Narrative:

I was making a test flight and functional flight check immediately upon release from an annual aircraft and engine maintenance inspection at pdx. On takeoff, the gear did not retract. After cycling the gear switch with no result, I placed the switch in the gear down position. On fly-by, the tower confirmed my gear was down. On landing, the main gear partially collapsed and nose gear collapsed. Damage to propeller, engine, and aircraft was not substantial.
