What to do
Operators must perform initial and repetitive borescope inspections of affected IPC Rotor 1 and Rotor 2 blades and shaft according to specified compliance times, including inspections following asymmetric power operations. Engines modified with RR mod 72-J941 are exempt from these inspections but must apply the modification service bulletin. Compliance deadlines vary by engine group and operational status, with initial inspections required within 80 flight cycles or as specified by engine health monitoring alerts.
Summary
EASA Airworthiness Directive 2018-0084R2 is a regulatory update addressing safety concerns for Rolls-Royce Trent 1000 series engines installed on Boeing 787 aircraft. It mandates repetitive inspections of intermediate pressure compressor (IPC) Rotor 1 and Rotor 2 blades and shaft to detect cracks that could lead to in-flight blade release. The directive excludes engines modified with RR mod 72-J941 and introduces a modification service bulletin as terminating action for inspections.
What changed
This revision reduces the applicability by excluding Trent 1000 engines that have incorporated Rolls-Royce modification 72-J941. It also introduces Service Bulletin TRENT 1000 72-J941 as a terminating action for the repetitive inspections previously required. The directive consolidates and updates inspection instructions based on the latest Rolls-Royce service bulletins.
Why it matters
The directive is critical for operators and maintenance organizations to prevent potential in-flight failures caused by cracked IPC blades, which could compromise aircraft control. Compliance ensures continued airworthiness and safety of Boeing 787 aircraft powered by affected Trent 1000 engines. It also impacts ETOPS operations by imposing specific inspection requirements to maintain operational reliability.
