What to do
Operators must remove affected Trent 1000 engines from service before exceeding specified IPTB life limits or within 30 days of the directive's effective date, whichever is later. After removal, the IPTB must be replaced following the instructions in the referenced Rolls-Royce service documents. Engines currently in shop must also have IPTB replaced before release to service. Compliance with cyclic life limits for service used material IPTB is mandatory, and modification with approved service bulletins constitutes terminating action.
Summary
EASA Airworthiness Directive 2019-0135 is an airworthiness directive addressing Rolls-Royce Trent 1000 engine models installed primarily on Boeing 787 aircraft. It mandates the removal and replacement of intermediate pressure turbine blades (IPTB) due to reported cracking caused by sulphidation corrosion, which poses a risk of engine in-flight shutdown. The directive applies to multiple Trent 1000 variants and specifies affected part numbers and serial numbers as listed in the referenced Rolls-Royce service documents.
What changed
EASA Airworthiness Directive 2019-0135 supersedes the previous AD 2018-0257 and expands applicability to include Trent 1000 TEN engine models. It retains the requirement for removal and replacement of affected IPTB and introduces updated cyclic life limits for engines with service used material IPTB installed. The directive also references updated Rolls-Royce service bulletins and non-modification service bulletins for compliance procedures.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to engine failure and reduced aircraft control. Operators and maintenance organizations must ensure compliance to prevent in-flight shutdowns and maintain airworthiness. The directive also affects maintenance planning and parts management due to the required blade replacements and cyclic life monitoring.
