## Probable cause

the pilot's inadequate fuel management, and his improper use of the fuel selector valve, which resulted in fuel starvation and the subsequent collision with bails of hay during the forced landing.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - nonmechanical, maneuvering
  - fuel management - inadequate, pilot in command (cause)
  - fuel tank selector position - improper use of, pilot in command (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, emergency descent/landing
- On ground/water encounter with terrain/water, emergency landing
  - terrain condition - loose objects

## Analysis

The pilot reported that the purpose of the flight was for his passenger/neighbor to photograph a farm located approximately 8 miles northwest of Cortland. During the final pass over the farm, about 1100 feet above ground level, there was a total loss of engine power. The pilot performed emergency procedures during which he turned the auxiliary fuel pump on, changed the fuel selector valve from the right tank to the left fuel tank, and used the primer. The engine momentarily started followed by another loss of power. The pilot performed a forced landing in an open field. During the forced landing, the airplane collided with bails of hay. Postaccident examination revealed no mechanical malfunctions.  The left fuel tank was half full, and the right tank had residual fuel.

## Factual narrative

On March 27, 1996, about 1825 eastern standard time, a Grumman American AA-1C, N9974U, was substantially damaged when it collided with bails of hay, during a forced landing, near Groton, New York.  The private pilot and passenger received minor injuries.  The personal flight departed Cortland, New York about 1800 for a local flight.  Visual meteorological conditions prevailed, and there was no flight plan filed for the flight conducted under 14 CFR Part 91.

According to the NTSB Form 6120.1/2, the pilot reported that the purpose of the flight was for his passenger/neighbor to photograph a farm located approximately 8 miles northwest of Cortland.  During the final pass over the farm, about 1100 feet above ground level, there was a total loss of engine power.  The pilot performed emergency procedures during which he turned the auxiliary fuel pump on, changed the fuel selector valve from right to the left fuel tank, and used the primer.  The engine momentarily started followed by a total loss of power.  The pilot performed a forced landing to an open field.  During the forced landing, the airplane collided with bails of hay.  The pilot also indicated in the form that there was a mechanical malfunction.

The Federal Aviation Administration examined the wreckage on March 28.  Post-accident examination revealed no mechanical malfunctions.  The left fuel tank was half full and the right tank had residual fuel.
