The Embraer-120 aircraft, with registration number 5N-BJY, was operated by Associated Airlines and was on a private charter flight from Lagos to Akure.
It crashed shortly after take-off at the local wing of the Murtala Mohammed Airport, Lagos.
The aircraft was said to have been carrying 20 persons, including the crew as well as the remains of the former governor of Ondo State, Dr Olusegun Agagu.
Oketunbi said; “AIB will analyse the black box at its newly constructed accident investigation bureau office in Abuja.
“However, if we encounter any challenges while doing that, we may contact our foreign partners for assistance,” he said.
The black box usually contains the conversation between pilots and control tower at the airport prior to any accident.
The black boxes of previous crashes were sent abroad for analyses, and delayed the release of the bureau’s reports on its findings. (NAN)
