	After doing the inspection, remove the placards installed in accordance with Requirement 2b of this AD before further flight.4. For all affected aeroplanes - If the alternate static air source selector valve port is found obstructed by the part number identification placard during the inspection detailed in Requirements 1, 2a, and 3 of this AD, remove the placard from the valve body, discard the placard, and assure that the port is open and unobstructed.5. For all affected aeroplanes - When a replacement valve is needed, only install a P/N 2013142-18 alternate static air source selector valve that has been inspected and the port is found free from obstruction.The procedures required to accomplish this AD are detailed in Cessna Single Engine Service Bulletin SB08-34-02, Revision 1, dated 6 October 2008; Cessna Caravan Service Bulletin CAB08-04, Revision 1, dated 6 October 2008; Cessna Single Engine Service Bulletin SEB08-5, dated 13 October 2008; or Cessna Multi-engine Service Bulletin MEB08-6, dated 13 October 2008, as applicable.Note 3: FAA AD 2008-26-10 Amdt 39-15776 dated 15 December 2008 refers.
Compliance:	For Requirement 1 - Within the next 100 hours time-in-service (TIS) after the effective date of this AD or within the next 4 months after the effective date of this AD, whichever occurs first.For Requirement 2a - Within the next 10 days after the effective date of this AD.For Requirement 2b - Before further flight after the effective date of this AD.For Requirement 3 - Within the next 100 hours TIS after the effective date of this AD or within the next 4 months after the effective date of this AD whichever occurs first.For Requirement 4 - Before further flight after the inspection required in Requirements 1, 2a, and 3 of this AD.For Requirement 5 - As of 10 days after the effective date of this AD.
	This Airworthiness Directive becomes effective on 16 January 2009.
Background:	Reports of improper installation of the part number (P/N) identification placard on P/N 2013142-18 alternate static air source selector valves prompted the issue of several ADs against various models of Cessna aircraft in response to the United States Federal Aviation Administration (FAA) issuing AD 2008-10-02.Since then the FAA has received reports of 15 aeroplanes not previously affected by AD 2008-10-02 with a P/N 2013142-18 installed and the alternate static air source selector valve port was found obstructed by the P/N identification placard.
