AIB Releases Final Report On PICOMSS, Dana, Bristow, OAS Air Crashes

AIB Releases Final Report On PICOMSS, Dana, Bristow, OAS Air Crashes

The Accident Investigation Bureau (AIB) yesterday released the final report of the accidents involving Dana Airlines, Bristow Helicopters, OAS Helicopters (Nig) Limited and the Presidential Implementation Committee on Maritime Safety and Security (PICOMSS).

The reports were revealed by the Commissioner of the Accident Investigation Bureau, AIB, Engr Akin Olateru at the agency’s headquarters at Murtala Muhammed International Airport Ikeja, Lagos.

Unearthing the possible issues on the accident involving Dana Airlines, Boeing MD-83 Aircraft with registration 5N-RAM on 3rd  June  2012 at Iju-Ishaga, Lagos State,  at  about 1545:00hrs, Engr Olateru stated that the possible causal factors includes: “engine  number  1  lost  power  seventeen  minutes  into  the  flight,  and  thereafter on  final  approach,  engine  number  2  lost  power  and  failed  to  respond  to  throttle movement  on  demand  for  increased  power  to  sustain  the  aircraft  in  its  flight configuration”.

Other possible causal factors as identified by the AIB include “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 and lack  of  situation  awareness,  inappropriate  decision  making,  and  poor airmanship”.

On OAS Helicopters accident involving Ecuruiel A350B2 Helicopter with Registration 5N-BKA at Oke-Oba Hill, Ikonifin, Osun State on 29th July, 2011, the AIB boss stated that “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) are the major causal factor.

On the serious incident that involved Presidential Implementation Committee on Maritime Safety and Security (PICOMSS) with registration 5N-BKA at Benin Airport, Edo State on 5th July, 2012, the aviation agency stated that the casual factor has to do with “the decision  of  the  crew  to  continue  the  glide  approach  despite  repeated  landing gear  warnings  with  the  power  lever  below  25%  rather  than  initiating  a  Go-around” .

Contributory factor to the PICOMSS incident, according to AIB, 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 and lack  of  Crew  Resource  Management  (CRM)  training.

On the incident involving Bristow Sikorsky S-92 with registration 5N-BKA at MMA Lagos, on 27th February,  2013, AIB attributed the ugly incident to the fact that “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”.

It added other contributing factors to the Bristow’s incident, stressing that “the  affectivity  of  the  aircraft  was  excluded  in  the  Alert  Service  Bulletin  ASB No.  92-20-002A  issued  by  the  manufacturer; and that the  Technical  Directive  TD-S92A-29-99  did  not  include  Check/Inspection  of the  right  hand  side  of  the  Upper  Deck”.

AIB further gave recommendations on each of incidents. In the case of Dana Air, eight safety recommendations were made to forestall future occurrences.

The  safety  recommendations  previously  made  in  the  Preliminary  Report published  on  5th  September  2012  were four  in  number, wherein  three were targeted  to  Dana  Airlines  and  all  were  accepted  and  closed.  One was to NCAA, accepted and closed.

However, Bristow  Helicopters  Nigeria  Limited  issued  a  Technical  Directive,  TD-S92A-29-104 following  the  incident with the subject: “Inspect  LH  and  RH  MGB,  and  Upper  Deck  Heat  Exchanger  Area,  All  1, 2,  and  3  system  Hydraulic  lines,  Clamping  all  Components,  and  wiring Looms  for  any  damage,  chafing,  or  wear”.

In his closing remarks, Engr Olateru who pointed out the cost of investigating an accident or serious incident is very huge, advised stakeholders to come up with a seminar that will involve the entire members to discuss these issues.

Meanwhile, Dana Air has reassured its numerous passengers that the airline is fully committed to safety and comfort at all times.

Following the release of the final report of the June 3, 2012 Accident, Dana Airline in an official statement issued yesterday and signed by the Media/Communications Manager, Kingsley Ezenwa stated: “We wish to reassure our guests of our total commitment to their safety and comfort onboard our flights” .
