Airworthiness Directive · Amendment 39-17279 · Lycoming Engines and Continental Motors, Inc. Reciprocating Engines
Lycoming Engines and Continental Motors, Inc. Reciprocating Engines
Superseded. A later AD replaced this one: AD 2013-21-02. Comply with the one in force.
This 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 any of the following turbochargers installed:
(1) Hartzell Engine Technologies (HET) model TA0411 turbochargers, part numbers (P/Ns) 466642-0001; 466642-0002; 466642-0006; 466642-9001; 466642-9002; and 466642-9006, with serial numbers (S/Ns) listed in Table 2 of HET Alert Service Bulletin No. 048, dated November 16, 2012, installed.
(2) HET model TA0411 turbochargers having a turbine wheel, P/N 410188-0019, with any of the turbine wheel S/Ns H120716 through H121988, installed.
(3) HET model TA0411 turbochargers overhauled or repaired since August 29, 2012, using a turbine wheel, P/N 410188-0019, with any of the turbine wheel S/Ns H120716 through H121988, installed.
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.
Before further flight, remove from service the turbochargers identified in paragraph (c) of this AD, unless already done.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
