Investigation Docket - National Transportation Safety Board: https://dms.ntsb.gov/pubdms


Location: Lawrenceville, GA
Accident Number: GAA19CA020
Date & Time: 10/14/2018, 1230 EDT
Registration: N996SB
Aircraft: Cessna 172
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

The flight instructor reported that the student pilot's approach angle was too shallow. The student applied forward pressure to the yoke and the airplane's nose pitched down.

The instructor recalled that the student's pitch application was excessive, and he called for a transfer of the flight controls. However, the student remained on the controls and the instructor had to overpower the student's control inputs while the airplane was in a 45° nose down attitude.

The airplane landed hard in a level attitude, and the nose landing gear collapsed. A fire erupted in the cabin and the instructor used the fire extinguisher to attempt to extinguish the fire. Subsequently, the airplane slid to a stop on the runway, and both occupants exited as the fire consumed the cabin.

The airplane sustained substantial damage to the cabin and the wings.

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

  1. After four hours of lessons, about 1/3 of the way in training to an average first solo time, this student refused to turn over controls to the instructor during one of the most critical parts of a flight, at short final? The FAA should strike him from any further pilot development and refuse to accept his student pilot/Class III medical which apparently he doesn't yet have. The idiot nearly got both of them killed.
