requisitioned as 4" x 4" x 1/2". When the drawing was issued it was drawn as 5" x 5" x 5/8=.

He wondered about material control on taese hanger Will probably, in the fu ture , take a look and see if you have material control problem Mr. Parsons asked Mr. Fuller regarding the 1/16" difference, could tne snubber Q have gone in and Mr. Fuller noted be did not think so. He Tu-ther stated at that poit.t the inspection program did not provide enough informatior that g
