This examination shall be conducted on the MB-U and MB-6 harness loops only, subsequent to the proof load test after
21、a waiting period of not less than 24 hours. Loop acceptability shall be determined by use of an inspection tool conforming to figure 1. The inspection tool shall be held in one hand and the harness loop pushed over the small end of the tool with the sewn end of the loop against the chamfered side of
