## Summary

This document announces a reopening of the comment period for the above-referenced NPRM. The NPRM proposed the adoption of a new airworthiness directive for all ATR Model ATR42 and ATR72 airplanes. That NPRM invites comments concerning the proposed requirements for revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.
