Unregistered CGS Hawk: Accident occurred May 17, 2017 at Weaver Airport (9OH6), Findlay, Hancock County, Ohio

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf 

Analysis 

The pilot of the tailwheel-equipped airplane reported that, during takeoff, the "wind got more gusty than [he] could handle being too low and slow." The airplane aerodynamically stalled and impacted the ground.

The airplane sustained substantial damage to the right wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

A review of recorded data from the automated weather observation station located about 5 nautical miles west of the accident airport revealed that, about 42 minutes before the accident, the wind was from 200° at 18 knots, gusting to 28 knots. The takeoff direction is unknown. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during takeoff, which resulted in an aerodynamic stall. 

Findings

Angle of attack - Capability exceeded (Cause)
Airspeed - Not attained/maintained (Cause)

FINDLAY — A small airplane crashed Wednesday evening near Findlay after high winds affected its path.

Dale Weaver, 79, of Findlay, flew a 1983-1984 CGS Hawk ultralight aircraft in Marion Township near Findlay, Hancock County Sheriff’s Office Deputy T.J. Brooks said in a press release. He was flying the plane low above the field east of township Road 242, near Forest Lake Drive in Marion Township.

High winds and the slow speed of the aircraft caused the engine to stall, crashing the plane into the field. 

The aircraft landed on both tires and sustained minor damage.

Weaver was transported to Blanchard Valley Hospital with unknown injuries by Hanco EMS. The hospital didn’t have Weaver listed in its directory Thursday morning.

The investigation continues through the sheriff’s office and the Federal Aviation Administration and National Transportation Safety Board.
