2015-28898 Airworthiness Directives; General Electric Company Turbofan Engines Proposed Rule We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80E1 turbofan engines with rotating compressor discharge pressure (CDP) seal, part number (P/N) 1669M73P02, installed. This proposed AD was prompted by reports from the manufacturer of cracks in the teeth of two rotating CDP seals found during engine shop visits. This proposed AD would require stripping of the coating, inspecting, and recoating the teeth of the affected rotating CDP seals. We are proposing this AD to prevent cracking of the CDP seal teeth, which can lead to uncontained part release, damage to the engine, and damage to the airplane. 2015-11-17 2015 11 https://www.federalregister.gov/documents/2015/11/17/2015-28898/airworthiness-directives-general-electric-company-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2015-11-17/pdf/2015-28898.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80E1 turbofan engines with rotating compressor discharge pressure (CDP) seal, part number (P/N) 1669M73P02, installed.
