Cessna 172N N172SV accident near Roanoke, Texas

Probable cause

The partial loss of engine power due to a failure of the throttle control rod-end to carburetor arm hardware. A contributing factor was the pilot's decision to fly the airplane without a current annual inspection.

NTSB analysis

During initial climb, the airplane's single engine experienced a partial loss of power. Unable to maintain altitude, the pilot performed an emergency landing to a field. During the landing rollout, the airplane impacted a rock and the nose landing gear collapsed, damaging the firewall. The airplane came to rest in a nose-down position and the pilot was able to exit unassisted. Following the accident, an examination of the airplane revealed that the throttle control rod-end to carburetor throttle arm hardware was missing. In addition, the airplane had not been inspected in accordance with an annual inspection during the previous year.
