Time Limits / Maintenance Checks — Airworthiness Limitations Section — Amendment
Summary
EASA Airworthiness Directive 2023-0184 is an amendment addressing the time limits and maintenance checks in the Airworthiness Limitations Section for Pilatus PC-12, PC-12/45, PC-12/47, and PC-12/47E aeroplanes. It mandates compliance with updated maintenance tasks and life limits as specified in the latest Pilatus PC-12 Aircraft Maintenance Manual Chapter 04-00-00. The directive ensures continued airworthiness by enforcing new and more restrictive maintenance requirements.
What Changed
EASA AD 2023-0184 supersedes previous directives and introduces new and more restrictive maintenance tasks and limitations, including new repetitive inspections of the main landing gear yoke fitting for aeroplanes with hydraulic landing gear. It updates the applicable Airworthiness Limitations Section to the latest revisions of the Pilatus PC-12 AMM documents. This amendment consolidates and replaces the requirements of AD 2008-0163 and AD 2022-0103.
Why It Matters
This directive is critical for operators and maintenance organizations to ensure compliance with the latest mandatory maintenance tasks and life limits, preventing unsafe conditions. It affects maintenance planning and scheduling by requiring incorporation of updated tasks and intervals into the Aircraft Maintenance Programme. Failure to comply could result in unsafe conditions and regulatory non-compliance, impacting aircraft availability and safety.
What To Do
Operators must replace components before exceeding life limits and perform all applicable maintenance tasks within specified thresholds and intervals as per the updated Airworthiness Limitations Section. Any discrepancies found during maintenance must be corrected within the compliance times specified or before next flight if unspecified. The Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the new limitations and tasks.
