## Analysis

HIGH SINK RATE DEVELOPED ON SHORT FINAL. ACFT TOUCHED DOWN 13 FT PRIOR TO RUNWAY BEFORE SINK RATE COULD BE ARRESTED. LANDING GEAR COLLAPSED AFTER CONTACTING EDGE OF RWY WHICH IS 7 INCHES HIGHER THAN SURROUNDING TERRAIN. TAIL SECTION OF ACFT CAUGHT FIRE JUST PRIOR TO COMING TO A COMPLETE STOP 2900 FT DOWN THE RWY. PILOTS WHO FREQUENTLY FLY IN AND OUT OF THE ARPT STATED, WIND SHIFTS NEAR THE RWY ARE COMMON IN GUSTY CONDITIONS BECAUSE OF HILLY TERRAIN.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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. Compare the reported make and model.
