Aircraft involved

Probable cause & findings

THE CFI'S INADEQUATE IN-FLIGHT PLANNING, AND HIS INADVERTENT GEAR-UP LANDING. FACTORS INCLUDE THE CFI'S DIVERTED ATTENTION.

Factual narrative

On Tuesday afternoon, October 5, 1993, at 1340 Pacific daylight time, a Cessna 172RG, N16ED, operated by Avia Flight Services, impacted the runway while landing at the Corvallis Municipal Airport, Corvallis, Oregon. There was no flight plan filed for the local training flight, which took off at 1225. The flight was conducted under 14 CFR 91 in visual meteorological conditions. The certified flight instructor and the commercial pilot were not injured in the accident. The aircraft was substantially damaged. There was no fire. Flight instructor Anderson reported that he pulled the landing gear circuit breaker to deactivate the warning horn while he was conducting training for commercial pilot Foster. He said that after finishing several training maneuvers, he reduced the throttle while over the airport to simulate an engine failure, and the commercial pilot initiated a forced landing to the runway. The landing gear handle was placed in the down position, but the gear did not fully extend. Just as the aircraft was touching down on the runway, the CFI noticed that the gear was not fully down, but there was not sufficient time for remedial action. The aircraft then impacted on the runway with the gear partially extended. WHILE EXECUTING COMMERCIAL FLIGHT TRAINING MANEUVERS, THE CFI PULLED THE CIRCUIT BREAKER FOR THE LANDING GEAR. AT THE COMPLETION OF THESE MANEUVERS, THE CFI PULLED THE ENGINE TO IDLE TO SIMULATE AN ENGINE FAILURE. THE STUDENT THEN EXECUTED A FORCED LANDING, DURING WHICH THE GEAR HANDLE WAS PLACED IN THE DOWN POSITION. NEITHER PILOT REMEMBERED THAT THE LANDING GEAR CIRCUIT BREAKER HAD BEEN PULLED, AND THEREFORE THE GEAR DID NOT FULLY EXTEND, AND THE GEAR WARNING HORN DID NOT SOUND. THE CFI NOTICED THE GEAR WAS NOT FULLY EXTENDED JUST AS THE AIRCRAFT WAS TOUCHING DOWN ON THE RUNWAY, BUT THERE WAS INSUFFICIENT TIME FOR REMEDIAL ACTION.
