Action
Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period.
Summary
We are revising an earlier proposal for Zodiac Aero Evacuation Systems (formerly known as Air Cruisers) fusible plugs installed on emergency evacuation equipment for various transport category airplanes. This action revises the notice of proposed rulemaking (NPRM) by extending the proposed compliance time, clarifying the applicability, and clarifying certain proposed requirements. We are 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, we are reopening the comment period to allow the public the chance to comment on these changes.
