The Accident Investigation Bureau (AIB) said on Monday that it was yet to determine the cause of the crash of the Bristow Helicopters S-76 chopper, which went down into the Lagos Lagoon on August 12.
Six persons, including the pilot and the co-pilot, were killed after the helicopter, which was enroute Lagos from Akure, crashed into the Oworonshoki area of the lagoon.
Felix Abali, AIB’s Commissioner, while presenting the bureau’s preliminary report on the incident, said that preliminary findings revealed that the pushrod assembly of the chopper “became disjointed and could not hold together”.
The failure of the pushrod assembly can result in a loss of main rotor or tail rotor flight control and consequent loss of control of the helicopter.
