Aircraft Accident/Incident Report
Libby, Montana 59923
Sunday, June 6, 1999 9:00 MDT
NTSB Narrative Summary Released at Completion of Accident
The airplane went missing on a flight from the airport where an amphibious float installation had just been performed. Its wreckage was located several hours after departure at the 6,100-foot level on a snow-covered ridge in a National Forest wilderness area, 11 nautical miles from the departure airport. The pilot was found dead at the accident scene. Recovery personnel reported that the airplane appeared to have struck trees and impacted going down a 32-degree slope, where it impacted a tree stump in a depression. The recovery crew also reported that all aircraft components were found within about 20 feet of the main wreckage, that there was no evidence of fire, that search-and-rescue personnel (the first persons to reach the site) had reported a strong fuel smell, and that the airplane had good flight control continuity 'as best as could be determined.' Post-accident examinations of the airplane's engine and fuel injection servo disclosed evidence of non-compliance with various FAA Airworthiness Directives and manufacturer's service bulletins, but no clear evidence of any mechanical anomalies or malfunctions. Visual meteorological conditions were reported at a weather observation station 59 nautical miles away from the site during the accident time frame.
