Airworthiness Directive 2001-10-03
one-timeAirworthiness Directives; General Electric Company CF34 Series Turbofan Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF34-1A, -3A, -3A1, - 3A2, -3B, and -3B1 turbofan engines. This action requires a one-time inspection, and if necessary replacement of certain fan disks for electrical arc-out indications, and assigns a reduction in the life limit of certain fan disks. This amendment is prompted by a report of a crack that was found during a visual inspection as part of routine engine maintenance. The actions specified in this AD are intended to prevent rupture of the fan disk due to cracks that initiate at an electrical arc-out, which could result in an uncontained failure of the engine.
Which aircraft AD 2001-10-03 applies to
Requires removal (based on cycles-since-new) or inspection of fan disks listed by P/N with specific serial numbers in AD Table 1, due to risk of rupture from electrical arc-out-initiated cracking, per GE Alert SB CF34-BJ 72-A0088; fan disk serials listed individually (partial list shown, table truncated in source), to prevent uncontained engine failure.
Whether AD 2001-10-03 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.
