It seems that a student destroyed the panel of an aircraft in an attempt to disinfect it
So the student did something to the plane which was in conflict with the instructions provided in the flight manual. For Cessnas, Section 8 contains care and cleaning instructions. Like any other operation of the aircraft, the pilot is expected to do what the flight manual says to do! (By the way, among the products under the "Never Use" category in that section, is alcohol.
So the student, while having care and control of the aircraft, failed to follow specific flight manual information on how to care for it, and it was damaged as a result. It seems clear to me who's responsibility this is, as the instructions
were available! We don't make up our own operating techniques, and making up our own care techniques is obviously a poor idea too!
