The investigators said this retraining was in order for the
crew to be able to understand and recognise engine failure/malfunctions and its
effect(s) at every phase of flight before they are allowed to resume flight
duties.
The AIB-N gave this immediate safety recommendation to be
carried out along with seven (7) others issued to Azman Air following a serious
incident on its aircraft, a Boeing 737-500 aircraft with registration marks
5N-AIS which occurred at Port Harcourt, Nigeria on 3rd January, 2019.
The AIB-N made these known today when it released final
reports on three serious incidents including Max Air Limited’s Boeing 747
aircraft from 2019, Nigerian Police Airwing, Cessna Citation 560 XLS aircraft
as well as Azman Air service Limited, Boeing 737-500 which occurred in 2019.
On the Azman Air flight which got Seven (7) Safety
recommendations, and one immediate recommendation directed to the NCAA, the AIB
revealed that the casual factor was a result of failure of number 4 and 5
bearings of engine number 2 leading to loss of power during approach of the
aircraft.
Contributory factors according to the AIB included: failure
to recognise the abnormal engine conditions (surge) during cruise phase and
hence, not making appropriate decision. This might have been connected to the
insufficient technical knowledge and loss of situational awareness.
Other are non implementation of the Flight Data Monitoring
programme in accordance with 2.2.5.1 of Azman Air Safety Management System Manual,
non rectification of the number two engine vibration anomalies recorded over a
period of 8 months, inadequate regulatory oversight of the Azman Air Safety
Management System.
It said no action has been taken on the Immediate Safety
Recommendations.
On the Max Air Incident, seven (7) safety recommendations
were proffered as the AIB explained that the aircraft with registration marks
5N-DBK, Flight NGL2092 departed King Abdul Aziz International Airport, Jeddah;
Kingdom of Saudi Arabia, (OEJN) with returning Hajj pilgrims bound for Minna
Airport, Nigeria, (DNMN).
The aircraft touched down on the right of the centreline of
RWY 05 with the left main wheels first and the number one engine nacelle
impacted the runway and was dragged along the runway centreline.
AIB identified excessive rudder and aileron inputs at short
finals phase of the approach as causal factors while decision to continue the
ILS approach runway 05 with erratic localizer signals and an un-stabilized
approach with a no go-around decision as contributory factors.
On the Cessna Citation 560 XLS+ aircraft with registration
marks 5N-HAR operated by the Nigeria Police (NP) five (5) safety
recommendations were prescribed.
The causal factor for the crash which had six(6)passengers
on board was uncoordinated flight as a result of inadequate Crew Resource
Management (CRM) that led to the partial release of parking brake, which
resulted in rejected take-off while the and contributory factors were the
inability of the aircraft to get airborne after attaining the rotation speed
(Vr)during take-off roll even with aft elevator pressure.
The other was non-adherence to Standard Operating Procedures
(SOPs) as contained in the Cessna Citation 560 XLS+ Airplane Flight Manual.
With the release of these final reports are 20 Safety
Recommendations, addressed to the regulatory body, the Nigerian Civil Aviation
Authority (NCAA), the affected airlines, the Nigerian Airspace Management
Agency (NAMA), an aircraft manufacturer, the Federal Airport Authority of
Nigeria, among others.
