Pilots Were Arguing Before Agagu’s Plane Crashed

There appeared to be an argument between the Captain and the First
Officer of the Associated Airline aircraft which crashed on 3 October in
Lagos Nigeria and killed 15 people, the aircraft’s black box has revealed.

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.
“The First Officer asked if the take-off should be aborted approximately 12
seconds after the ‘eight knots’ callout,” said Captain Mukhtar Usman,

Commissioner Accident Investigation Bureau,AIB.
AIB said the pilot and the co-pilot discussed some concerns about the
aircraft prior to departure.

“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.

“Approximately three seconds after ‘power is set’ call, the First Officer
noted that the aircraft was moving slowly.
“At this time we can state that the Right engine appeared to be producing
considerably less thrust than the left engine. The left engine appeared to be
working normally,” Usman said.
