What to do
Operators of Textron Aviation Models 510, 680, and 680A with the specified brake assemblies must inspect the brake pad wear indicator pins and replace the brake assembly if any pin is found incorrectly set. Compliance with this directive is required by May 15, 2018. Service information from Textron Aviation and UTC Aerospace Systems should be used to perform the inspections and replacements.
Summary
The Federal Aviation Administration's Airworthiness Directive 2018-07-13 addresses certain Textron Aviation Inc. Models 510, 680, and 680A airplanes equipped with specific brake assemblies, part numbers 2-1706-1 and 2-1675-1. This directive mandates inspection and potential replacement of brake pad wear indicator pins to prevent undetected brake pad wear beyond acceptable limits.
What changed
This new airworthiness directive introduces mandatory inspections of brake pad wear indicator pins on affected Textron Aviation airplane models and requires replacement of the brake assembly if any pin is incorrectly set. It responds to reports of improperly set wear indicator pins that could lead to loss of braking effectiveness and runway excursions.
Why it matters
This directive is critical for aviation professionals because improperly set brake wear indicator pins can cause brake pads to wear excessively without warning, compromising aircraft safety. Operators, maintenance organizations, and compliance teams must ensure inspections and replacements are performed to maintain braking performance and regulatory compliance.
