REGULATORY TEXT:  
85-23-06 CESSNA: Amendment 39-5225. Applies to Model T303 (Serial Numbers T30300001 thru T30300315) airplanes certificated in any category.

Compliance: Required within the next 10 hours time-in-service from the effective date of this AD, unless already accomplished.

To preclude the possibility of the fuel metering unit tee fittings from leaking and causing a fire, accomplish the following:

(a) Remove both engine cowlings to the extent required to adequately examine the turbocharger inlet area and fuel metering units. Visually inspect the turbocharger inlet and surrounding area for evidence of significant damage caused by exhaust gas leakage. If noted, prior to further flight, repair the damage and eliminate the cause of the leak.

(b) With the aircraft auxiliary fuel pumps on and the mixture control in the idle cutoff position, visually inspect the fuel metering unit tee fitting for cracking and leakage in the threaded area that goes into the fuel metering unit. If a crack and resultant leak is detected, prior to further flight replace the fitting, using a wrench on the fitting, to isolate the effects of attaching and tightening the fuel lines. Do not over torque the fitting when installing it on the metering unit.

(c) The aircraft may be flown in accordance with FAR 21.197 to a location where this AD can be accomplished.

(d) Within five (5) days of accomplishing this AD, report, in writing, all defects found during accomplishment of this AD to the Manager, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. (Reporting approved by the Offices of Management and Budget under OMB No. 2120-0056.)

(e) An equivalent method of compliance may be used when approved by the Manager, Wichita Aircraft Certification Office, Federal Aviation Administration, Central Region, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209.

This amendment becomes effective on February 5, 1986, to all persons except those persons to whom it has already been made effective by priority letter from the FAA dated November 14, 1985, and is identified as AD 85-23-06.
