REGULATORY TEXT:  
71-09-07 R1 CESSNA: Amendment 39-1202 as amended by Amendment 39-5445. Applies to turbocharged Models TU206 Series, TP206 Series, T207 Series (all serial numbers), and Models T210 thru T210N (Serial Numbers T210-0001 through T210-0454 and 21059200 through 21064897) airplanes certificated in any category.

Compliance: Required as indicated in the body of the AD.

To prevent exhaust gases from entering the cabin, accomplish the following:

(a) Within the next 25 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished within the last 25 hours TIS, and thereafter at intervals not to exceed 50 hours TIS since the last inspection per this AD prior to its revision, inspect the exhaust manifold heat exchanger in accordance with the following:

(1) Test the complete exhaust manifold in the cabin heat exchanger area for cracks in accordance with the following procedures, or the more detailed procedures, outlined in the Cessna Service Manuals for the specified airplanes.

(i) Remove the heater shroud so that all surfaces of the exhaust manifold heat exchanger are exposed.

(ii) Attach the pressure side of an industrial vacuum cleaner to the tailpipe opening, using a rubber plug to effect a seal as required.

(iii) With vacuum cleaner operating, check the complete exhaust manifold in the heat exchanger area manually by feel or by using a soap solution and watching for bubbles. The exhaust manifold in the heat exchanger area must be free of air leaks.

(2) If cracks, breaks, or any leakage along the exhaust manifold cabin heat exchanger are found during the pressure test required by paragraph (a)(1) of this AD, prior to further flight replace the defective part with an airworthy part.

NOTE: Cessna Service Letter SE71-11, dated April 16, 1971, covers this same subject.

(b) An equivalent means of compliance with this AD may be used if approved by the Manager, Wichita Aircraft Certification Office, FAA, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209.

All persons affected by this directive may obtain copies of the documents referred to herein upon request to the Cessna Aircraft Company, Piston Aircraft Marketing Division, Post Office Box 1521, Wichita, Kansas 67201; or the FAA, Office of the Regional Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.

Amendment 39-1202 became effective May 4, 1971.

This amendment, 39-5445, becomes effective on November 26, 1986.
