## Analysis

THE PLT REPORTED THAT AFTER HE TAXIED TO THE RWY, THE #1 OIL TEMP WAS NOT UP TO THE MINIMUM TEMP. HE SET THE PARKING & ADVANCED THE #1 THROTTLE TO 1500 RPM UNTIL THE ENGINE WARMED UP. WHEN BOTH OIL TEMPS WERE WITHIN LIMITS, HE ADVANCED BOTH THROTTLES TO 30 INCHES MP & 2250 RPM FOR A PRETAKEOFF CHECK. AT THAT TIME, HE USED THE NORMAL (TOE) BRAKES, SINCE THE PARKING BRAKE WOULD NOT HOLD THE ACFT ABOVE APRX 1700 RPM. HE THEN APPLIED FULL POWER & RELEASED THE BRAKES FOR TAKEOFF. AS HE STARTED TO ROLL WITH A SLIGHT LEFT X-WIND, THE ACFT BEGAN DRIFTING LEFT. HE CORRECTED WITH RIGHT RUDDER, SOME RIGHT BRAKE & RIGHT AILERON. THE ACFT THEN BEGAN DRIFTING RIGHT & THE PLT SUSPECTED A WIND-SHIFT FROMTHAT DIRECTION. HE APPLIED LEFT RUDDER & RIGHT AILERON, BUT THE PLANE VEER RIGHT, WENT OFF THE RWY & HEADED FOR A DITCH.UNABLE TO STOP, THE PLT TRIED TO CLEAR THE DITCH. AS THE ACFT BECAME AIRBORNE, THE LEFT WING DROPPED & HIT THE GROUND, AND THE ACFT YAWED & CRASHED. THE PARKING BRAKE WAS FOUND PARTIALLY ENGAGED. TIRE MARKS WERE EVIDENT ON THE RWY.

## 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.
