Correction: This is an amendment to a previous synopsis dated 8 Jan 2001. This synopsis was inadvertently labeled a repair requirement. It should have been for a spares buy of 5 each Electric Control Units which is needed for the NVG on the MH53J aircraft. P/N: 2230-0206-03-1, NSN 6220-01-455-9720BZ, this is a Special Operations Forces requirement. Numbered Note 26 does apply. All other information publicized in the original synopsis is correct.
