## The airworthiness directive

47-07-01 BELLANCA: (Was Mandatory Note 4 of AD-773-5.) Applies to Models 14-13, 14-13-2 All Serial Numbers Up to and Including 1200.

To be accomplished not later than next periodic inspection.

Check fuel selector valve handle for proper indexing on valve by setting handle in L-ON and in R-ON position, by disconnecting the fuel line, and by blowing through line when there should be free passage of air. After tank positions have been set, the valve handle and shank should be permanently marked to identify the index position. Attach handle positively to shank by drilling through one side of the handle and halfway through the shank with a drill of number 53 size and inserting a pin of 1/16-inch diameter drill rod.

(Bellanca Service Bulletin No. 4 covers inspection of the valve handle installation.)
