The Nigerian Safety Investigation Bureau (NSIB) has detailed the extensive damage to an Arik Air aircraft that occurred during the climb out en route to Port Harcourt International Airport, Port Harcourt, on February 11, 2026, in its preliminary report.

On 11 February 2026, a Boeing 737-700 aircraft with nationality and registration marks 5N-MJF, operated by Arik Air Limited, was on a scheduled passenger flight from Murtala Muhammed International Airport (DNMM), Lagos, to Obafemi Jeremiah Awolowo International Airport (DNPO), Port Harcourt.

On February 11, 2026, a B737-700 aircraft with nationality and registration 5N-MJF operated by Arik Air Limited was on a scheduled passenger flight from Murtala Muhammed Airport, Lagos to Port-Harcourt. The report details a significant mid air engine failure that forced the flight, which was en route from Lagos to Port Harcourt with 80 passengers and 7 crew members, to divert to Benin Airport.

The report highlights that the incident, which occurred at an altitude of approximately 26,000 feet while en route from Lagos to Port Harcourt, resulted in at least 23 separate wreckage impacts on the aircraft. It is also based on factual information from the flight crew, air traffic control transcripts, and flight data recorders (FDR/CVR).

All other 23 fan blades were found to be chipped or damaged. The engine inlet cowling was missing entirely. One fan blade (number 6) was broken off at the root, while the remaining 23 fan blades were all found to be chipped or damaged. The inboard and out- board engine cowling covers were folded upward, exposing internal engine accessories.

According to the report, an engine driven pump (EDP) clamp was found loose, and a deep cut of approximately 0.6 inches was noted on the airframe.

The report confirms that the crew heard a “loud bang” followed by abnormal engine indications at cruising altitude, leading to a precautionary engine shutdown and an emergency diversion. All 80 passengers and 7 crew members, according to the accident investigative body, disembarked safely in Benin.
