Accident Overview
A flight instructor reported that during a night landing, with the student pilot at the flight controls, the aircraft experienced an abnormal touchdown sequence. The instructor described feeling the airplane "hop a little" followed by an immediate drop of the left wing. Subsequently, the airplane "shifted to the right, the nose lifted, and as the airplane settled the airplane nosed over."
Aircraft Damage
Post-accident inspection revealed substantial damage to the left wing, the right wing lift strut, the vertical stabilizer, and the rudder. The flight instructor did not report any preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
Instructor's Observations
The flight instructor, reflecting on the accident, offered a safety recommendation. He stated, "I believe the accident could have been prevented if I personally executed the landing and not assisted my student in the landing." Additionally, he noted that "the length of the day and emotional fatigue played a big factor" in the accident.
