Report Reveals the Causes of Bristow Helicopter Crash In Oworonshoki

The primary report explained that the “National Emergency Management Agency (NEMA) led the rescue with Lagos State Emergency Management Agency (LASEMA) and Lagos State Waterways Authority
(LASWA) playing an important role” in coordinating and responding to the crash.It added that Julius Berger Ltd. “placed a vital role in wreckage recovery.”

Also found was that “neither the crew nor the passengers had the opportunity to either inflate their life jackets or deploy the raft.” It also found that the crew did not make a distress call before the helicopter crashed into the lagoon though the report did note that “there was good communication between the helicopter and the Tower before the accident.”

The Cockpit Voice Recorder was also installed on the helicopter. The recorders were recovered by professional divers in good condition from the lagoon on the second day of the accident, but the combined recorder had few punctures. The recorders were sent to Air Accident Investigation Branch UK for data download.

The report stated that the Accident Investigation Bureau “discovered that the Forward Main Servo Input Control Pushrod Assembly had failed. The Control Pushrod tube separated from Control rod end with the bearing and the Jam nut. The Jamnut was loose and was not seating against the Control Rod.” This, as inferred from the report, could have been at least one cause of the accident.
