ACTION: Final rule; request for comments.
AGENCY:

The FAA is superseding Airworthiness Directive AD 201816
10 which applied to certain GE Aviation Czech s.r.o. GEAC H80200 model turboprop engines. AD 20181610
required an adjustment of the engine push-pull control and replacement of the beta switch to prevent the propeller governor control from going to a negative thrust position. This AD
requires an initial inspection and adjustment of the engine push-pull

control and replacement of the beta switch. This AD also requires inspection and adjustment of the engine push-pull control after any maintenance, repair or modification that affects the push-pull control and installation of an improved push-pull control. This AD also expands the applicability to include GEAC H85
200 model turboprop engines with Avia Propeller AV725 propellers installed.
This AD was prompted by an accident involving an Aircraft Industries AI L
410 UVPE20 airplane caused by one propeller going to a negative thrust position during the landing approach.
The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective November 18, 2021.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD
as of November 18, 2021.

SUPPLEMENTARY INFORMATION:
Background The FAA issued AD 20181610, Amendment 3919350 83 FR 43742, August 28, 2018 AD 20181610, for certain GE Aviation Czech H80200
model turboprop engines. AD 201816
10 required replacement of the beta switch and adjustment of the engine push-pull control to prevent the propeller governor control from going to a negative thrust position. AD 201816
10 resulted from an accident involving an AI L 410 UVPE20 airplane caused by one propeller going to a negative thrust position during the landing approach. The FAA issued AD 2018
1610 to require engine modification to prevent asymmetric thrust. The unsafe condition, if not addressed, could result in failure of the beta switch, loss of engine thrust control, and reduced control of the airplane.
Actions Since AD 20181610 Was Issued Since the FAA issued AD 201816
10, the European Union Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Community, has issued EASA
AD 20200143, dated June 25, 2020, to address an unsafe condition for the specified products. The MCAI states:
In 2017, a fatal accident was reported of an L 410 UVPE20 aeroplane. The investigation determined that there was an annunciation of Beta mode on the right-hand engine, that the propeller went inadvertently beyond the fine pitch position and reached a negative thrust position, and that the pitch lock system did not intervene. The event occurred on approach at a speed and altitude which did not allow the flight crew to recover this control system malfunction.
This condition, if not corrected, could lead to reduced control or loss of control of the aeroplane.
To address this unsafe condition, GEAC
issued the SB, providing inspection and modification instructions, and EASA issued AD 20180075 to require a one-time inspection and adjustment of the engine push-pull control and replacement of the beta switch with an improved part.
Addressing the same unsafe condition at aeroplane level, EASA also issued AD 2018
0057, requiring modification of affected AI L
410 UVPE20 and L 410 UVPE20 CARGO
aeroplanes, if equipped with H80200
