Summary
On April 27, 2018, a Stinson 108 (N6933M) was involved in an accident near Eliza Island, WA. 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 exceedance of the airplane’s critical angle of attack during takeoff, which resulted in an aerodynamic stall.
The pilot of the tailwheel-equipped airplane reported that, during the takeoff roll, he had difficulty staying on the runway. He added, in a telephone interview with the National Transportation Safety Board Investigator-In-Charge, that, while airborne, the airplane aerodynamically stalled into brush off the end of the runway. The airplane nosed over and came to rest inverted.
The airplane sustained substantial damage to the left wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The automated weather observation station located about 9 miles to the north-northwest reported that that, about the time of the accident, the wind was from 170° at 8 knots, gusting to 18 knots.
This accident is documented in NTSB report GAA18CA237. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N6933M.
