This specification relates to Synchros, 60 and 400 Hz. It is not complete in itself, but shall be used in conjunction with MIL DTL-81963, in which the latter shall be recognized as forming an inherent part of this specification. This standard requires a Qualified Products List (see 6.4).
Rationale: In view of the discontinued use by manufacturers of “GO-NO GO” gages for inspections of splines, the requirement for inspection is revised (see 3.4.4). This revision also provides deletion and addition of applicable documents, clarification of qualification and first article test information, replacements for an obsolete MS17182 (see Note 4 for Figures 5 through 9), and updates to Index.
