## Probable cause

The flight instructor's delayed remedial action.  Contributing factors were the gusty winds.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, takeoff - roll/run
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, dual student
  - remedial action - delayed, pilot in command(cfi) (cause)
- On ground/water encounter with terrain/water, takeoff
  - terrain condition - berm

## Analysis

The student pilot at the controls of the tailwheel-equipped airplane lost control of the vintage airplane during the takeoff roll from Runway 32.  The 1,278-hour flight instructor reported that a gust of wind caused the airplane to veer to the right, and the student pilot corrected by applying left rudder, but when the gust of wind dissipated there was excessive left rudder input.  The flight instructor reported that he took control of the airplane as the airplane was departing the left side of the runway to attempt to recover the airplane; however, the student pilot closed the throttle, which decreased the airplane's rudder authority.   The airplane then impacted a 3-foot berm just short of the PAPI for runway 32.  Wind conditions at an airport 6-nautical miles to the east of the accident site reported winds from 030 degrees at 15 knots at the approximate time of the accident.  The flight instructor reported winds from 8 to 15 knots at the time of the mishap.  Runway 32 was reported to be 3,740-foot long, by 60-foot wide.   The flight instructor reported having accumulated 520 hours in the same make and model airplane.
