OK... I've got a question. I've seen a number of aircraft around that have
had little patches and repairs made on them. Sometimes on a wing or fuselage,
sometimes on an elevator, sometimes on an aileron. I've heard that it is illegal to
patch moveable control surfaces, but yet I've seen numerous aircraft around with
repairs like that.

Does anyone know if this is true/false and which regs (chapter and verse)
dictate it?

Just curious...

Depends what the manufacturer has to say in the Service Manual or
Structural Repair manual. Cessna publishes repair procedures for their
light airplanes, including control surfaces, in the Structural Repair
chapter of their manuals.
A repair is one thing. Upsetting the mass balance of a control
surface with a repair is a serious offence, and one needs to be careful
about keeping things right.
