Federal Aviation Administration (FAA), DOT.


Final rule; correction.


The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to Lycoming Engines TSIO-540-AK1A, and Continental Motors, Inc. TSIO-360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines, with certain Hartzell Engine Technologies (HET) turbochargers, model TA0411, part number 466642-0001; 466642-0002; 466642-0006; 466642-9001; 466642-9002; or 466642-9006, or with certain HET model TA0411 turbochargers overhauled or repaired since August 29, 2012. The Summary paragraph and the Applicability paragraph list an incorrect engine model for Lycoming Engines. This document corrects those errors. In all other respects, the original document remains the same.


This final rule is effective January 14, 2013. The effective date for AD 2012-24-09 (77 FR 72203, December 5, 2012) remains December 20, 2012.
