This file is an engineering drawing showing technical specifications for a sheave assembly, labeled as drawing number 52-W-1832. The drawing includes both a side sectional view (Section A-A) and a top view of the sheave assembly, which appears to be part of a fairlead beam assembly for an Aircraft Arresting System. The drawing contains detailed specifications including bearing information (MS 32731-118 and MS 32738-23), measurement details for pin placement, and notes regarding sharp edges and manufacturing allowances. The drawing contains a distribution statement restricting its use to U.S. Government agencies and their contractors, with an export control warning. The contract number referenced is F416J8-EC-C-Q027-0029 with FSC M21435.

The drawing is one component of a larger solicitation (FA481925Q0006) for 40 Heavy Weight Fairlead Beam Assemblies, which are used to direct purchase tape paths in Aircraft Arresting Systems. This particular drawing represents the rear sheave assembly portion of the overall fairlead beam system. The technical specifications shown in this drawing would need to be adhered to by any manufacturer awarded the contract.
