The black box of the Associated
Airline aircraft which crashed on
Oct. 3 in Lagos Nigeria has
revealed that, there appeared to
have been an argument between
the Captain and the First Officer of
the Airline.
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.
