| 2016-17159 | Airworthiness Directives; International Aero Engines AG Turbofan Engines | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527- A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5, and V2531-E5 turbofan engines. This proposed AD was prompted by nine in- flight shutdowns that resulted from premature failure of the No. 3 bearing. This proposed AD would require initial and repetitive inspections of the master magnetic chip detector (MMCD) and, if metallic debris is found, further actions depending on the type of metallic debris. This proposed AD would also require removal of the No. 3 bearing from service at the next engine shop visit. We are proposing this AD to prevent failure of the No. 3 bearing, failure of one or more engines, loss of thrust control, and loss of the airplane. | 2016-07-21 | 2016 | 7 | https://www.federalregister.gov/documents/2016/07/21/2016-17159/airworthiness-directives-international-aero-engines-ag-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2016-07-21/pdf/2016-17159.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527- A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5, and V2531-E5 turbofan engines.
