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.
A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract
We are adopting a new airworthiness directive (AD) for 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 (P/N) 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. This AD requires removing the affected turbochargers from service before further flight. This AD was prompted by a report of a turbocharger turbine wheel that failed a static strength test at its manufacturing facility. We are issuing this AD to prevent turbocharger turbine wheel failure, reduction or complete loss of engine power, loss of engine oil, oil fire, and damage to the airplane.
