Thielert Aircraft Engines GmbH Reciprocating Engines
This AD applies to all Thielert Aircraft Engines GmbH TAE 125-02-99 and TAE-125-02-114 reciprocating engines with friction disk, part number (P/N) 05-7211-K010201, installed.
We are adopting a new airworthiness directive (AD) for all Thielert Aircraft Engines GmbH (TAE) TAE 125-02-99 and TAE 125-02-114 reciprocating engines. This AD was prompted by in-flight engine shutdown incidents reported on airplanes equipped with TAE 125 engines. We are issuing this AD to prevent in- flight engine shutdown, which could result in loss of control of the airplane.
Unless already done, do the following actions.
For TAE 125-02-99 engines, P/Ns 05-7200-K000201; 05-7200-K000701; 05-7200-K000101; 05-7200-K000901; 05-7200-K001101; and 05-7200-K001301; and TAE 125-02-114 engines, P/Ns 05-7200-K000501; 05-7200-K000801; and 05-7200-K001401, remove friction disk, P/N 05-7211-K010201, within 100 flight hours (FH) time-since-new (TSN) on the clutch or within 10 FH time-in-service (TIS) after the effective date of this AD, whichever is later.
For TAE 125-02-99 engines, P/N 05-7200-K000301, installed on multiengine aircraft, remove friction disk, P/N 05-7211-K010201, on one engine within 100 FH TSN on the clutch or within 10 FH TIS after the effective date of this AD, whichever is later. Remove friction disk, P/N 05-7211-K010201, from the other engine within 300 FH TSN on the clutch or within 10 FH TIS after the effective date of this AD, whichever is later.
After the effective date of this AD:
(1) Do not install any friction disk, P/N 05-7211-K010201, into any engine.
(2) Do not install any TAE 125-02-99 engine, P/N 05-7200-K000201, 05-7200-K000301, or 05-7200-K000701, or TAE 125-02-114 engine, P/N 05-7200-K00801 or 05-7200-K00501, that has a friction disk, P/N 05-7211-K010201 installed, onto any airplane.
Do not operate any multi-engine aircraft after 300 FH TSN on the clutch or 10 FH TIS after the effective date of this AD, whichever is later, which has installed a friction disk, P/N 05-7211-K010201.
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.
