During the starting sequence of the aircraft’s engine No.4 (P&W PW4056), the Engine-Indicating & Crew-Alerting System (EICAS) generated the following message, "ENG 4 FUEL VLV." The message came on and then went off after several seconds. The message disappeared and all of the number 4 engine’s parameters were normal. The crew opted to continue the flight. While advancing the throttle levers ~ 64 degrees with the aircraft reaching a ground speed of ~59 knots (Kts), the No.4 engine reached a maximum of 1.1 EPR (Engine Pressure Ratio), approximately 0.2 EPR less than the other engines. During the takeoff roll, three faults for the engine were recorded. The EICAS displayed the following messages, "ENG 4 CONTROL", "ENG 4 FUEL VLV," followed by a number 4 engine N2 Redline Exceedance accompanied by a loud rumbling noise. The crew aborted take-off and the aircraft returned to the gate. During the engine fault troubleshooting processes, the engine experienced an engine tailpipe fire.
The investigation concluded that contaminated fuel affected the operation of servo driven components resulting in the N2 Redline event. The fuel samples from the 9M-MPM did not meet acceptable quality standards. The Aircraft 9M-MPM had a history of number 4 engine of faults that were likely not properly addressed during previous maintenance actions. The investigation identified a number of safety issues associated with the aircraft maintenance and the CAA oversight along with the fuel storage facilities at WMKK.
