What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On may 21, 2014, at about 0930 pacific daylight time (PDT), a single-engine Cessna 140 airplane, N2256N, experienced a partial loss of engine power during climb out after departing from runway 02 at the Nut Tree Airport in Vacaville, California. The commercial-rated pilot privacy data omitted and one passenger, who received only minor injuries during a forced landing were onboard. The airplane was substantially damaged.
The pilot reported that the engine lost partial power shortly after takeoff while climbing over the runway at approximately 150 feet. In an attempt to fix the problem, the pilot cycled the throttle twice to no avail. With approximately 1000 feet of runway remaining, the pilot elected to land the airplane. After landing, the pilot over-reacted and applied excessive brakes, the airplane nosed-over, and came to rest inverted 500 feet from the end of the runway.
The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Comments: a search of faa's databases did not disclose a violation, accident, or incident history for this airman.
On may 27, 2014 FAA a/w inspector stated the following:
Discussion with privacy data omitted who is also a certificated A&P mechanic to pull the spark plugs for observation. The findings were it appeared the engine was ?running rich?, possible due to a combination of factors such as a rich mixture setting, two pilots on board, climb out rate of climb and airspeed technics which could possibly be a cause to the engine slight loss of power, no other noted defects.
This report may be revised with additional evidence.
