In certain configurations, landing gear retraction can cause the brake hose to be compressed between the torque link and the emergency flotation gear pipe.  This Directive requires a check for the correct installation of the hoses to prevent failure of the brake hose.

This amendment excludes those helicopters that have incorporated Mod 0745C49.

The original issue of this AD became effective on 23 January 2003.
