The pilot reported that, during takeoff, everything appeared "good" until he saw a yellow warning light illuminate. He remembered seeing the letters "hydr…" on the light and became concerned about the landing gear. He decided to abort the takeoff and reduced power and held back pressure on the yoke. He added that he intentionally "let" the airplane go left over grass. As the airplane decelerated, he saw a taxiway sign ahead, the stall warning horn sounded, and the airplane settled back onto the ground on the taxiway sign. The pilot then pulled the yoke full aft and added right brake, and the airplane impacted a ditch. A Federal Aviation Administration (FAA) inspector corroborated the pilot's statement.

The airplane sustained substantial damage to the right wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The FAA inspector reported that, during postaccident examination, no warning lights were noted.

The pilot reported that, before the flight, he performed weight and balance calculations. He added that the airplane was more than 300 lbs over the maximum allowable gross weight and was "heavy aft." He reported that he had seven people on board the six-seat airplane; six people were sitting in a seat, and one person was sitting on the floor.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain the runway heading during an aborted takeoff, which resulted in a runway excursion and collision with a sign and terrain. Contributing to the need to abort the takeoff was the pilot's improper decision to take off with the airplane over its maximum gross takeoff weight.


Heading/course - Not attained/maintained (Cause)
Maximum weight - Capability exceeded (Factor)
CG/weight distribution - Capability exceeded

Personnel issues
Aircraft control - Pilot (Cause)
Decision making/judgment - Pilot (Factor)

Environmental issues
Sign/marker - Effect on operation

  1. I'm guessing it is great to be lucky if you are also stupid.

    Glad no one was hurt.

  2. The pilot said he took off knowing he was 300 lbs. heavy and with more people than seats. Wow.

  3. You've got to be kidding me. 300lbs over weight, aft heavy, with a passenger on the floor not in a seat? That pilot is a danger and his license should be revoked!
