In his seminal book Stick and Rudder, Wolfgang Langewiesche states the rudder “…causes the greatest difficulty for beginners,” and “….even the more experienced pilot often has trouble using it correctly.” Commenting on improper rudder use as a contributing factor in accidents, he states, “In the typical fatal accident, which involves a stall and a spin, misuse of the rudder is almost always partly to blame….”

After a short-field takeoff, the Cessna 172 was pitched to a high angle of attack (AoA) to maintain best-angle-of-climb speed (VX). At 100 feet agl, the left wing dropped slightly, then the airplane rolled left, eventually rolling inverted. It crashed in a nose-down attitude, killing the pilot.
