Wreckage of Dana Flight 922 Crash
Wreckage of Dana Flight 922 Crash

The failure of the pilot in command to take a strategic decision to return to base when the first engine of the ill-fated Dana Air Flight 992 failed 17 minutes into the flight led to its crash.

The aircraft with registration number, 5N-RAM, crashed on June 3, 2012, killing 163 souls on board and on ground.‎

This was disclosed by the Commissioner of Accident Investigation Bureau (AIB), Akin Olateru, who indicted the Nigerian Civil Aviation Authority (NCAA) which is accused of laxity and poor regulation, which enabled a pilot who was not instrumented on an aircraft to operate it.

Olateru who addressed journalists on the detailed report of the Dana Air flight crash, OAS and two Bristow helicopter accidents yesterday in Lagos said that report on Dana crash showed that  the MD 83 aircraft first engine  lost  power  17 minutes  into  the  flight.

He said on  final  approach to landing in lagos the second engine  lost  power  and  failed  to  respond  to  throttle movement  on  demand  for  increased  power  to  sustain  the  aircraft  in  its  flight configuration.

According to the report, the  inappropriate  omission  of  the  use  of  the  Checklist,  and  the  crew’s  inability to  appreciate  the  severity  of  the  power-related  problem,   their  subsequent failure to land at the nearest suitable airfield, lack  of  situation  awareness,  inappropriate  decision  making,  and  poor airmanship were identified as major causes of the accident.

Four  safety   recommendations were  made to   to  Federal Aviation Administration (FAA)  targeting  Pratt  and Whitney  the  engine manufacturer, Dana  Air and  to Nigerian Airspace Management Agency, (NAMA) on Quality Assurance Management.

Olateru said the  flight  originated  from  Abuja  (ABV)  and  the  destination was Lagos (LOS). AIB  published  a  preliminary  report  on  5th  September,  2012  and  four  interim statements have been published. Four  Interim  safety  recommendations  were  made  and  have  been  implemented  by the operator and the regulatory authority.

On AOS helicopter, the Accident  Investigation  Bureau  identified causes to be non-adherence  of  the  Pilot  to  Visual  Flight  Rules  of  clear-of  cloud  and  obstacles while  maintaining  ground  contact  at  all  times  led  to  Controlled  Flight  into  Terrain (CFIT).

In addition to this, the report showed that the pilot was not Instrument Rated and lacked route familiarization.

Five safety recommendations have been made, three  of  which  were  targeted  at  NCAA; one    to  NAMA;  and   one to Nigerian Police Force.

On the Presidential Committee Implementation On  Maritime  Safety  and  Security (PICOMSS), the report showed that the decision  of  the  crew to  continue  the  glide  approach  despite  repeated  landing gear  warnings  with  the  power  lever  below  25 per cent   rather  than  initiating  a  go-around was the cause of the accident.

AIB said contributory  factors to the accident include the failure  of  the  crew  to  recognize  the  landing  gear  warnings, no Standard Operating Procedure/Training Policy in place, the  crew  low  hours  and  experience,  coupled  with  the  rostering  of  two  pilots with same capability on a training flight, Lack of Crew Resource Management (CRM) training.

Two safety recommendations were made to NCAA and  to the Nigerian Police Force.

On Bristow Helicopters, AIB said the causes were identified as 115v  cable  loom  chafed  and  arced  with  hydraulic  pipeline,  puncturing  it  and  causing a  high  pressure  leak  which  ignited  on  contact  with  hot  surface  of  the  right  hand heat exchanger, resulting in fire on the Upper Deck.

Contributory factors  include effectivity  of  the  aircraft  excluded  in  the  Alert  Service  Bulletin  ASB No. 92-20-002A issued by the manufacturer and the  Technical  Directive  TD-S92A-29-99  did  not  include  Check/Inspection  of the right hand side of the Upper Deck.

Two safety recommendations made  in  the  published report and targeted Bristow Helicopters.

Dana Reacts to AIB Accident Report

Nigeria’s domestic carrier, Dana Air has reacted to the report of Accident Investigation Bureau (AIB), which attributed the crash of its Flight 992 on June 3, 2012 in Lagos to human error on the part of the pilot and laxity of the regulatory authority, the Nigerian Civil Aviation Authority (NCAA).

The airline said since the accident it has continued to adhere strictly to safety operation and recommendations of the regulatory body.

“Following the release of the final report of the June 3, 2012 accident, we we wish to reassure our guests of our total commitment to their safety and comfort onboard our flights.

“We wish to also state that Dana Air swung into action immediately the Interim Safety Recommendations were released in 2013 and as an airline strictly committed to the safety and comfort of its guests, we implemented all the recommendations same year, as released by  AIB. We did not stop at just implementing the recommendations; we also successfully passed an operational audit conducted by the Nigerian Civil Aviation Authority’s Flight Safety Group and its foreign partners”, the airline said.

The airline said in 2016, after another rigorous operational audit, Dana Air was admitted into the IOSA register to underscore its strict adherence to global management and safety standards and procedures required of global carriers.

“Also went further to win two awards from two reputable organizations for the redefining role it played in the aviation industry same year,” the airline also said.

It noted that while it acknowledged the full report, and will continue to review it, the airline said it was glad that the report confirmed that the aircraft was airworthy at the time of departure, flight crew were certified and that the airline had cleared all defects during their last check.

“Dana Air maintains a rich spare parts store to date and we have doubled our maintenance and safety efforts with constant training and retraining of our crew and ground staff. This has led to our continuous provision of reliable air transport operation and a record 4.5 million passengers flown in the last 8 years of our operation,” the airline.

“The safety and comfort of our guests remains a top priority to us and maythe beautiful souls of the crew and guests we lost at the unfortunate accident continue to rest in peace- Amen.  They remain forever in our hearts and our prayers and thoughts will continue to be with their friends and loved ones.,” the airline also added.
