Columbia Aircraft Manufacturing Airworthiness Directives

Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously the Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes

Unsafe Condition: Damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.

Why matched: Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously the Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes

Airworthiness Directives; Cessna Aircraft Company (Cessna) (Type Certificate A00003SE Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC41-550FG and LC42-550FG Airplanes

Unsafe Condition: Disbonding of the wing skin from the upper forward wing spar, as occurred in a Cessna Model LC41-550FG airplane during a production acceptance flight test, leading to a significant structural failure.
