I'm with Bose and the others.
When I fly my own plane, which is securely hangared and only 4 of us have use of, I can preflight in 5 minutes. The MAIN things to check in a PF check are: you have enough oil, you have enough fuel, the fuel is ok, the airframe is not bent, no control surfaces are not going to fall off, there is nothing attached to the plane, all covers and locks are off and there is nothing out of the ordinary (for example a puddle of oil under the engine). Anything else serious enough to kill you probably won't show up during a PF anyway.
You can waggle your stabilator until the cows come home but it won't show the cracked engine mount or bug in the fuel line waiting to be ingested by the fuel injector.
