Maintenance disclosure history
Service Difficulty Reports are self-reported maintenance findings. The NUMBER of reports is not a measure of reliability — diligent operators file more, not fewer. These are shown for transparency, not as a negative signal.
1 report on file.
THE PROBLEM APPEARS TO BE A PLUGGED SCAVENGE LINE DUE TO INTERNAL ENGINE COKING. THE RESULT COULD BE EXCESSIVE INTERNAL OIL PRESSURES CAUSING EXTERNAL DISCHARGE OF THE OIL, IN THIS CASE OUT THROUGH A VENT LINE. ALONG WITH THAT THERE WOULD BE A BYPASS OF OIL INTERNALLY THROUGH THE LABYRINTH SEALS (3) AND WOULD ALLOW THE OIL TO ENTER AND EXIT THE GAS GENERATOR ALLOWING FOR AN IGNITION SOURCE AND IGNITION. AT THAT POINT YOU WOULD HAVE AN IGNITION SOURCE AT THE GAS GENERATOR, BURNING OIL RUNNING DOWN THE SIDE OF THE ENGINE ALONG WITH VENTING OIL AVAILABLE DRAINING ONTO THE DECK AND ADDING FUEL (OIL) TO THE FIRE.
