Airworthiness Directive · Amendment 39-16136 · Ice and rain protection
Cirrus Design Corporation Model SR22 Airplanes
This AD applies to Model SR22 airplanes; serial numbers 3409, 3411 through 3430, 3432 through 3441, 3443 through 3450, 3455 through 3465, 3467, 3468, 3470 through 3472, 3485, 3486, 3488, 3489, 3491 through 3493, 3495 through 3500, 3504, 3505, 3512, 3513, 3517, 3524, 3525, 3528, and 3546 that are:
(1) Equipped with an anti-ice system approved for flight into known icing; and
(2) Certificated in any category.
We are adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation Model SR22 airplanes equipped with an anti- ice system approved for flight into known icing. This AD requires you to inspect the compression fittings on the anti-ice fluid distribution lines for proper installation and repair any fittings that were not properly installed. This AD results from the manufacturer finding some anti-ice fluid distribution lines where the compression fittings were not properly installed. We are issuing this AD to detect and correct anti-ice fluid distribution lines with improperly installed compression fittings, which could result in anti-ice fluid distribution line separation. A line separation could result in a total loss of ice protection fluid supply to the protected surfaces, which would allow ice to build on the airplane and degrade the handling qualities and performance.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Fabricate a placard (using at least 1/8 -inch letters) with the following words and install a placard on the instrument panel within the pilot's clear view: “FLIGHT INTO KNOWN OR FORECAST ICING PROHIBITED.” | Before further flight after December 21, 2009 (the effective date of this AD), unless the inspection requirement of paragraph (f)(2) has already been done. | Not Applicable. |
| (2) Inspect and repair as necessary the anti-ice fluid line compression fittings. Accomplishment of all of the actions specified in Cirrus SR22 service bulletin SB 2X-30-08, dated November 9, 2009, terminates the placard requirements specified in paragraph (f)(1) of this AD. | (i) Inspect at the next scheduled inspection after December 21, 2009 (the effective date of this AD) or within the next 100 hours time-in-service after December 21, 2009 (the effective date of this AD), whichever occurs first. (ii) Repair before further flight after the inspection specified in paragraph (f)(2) of this AD where any incorrectly installed compression fittings are found. | Follow Cirrus SR22 Service Bulletin SB 2X-30-08, dated November 9, 2009. |
