Cessna 172S Skyhawk, N99HV, Aerohawk LLC: Accident occurred June 10, 2017 at Lawrence Municipal Airport (KLWC), Douglas County, Kansas

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

NTSB Identification: GAA17CA351 
14 CFR Part 91: General Aviation
Accident occurred Saturday, June 10, 2017 in Lawrence, KS
Probable Cause Approval Date: 09/22/2017
Aircraft: CESSNA 172, registration: N99HV
Injuries: 2 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The flight instructor reported that, during a simulated engine failure in the traffic pattern, with gusting wind conditions, the student pilot entered a forward slip on final approach. He added that 10 to 20 ft above the runway surface, “the wind gust we were riding suddenly halted wherein the aircraft began a rapid downward descent.” The flight instructor reported that he “went for the flight controls to take command,” but the student pilot at that same time applied back pressure on the flight controls. Subsequently, the airplane touched down hard, bounced, and the flight instructor performed a go-around. The flight instructor completed the subsequent traffic pattern and landing without further incident.

The engine mounts and firewall sustained substantial damage. 

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

An automated weather observation station at the airport reported that, about the time of the accident, the wind was from 170° at 16 knots, gusting to 24 knots. The flight instructor reported that the landing was on runway 15. 

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The student pilot's incorrect control application during landing after a simulated engine failure, which resulted in a hard, bounced landing, and the flight instructor's delayed action to perform a go-around in gusting wind conditions.

Additional Participating Entity:
