On my permit a/c it does take a full day to remove the cowls, inspection hatches, floorboards, oil change, oil filter clean, remove spats, inspect brakes, remove spinner, grease prop hub, inspect flying and landing wires, inspect and lubricate flying control system. I do all the work myself then have my inspector an A&C, go through it with me.
I normally don't get it back together to do the flight test until the following day!
