NTSB narrative
THE ACFT DESCENDED AT A FLAT ANGLE UNDER POWER INTO TREES AFTER THE ENGINE LOST POWER. THE PILOT TOOK OFF AT 1010 FOR A SIGHTSEEING FLIGHT. THE TEMPERATURE WAS 78 AND THE DEW POINT WAS 65 DEGREES F. AFTER ABOUT 30 MINUTES OF FLIGHT THE PILOT TURNED TO AVOID CLOUDS AND BEGAN TO LOSE ALTITUDE. HE ADDED THROTTLE BUT COULD NOT GET FULL POWER. THE AIRCRAFT CONTINUED TO DESCEND WITH BEST CLIMB AIRSPEED AND FULL THROTTLE. MAINTAINING WHAT POWER HE COULD AND A FLAT RATE OF DESCENT THE PILOT FLEW INTO A SLIGHTLY UPWARD SLOPING GROUP OF TREES IN THE MAKAHA VALLEY.

Source notes (4)
- 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.
