What the agency says
The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to all restricted category Model CH-47D helicopters. This proposed action would revise the NPRM by expanding the required actions paragraph applicable to all right-hand (RH) forward transmission support beam fittings with any part number, narrowing the area of inspection, and increasing the reporting requirement compliance times. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM and to address some commenters' concerns, the agency is requesting comments on this SNPRM.
