What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was practicing touch and go landings on peck lake when the acft lost power and struck trees, other circumstances are unknown. (.19) on April 26, 1999, at 1530 eastern daylight time, a dawe arnet pereyra Avii, N6123P, piloted by a private pilot, sustained substantial damage during a forced landing, following a loss of power, during initial climb from peck lake, near Fremont, Michigan. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR part 91 and was not on a flight plan. The pilot reported minor injuries. The flight was originating at the time of the accident and had the intended destination of Fremont Municipal Airport, Fremont, Michigan. (-23)04-27-99; accident investigation of homebuilt aventura ii amphibian. Accident occurred on 04-26-99, aircraft departed peck lake, white cloud, MI. Pilot claimed engine was not producing full (normal) RPM, but was commited to the take-off. Aircraft was attempting circling climb when engine quit. Acft struck top of tree just west of the lake, and crashed in clearing nose first then settled inverted. Pilot sustained minor injuries (broken fi nger/hand). On-site investigation revealed no compression in the forward cylinder. Further disassembly revealed the piston head was damaged due to detonation believed to have been caused by a lean mixture in that cyl. Operation during the detonation caused piston particles to seize the rings of the piston, score the cylinder walls and cause the engine to seize. The cause of the lean mixture may have been a fuel pump problem due to loss of case pressure in the forward cyl. Or a carburetor adjustment or restricted jet problem. Aircraft total time: 85 hours. Engine tach time 133 hours.
As the FAA filed it
PILOT WAS PRACTICING TOUCH AND GO LANDINGS ON PECK LAKE WHEN THE ACFT LOST POWER AND STRUCK TREES, OTHER CIRCUMSTANCES ARE UNKNOWN.

VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME OF THE ACCIDENT. THE PERSONAL FLIGHT WAS OPERATING UNDER THE PROVISIONS OF 14 CFR PART 91 AND WAS NOT ON A FLIGHT PLAN. THE PILOT REPORTED MINOR INJURIES. THE FLIGHT WAS ORIGINATING AT THE TIME OF THE ACCIDENT AND HAD THE INTENDED DESTINATION OF FREMONT MUNICIPAL AIRPORT, FREMONT, MICHIGAN.

FURTHER DISASSEMBLY REVEALED THE PISTON HEAD WAS DAMAGED DUE TO DETONATION BELIEVED TO HAVE BEEN CAUSED BY A LEAN MIXTURE IN THAT CYL. OPERATION DURING THE DETONATION CAUSED PISTON PARTICLES TO SEIZE THE RINGS OF THE PISTON, SCORE THE CYLINDER WALLS AND CAUSE THE ENGINE TO SEIZE. THE CAUSE OF THE LEAN MIXTURE MAY HAVE BEEN A FUEL PUMP PROBLEM DUE TO LOSS OF CASE PRESSURE IN THE FORWARD CYL. OR A CARBURETOR ADJUSTMENT OR RESTRICTED JET PROBLEM. AIRCRAFT TOTAL TIME: 85 HOURS. ENGINE TACH TIME 133 HOURS.
