What to do
Affected operators must replace components before exceeding new life limits and perform all maintenance tasks within specified intervals starting from 17 July 2026. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate the updated Airworthiness Limitations Section. Any discrepancies found during inspections must be corrected before the next flight, following GEAC maintenance documentation or approved alternative instructions.
Summary
EASA Airworthiness Directive 2026-0123 is an amendment concerning time limits and maintenance checks in the Airworthiness Limitations Section for GE Aviation Czech H75, H80, and H85 engine models. This directive applies to these engines installed on aircraft such as the Aircraft Industries L410-UVP-E20, L410-NG, Do 28 series, Thrush S-2R series, and Viking Air DHC-3 Otter. It mandates compliance with updated maintenance tasks and life limits to ensure continued airworthiness.
What changed
EASA Airworthiness Directive 2026-0123 supersedes the previous AD 2023-0021 and introduces new and more restrictive maintenance tasks and life limits as specified in the latest revision of the GEAC Engine Maintenance Manual No. 0983402 Revision 30. It also requires compliance with specific GEAC Alert Service Bulletins that provide instructions for evaluating accumulated life of critical engine parts. The directive updates the Aircraft Maintenance Programme to incorporate these new requirements.
Why it matters
This directive is critical for aviation professionals because it ensures the continued airworthiness and safety of aircraft powered by GEAC H series engines by enforcing updated maintenance standards. Operators and maintenance organizations must adhere to these revised life limits and inspection intervals to prevent unsafe conditions. Compliance helps avoid unplanned engine failures and supports regulatory adherence under EU aviation safety regulations.
