Airworthiness Directive · Amendment 39-16923 · Engine air intake
Cirrus Design Corporation Airplanes
This AD applies to the following model and serial number airplanes, certificated in any category:
(1) Group 1 Airplanes: Cirrus Design Corporation Model SR22T airplanes, serial numbers 0001 through 0169, except 0004, 0019, 0027, 0047, 0097, 0126, 0127, 0135, 0138, 0139, 0144, 0154, 0155, 0157, 0158, 0159, 0160, 0161, and 0163.
(2) Group 2 Airplanes: Cirrus Design Corporation Model SR22T airplanes, serial numbers 0004, 0019, 0027, 0047, 0097, 0126, 0127, 0135, 0138, 0139, 0144, 0155, 0157, 0158, 0160, and 0161. These airplanes had the reinforced silicone fiberglass seals installed at the factory but the box flange welds and slots may be incorrectly modified. Therefore, this AD still applies to these airplanes.
We are adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SR22T airplanes. This AD was prompted by reports of partial loss of engine power due to a dislodged rubber gasket/seal being ingested into the turbocharger. This AD requires inspection and modification of the air box flange welds and slots and installation of induction system air box seals as applicable. We are issuing this AD to correct the unsafe condition on these products.
Comply with this AD following Cirrus Design Corporation SR22T Service Bulletin SB 2X-71-17 R1, dated September 30, 2011, within the compliance times specified, unless already done.
(1) Group 1 Airplanes: Within the next 10 hours time-in-service (TIS) after February 29, 2012 (the effective date of this AD), inspect the air box flange welds and slots, make modifications as necessary, and replace the induction air box seals with reinforced silicone fiberglass seals part number 29486-001.
(2) Group 2 Airplanes: Within the next 10 hours TIS after February 29, 2012 (the effective date of this AD), inspect the air box flange welds and slots and, as necessary, make modifications.
Credit will be given for actions required in paragraphs (g)(1) and (g)(2) of this AD if already done before February 29, 2012 (the effective date of this AD) following Cirrus Design Corporation SR22T Service Bulletin SB 2X-71-17, dated July 21, 2011.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
