## Analysis

PLT WAS AWARE RUNWAY HAD A PRONOUNCED DIP JUST PRIOR TO ROTATION AREA OF HIS ACFT. PASSING THE DIP ON TAKEOFF ROLL, HE FELT A 'SHIMMY' WHICH HE ATTRIBUTED TO NOSE GEAR REACTION TO THE DIP. PLT CONSIDERED ABORTING TAKEOFF, BUT FELT INSUFFICIENT RUNWAY REMAINED. ON INITIAL CLIMB, ACFT BEGAN SEVERE VIBRATION, CLIMB ABOVE 100 FT AGL NOT POSSIBLE PLT MANEUVERED TO AVOID TALL TREES IN WOODED AREA AHEAD BUT COULD NOT MAINTAIN SAFE ALTITUDE AND AIRSPEED; ALLOWED THE ACFT TO STALL/MUSH INTO TREES. PLT STATED INITIAL CHECKOUT IN MAKE/MODEL INCLUDED INSTRUCTIONS TO 'HOLD NOSE ON GROUND UNTIL REACHING 90 KTS.' FAA INSPECTOR STATED THIS SPEED IS EXCESSIVE AND WILL CAUSE THE ACFT TO 'WHEELBARROW.' INVESTIGATION REVEALED NOSEDOWN TRIM SETTING, PROP MARKS ON RWY AND ALL PROP BLADES BENT REARWARD 4 INCHES FROM TIPS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
