Summary
On August 10, 2011, a Aircraft Mfg & Design LLC CH750 STOL (N799US) was involved in an incident near New Washoe City, NV. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot under instruction's control interference and the CFI's inadequate supervision of the flight.
The pilot under instruction (PUI) and certified flight instructor (CFI) were practicing slow flight at approximately 200 feet above ground level when the CFI noticed that the airplane was sinking and the airspeed was low. He instructed the PUI to add power in order to maintain altitude; the PUI did, but the airplane continued to sink. The CFI then added more power and pitched the nose up in an attempt to gain altitude and arrest the sink, but in response, the PUI pushed the nose down and the airplane made an inadvertent landing, bouncing twice and coming to rest inverted. The airplane's firewall and vertical stabilizer were substantially damaged. The CFI reported no preimpact mechanical malfunctions or failures that would have precluded normal operations.
This incident is documented in NTSB report WPR11CA360. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N799US.
