AD: CFM International, S.A. Turbofan Engines

AD 2022-02-03 Applies To CFM International, S.A. CFM56-3 and CFM56-7B Model Turbofan Engines With Certain AGB

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register.

The AD applies to CFM International, S.A. CFM56-3 and CFM56-7B model turbofan engines with certain accessory gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in the handcranking pad. As published, the part numbers (P/Ns) listed in paragraph (i)(2)(i) are incorrect. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is publishing the entire rule in the Federal Register. This correction is effective March 22, 2022. The effective date of AD 2022-02-03 remains March 22, 2022.

Supplementary Information: AD 2022-02-03, 39-21961 (87 FR 8402, February 15, 2022) (AD 2022-02-03), requires independent inspection to verify re-installation of the AGB handcranking pad cover after maintenance. AD 2022-02-03 also requires the replacement of the affected AGB with a part eligible for installation as a terminating action to the inspection requirement.

Need for the Correction: As published, the P/Ns listed in paragraph (i)(2)(i) of the AD, which defines a part eligible for installation, are incorrect. The P/Ns were incorrectly listed as 340-046-503-0, 340-046-504-0, and 340-046-505-0. The correct P/Ns are 335-300-103-0, 335-300-105-0, 335-300-106-0, 335-300-107-0, 335-300-108-0, 335-300-109-0, and 335-300-110-0.

Although no other part of the preamble or regulatory information has been corrected, for clarity, the FAA is publishing the entire rule in the Federal Register.

The effective date of this AD remains March 22, 2022.
