The landing rules are pretty explicit and well covered. I have no interest in talking about shed parts and landing.

AMA rule 7 states: The time will end when the model touches the ground or any ground-based object.

This rule does not exclude "parts" of the model and the landing rule clearly includes parts of the model as the model, i.e. you cannot say that the canopy is not the model it is only a part of the model.

Is the prop part of the model? Is the canopy part of the model? You can't have one definition for landing and another for launching. If a shed part zeros the landing they why is the shed part touching the ground on launch not considered a clock stopper? So if someone throws a prop and it skewers another competitor the time should not be stopped, but a canopy pops off a Radian on landing and you get a zero?

Leaving it up to every CD is only asking for anarchy.

BTW - Good points, Don. Pilot and spectator safety is numero uno.

However, if the rule remains ambiguous, as CD I will stop the clock when a shed part hits the ground on launch and I don't think that someone who has a thrown prop sticking out of his arm would appreciate a comment like "Hey, at least it wasn't the plane." If, God forbid, that were to happen I would zero the flight (at a minimum) - even though "technically" the plane did not hit him.

But the "not safely flyable" only applies IF the model is damaged during landing. Change "and" to "or" in the above quoted section and then damage incurred during flight would apply (thrown prop & resulting damaged fuse from vibration). But the way the rule above is written, one would first have to damage the plane during landing for the second half of the sentence to apply.
