Airworthiness Directive 2013-02-02
one-timeAirworthiness Directives; CFM International, S.A. Turbofan Engines Modified by Supplemental Type Certificate SE00034EN
What this AD requires
We are adopting a new airworthiness directive (AD) for CFM International, S.A. CFM56-3, CFM56-3B, and CFM56-3C turbofan engines. This AD requires removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. This AD was prompted by a report of a forging process error during manufacture of these HPT disks. We are issuing this AD to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane.
Which aircraft AD 2013-02-02 applies to
Applies only to engines modified by Supplemental Type Certificate SE00034EN with a high-pressure turbine (HPT) disk, P/N 880026, bearing one of the listed serial numbers, installed.
Whether AD 2013-02-02 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.
