Cessna 172M Skyhawk, N9664Q, Duffy's Aircraft Sales and Leasing: Accident occurred October 08, 2017 at Black River Falls Area Airport (KBCK), Jackson County, Wisconsin

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

Analysis

The pilot reported that, during landing in a gusting crosswind, the airplane landed on the left wheel first. He added that "all of a sudden it was like a huge gust of wind took the plane and just threw it to the right." The propeller struck the runway, and the airplane then exited the runway to the right 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.

A review of recorded data from the automated weather observation station located on the airport revealed that, about the time of the accident, the wind was from 190° at 9 knots, gusting to 17 knots. The airplane landed on runway 26.

The Pilot's Operating Handbook contained a section titled, "Crosswind Landing," which stated, in part: "The maximum allowable crosswind velocity is dependent upon pilot capability rather than aircraft limitations. With average pilot technique, direct crosswinds of 15 knots can be handled with safety." 

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 directional control during landing in gusting crosswind conditions.
