As an instructor that has banged airplanes into runways thousands of times with students (without ever bending metal), a few thoughts:
- The tail of the airplane struck the ground first (you can hear that at 1:04 in the video when the nose attitude was high). This force on the tail tries to pivot the nose down.
- At that very same second, you can see the student shove the stick forward, right before the students head blocks the view of the stick. They always do this when the tail hits, it scares them. This further amplifies the pivoting of the nose.
- Game over.
Where did the instructor mess up? Well. Like anything, there is usually a chain.
I would have had my hands on my lap, calmly relaxed, instead of dicking with the phone. Nervously guarding controls just makes more pilots more nervous. I'd like to have think I would have prevented the tail-strike from occurring in the first place, but, TBH that can be hard sometimes. **** happens fast. The instructor had roughly one second to identify the over-flare and take preventive action. This instructor failed to prevent the over-flare. (Mistake 1)
90% of the time as an instructor, if I come on the controls to prevent a landing crash, there are always two things I am doing:
- Holding the stick/yoke back and resisting the student who wants to shove it forward. This instructor failed to apply any yoke inputs. (Mistake 2)
- Getting on the rudder to straighten **** out. This instructor failed to apply any rudder inputs. (Mistake 3)
Usually as an instructor you don't have an option of using the throttle to help fix a situation. As you can see in the video, this stuff all happens in the matter of a single second. You work with what you can reach in that amount of time (stick/yoke and rudder). Throttle has the students hand on it and there isn't time to work that out.
Like I said. **** happens. Sometimes a student bangs a tail into the ground on an instructor. Yeah, an instructor should have prevented it, but sometimes a mistake happens. In this case though, the instructor made three critical mistakes in a row, and that is usually enough to bend metal.
