Probable cause
INFLIGHT FAILURE OF THE LEFT ENGINE WHICH WAS CAUSED BY INADEQUATE MAINTENANCE AND INSPECTION BY COMPANY MAINTENANCE PERSONNEL RESULTING IN HEAT DAMAGED MAGNETO LEADS AS A RESULT OF A MISSING EXHAUST FLANGE-TO-TURBOCHARGER SEAL. IN ADDITION, THE INFLIGHT POWER LOSS OF THE RIGHT ENGINE WAS CAUSED BY THE PILOT'S FAILURE TO FOLLOW THE PROCEDURES IN THE AIRPLANE OPERATING HANDBOOK AND LAND AS SOON AS POSSIBLE RESULTING IN FUEL STARVATION OF THE RIGHT ENGINE. DARKNESS WAS A RELATED FACTOR.
