There was a malfunction of the electronic engine control (EEC) burner pressure (Pb) sensor that had an abnormally high indication that resulted in an excessive amount of fuel being pumped into the engine that was still at a sub-idle condition. Because the engine was still accelerating to idle, the limited airflow through the engine engine was insufficient for the amount of fuel and resulted in a tailpipe fire. The cause of the EEC's Pb sensor fault could not be determined.

the inadequate crew/group coordination and the parking brakes not set by the pilot in command.
