Re: \'play\' in the flaps
If the flap hardware tolerences were too tight the flaps could easily become jammed. The A&P that inspects the airplane will check for proper condition and tolerences during each inspection and will replace any components that are out of spec. from wear or damage. There is usually very little need to adjust the flap actuating hardware during the normal lifespan of the components.

Re: \'play\' in the flaps
OK thanks for the answer... reason I asked is because a student asked me; let's say there is NO play in the actuating rod, what does this mean to a pilot doing a preflight?
I've flown with almost no play and I've flown with a fair amount... never had problems either way, though I've heard you want to have SOME play.

Re: \'play\' in the flaps
No play at all would be an indication of poor lubrication of the push rod ends possibly corrosion or damage that is causing binding. If the pushrods are binding up, chances are the whole rigging system needs attention.

This is exactly true.
I was preflighting a C172, and upon putting the flaps down for part of the preflight, I heard a scratching metal noise i immedialty stoped the flaps and turned the master off. Looking down the wing, the left flap appeared to have twisting of metal along the guide rails. They had to ground the a/c for a few days to get it fixed.
