Aerodynamic Stall / Spin: Cessna 172N Skyhawk, N734HF; accident occurred April 01, 2020 at North Perry Airport (KHWO), Hollywood, Broward County, Florida









Aviation Accident Final Report - National Transportation Safety Board 

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Orlando, Florida 

Investigation Docket - National Transportation Safety Board:


Location: Hollywood, FL
Accident Number: ERA20CA146
Date & Time: 04/01/2020, 1430 EDT
Registration: N734HF
Aircraft: Cessna 172
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 3 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

Analysis

The flight instructor reported that, during a flight review, the private pilot completed five touch-and-go landings in gusting wind conditions. During the landing flare for the sixth touch-and-go landing, a strong wind gust forced the airplane out of ground effect, and the instructor called for a go-around. During the go-around, the pilot did not add full power, and the instructor took the flight controls; however, the airplane had already stalled. Subsequently, the airplane descended, impacted the left side of the runway, continued off the runway into grass, and nosed over. The right wing and vertical stabilizer sustained substantial damage. The instructor reported that there were no preaccident mechanical malfunction or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to apply full engine power during the initiation of a go-around in gusting wind conditions and his exceedance of the airplane's critical angle of attack, which resulted in an aerodynamic stall at low altitude, and the flight instructor's delayed remedial action. 

Findings

Personnel issues Use of equip/system - Pilot
Personnel issues Aircraft control - Pilot
Personnel issues Delayed action - Instructor/check pilot
Aircraft Angle of attack - Capability exceeded
Environmental issues Gusts - Effect on operation
