Investigation Docket - National Transportation Safety Board:


Location: Elkton, Florida
Accident Number: GAA19CA412
Date & Time: July 14, 2019, 09:21 Local
Registration: N35585
Aircraft: Cessna 172 
Aircraft Damage: Substantial
Defining Event:
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Instructional

Analysis

The flight instructor reported that he had demonstrated a simulated engine failure and recovery at altitude to the pilot under instruction, and he subsequently asked the pilot to perform a simulated engine failure and recovery. The instructor allowed the pilot to descend over an open field, and he recalled instructing the pilot to "recover" and abort the landing about 200 ft above ground level. However, the pilot failed to do so, and the flight instructor took the controls. The airplane subsequently stalled, impacted terrain, and nosed over. The airplane sustained substantial damage to both wings and the engine mounts. The instructor reported that there were no preaccident mechanical failures or malfunctions 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 under instruction's failure to follow the flight instructor's directions and the flight instructor's delayed remedial action and subsequent exceedance of the airplane's critical angle of attack, which resulted in an aerodynamic stall.

Findings

Personnel issues Following instructions - Student/instructed pilot
Personnel issues Aircraft control - Instructor/check pilot
Personnel issues Delayed action - Instructor/check pilot
Aircraft Angle of attack - Not attained/maintained

  2. Failure of PUI to follow the direction of the instructor who used POOR JUDGEMENT in allowing things to get so far out of hand at such a low altitude.

    Jeeeez

  3. A lousy open plowed field for PUI to perform a "simulated engine failure and recovery at altitude"
    my recall, our CFI only pushed throttle to idle over a known open grassy field actually used for landing, usually private strips he had permissions to land.
