NTSB narrative

The single-engine airplane was established at a cruising altitude of 12,000 feet MSL. The instrument rated commercial pilot requested a descent to a lower altitude and was given clearance to descend to 10,000 feet by ATC. After the pilot acknowledged the clearance, radar contact and voice communications from the aircraft were lost. No distress calls were received from the aircraft. The wreckage of the airplane, which had impacted the ground in a near vertical attitude, was found by a search and rescue helicopter in an open field. Several aural witnesses, located near the accident site, reported hearing a very loud engine noise followed by silence. Several residents in the vicinity reported the local weather to be foggy, with freezing rain, and low clouds. The aircraft, which was not equipped for flight in icing conditions, was operating within the boundaries of a current weather advisory, which called for rime icing in the clouds below 8,000 feet. No mechanical anomalies were found during examination of the wreckage. Pilots flying various types of aircraft in the vicinity of the accident site had reported light to moderate icing in the clouds from 16,000 feet to 4,000 feet. According to the NTSB meteorologist, it was likely that the pilot could have encountered IMC conditions with light to moderate icing.

Probable cause

the loss of control during cruise flight for undetermined reasons.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
