Porpoise buckles Cessna

Aircraft: Cessna 172. Injuries: None. Location: Grand Forks, N.D. Aircraft damage: Substantial.

What reportedly happened: The student pilot was practicing landings with his flight instructor. The airplane touched down right of the runway centerline and began to bounce.

The student attempted to realign the airplane with the centerline. The bouncing continued with an escalating intensity.

The instructor took the controls with the intention of aborting the landing, but before he could establish a climb the airplane experienced an additional hard landing. The firewall was substantially buckled.

Probable cause: The CFI’s delayed remedial action to the student pilot’s bounced landing and subsequent loss of aircraft control.

    Hind-site LOL
    After i bounced and bent a nose gear my instructor reminded me to fly the plane to runway and then try to keep it from landing as long as i could as it will quit flying without my added help. Keep it in the middle and maintain a proper glide to maintain proper airspeed to finish the landing. (Ive quit flying 10 feet off ground as well LOL)
    Ive got many 100’s of landings since and never bent anything since. Most passengers usually dont know when we touch down.
    That all goes to Having an Instructor who made me do landings until i got sick of them but i can say it allowed me to become confident after a really bad landing and experience early in my training.
    Ive learned that when i only have 30 minutes to fly at times i just do landings and pattern flight. I feel you cant get enough practice in landings in all conditions.

    Happened very early on when I moved up from a Cessna 150 to a 172. Bent the nose wheel, and I did a go-around. I got my instructor to show me what I did wrong, which was to attempt to drive the plane onto the runway rather than go for a full-stall landing. Some lessons come hard. Now, 43 years later, I’ve never bent another airplane (yet). Thanks, Meg, for the memories.
