Rear cowl flap motor intermittancy.

[Paul462]

Help!

Last Sunday upon landing, the rear cowl flaps were still full open, even though the handle on the panel had been in the "closed" position for the previous 45 minutes. I cycled the rear cowl flap panel handle handle several times, and the rear cowl flaps didn't move.

A few days later I turned on the master switch, and the rear cowl flaps closed (the panel handle was in the "closed" position) - the cowl flaps worked fine, and the mechanic could find nothing wrong with them!

Has anybody had a similar experience, or might know what could cause the rear cowl flaps to freeze up when the engine was hot, and then work completely normally a few days later?

Thanks!

Paul
