Summary
This document withdraws a notice of proposed rulemaking (NPRM) that would have revised AD 93-19-06, which requires repetitively inspecting acrylic cabin and cockpit windows for cracks on Fairchild Aircraft SA26, SA226, and SA227 series airplanes, and, if cracks are found that exceed certain limits, replacing that window. The revision document was proposed to more fully define the crack limits and establish clearer repetitive inspection intervals under those crack limits for the affected airplanes. Several incident reports of cockpit side window failures on the affected airplanes that were in compliance with AD 93-19-06 has prompted the FAA to propose a modification to these windows in another AD action, which would supersede the current AD. The FAA is withdrawing the current NPRM and issuing another NPRM to propose this modification.
