Life Limited Part Services
Fierbois Engine Services provides focused aviation engine lifecycle checks for all major commercial turbine engines, with particular emphasis on the diligent management of life limited parts. LLPs play a critical role in ensuring operational integrity and must never be compromised. We undertake rigorous, back-to-birth traceability reviews on every LLP, scrutinising logbooks and documentation to guarantee full compliance with regulatory demands set by both the FAA and EASA.
Our skilled team verifies each part's service record and operational history, to forecast future maintenance events and establish the remaining service life of the engine. Salvaging life limited parts with documented time remaining is a core element of our approach, helping clients realise asset value while maintaining uncompromising safety standards. By managing this process diligently, we give clients the reassurance and peace of mind that comes with knowing their engines are in professional hands.
Documentation and Oversight
Effective traceability and documentation systems are at the heart of our aviation engine lifecycle management work. Fierbois Engine Services catalogues detailed records required for compliance and operational excellence. All documentation relating to Regulatory Airworthiness Directives and Service Bulletins are reviewed and audited. For critical parts, including LLPs, documentation is critically evaluated and presented to maximise an aviation transaction. Whether for continued service, lease transaction or teardown, our teams prepare and manage client records to strict regulatory standards.
We work closely with both UK and Ireland-based operators, as well as international clients, so that regulatory documentation meets the demands of both FAA and EASA authorities. Our oversight covers diagnostics, careful reporting, and archiving, ensuring every LLP's history is easily traceable and always up to date. With our robust transition support and documentation management, your engine assets are always optimised for continued use or seamless handover at lease return.

Frequently Asked Questions
What are aviation engine lifecycle checks?
Aviation engine lifecycle checks involve detailed inspections, documentation reviews, and compliance verification for all engine components, especially life limited parts, to ensure safety and regulatory compliance.
Which parts are life-limited and require checks?
Life limited parts (LLPs) include components such as discs, shafts, and spools inside turbine engines, each with a set maximum life defined by hours or cycles. Regular lifecycle checks ensure safe continued use or timely replacement.
What documentation is required for LLP management?
LLP management demands thorough back-to-birth traceability, with all records, reports, service logs and compliance certificates meeting FAA and EASA standards to guarantee safety and asset value.
What engine types do you specialise in for lifecycle checks?
We specialise in V2500-A5, CFM56-3/5B/7B, PW4000, Trent 700/800, and GE90 engine series, providing complete LLP services for each model.
Why is back-to-birth traceability important for LLPs?
Back-to-birth traceability ensures the full history of each life limited part is documented, verifying its safety, compliance, and eligibility for reuse or installation.
