What to do
Operators of Boeing 787 aircraft with Rolls-Royce Trent 1000 engines must inspect affected low pressure compressor blades before the compliance dates specified in the Rolls-Royce NMSB or within 30 days after 3 November 2023, whichever is later. Any blades exceeding acceptance criteria must be replaced with serviceable parts. Installation of affected parts is only permitted if they are serviceable as defined by the directive. Compliance with these actions is mandatory from 1 December 2023.
Summary
EASA Airworthiness Directive 2023-0201 is an airworthiness directive addressing Rolls-Royce Trent 1000 series engines installed on Boeing 787 aircraft. It mandates inspection and possible replacement of low pressure compressor blades with specific part and serial numbers to prevent cracking. The directive ensures continued airworthiness by requiring compliance with Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 72-AK965 Revision 2.
What changed
EASA AD 2023-0201 supersedes the previous AD 2023-0185 by expanding the population of affected low pressure compressor blades at risk of cracking. It retains the inspection and replacement requirements but includes additional affected parts identified by Rolls-Royce. The directive also updates compliance instructions referencing the latest revision of the Rolls-Royce NMSB.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk of uncontained engine failure due to cracked compressor blades, which could lead to engine shutdown and potential damage to the aircraft. Operators and maintenance organizations must ensure timely inspections and replacements to maintain regulatory compliance and flight safety. Failure to comply could result in grounding of affected aircraft and increased operational risk.
