Airworthiness Directive E7-16554
one-timeAirworthiness Directives; General Electric Company CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 Turbofan Engines
What this AD requires
The FAA is revising an existing airworthiness directive (AD) for General Electric Company (GE) CF34-1A, -3A, -3A1, -3A2, -3B, and - 3B1 turbofan engines. That AD currently requires a one-time inspection of certain fan disks for electrical arc-out indications, replacing fan disks with electrical arc-out indications, and reducing the life limit of certain fan disks. This AD results from a comment received on AD 2007-07-07, and from recently issued revisions to the applicable GE Alert Service Bulletins (ASBs). We are issuing this AD to prevent an uncontained fan disk failure and airplane damage.
Which aircraft AD E7-16554 applies to
Applies only to engines with a fan disk bearing one of the listed part numbers installed.
Whether AD E7-16554 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.
