Airworthiness Directives; Airbus SAS Airplanes

The FAA is revising a notice of proposed rulemaking (NPRM) that applied to certain Airbus SAS Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4- 605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This action revises the NPRM by adding airplanes to the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since this action would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
