Airworthiness Directive 2022-02-03
one-timeAirworthiness Directives; CFM International, S.A. Turbofan Engines
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2013-26-01 for all CFM International, S.A. (CFM) CFM56-3 and CFM56-7B model turbofan engines with a certain accessory gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in the handcranking pad. AD 2013-26-01 required an independent inspection to verify re-installation of the handcranking pad cover after removal of the pad cover for maintenance. This AD was prompted by a dual engine loss of oil event and 42 prior events of total loss of engine oil during flight. This AD requires independent inspection to verify re-installation of the AGB handcranking pad cover after maintenance. This AD also requires the replacement of the affected AGB as a terminating action to the inspection requirement. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-02-03 applies to
Applies only with an installed accessory gearbox (AGB) assembly of a specific part number depending on model: (1) CFM56-3/-3B/-3C: AGB P/N 335-300-103-0, -105-0, -106-0, -107-0, -108-0, -109-0, or -110-0. (2) CFM56-7B20 through CFM56-7B27/B3 variants: AGB P/N 340-046-503-0, -504-0, or -505-0. (3) CFM56-7B27A, CFM56-7B27A/3, or CFM56-7B27AE: AGB P/N 340-188-601-0, -603-0, or -605-0.
Whether AD 2022-02-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
