What to do
Operators of affected ATR 42-500 and ATR 72-212A aeroplanes must inspect the electrical harness brackets and wire bundles on both left and right sides within 6 months or 500 flight hours, whichever occurs first, from the effective date of this AD. Any discrepancies found must be corrected before the next flight following the instructions in the applicable ATR service bulletins. Compliance with the updated service bulletin revisions is required.
Summary
EASA Airworthiness Directive 2018-0105 is an official safety directive addressing inspection requirements for electrical harness brackets and wire bundles on ATR 42 and ATR 72 aeroplanes. It applies specifically to certain manufacturer serial numbers of ATR 42-500 and ATR 72-212A models. The directive mandates inspections to detect missing brackets and potential wire damage that could lead to system failures.
What changed
This directive supersedes EASA AD 2017-0118 and expands the applicability to include additional ATR 42 and ATR 72 aeroplanes not previously covered. It retains the inspection and corrective action requirements from the previous AD but adds new serial numbers to the affected groups and updates the service bulletin revisions to be used for compliance.
Why it matters
This directive is critical for aviation professionals because missing electrical harness brackets can cause wire chafing and damage, potentially leading to multiple system failures and reduced aircraft control. Operators and maintenance teams must ensure compliance to prevent safety risks and avoid operational disruptions due to electrical system faults.
