- USFS: Probable Cause
The most probable cause of this mishap was determined to be the pilot’s acute in-flight incapacitation due to sleep.
- Note: Prior to 1996 NTSB did not investigate Gov owned and operated, Gov owned and contractor operated or some aircraft that were privately owned and operated as "public aircraft". Government agency investigations and reports were/are often hard to find and access. The "Pressler Act", passed in 1995 and enacted in 1996, changed that, making all aircraft accident reports easier to access and lessons easier to learn. (Click the link and search on "Pressler".)
