Federal Aviation Administration November 6, 2009 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) to revise AD 2009-10-09, which applies to Cessna Aircraft Company (Cessna) 150 and 152 series airplanes. AD 2009-10-09 requires either installing a placard prohibiting spins and other acrobatic maneuvers in the airplane or replacing the rudder stop, the rudder stop bumper, and the attachment hardware with a new rudder stop modification kit and replacing the safety wire with jamnuts. Since we issued AD 2009-10-09, we became aware of a need to clarify certain model and serial number designations, remove the duplicate requirement of replacing the safety wire with jamnuts, and clarify the conditional acceptability of using modification kit part number (P/N) SK152-25 as a terminating action to this AD. Consequently, this AD retains the actions currently required in AD 2009-10-09, corrects model designation for certain serial numbers, removes the duplicate requirement of replacing safety wire with jamnuts, and clarifies the conditional acceptability of using modification kit P/N SK152-25 as a terminating action to this AD. We are issuing this AD to prevent the rudder from traveling past the normal travel limit. Operation in this non-certificated control position is unacceptable and could cause undesirable consequences, such as contact between the rudder and the elevator.

We are adopting a new airworthiness directive (AD) for the products listed above that would revise an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
