NTSB narrative
The pilot stated that during the landing gear retraction he heard a loud bang, followed by three to four smaller bangs. The first officer confirmed that the left engine was the affected engine and immediately began feathering the propeller. Once the propeller had been feathered, the captain confirmed the action by looking outside and noticing the propeller in the feathered position. The captain further reported that the right engine was producing the maximum power available and was indicating 55 inches of manifold pressure. Unable to achieve airspeed of greater than 95 to 96 knots indicated, the captain attempted to return to the airport for an emergency landing; however, he was unable to maintain altitude and attempted to land on an airport perimeter road, impacting the airport fence and a sand berm in the process. A cursory examination of the engine and system components revealed no evidence of a preimpact mechanical malfunction.
Probable cause
A total loss of left engine power and subsequent failure of the airplane to maintain airspeed and altitude on the remaining engine for undetermined reasons.

- 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, coordinates. 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.
