NTSB narrative
On December 4, 2024, about 1420 Pacific standard time, a Cessna 150L, N5330Q, sustained substantial damage when it was involved in an accident near Glen Avon, Oregon. The pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that he was on the return leg of a cross-country flight to Bend Municipal Airport (KBDN), Bend, Oregon. About 20 miles into the trip, at an altitude of about 8,000 feet mean sea level (msl), the engine started to run rough. The pilot applied carburetor heat, but the engine continued to run rough. The pilot then verified that the magnetos were on BOTH, that the mixture was full RICH, and closed carburetor heat. The engine continued to run rough, and the pilot declared an emergency as the airplane was unable to maintain altitude in mountainous terrain. The pilot initiated a forced landing to a logging road. Subsequently, the airplane struck trees and sustained damage to both wings. The airplane was recovered to a secure facility for further examination.

- 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.
