REGULATORY TEXT:  
77-16-05 CESSNA: Amendment 39-2998. Applies to Models 210-5(205), 206, P206/TP206, U206/TU206, 207/T207, and 210/T210 series airplanes of the serial numbers specified below.

Compliance: Required within the next 25 hours time-in-service after the effective date of this AD, unless already accomplished.

To prevent malfunction of the P/N C291503-0101 or P/N 1216100-1 fuel selector valve, accomplish the following:

A. On Model 210-5(205) series (serial numbers 205-0481 thru 205-0577), Model 206 series (serial numbers 206-0001 thru 206-0275), Model P206/TP206 series (serial numbers P206-0001 thru P20600647), Model U206/TU206 series (serial numbers U206-0276 thru U20603123), Model 207/T207 series (serial numbers 20700001 thru 20700322), Model 210/T210 series (serial numbers 21058221 thru 21061154, and T210-0001 thru T210-0454) airplanes, examine the aircraft maintenance records to determine whether the fuel selector valve has been changed subsequent to December 19, 1975. If the valve has not been changed, make an entry in the maintenance record indicating this AD is not applicable to the airplane and no further action is necessary. Examination of the records and the record entry may be accomplished by the owner/operator.

If the valve has been changed subsequent to December 19, 1975, accomplish a fuel valve inspection and, if indicated, replacement in accordance with paragraph C. below.

B. On Model U206/TU206 series (serial numbers U20603124 thru U20603712, U20603714 thru U20603791, U20603793 thru U20603797, U20603799 thru U20603803, U20603805, U20603808 thru U20603812, U20603814 thru U20603846, U20603848, U20603850, U20603851, U20603853 thru U20603857, U20603861, U20603862, U20603867 thru U20603871, U20603875, U20603876, U20603882 and U20603886), Model 207/T207 series (serial numbers 20700323 thru 20700373, 20700375 thru 20700394), and Model 210/T210 series (serial numbers 21061155 thru 21061731, 21061733 thru 21061766, 21061768 thru 21061860, 21061862 thru 21061881, 21061883 thru 21061987, 21061990 thru 21061993, 21061995 thru 21062005, 21062007 thru 21062009, 21062012 thru 21062017, 21062020 thru 21062022, 21062024 thru 21062027, 21062029, 21062033 thru 21062037, 21062043) airplanes, accomplish a fuel selector valve inspection and, if indicated, replacement in accordance with paragraph C. below.

C. 1. Place fuel selector valve in OFF position.

2. Remove selector valve handle and associated parts. Obtain access to the valve by removal of the control valve pedestal and selector valve access plate from the floor.

3. Check the selector valve serial number. If the serial number is 1421 thru 3269 inclusive, accomplish the pull test inspection described in paragraph C.4. below. If the serial number is not within this block, the valve is not affected, and the aircraft may be returned to service after reassembly.

4. Using tools fabricated in accordance with Figure 1, or an equivalent test arrangement, accomplish a pull test on the selector valve in accordance with the following procedures:

a. Remove safety wire, roll pin, and valve handle shaft from valve control yoke.

b. Feed cable through hole in yoke and crimp cable securely. Place bar in loop in other end of cable.

c. Remove four screws securing selector valve cover. Break the seal between the cover and body and rotate the cover to positively assure it is free.

d. Attach a tensiometer to the cable in the section between loops and from a seated or squatting position, with one foot on each side of the valve, using the legs and arms to lift, apply an upward force of 130 pounds minimum to 150 pounds maximum directly in line with the shaft while observing the shaft for movement. Exert upward force gradually. If any upward movement of valve shaft is noted, release force immediately. Drain fuel from airplane and install a new valve in accordance with the aircraft's Service Manual Instructions.

CAUTION

If the shaft pulls out of the valve body, fuel spillage may result. Therefore, all precautions applicable to working with or around open fuel should be observed.

e. If no upward movement of the valve shaft is noted or evident, reassemble the valve and aircraft and return to service.

AD 77-16-05

D. Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

Cessna Service Letter SE77-22, dated June 27, 1977, or later approved revisions pertain to the subject matter of this AD.

This amendment becomes effective August 11, 1977.
