ACTION: Final rule; request for comments. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This AD was prompted by the loss of a windshield in flight, and the consequent rapid depressurization of the flight deck, which caused damage to flight deck items and systems and subsequent thermal shock and overheat, damage to windshield structural plies, and impaired structural integrity of the windshield.
