Abuja, Feb. 12, 2024 – The Nigerian Safety Investigation Bureau (NSIB) says is offering its full cooperation to the National Transportation Safety Board (NTSB) of the United States in the investigation of the tragic Airbus Helicopter EC130B4 crash that killed Herbert Wigwe and five others.
It said it was compelled to collaborate with the US body as a state with a special interest in the accident involving its citizens.
In a statement on Monday, the NSIB Director-General, Captain Alex Badeh, said he had established contact with NTSB in accordance with Chapter 5, Subsection 27 of ICAO’s Annex 13 to the Convention on International Civil Aviation – Aircraft Accident and Incident Investigation, which grants a State (nation) special interest in an accident involving its citizens.
Badeh said state that had a special interest in an accident by virtue of fatalities or serious injuries to its citizens shall be entitled to appoint an expert who shall be entitled to visit the scene of the accident, have access to the relevant information which is approved for public release by the State conducting the investigation, and information on the progress of the investigation.
He said Nigeria could also receive a copy of the Final Report.
Badeh said: “ICAO’s Annex 13 to the Convention on International Civil therefore grants Nigeria, through the Nigerian Safety Investigation Bureau, the prerogative to appoint an expert to actively participate in the investigation.
“This participation ensures access to relevant information and facilitates cooperation with the investigating authorities, towards ensuring the investigation reaches a conclusive outcome.
“The ongoing discussion between the NSIB and NTSB has highlighted the diligent investigation efforts of the NTSB. NTSB investigators were present at the crash scene in Halloran Springs, California, on Saturday to collect evidence and conduct initial on-scene documentation.
“The documentation process included aerial mapping of the wreckage with a drone, and site measurements.
“Correspondence between the NSIB and NTSB further revealed that the NTSB investigation into the crash is being led by Aaron Sauer as the investigator in charge, supported by Mark Ward as the deputy investigator in charge.”
He said several other NTSB investigators would also be examining various aspects of the accident including airworthiness and maintenance structures, operations, meteorology, and air traffic control.
Notably, the airworthiness investigation group, he said has initiated a meticulous examination of the debris field, which spans approximately 100 yards.
He added: “All significant components of the helicopter, including the main transmission, engine, and various avionic elements, were identified and accounted for at the accident site.
“In tandem, the operations investigation group has commenced gathering crucial company information, including pilot records, flight dispatch records, and aircraft maintenance records.
“Moving forward, coordination is underway by the NTSB to transfer the wreckage to a secure location on Tuesday for in-depth examination and analysis scheduled
“Parties to the investigation include Orbic Air, LLC, and the FAA. As the investigation continues, other parties could be named. Additionally, the Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), the French aviation accident investigation agency, will also serve as an accredited representative, due to France being the state of manufacturer the Airbus helicopter and Turbomeca Engine. “Both Airbus Helicopters and Turbomeca Engines will serve as technical advisors to the investigation.”
Badeh said the duration of the accident investigation being conducted by NTSB is expected to take approximately 18 to 24 months to complete.
” The actual duration depends on many factors. Each investigator carries a caseload of many accident investigations which they work on concurrently and each investigation presents its unique complexities.
“The NTSB accident investigation process typically comprises three major milestones. The first is the preliminary investigation report, which contains information gathered by investigators during the on-scene examination.
“This report is expected to be released within 14 to 21 days following the date of the examinations. The next milestone involves the compilation of the public docket, which includes a collection of information gathered throughout the investigation. This typically includes photographs, interview summaries, documentation, and other relevant data.
“Finally, the third milestone is the publication of the final aviation accident report, which serves to conclude the investigation. This report may take up to two years to complete and usually contains analysis and a statement of the probable cause of the accident if determined.
“The Nigerian Safety Investigation Bureau reaffirms its commitment to collaborate fully with the National Transportation Safety Board, aiming for a thorough and conclusive investigation that will enhance transport safety in both Nigeria and the United States.
“The Airbus Helicopter EC130B4 crash has brought a colossal loss to our dear nation Nigeria. Our hearts go out to the Wigwe and Ogunbanjo families and loved ones affected by this tragedy. We extend our deepest sympathies to them during this difficult time. Updates on the investigation will be provided as information becomes available.” (GBN)
