No matter what work has been accomplished, it behooves the prudent pilot to conduct a very, very thorough preflight and run-up before the airplane is returned to the sky. A pilot recently took off from King County International Airport in Seattle, Washington, in a Cessna Cardinal on what was described as a post-maintenance test flight. According to the National Transportation Safety Board, the pilot reported that just after liftoff, the aircraft started rolling to the left. He applied corrective right aileron, but that resulted in the roll to the left becoming accelerated. As the aircraft approached 80 degrees of bank, the left wing contacted the surface and the aircraft cartwheeled into the ground.
