P Z L -WARSZAWA-CNPSL PZL 104 WILGAS/N: 18830758

Summary

On August 21, 2016, a P Z L -warszawa-cnpsl PZL 104 WILGA (N65ZA) was involved in an accident near Austin, NV. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's failure to maintain an appropriate descent rate during the base to final turn, which resulted in a forced landing, and an intentional aerodynamic stall. Contributing to the accident was the pilot's excessive braking, which resulted in a nose over and substantial damage to the empennage.

The pilot reported that he was landing atop a backcountry mountain ridge at an elevation of 10,250 feet. The airplane was configured with full flaps and on left base to final turn and the wing blocked his view of the ridge. The pilot reported that in the turn to final he had descended "a couple hundred feet lower" than he should have and when the ridge came into view, he realized he was too low, the airplane would not be able to climb over the ridge, and that he was forced to continue the landing. The pilot further reported that he intentionally aerodynamically stalled the airplane before landing, which resulted in the tail wheel impacting the ground first, then the main landing gear.

This accident is documented in NTSB report GAA16CA444. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N65ZA.

Analysis

The pilot reported that he was landing atop a backcountry mountain ridge at an elevation of 10,250 feet. The airplane was configured with full flaps and on left base to final turn and the wing blocked his view of the ridge. The pilot reported that in the turn to final he had descended "a couple hundred feet lower" than he should have and when the ridge came into view, he realized he was too low, the airplane would not be able to climb over the ridge, and that he was forced to continue the landing. The pilot further reported that he intentionally aerodynamically stalled the airplane before landing, which resulted in the tail wheel impacting the ground first, then the main landing gear. According to the pilot, to keep the airplane from falling off the edge of the cliff, he "locked up" the brakes, which resulted in a nose over.

The airplane sustained substantial damage to the empennage.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
