NTSB narrative

While flying at night, about 10,000 feet msl, the flight reported an engine problem, declared an emergency, and requested vectors to the nearest airport for landing. When queried, the pilot stated, '...we got a fire in the right engine.' While diverting, the pilot was unable to maintain altitude (level flight) until the airplane descended to about 1700 feet. The tops of ridges in the area were about 2500 to 2800 feet. Subsequently, about 15 miles from the alternate airport, the airplane hit trees during darkness at an elevation of about 1720 feet and crashed. Examination of the right engine revealed that the last 8 to 12 inches of the right overboard tube had separated circumferentially from the exhaust system. A metallurgical examination of the exhaust stack revealed evidence of fatigue; there were numerous hot gas corrosion cracks that had originated at the interior surface and had propagated through the wall thickness of the stack. There was evidence that a breach of the right exhaust stack allowed hot, high velocity gases to escape and initiate a fire. The Altoon weather was in part: 8,000' scattered, 3 miles visibility with fog and haze.

Probable cause

propagation of corrosion cracks in the right engine overboard exhaust stack and fatigue failure of the exhaust stack, which resulted in escape of hot/high velocity gases, in-flight fire, emergency descent, and subsequent collision with trees during an approach for a forced landing. Darkness and mountainous/hilly terrain were related factors.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
