## The airworthiness directive

47-05-01 CESSNA: (Was Mandatory Note 11 of AD-722-5.) Applies Only to Model T- 50 Airplanes Having a Fuel Shutoff Valve Located in Each Engine Nacelle. These Valves are Controlled by "T" Shaped Handles Located Below the Pilot and Copilot Seats.

Compliance required prior to original certification or, if previously certificated, not later than March 1, 1947.

To prevent the pilot or copilot from inadvertently operating the fuel shutoff valves by striking the "T" shaped fuel shutoff valve handles with their feet, the "T" shaped handles are to be changed to circular shaped handles. To accomplish this a ring having an inside diameter of 3 1/2 inches is to be formed of 1/4 - inch x 0.035 steel tubing and slid over each "T" shaped handle and welded in place. This will result in a handle of this appearance:
