Cessna Citation I/SP — Service Bulletins

This document outlines the final rule regarding the Aging Airplane Program, specifically addressing widespread fatigue damage (WFD) in transport category airplanes, including the Cessna Citation I/SP. It mandates that design approval holders evaluate their airplanes to establish a limit of validity (LOV) for the engineering data supporting their structural maintenance programs. The rule applies to turbine-powered airplanes with type certificates issued after January 1, 1958, and requires operators to incorporate the LOV into their maintenance programs. The document details the requirements for existing and future airplanes to ensure they are free from WFD, which can lead to catastrophic failures. It emphasizes the importance of maintenance actions to prevent WFD and outlines the regulatory framework for compliance.

• The rule applies to turbine-powered airplanes with a type certificate issued after January 1, 1958.
• Operators must incorporate a limit of validity (LOV) into their maintenance programs.
• Widespread fatigue damage (WFD) can lead to catastrophic failures if not managed properly.
• Design approval holders must establish and demonstrate the LOV to ensure safety.
• The rule aims to prevent accidents and extend the economic life of airplanes.
