| 2012-28638 | Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines | Rule | We are adopting a new airworthiness directive (AD) for certain serial number (S/N) Rolls-Royce Deutschland Ltd & Co KG (RRD) TAY 620- 15 turbofan engines. This AD requires initial and repetitive general inspections and ultrasonic inspections (UI) of low-pressure compressor (LPC) fan blades for cracks. If any fan blade is found cracked, this AD requires replacement of the LPC fan blade set and the LPC fan disc. This AD was prompted by a report of an LPC fan blade separation. We are issuing this AD to detect cracks in the LPC fan blades, which could lead to uncontained failure of the LPC fan blades and LPC fan disc, and damage to the airplane. | 2012-11-29 | 2012 | 11 | https://www.federalregister.gov/documents/2012/11/29/2012-28638/airworthiness-directives-rolls-royce-deutschland-ltd-and-co-kg-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2012-11-29/pdf/2012-28638.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting a new airworthiness directive (AD) for certain serial number (S/N) Rolls-Royce Deutschland Ltd & Co KG (RRD) TAY 620- 15 turbofan engines.
