THE PILOT SAID THAT WHILE ON FINAL APPROACH, HE EXPERIENCED A SINK RATE WHICH HE WAS UNABLE TO ARREST BEFORE THE AIRPLANE COLLIDED WITH THE TERRAIN SHORT OF THE RUNWAY THRESHOLD. HE SAID HE DID NOT EXPERIENCE ANY MECHANICAL PROBLEMS AND THE WIND WAS CALM. ## Factual narrative On October 19, 1994, at 0940 hours Pacific daylight time, a Stan G. Hallam homebuilt RV-6 airplane, N93SJ, crashed north of runway 16 at Bryant Field, Bridgeport, California. The pilot was completing a visual flight rules personal flight. The airplane, registered to and operated by the pilot, sustained substantial damage. The certificated private pilot, the sole occupant, did not receive any injuries. Visual meteorological conditions prevailed. The flight originated at Madera Airport, Madera, California, at 0840 hours. The pilot said in the aircraft accident report that while on final approach the airplane experience a heavy sink rate. He was unable to arrest the sink rate before colliding with the terrain north of the runway threshold.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB LAX97LA314](https://openairdocs.org/ntsb/LAX97LA314), Sep 6, 1997: Hallam RV-6 (N93SJ), Woodlake, CA, substantial damage. Probable cause: failure of the pilot to accurately determine the quantity of fuel onboard the airplane before flight, and subsequent loss of engine power due to fuel starvation, which resulted in a forced landing. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
