Paragraph (g)(1)(ii)(B) of Docket No. FAA-2008-0415; Directorate Identifier 2007- NM-256-AD calls out for “initial repair/overhaul” where Boeing MPD item 27-108-00 calls out for a “Restore”. SCA believes that operators may need clarification on whether or not a “Restore” meets the intent of the NPRM. Additionally, the repetitive items listed within SB 737-27A1277 are closely related to Boeing 737NG MPD items 27-102-00, 27-108-00, and 27-110-00 in procedure as well as interval. If operators are following these MPD items, can they take credit for those already established maintenance requirements in lieu of the SB action? SCA believes that because these particular MPD items already exist it would be advisable to change these to CMR requirements instead of mandating AD action.
