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.

After landing, the pilot turned the airplane around and back taxied towards the ramp. As he exited the runway, the left landing gear collapsed. Postaccident inspection revealed that the left landing gear bellcrank assembly sustained a stress overload, causing the assembly to break and shear both assembly bolts. The gear retract arm was also found broken. When the gear collapsed, the left wing and left horizontal stabilizer struck the ground and were substantially damaged.
NTSB Probable Cause
Stress overload failure of the bellcrank assembly of the left landing gear.
Full Narrative
On May 1, 1998, approximately 0900 mountain daylight time, a Cessna 320D, N3316Q, operated by Star West Industries, Inc., was substantially damaged while taxiing after landing at Greybull, Wyoming. The airline transport rated pilot and his four passengers were not injured. Visual meteorological conditions prevailed for the air taxi flight being conducted under Title 14 CFR Part 135, and an IFR flight had been filed. The flight originated at Evanston, Wyoming approximately 0745. After landing on runway 33 at South Bighorn County Airport, the pilot turned the airplane around and back taxied towards the ramp. As he exited the runway, the left landing gear collapsed. Postaccident inspection of the landing gear performed by an FAA inspector revealed that the left landing gear bellcrank assembly sustained a stress overload, causing the assembly to break and shear both assembly bolts. The gear retract arm was also found broken. When the gear collapsed, the left wing and left horizontal stabilizer struck the ground and were substantially damaged.
