Analysis

The pilot was on an IFR flight plan flight when the engine alternator failed and the aircraft battery became so depleted that the nav and com equipment failed. Pilot was able to descend to VFR conditions. He stated he used the checklist to manually extend the landing gear but each time he released the crank, it turned in a reverse direction by itself and he fanally elected to land gear-up alongside the runway. He later stated that he did have the gear handle down but forgot to pull the landing gear motor circuit breaker.
