N414LLoehle Aircraft LOEHLE P-40 · 1994

Shortly after initiating the takeoff and just after the landing gear of the experimental airplane left the ground, the airplane banked about 10 degrees left. The pilot initially assumed the bank had been induced by a crosswind, but the bank continued to increase as the airplane's speed increased. The pilot then leveled the airplane about 75 feet above the ground and slowed to 50 mph in an attempt to evaluate the control issues. While applying full right control stick and full right rudder, the bank would not decrease, so the pilot attempted to perform a forced landing with the bank angle now reaching about 45 degrees. When the pilot decreased engine power the nose of the airplane rose, the airplane stalled, and then spun to the left. The airplane subsequently impacted the ground resulting in substantial damage to the nose, cockpit, and left wing. The airplane was examined at the scene by a Federal Aviation Administration inspector. The inspector noted that the airplane's ballistic parachute system had not activated and he was not able to observe any broken flight control cables, but due to the extent of impact-related damage to the airplane, was unable to verify operation of the ailerons. When asked how the accident could have been prevented, the pilot stated, "Immediate precautionary/aborted landing should have been undertaken upon first indication of control issues on takeoff…"
