The airworthiness directive
55-14-01 BELL: Applies to Model 47G Helicopters Below Serial Number 1317.
Compliance required as soon as possible, but no later than September 15, 1955.
In order to provide additional support for the No. 1 bearing hangar, P/N 47-664-148-15, and the forward cross tube of the tail boom, P/N 47-267-088-1, it is mandatory that the support bracket installation be completed in accordance with Bell Drawing 47-267-402-1.
(Bell's Mandatory Service Bulletin No. 99, dated April 29, 1955, covers this same subject and outlines the details for the installation.)
NOTE: This does not eliminate the need for the mandatory daily preflight inspection for cracks in the No. 1 bearing hangar area called for in Bell's Maintenance and Overhaul Manual.
