Takeoff Attempt
The pilot reported that the airplane was loaded to its maximum gross weight. During the takeoff roll, the airplane did not appear to accelerate normally. The pilot anticipated a liftoff speed of 60 to 65 knots. When the expected acceleration did not occur, the pilot decided to abort the takeoff.
Abort and Outcome
The pilot applied the brakes to stop the airplane. However, the brakes locked on the wet grass surface, causing the airplane to skid. The airplane departed the runway at its end, crossed an adjacent road, and eventually came to a stop. The pilot did not indicate any mechanical difficulties with the airplane prior to the accident.
Postaccident Examination
A postaccident examination of the airplane did not disclose any evidence of mechanical malfunction.
