What happened
On August 19, 1986, at approximately 1500 Alaska Daylight Time, a pilot departed from an undisclosed location with the intention of flying to Hoonah, Alaska. The flight proceeded without incident initially, but the aircraft failed to arrive at its destination or return as expected. Consequently, search and rescue operations were initiated by authorities.
The wreckage was located the following day, August 20, at approximately 1400 ADT. The aircraft had crashed into rising mountainous terrain at an elevation of about 1,740 feet. Examination of the site indicated that the aircraft impacted in a steep nose-down attitude. There was virtually no movement of the wreckage after the initial impact.
The investigation
A physical examination of the aircraft revealed specific damage patterns consistent with the crash dynamics. The wings exhibited a slight counter-clockwise twist, and both the floats and the tail cone were canted to the left side of the fuselage. These structural deformations provided insight into the orientation and forces involved during the collision with the terrain.
Findings
Post-impact analysis included toxicological testing of the pilot. A check of the pilot's blood showed a slight amount of alcohol, measured at 0.026%. However, investigators noted that this amount could not be verified as pre-flight consumption due to possible putrefaction of the body after death. No other mechanical failures or environmental factors were explicitly cited in the provided narrative.
Safety message
The incident highlights the risks associated with flying in mountainous terrain where search and rescue efforts may be delayed by weather or geography. Pilots are reminded to ensure reliable communication and adherence to flight plans to facilitate timely assistance if an emergency occurs.
