EASA AD 26-021 — Electrical System Installation — Inspections
Summary
EASA Airworthiness Directive 26-021 is a proposed directive addressing electrical system installation inspections on Airbus Defence and Space C-295 aeroplanes, specifically serial numbers 188, 189, and 191. It mandates repetitive detailed visual inspections of the harness protection adjacent to frame 30 between stringers 6 and 7 on the right-hand side. The directive aims to ensure continued airworthiness by preventing potential system failures or cabin fires related to wiring issues.
What Changed
This new proposed Airworthiness Directive introduces mandatory repetitive inspections of a specific harness protection area on certain C-295 aircraft, which was previously not included in the published Airworthiness Limitations Section. It requires inspections within 50 flight hours after the effective date and at intervals not exceeding 350 flight hours thereafter. If discrepancies are found, the affected part must be replaced before further flight.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent electrical system failures and potential cabin fires caused by undetected wiring issues. Compliance ensures the safety and reliability of affected C-295 aeroplanes and aligns maintenance practices with certification requirements. Failure to comply could result in unsafe conditions and regulatory non-conformance.
What To Do
Operators of Airbus Defence and Space C-295 aeroplanes with serial numbers 188, 189, and 191 must perform detailed visual inspections of the specified harness protection within 50 flight hours after the directive's effective date and repeat these inspections every 350 flight hours. Any discrepancies found during inspections require immediate replacement of the affected part before the next flight. Comments on the proposed directive must be submitted by 2 March 2026.
