What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)A/c departed runway 27L and impacted several pine trees, before coming to rest in about 12 ft of water. The a/c was substantially damaged. (.4)at about 150 feet AGL, during takeoff climb, the flight experienced a partial engine power loss due to an intermittently operative right-hand magneto condenser. The pilot stated the airplane stalled and collided with trees, eventually coming to rest partially submerged in a marina basin. Disassembly examination of the core engine and all fuel components revealed no mechanical abnormalities. Bench testing and disassembly examination of the right-hand magneto condenser revealed no damage attributable to the submersion and a short to ground that would have rendered the magneto inoperative. Using the pilot's estimate of fuel aboard, the occupant's weights, and the faa's estimate of the baggage and cargo aboard, computations revealed the aircraft was about 272 pounds over maximum gross takeoff weight. The pilot was not bfr current, nor was the conversion to a three-bladed propeller properly documented in the maintenance records.
As the FAA filed it
(-23)A/C DEPARTED RUNWAY 27L AND IMPACTED SEVERAL PINE TREES, BEFORE COMING TO REST IN ABOUT 12 FT OF WATER. THE A/C WAS SUBSTANTIALLY DAMAGED. (.4)AT ABOUT 150 FEET AGL, DURING TAKEOFF CLIMB, THE FLIGHT EXPERIENCED A PARTIAL ENGINE POWER LOSS DUE TO AN INTERMITTENTLY OPERATIVE RIGHT-HAND MAGNETO CONDENSER. THE PILOT STATED THE AIRPLANE STALLED AND COLLIDED WITH TREES, EVENTUALLY COMING TO REST PARTIALLY SUBMERGED IN A MARINA BASIN. DISASSEMBLY EXAMINATION OF THE CORE ENGINE AND ALL FUEL COMPONENTS REVEALED NO MECHANICAL ABNORMALITIES. BENCH TESTING AND DISASSEMBLY EXAMINATION OF THE RIGHT-HAND MAGNETO CONDENSER REVEALED NO DAMAGE ATTRIBUTABLE TO THE SUBMERSION AND A SHORT TO GROUND THAT WOULD HAVE RENDERED THE MAGNETO INOPERATIVE. USING THE PILOT'S ESTIMATE OF FUEL ABOARD, THE OCCUPANT'S WEIGHTS, AND THE FAA'S ESTIMATE OF THE BAGGAGE AND CARGO ABOARD, COMPUTATIONS REVEALED THE AIRCRAFT WAS ABOUT 272 POUNDS OVER MAXIMUM GROSS TAKEOFF WEIGHT. THE PILOT WAS NOT BFR CURRENT, NOR WAS THE CONVERSION TO A THREE-BLADED PROPELLER PROPERLY DOCUMENTED IN THE MAINTENANCE RECORDS.
