The airworthiness directive
47-43-01 CESSNA: (Was Mandatory Note 12 of AD-768-5.) Applies to 120 and 140 Aircraft Serial Numbers Up to and Including 11842.
Compliance required prior to January 1, 1948.
Reroute the lower end of the primer line located on the left side of the firewall and rotate the strainer fitting so that it points downward and to the left at an angle of 60 degrees to the horizontal. Slip approximately 6 inches of vinylite tubing over the upper and lower ends of this primer line and install a shield around this line between the two pieces of vinylite tubing. This will preclude the possibility of fuel coming in contact with the left exhaust manifold in the event of a failure in this primer line.
(Cessna Service Letter No. 34, dated March 24, 1947, covers this same subject.)
