Summary
This document proposes to revise an earlier proposed airworthiness directive (AD), which would have superseded AD 93-19-06. That AD currently requires repetitively inspecting acrylic cabin and cockpit side windows for cracks on certain Fairchild Aircraft SA26, SA226, and SA227 series airplanes, and, if cracks are found that exceed certain limitations, replacing that window. The previous document included the following: the proposed requirement of modifying certain cockpit side windows; more fully-defined crack limitations; and more clear repetitive inspection intervals for the affected airplanes over those included in AD 93-19-06. Comments received regarding the NPRM have prompted the Federal Aviation Administration to change the proposal and allow the public a further opportunity to participate in the rulemaking process. The actions specified by the proposed AD are intended to prevent acrylic cabin or cockpit side window failures, which, if not detected and corrected, could result in airframe damage and decompression injuries.
