Probable cause
The improper installation and inspection of the carburetor throttle linkage arm.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The flight instructor and the student pilot were practicing touch and go landings. Just after the second takeoff, the engine power dropped to idle. Despite emergency procedures, the engine power would not increase and a forced landing was made in a residential area. During the descent, the airplane impacted wires and a traffic light pole. Post accident inspection revealed the throttle arm had fallen off the carburetor shaft. The unit also had not been safetied in place.
