Action
Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.
Summary
We are revising an earlier proposed airworthiness directive (AD) for certain B/E Aerospace protective breathing equipment (PBE) that is installed on airplanes. The NPRM proposed inspecting the PBE to determine if the pouch has the proper vacuum seal and replacing if necessary. The NPRM was prompted by reports of a compromise in the vacuum seal of the pouch that contains the PBE. This action revises the NPRM by requiring replacement of the PBE following newly issued service information regardless of inspection results. We are proposing this supplemental NPRM (SNPRM) to correct the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
