## Probable cause

THE PILOT'S SELECTION OF UNSUITABLE TERRAIN AND THE DELAY IN ABORTING THE TAKEOFF.

## Sequence of events

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

- On ground/water collision with object, takeoff - aborted
  - aborted takeoff - delayed, pilot in command (cause)
  - object - building(nonresidential)
  - object - fence

## Analysis

DURING A TAKEOFF FROM A ROUGH GRASSY AIRSTRIP, THE GYROPLANE HAD NOT ATTAINED SUFFICIENT AIRSPEED FOR LIFTOFF AT MID-FIELD. THE PILOT ABORTED THE TAKEOFF AND APPLIED THE BRAKES. THE GYROPLANE DID NOT HAVE SUFFICIENT ROOM TO STOP BEFORE COLLIDING WITH A FENCE AND A BUILDING. THE PILOT REPORTED THAT THERE WERE NO MECHANICAL FAILURES OR MALFUNCTIONS WITH THE GYROPLANE AT THE TIME OF THE ACCIDENT.
