## Summary

This document proposes to revise an earlier proposed airworthiness directive (AD) that would apply to certain Fairchild Aircraft SA226 and SA227 series airplanes. The earlier NPRM would have required you to replace the brake shuttle valves with parts of improved design and install a shield over the hydraulic lines. The earlier NPRM resulted from a report of a wheel brake system malfunction caused by a faulty brake shuttle valve on an affected airplane. Evaluation of the public comments on the NPRM reveals the need to also include airplanes that have an anti-skid system in the Applicability of the proposed AD. In addition, we are proposing a requirement of replacing the rubber fuel hose with a metal device for the SA226 series airplanes. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these additional actions.
