Lycoming Engines and Continental Motors, Inc. Reciprocating Engines
This AD applies to certain Lycoming Engines TIO-540-AK1A, and Continental Motors, Inc. (CMI) LTSIO-360-RB, TSIO-360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines with a Hartzell Engine Technologies (HET) turbocharger installed that has a model number, part number, and serial number identified in Tables 1 and 2 of HET Alert Service Bulletin (ASB) No. 048, dated November 16, 2012.
We are superseding airworthiness directive (AD) 2012-24-09 for Lycoming Engines TIO-540-AK1A, and Continental Motors, Inc. (CMI) TSIO- 360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines, with certain Hartzell Engine Technologies (HET) turbochargers, model TA0411, installed. AD 2012-24-09 required removing certain HET turbochargers from service before further flight. This AD also requires removing certain HET turbochargers from service before further flight. This AD was prompted by a report that an additional engine, the CMI LTSIO-360- RB, has the affected HET turbochargers installed. 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.
(1) Comply with this AD within the compliance times specified, unless already done.
(2) After the effective date of this AD and before further flight, remove from service any turbocharger identified in Tables 1 and 2 of HET ASB No. 048, dated November 16, 2012.
After the effective date of this AD, do not return to service, and do not operate without a special flight permit, any engine with an HET turbocharger installed that is identified in Tables 1 and 2 of HET ASB No. 048, dated November 16, 2012.
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.
