This document announces a reopening of the comment period for the above-referenced NPRM. The NPRM proposed the adoption of a new airworthiness directive (AD) for certain Boeing transport category airplanes. That NPRM invites comments concerning the proposed requirements for replacing any insulation blanket constructed of polyethyleneteraphthalate (PET) film, ORCON Orcofilm[reg] AN-26 (hereafter "AN-26"), with a new insulation blanket. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.
