| 2010-32156 | Airworthiness Directives; General Electric Company GE90-76B; GE90-77B; GE90-85B; GE90-90B; and GE90-94B Turbofan Engines | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require initial and repetitive fluorescent penetrant inspections (FPIs) and eddy current inspections (ECIs) of the high-pressure compressor rotor (HPCR) 8-10 stage spool, part numbers (P/Ns) 1844M90G01 and 1844M90G02, for cracks between the 9-10 stages, at each piece-part exposure. This proposed AD was prompted by cracks discovered on one HPCR 8-10 spool between the 9- 10 stages in the weld joint. We are proposing this AD to prevent failure of the HPCR 8-10 stage spool, uncontained engine failure, and damage to the airplane. | 2010-12-22 | 2010 | 12 | https://www.federalregister.gov/documents/2010/12/22/2010-32156/airworthiness-directives-general-electric-company-ge90-76b-ge90-77b-ge90-85b-ge90-90b-and-ge90-94b | https://www.govinfo.gov/content/pkg/FR-2010-12-22/pdf/2010-32156.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for the products listed above.
