On April 12, 2011, at 0853 Pacific daylight time, a Cessna 150L, N11630, sustained substantial damage following a loss of aircraft control and impact with a hangar door at Corona Municipal Airport (AJO), Corona, California. The private pilot received minor injuries and his passenger received serious injuries. Fly Corona was operating the airplane under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed for the personal local flight. A flight plan had not been filed. The pilot reported that he was practicing a touch-and-go landing and was high, so he “pulled up on the controls.” He realized the airplane was about to stall and added power. The airplane turned left about 45 degrees, bounced once in the adjacent grass, and crossed a taxiway. The airplane subsequently impacted a hangar. The airplane’s engine section back to the firewall went through the closed hangar door. Both wings and the cabin area of the fuselage were badly bent and wrinkled. Postaccident examination of the engine, airframe, and flight controls was performed by a Federal Aviation Administration inspector. No deficiencies were noted that would have precluded normal airplane operation. The flaps were in the full down position at the time of the accident.
