Analysis

According to the flight instructor, after a normal preflight inspection and engine run-up, the student pilot taxied to the runway for takeoff and began the takeoff roll. Everything seemed normal as the airplane accelerated; however, as the airplane rotated, it started to yaw left. The instructor attempted to assist the student correct the left yaw by applying right rudder. He was unable to correct the left yaw, so he took over the flight controls and aborted the takeoff. The airplane bounced to the left and impacted a retention pond bank. A Federal Aviation Administration inspector who examined the airplane reported that the forward fuselage and firewall were buckled, that the nosewheel steerage linkage was broken, and that rust was noted on the fractured surfaces.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The failure of the nosewheel steerage linkage during takeoff, which resulted in a loss of directional control and impact with an obstacle during an attempted aborted landing.

Findings

Aircraft Landing gear steering system - Failure
Aircraft Directional control - Attain/maintain not possible
Environmental issues (general) - Effect on operation

  2. If they weren’t both sitting on each other’s lap from the right seat as indicated, perhaps they would have been able to overcome simple, basic, predictable p-factor. Hopefully this is a career ender in order to save humanity.
