## Abstract

The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. This AD requires a onetime inspection of the Independent Overspeed Protection (IOP) unit, part number (P/N) 112E9321G2, for 19 specific serial numbers (SNs), and removal from service of those units. This AD results from a report that incorrect capacitors were installed in 19 IOP units. The incorrect capacitor in the IOP unit can lead to an inadvertent IOP command resulting in an in-flight engine shutdown. We are issuing this AD to prevent inadvertent dual-engine in-flight shutdown.
