Accident Summary
An aircraft crashed at the 2,800-foot level of Twin Mountain on a heading of 120 degrees at 2035 hours local time, after executing a missed approach at Whitefield during instrument meteorological conditions (IMC). The aircraft was last seen by ground observers at approximately 2015 hours, heading toward the airport at an altitude of 300 to 400 feet above ground level. The only indication of trouble was the low altitude of flight.
Four occupants were killed, and one passenger was seriously injured.
Investigation Findings
No fuel was found in the engine fuel dividers or fuel lines. The inboard fuel tanks were more than half full, while the outboard tanks' fuel state was not specified. Normal operation calls for takeoff, climb, and descent using the inboard tanks; outboard tanks are used for non-maneuvering cruise flight.
Weather conditions were reported as low ceiling. The aircraft was executing a missed approach under IFR before the loss of power.

1. Fluid, fuel – starvation 2. In-flight planning/decision – improper – pilot in command 3. IFR procedure – improper – pilot in command 4. Fuel tank selector position – improper – pilot in command
- Occurrence #2: Forced landing
- Phase of operation: Descent – emergency
- Findings:
5. Weather condition – low ceiling
- Occurrence #3: In-flight collision with terrain/water
- Phase of operation: Landing – flare/touchdown
