Summary
On April 09, 2018, a Cessna 170 (N4133V) was involved in an incident near Big Lake, AK. All 2 people aboard were uninjured. The aircraft was destroyed.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot’s exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
The pilot reported that, during the approach to land on a gravel airstrip, he increased engine power to "extend the approach", the airplane pitched up in a nose high attitude, aerodynamically stalled and yawed to the right. Subsequently, the airplane impacted a snowbank to the right side of the airstrip. A postcrash fire destroyed the airplane.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
This incident is documented in NTSB report GAA18CA214. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N4133V.
