To address this problem, you must do the following: Table 1.—Actions/Compliance/Procedures Actions Compliance Procedures (1) For Group 1 and Group 2 airplanes: Check the maintenance records to determine whether the brake caliper piston O-ring seals were replaced at the last annual or 100-hour inspection. Within 50 hours time-in-service (TIS) after November 17, 2006 (the effective date of this AD), unless already done No special procedures necessary to check the maintenance records. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may make this check. You must make an entry into the airplane records that shows compliance with this portion of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). (2) For Group 1 and Group 2 airplanes: If you find as a result of the check required by paragraph (e)(1) of this AD that there is no record of the replacement of brake caliper piston O-ring seals at the last annual or 100-hour inspection, then do the following: (i) Replace the O-ring seals with new O-ring seals or (ii) Replace old brake calipers with new brake calipers. Before further flight after the check required by paragraph (e)(1) of this AD For the replacement, follow the brake maintenance procedures in Section 32-42 of the SR20 or SR22 Aircraft Maintenance Manual. For the replacement of the new brake calipers, follow Cirrus Design Corporation Service Bulletin SB 2X-32-13 R1, Issued: December 15, 2005, Revised May 16, 2006. (3) For Group 3 and Group 4 airplanes: (i) Modify the main landing gear (MLG) wheel fairings to add temperature indicator sticker inspection holes and trim the wheel fairings to prevent them from holding fluids; and (ii) Install a temperature indicator sticker on the brake calipers. Do the modification within 50 hours TIS after November 17, 2006 (the effective date of this AD), unless already done. Do the temperature indicator sticker installation within 50 hours TIS after November 17, 2006 (the effective date of this AD), unless already done, and thereafter before further flight anytime you have the O-ring seals replaced due to overheating of the brake assembly (temperature indicator sticker turned black) Follow Cirrus Design Corporation Service Bulletin SB 2X-32-14 R1, Issued: January 18, 2006, Revised: February 17, 2006.

This AD results from several reports of airplanes that experienced brake fires and two airplanes that lost directional control. The actions specified in this AD are intended to detect, correct, and prevent overheating damage to the brake caliper piston O-ring seals, which could result in leakage of brake hydraulic fluid. Consequently, this could lead to the loss of braking with loss of airplane directional control or brake fire.
