Airworthiness Directive 06-3616
recurringAirworthiness Directives; General Electric Company Aircraft Engines (GEAE) CT7-8A Turboshaft Engines
What this AD requires
This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (EAD) 2006-06-51 that we sent previously to all known U.S. owners and operators of GEAE CT7-8A turboshaft engines installed on Sikorsky S92 helicopters. This AD requires initial and repetitive inspections of the electrical chip detectors for the No. 3 bearing. This AD results from two failures of the No. 3 bearing in GEAE CT7-8A engines. We are issuing this AD to prevent failures of the No. 3 bearings and possible dual in-flight shutdowns of the engines.
Which aircraft AD 06-3616 applies to
Applies only to the specific serial-numbered engines listed (installed on Sikorsky S-92 helicopters); the range '947238 through 9472268' is reproduced as printed in the source text (likely a typographical rendering of 947268).
Whether AD 06-3616 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.
