The FAA has issued a new Airworthiness Directive (AD) for Cirrus SR22s equipped with an anti-ice system approved for flight into known icing.
The AD, which requires owners to inspect the compression fittings on the anti-ice fluid distribution lines for proper installation and repair any fittings that were not properly installed, is a result of the manufacturer finding some anti-ice fluid distribution lines where the compression fittings were not properly installed, FAA officials said. Improperly installed compression fittings could result in anti-ice fluid distribution line separation which, in turn, 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, FAA officials warn in the AD, which becomes effective Dec. 21.
Cirrus released a Service Bulletin Nov. 9 (SR22 Service Bulletin SB 2X-30-08) that describes procedures for inspecting the anti-ice fluid distribution line compression fittings for proper installation. The service information also describes procedures for properly installing compression fittings on the anti-ice fluid distribution lines.
