2012-24393 Airworthiness Directives; Airbus Airplanes Proposed Rule We are revising an earlier proposed airworthiness directive (AD) that would supersede an existing AD for certain Airbus Model A318, A319, A320, and A321 series airplanes. For certain airplanes, that NPRM proposed repetitive inspections for cracks of the forward lug of each main landing gear (MLG) support rib 5 fitting and repair if necessary; and removing Model 318 airplanes from the applicability. That NPRM was prompted by reports of cracks found in the forward lug of the MLG support rib 5 fitting. This action revises that NPRM by adding Model A318 airplanes and others to the applicability; and requiring repetitive detailed inspections for cracks of the MLG support 5 fitting, and repair of any cracks. We are proposing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. 2012-10-03 2012 10 https://www.federalregister.gov/documents/2012/10/03/2012-24393/airworthiness-directives-airbus-airplanes https://www.govinfo.gov/content/pkg/FR-2012-10-03/pdf/2012-24393.pdf Transportation Department; Federal Aviation Administration 492,159 We are revising an earlier proposed airworthiness directive (AD) that would supersede an existing AD for certain Airbus Model A318, A319, A320, and A321 series airplanes.
