| 00-11178 | Airworthiness Directives; General Electric Aircraft Engines CT7 Series Turboprop Engines | Proposed Rule | This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain General Electric Aircraft Engines (GEAE) CT7 series turboprop engines. This proposal would require initial and repetitive inspections of the propeller gearbox (PGB) oil filter impending bypass button (IBB) for extension (popping). This proposal would also require follow-on inspections, maintenance, and replacement actions if the PGB oil filter IBB is popped; and if necessary, replacement of the PGB with a serviceable PGB. In addition, this proposal would require a one-time removal of possibly improperly hardened PGB input pinions and replacement with PGB input pinions that were manufactured using the proper hardening process as terminating action to the repetitive inspections. This proposal is prompted by reports of improperly hardened PGB input pinions. The actions specified by the proposed AD are intended to prevent PGB input pinion failure, which could result in PGB failure and an in-flight engine shutdown. | 2000-05-04 | 2000 | 5 | https://www.federalregister.gov/documents/2000/05/04/00-11178/airworthiness-directives-general-electric-aircraft-engines-ct7-series-turboprop-engines | https://www.govinfo.gov/content/pkg/FR-2000-05-04/pdf/00-11178.pdf | Transportation Department; Federal Aviation Administration | 492,159 | This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain General Electric Aircraft Engines (GEAE) CT7 series turboprop engines.
