NTSB narrative
The airline transport pilot was departing a lake in a float-equipped airplane. During the takeoff initial climb, the engine rpm began decreasing, and the manifold pressure was increasing. The airplane attained about 400 feet agl, but did not continue to climb. Emergency engine failure procedures failed to restore power, and the pilot turned sharply to avoid a building. He leveled the airplane just before impact along the shore of the lake. A postaccident examination of the airplane and engine found no mechanical malfunction. The engine was placed on an engine test stand where it attained full rated rpm.
Probable cause
A loss of engine power for an undetermined reason.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2007-09-08.
