You are over reacting. You, as a student pilot with a CFI on board you are not liable. The report also states:
the instructor lowered the collective, applied aft cyclic, right pedal, and rolled off the throttle to idle.
Which is good for you. The only downside is, the FAA and not the NTSB will prolly take your statement as there were no injuries….The NTSB does not deal with these other than writing the report.
If you hav any issues, just cite the NTSB Walkup case, known as the “Walkup Decision”, which basically will put the CFI at fault.
Walkup Case
Although it was challenged and is now under the latest name…..old timers still call it Walkup.
