NAF 931’S FINAL HOURS: ENGINE FAULT REPORTED BEFORE AIRCRAFT LEFT BENIN FOR LAGOS

The Nigerian Air Force aircraft that crashed in Ondo State on Monday reportedly developed an engine fault a day earlier and was grounded overnight in Benin City for repairs before being cleared to fly to Lagos, ValidViewNetwork reports.

The development raises fresh questions about the aircraft’s mechanical condition in the hours before the fatal flight and whether the reported fault was fully resolved before the aircraft returned to service.

According to an exclusive report obtained by ValidViewNetwork, the ATR-42 aircraft, identified as NAF 931, developed the engine problem on Sunday, October 4, while in Benin. It was subsequently grounded overnight for maintenance work before departing Benin for Lagos on Monday morning.

ValidViewNetwork understands that the reported maintenance episode will now be a significant point of interest in any investigation into the crash, although there is currently no official finding that an engine fault caused the aircraft to go down.

AIRCRAFT LOST CONTACT AFTER TAKE-OFF

NAF 931 was operating a routine flight from Benin to Lagos when it crashed in a swampy area near the Naval Base in Igbokoda, Ilaje Local Government Area of Ondo State.

Air traffic controllers reportedly lost contact with the aircraft at about 9:13 a.m., shortly after take-off. Search teams later located the wreckage in difficult swamp terrain, where recovery operations have been severely hampered by water, mud and mangrove vegetation.

The Nigerian Air Force subsequently confirmed that 25 people, comprising five crew members and 20 passengers, were on board.

ENGINE FAULT CLAIM NOW UNDER SCRUTINY

ValidViewNetwork reports that the reported engine problem is now one of the key issues that investigators will need to establish independently.

Among the questions requiring answers are what fault was detected on Sunday, what repairs were carried out, which personnel worked on the aircraft, what checks were conducted after the repairs and who authorised NAF 931 to undertake the Benin-Lagos flight.

The report of the earlier engine problem does not, by itself, establish a connection between the maintenance episode and the crash.

Ondo State Governor Lucky Aiyedatiwa had earlier suggested that a technical or mechanical problem could have contributed to the aircraft losing communication, but the governor did not present that possibility as an established finding.

WHAT THE INVESTIGATION MUST ESTABLISH

ValidViewNetwork can confirm that the reported pre-crash maintenance history makes the aircraft’s technical records particularly important to the investigation.

Investigators will need to examine the aircraft’s maintenance logbooks, defect reports, repair records, technical release documents and other relevant records to determine whether the reported engine fault was properly diagnosed and rectified.

They will also need to establish whether the aircraft underwent the required inspections before departure and whether any warning signs remained after the reported repairs.

The aircraft’s flight data, cockpit recordings, air traffic communications and wreckage examination will also be important in determining what happened during the final stages of the flight.

RECOVERY OPERATION CONTINUES

Meanwhile, recovery teams continue to battle the swampy terrain where the aircraft went down. The wreckage is partly submerged, making access difficult and slowing the evacuation of victims. Security personnel have also restricted access to the crash site as recovery and investigation operations continue.

ValidViewNetwork gathered that the difficult terrain has added another layer of complexity to the investigation, particularly as investigators will need to preserve and recover critical aircraft components and, where possible, flight-recording equipment.

ValidViewNetwork reports that the alleged engine fault the day before the crash is a significant new line of inquiry, but it must be treated as a reported development until supported by the aircraft’s maintenance records and the official investigation.

The central question is not simply whether NAF 931 experienced a mechanical problem before the flight, but whether that problem was correctly diagnosed, adequately repaired and properly cleared before the aircraft was allowed to depart Benin.

The final investigation should therefore establish the aircraft’s technical condition, the maintenance work carried out before the flight and the precise sequence of events that led to the crash. Only a transparent, evidence-based process can determine whether the reported engine fault had any connection to the tragedy.
