoeuvre into grass verge’ as causal factor.

Two contributory factors were identified as; ‘Most of the Runway 21 right edge lights were unserviceable at landing time’ and ‘Inadequate Crew Resource Management during approach.’

One safety recommendation was given to the Federal Airports Authority of Nigeria (FAAN) to ensure the serviceability of DNPO runway lighting systems during all operations.

7. Report on the Serious Incident involving an Airbus 330-343 aircraft operated by Turkish Airlines Incorporation with nationality and registration marks TC-LOL, which occurred at Port Harcourt Intl. Airport, Omagwa, Rivers State, Nigeria on 31st December 2019.

The Commissioner announced causal factor as ‘The extra right aileron and rudder input by the Pilot Flying in the last 100 feet caused the aircraft to drift right of the runway centreline.

The contributory factors were; ‘The inappropriate rudder application by the flight crew in the last 45 feet did not prevent the right drift before touchdown but rather increased the drift at touchdown.

‘The non-adherence to the provisions of the Standard Operating Procedures as contained in the Turkish Airlines Flight Crew Techniques Manual.’

One Safety Recommendation was made was that Turkish Airlines Incorporation should ensure flight crew adherence to provisions of the Standard Operating Procedures as contained in the Turkish Airlines Flight Crew Techniques Manual vis-à-vis landing techniques.

Olateru appreciated the Minister of Aviation, Senator Hadi Sirika, for his unrelenting support for the Bureau without which it would have been almost impossible to attain all monumental achievements it has recorded in the last few years.
