Investigation of the black box of the crashed Associated Airline aircraft has revealed that there was a disagreement between the Captain and the First Officer on board before the plane crashed.
According to the readout of the black box ,also known as Cockpit Voice Recorder, CVR, conducted by Nigeria’s Accident Investigation Bureau, AIB, in its Abuja’s laboratory revealed that the computer onboard the plane sent a warning message to the Captain, Yakubu Abdulrahman, shortly before take-off but he ignored it.The First Officer then suggested to the pilot to abort take-off but Yakubu Abdulrahman proceeded and took off.
PRELIMINARY REPORT ON ACCIDENT INVOLVING ASSOCIATED AIRLINE EMBRAER 120 AIRCRAFT REGISTERED 5N reads in part:
“The crew discussed some concerns about the aircraft prior to departure but at this time we are not prepared to elaborate on those concerns as there remains a lot of work to do to complete on the CVR analysis in order to determine the specific nature of the crew’s concerns,” said AIB Commissioner, Muktar Usman.
Usman said approximately four seconds after engine power was advanced to commence the take-off roll, the crew received an automated warning from the onboard computer voice which consisted of three chimes followed by “take-off flaps…take-off flaps.
“This is a configuration warning that suggests that the flaps were not in correct position for take-off. And there is some evidence that the crew may have chosen not to use the flap for take-off,” Usman said.
“This warning continued throughout the take-off roll,” Usman added.
