Airworthiness Directive · Amendment 39-14787 · Cirrus Design Corporation Models SR20 and SR22 Airplanes
Cirrus Design Corporation Models SR20 and SR22 Airplanes
This AD applies to the following airplane models and serial numbers (S/N) that are certificated in any category:
(1) Group 1: Model SR20 Airplanes, S/N 1005 through 1600.
(2) Group 2: Model SR22 Airplanes, S/N 0002 through 1739.
(3) Group 3: Model SR20 Airplanes, S/N 1005 through 1592.
(4) Group 4: Model SR22 Airplanes, S/N 0002 through 1727.
The FAA adopts a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to check the maintenance records to determine whether the brake caliper piston O-ring seals were replaced at the last annual or 100-hour inspection. If the O-rings were not replaced, this AD requires you to replace the O-ring seals with new seals or replace brake calipers. This AD also requires you to modify the main landing gear wheel fairings to add temperature indicator sticker inspection holes, trim the wheel fairings to prevent them from holding fluids, install temperature indicator stickers on the brake calipers, and insert Revision A6 (with revised preflight walk-around, a limitation on the engine speed used to taxi, and brake inspection/servicing intervals) into the Pilot's Operating Handbook (POH). This AD results from several reports of airplanes experiencing brake fires and two airplanes losing directional control. We are issuing this AD 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.
To address this problem, you must do the following:
| 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. |
| (4) For all airplanes: Insert the appropriate Revision A6 part number (P/N) into the Pilot's Operating Handbook (POH), as presented in TABLE 2.—REVISION A6 TO THE PILOT'S OPERATING HANDBOOK, in paragraph (f) of this AD. | Within 50 hours TIS after November 17, 2006 (the effective date of this AD), unless already done | 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 insert the information into the POH as specified in paragraph (e)(4) of this AD. Make an entry into the airplane maintenance records showing compliance with this portion of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). |
| (5) For Group 3 and Group 4 airplanes: (i) Do not install any MLG fairings without also doing the modifications required by paragraph (e)(3)(i) of this AD; and (ii) Do not replace any brake calipers without also installing the temperature indicator sticker required by paragraph (e)(3)(ii) of this AD. | As of November 17, 2006 (the effective date of this AD) | Follow Cirrus Design Corporation Service Bulletin SB 2X-32-14 R1, Issued: January 18, 2006, Revised: February 17, 2006. |
(f) The following table specifies the POH Revision A6 part number as required in paragraph (e)(4) of this AD:
| Affected airplanes | Model SR20 or SR22 airplane POH P/N | Date FAA-approved |
|---|---|---|
| (1) Model SR20, S/N 1148 through 1267 | 11934-002 | January 18, 2006. |
| (2) Model SR20, S/N 1005 through 1147 that have the 3,000-pound gross weight modification following Cirrus Design Corporation Service Bulletin SB 20-01-00, Issued: February 25, 2003 | 11934-002 | January 18, 2006. |
| (3) SR20, S/N 1268 through 1739 | 11934-003 | January 18, 2006. |
| (4) SR22, S/N 002 through 1739 | 13772-001 | January 18, 2006. |
