## Summary

This document proposes to revise an earlier proposed airworthiness directive (AD) that would apply to certain Fairchild Aircraft Incorporated (Fairchild Aircraft) SA226 and SA227 series airplanes equipped with Skidmore-Wilheim Manufacturing Co. (Skidmore-Wilheim) (formerly Hydromotive) Model V1-15-1000 brake master cylinders. The earlier NPRM would have required you replace these brake master cylinders with new or overhauled units of the same design. The earlier NPRM resulted from reports of dragging brakes during taxi operations. Additional airplane models have been identified on which the unsafe condition exists or could develop. 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.
