## Summary

We propose to rescind an airworthiness directive (AD) for Lycoming Engines model TIO 540-A series reciprocating engines. The existing AD, AD 71-13-01 (Amendment 39-1231) resulted from a report of a failed fuel injector tube assembly.

Since we issued AD 71-13-01, we became aware that Lycoming Engines no longer supports Service Bulletin (SB) No. 335A, which was incorporated by reference in AD 71-13-01. The intent of the requirements of that SB is now in Lycoming Engines Mandatory SB No. 342F. This proposal to rescind AD 71-13-01 allows the public the opportunity to comment on the FAA's determination of the duplication of requirements in another AD, before we rescind the engine-level AD.
