What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft initially touched down at Mcgill airstrip (18II) approximately 25 yards from the end of the grass strip in a north to south direction with gusting winds from the south to southwest direction. The aircraft encountered a hump in the airstrip at approximately 160 yards from where he initially touched down. The hump in the runway launched the aircraft airborne after bleeding off speed from the original touch down point. The aircraft touched down a second time, at which point the aircraft ground looped at approximately 170 yards from the end of the airstrip. The aircraft then veered left and entered a freshly plowed field to the left of the airstrip causing the aircraft to come to an abrupt stop, nose over and flip upside down. The aircraft came to rest approximately 15 yards off of the east side of the runway upside down. The damage to the aircraft was minor, and primarily to the propeller and engine mount. There was some minor damage to the left wing as well as to the left wing support strut. There was no damage to the fire wall or any other substantial structure or control surfaces.
