## The airworthiness directive

52-17-01 BELLANCA: Applies to All Model 14-13 Series Aircraft.

Compliance required by August 15, 1952, with chain tension inspections to be repeated at intervals not to exceed 100 hours.

In order to prevent landing gear retracting chain malfunctionings, install chain guard, Bellanca P/N SK 491 or equivalent (see Figures 2 and 3), in both wings at the rear spar landing gear chain sprocket. Chains should be inspected and adjusted for proper tension. When correctly adjusted, chains should feel approximately as tight as the aileron cables.
