Airworthiness Directive · Amendment 39-13594 · Cessna Model 500, 501, 550, and 551 Airplanes
Cessna Model 500, 501, 550, and 551 Airplanes
Model 500 and 501 airplanes, serial numbers 0001 through 0689 inclusive, and Model 550 and 551 airplanes, serial numbers 0002 through 0733 inclusive; certificated in any category; equipped with BFGoodrich brake assembly part number (P/N) 2-1528-6 or 2-1530-4.
This document corrects information in an existing airworthiness directive (AD) that applies to certain Cessna Model 500, 501, 550, and 551 airplanes. That AD currently requires a one-time inspection of the brake stator disks to determine to what change level they have been modified (if any), and related investigative and corrective actions if necessary. That AD also requires that the existing markings on the piston housing of certain brake assemblies be eliminated. This document corrects the compliance time for the inspection for cracked or broken stator disks on certain airplanes. This correction is necessary to ensure that affected airplanes are given sufficient time to comply with the requirements of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
