## 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 certain Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes. That NPRM invited comments concerning the proposed requirements for doing repetitive ultrasonic inspections to detect cracking in the axle adaptor, replacing the axle adaptor if necessary, and ultimately doing the terminating action of inspecting and modifying the main landing gear shock strut and axle adaptors. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.
