Action
Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period.
Summary
We are revising an earlier notice of proposed rulemaking (NPRM) for all Airbus Model A318-111 and -112 airplanes; Model A319- 111, -112, -113, -114, and -115 airplanes; Model A320-211, -212, and - 214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. This action revises the NPRM by expanding the list of affected engine fan cowl door (FCD) part numbers and adding Airbus Model A320-216 airplanes to the applicability. We are proposing this Airworthiness Directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
