Airworthiness Directive · Amendment 39-12098 · Rolls-Royce Deutschland GmbH (Formerly BMW Rolls-Royce GmbH) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
Rolls-Royce Deutschland GmbH (Formerly BMW Rolls-Royce GmbH) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
This airworthiness directive (AD) is applicable to certain Rolls-Royce Deutschland GmbH (formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines that are listed by serial number in Table 1 and Table 2 of this AD, and that have a high pressure turbine (HPT) stage 1 disk, part number (P/N) BRH20009, BRH20010, BRH12167, BRH12168, BRH12466, or BRH12467 with a SN that is listed in Table 1; or a stage 2 disk, P/N's BRH19349 or BRH19350 with a SN that is listed in Table 2. These engines are installed on but not limited to McDonnell Douglas Corporation 717 airplanes.
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2000-25-51 that was sent previously to all known U.S. owners and operators of Rolls-Royce Deutschland GmbH (formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. This action requires that certain high pressure turbine (HPT) stage 1 disks, part numbers (P/N's) BRH20009, BRH20010, BRH12167, BRH12168, BRH12466, and BRH12467; and stage 2 disks, P/N's BRH19349 and BRH19350, be removed before exceeding the new reduced cyclic limit, and replaced with a serviceable disk. This amendment is prompted by a reduction of the life limit for several high pressure turbine (HPT) stage 1 and stage 2 disks. The actions specified in this AD are intended to prevent an uncontained failure of the HPT stage 1 or stage 2 disk due to exceeded life-cycle limits.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
