AD/B737/188 Amdt 1 - Main Wheel Well Electrical Connectors - CANCELLED

This document officially cancels a previous aviation safety rule that applied to Boeing 737 aircraft.

What it does

• Cancels the old directive: It formally revokes Airworthiness Directive AD/B737/188, which previously required specific maintenance actions for electrical connectors located in the main wheel wells of Boeing 737 planes.
• Replaced by a newer rule: The old directive is no longer in force because a more comprehensive safety directive (AD/B737/297) now applies instead.
• Why the change: The replacement rule introduces extended repetitive inspections and addresses an additional de-icing agent that could damage the electrical connectors, ensuring safer maintenance standards.

Who it affects

• Owners, operators, and maintenance engineers of Boeing 737 series aircraft registered in Australia.

Why it matters This cancellation ensures aircraft operators follow the most up-to-date safety inspection procedures for wheel well electrical systems, keeping Australian standards aligned with United States Federal Aviation Administration requirements.
