Airworthiness Directives; The Boeing Company Airplanes

This document announces an extension of the comment period for the above-referenced NPRM, which proposed the adoption of a new airworthiness directive (AD) for certain The Boeing Company Model 737- 600, -700, -700C, -800, -900, and -900ER series airplanes. That NPRM invited comments concerning the proposed requirement to modify the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This extension of the comment period is necessary to provide all interested persons an opportunity to present their views on the proposed requirements of that NPRM.
