BN-2, BN-2A, BN-2B, BN-2T Piper PA-24-400, PA-30, PA-32-260, PA-32-300, PA-34-200, PA-39 In addition, products may have been used on kit planes, homebuilt aircraft or by float manufacturers. REASON: Parker Hannifin has received reports of surface discontinuities in the brake disc cup wall adjacent to the mounting flange on P/N 164-02201 brake disc that have been removed from service. The returned products contain through wall discontinuities, missing material, and / or complete separation of the brake disc cup mounting surface from the brake disc cup wall and flange. (Reference Figure 1) It is required that in service products containing indications be removed from service. Continued use of a product with indications could result in the loss of directional control or brake effectiveness during taxi. By their very nature, brake discs are wear components with service life being influenced by factors such as; aggressive braking, improper wheel tie bolt torque, landing gear vibration, corrosion and heat. All of which can cause a product’s removal from service. Performing maintenance and regular inspections of wheel and brake components in accordance with the Component Maintenance Manual will enhance the product’s useful service life. DESCRIPTION; This document provides the necessary inspection instructions for in service 164-02201 brake discs. COMPLIANCE: Mandatory- Perform accomplishment instructions as outlined on pages 2 and 3. APPROVAL: The contents of this Service Bulletin are FAA DER approved.

In the event that a brake disc has crack like indications, it must be replaced or more thoroughly evaluated using dye penetrant and or magnetic particle inspection techniques. These inspection techniques are more conclusive by the removal of any protective primers and paints. 4) Brake discs that are determined to contain cracks, worn below minimum flange thickness, elongated bolt holes, excessively coned or corroded must be replaced.
