What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Acft did not gain altitude on take-off and was losing power, the pilot attempted to dump the fertilizer on board, and the acft crashed into tall trees 1/4 mile south of the arpt, other circumstances are unknown. (From .4) during the takeoff/initial climb, 'the aircraft lifted off about 2/3 of the way down the runway and did not accelerate.' The 'engine sound did not change.' The pilot reported the airplane 'went down into the trees' 1/4 mile from the airport. Functional testing of the fuel pump showed the fuel pump was capable of putting out sufficient pressure and flow at normal operating RPM to properly provide fuel to the fuel control unit to operate the engine. Damage precluded a functional test of the fuel control unit. Disassembly of the unit revealed 2 holes in the fuel control diaphragm. The manufacturer stated 'the damage to the fuel control is the result of impact damage.' The FAA coordinator stated that 'a tear in the diaphragm could cause a loss of power.' The reason for the loss of engine power could not be determined.
As the FAA filed it
ACFT DID NOT GAIN ALTITUDE ON TAKE-OFF AND WAS LOSING POWER, THE PILOT ATTEMPTED TO DUMP THE FERTILIZER ON BOARD, AND THE ACFT CRASHED INTO TALL TREES 1/4 MILE SOUTH OF THE ARPT, OTHER CIRCUMSTANCES ARE UNKNOWN. (FROM .4) DURING THE TAKEOFF/INITIAL CLIMB, 'THE AIRCRAFT LIFTED OFF ABOUT 2/3 OF THE WAY DOWN THE RUNWAY AND DID NOT ACCELERATE.' THE 'ENGINE SOUND DID NOT CHANGE.' THE PILOT REPORTED THE AIRPLANE 'WENT DOWN INTO THE TREES' 1/4 MILE FROM THE AIRPORT. FUNCTIONAL TESTING OF THE FUEL PUMP SHOWED THE FUEL PUMP WAS CAPABLE OF PUTTING OUT SUFFICIENT PRESSURE AND FLOW AT NORMAL OPERATING RPM TO PROPERLY PROVIDE FUEL TO THE FUEL CONTROL UNIT TO OPERATE THE ENGINE. DAMAGE PRECLUDED A FUNCTIONAL TEST OF THE FUEL CONTROL UNIT. DISASSEMBLY OF THE UNIT REVEALED 2 HOLES IN THE FUEL CONTROL DIAPHRAGM. THE MANUFACTURER STATED 'THE DAMAGE TO THE FUEL CONTROL IS THE RESULT OF IMPACT DAMAGE.' THE FAA COORDINATOR STATED THAT 'A TEAR IN THE DIAPHRAGM COULD CAUSE A LOSS OF POWER.' THE REASON FOR THE LOSS OF ENGINE POWER COULD NOT BE DETERMINED.
