Preliminary Report: Aileron roll damages Learjet wing

Bombardier Learjet 35A, Columbus, Ohio, Jan. 10, 2007–Descending through FL200, the captain of the Airnet Systems cargo flight intentionally attempted an aileron roll and lost control. The Learjet “oversped,” said the captain, producing “excessive g loads.” The airplane recovered, but there was substantial damage
to the left wing and elevator assembly. The copilot told the NTSB that the maneuver resulted in a “nose-down unusual attitude” and a “high-speed dive.” The Safety Board has not reported why the pilot attempted such a maneuver.
