Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE CFI WAS DEMONSTRATING A PINNACLE APPROACH TO A LANDING ON A MOUNTAIN TOP. THE CFI DID NOT PERFORM A HIGH RECONNAISSANCE FLIGHT BEFORE BEGINNING THE APPROACH. DURING THE APPROACH, THE FLIGHT ENCOUNTERED A TAILWIND AND THE CFI APPLIED FULL POWER, BUT WITHOUT SUCCESS. THE HELICOPTER'S DESCENT RATE INCREASED RESULTING IN A HARD LANDING. THE SURFACE WINDS TURNED THE HELICOPTER RENDERING IT UNCONTROLLABLE AND IT SLID DOWN THE SIDE OF THE MOUNTAIN.
NTSB Probable Cause
the CFI's poor inflight planning/decision and failure to follow normal procedures. The tailwind was a factor in this accident.
Full Narrative
On October 18, 1993, at 1430 Pacific daylight time, a Robinson R-22 Beta, N192KC, landed short of a mountain top while demonstrating a mountain top landing at Mount Haines, Angeles National Forest, about 10 miles north of Sunland, California. The pilots were conducting a local visual flight rules instructional flight. The helicopter, operated by Complete Aviation Services, Burbank, California, sustained substantial damage. The certificated airline transport pilot/certified flight instructor and the non-certificated student pilot received minor injuries. The flight originated at Burbank Airport, Burbank, California, at about 1230 hours. The pilot stated that during the approach to the mountain top he encountered a wind shear condition which caused him to land short of the mountain top. After landing, the helicopter rolled over.
