NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The crew of a tailwheel-equipped airplane landed on a gravel-covered, off-airport site at the completion of a Title 14, Code of Federal Regulations Part 135 cargo flight. The captain said that while taxiing to parking after an uneventful landing, he and the other pilot heard a loud “thump”, and he stopped the airplane. The crew’s inspection revealed that the airplane’s tailwheel had collapsed, and as a result, the fuselage adjacent to the tailwheel sustained substantial damage. A postaccident examination revealed a fractured shock absorber linkage, which was part of the tailwheel swivel assembly.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A fracture of the airplane's tailwheel shock absorber linkage during taxi, resulting in the collapse of the tailwheel.
