## The airworthiness directive

48-13-06 BELLANCA: Applies to Models 14-13, 14-13-2 Serial Numbers 1060 Through 1310.

Compliance required after each 25 hours of operation.

To prevent failure of the four engine-cowl-support brackets, Bellanca P/N 9892-13, mounted on the firewall and possible cowl loss in flight, the brackets should be closely examined for cracks. If cracks are noted, heavier brackets available from the factory should be installed, in which case inspection is no longer required.

(Bellanca Service Bulletin No. 16 dated December 8, 1947, covers this same subject.)
