What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 09/09/2021, at approximately 09:51 EST, N782JA, a 2007 Cessna 172S, s/n: 172S10560 privacy data omitted, to provide flight instruction. The aircraft declared mayday due to loss of engine power and executed a forced landing. The aircraft overshot runway 23 and ended up inverted on an adjacent golf course south west of the departure end of runway 23 in Venice FL (vnc), resulting in substantial damage. The aircraft sustained damage to both wings with what appears to have underlying damage to the frames and stringers, bent wing struts, damage to the flap areas, vertical fin tip, and crumpling to the engine firewall. Additional damage was observed on the propellers, engine cowlings, nose gear strut and numerous places around the empennage.
The PIC stated, while on an instrument approach into Venice FL (vnc). He canceled IFR with tpa approach and started his decent into vnc with 1900 RPM. According to the PIC, at approximately, 1700 ft. he tried to level off and maintain that altitude. He attempted to push the throttle control, he stated there was no change to the aircraft RPM. He tried to troubleshoot the issue without success. Realizing that there was a problem with the RPM which he could not fix in flight. The PIC stated he declared a mayday due to loss of engine power and decided to execute a forced landing. Several attempt to make throttle control changes were made but the speed of the aircraft would not decrease. The PIC further stated, in a last attempt realizing he would not be able to decrease the speed he decided to put the nose down to initiate a force landing. He forced the nose down and hit the grass with the front wheel. He believes the aircraft bounced a couple of times before exiting the runway.
A post-accident on-scene examination of the aircraft revealed that the hardware (bolt, washer, nut, cotter pin) on the linkage connecting the fuel injector servo to the throttle cable was missing. This inspector observed a bolt, washer, and nut laying inside the engine cowling. A review of the aircraft records indicated the engine was replaced on this aircraft on August 30, 2021 and an engine 50HR inspection was performed on September 7, 2021. The wings were removed from the aircraft onsite and the aircraft was transported to a nearby maintenance facility.
The pilot and passenger were on board the aircraft, no one was injured. There was property damage to the golf course but no ground injuries.
