Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a report of an uncommanded nose landing gear (NLG) retraction. This proposed AD would require installing a power interruption protection circuit for the landing gear control interface unit (LGCIU). We are proposing this AD to prevent untimely unlocking and/or retraction of the NLG, which, while on the ground, could result in injury to ground personnel and damage to the airplane.
