Airworthiness Directive 2018-07-13
one-timeAirworthiness Directives; Textron Aviation Inc. Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Models 510, 680, and 680A airplanes equipped with certain part number brake assemblies. This AD was prompted by a report that brake pad wear indicator pins were set incorrectly, which could lead to brake pad wear beyond the acceptable limits without indication. This AD requires inspection of the brake pad wear indicator pins and replacement of the brake assembly if any pin is set incorrectly. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2018-07-13 applies to
Applies only to airplanes equipped with a specific brake assembly bearing a serial number listed in the referenced UTC Aerospace Systems service bulletins: Model 510 S/N -0001 through -0479 w/ brake P/N 2-1706-1 (UTC SB 2-1706-1-32-1 Rev 1); Model 680 S/N -0001 through -0349 and -0501 through -0570 w/ brake P/N 2-1675-1 (UTC SB 2-1675-32-2 Rev 1); Model 680A S/N -0003 through -0069 and -0071 through -0089 w/ brake P/N 2-1675-1 (UTC SB 2-1675-32-2 Rev 1).
Whether AD 2018-07-13 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
