Compliance required as soon as possible but not later than August 15, 1957. Some of the release fittings of the subject belt assemblies are so constructed as to require one particular side of the fitting UP when being inserted in the buckle. It is possible to improperly fasten the belts effected so that the buckle may become unfastened under load. The unsatisfactory release fittings have a tab bent up to an angle of approximately 11 degrees with the plane of the fitting (See Figure 1). To provide for securely assembling the buckle with the release fitting in either position, the tab area indicated in the sketch must be removed or bent flush with the plane of the adjoining metal. This rework applies only to the release fitting shown in the sketch. Other portions of the buckle assembly than that shown should not be modified. This condition has been corrected on all assemblies of current manufacture. FOOTER:
