ACTION: Supplemental notice of proposed rulemaking (SNPRM). SUMMARY: The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to all restricted category Model CH-47D helicopters.

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.
