SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20201307, Amendment 3921152 85 FR 38312, June 26, 2020, AD 20201307. AD
20201307 applied to all RRD Trent 1000D2, Trent 1000J2, and Trent 1000K2 model turbofan engines with fuel pump, part number G5030FPU01, installed. The NPRM published in the Federal Register on March 30, 2021 86
FR 16548. The NPRM was prompted by the manufacturers investigation into an unexpected reduction in fuel pump performance in certain high life fuel pumps and life-related wear-out of the internal components and subsequent determination that an additional partnumbered fuel pump is subject to this same unsafe condition. In the NPRM, the FAA proposed to retain all the requirements of AD 20201307. In the NPRM, the FAA also proposed to add an additional part-numbered fuel pump and additional Trent 1000 model turbofan engines on which this fuel pump is installed to the applicability. In the NPRM, the FAA also proposed to require new and reduced life limits for certain part-numbered fuel pumps,
