Summary
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A319-100 and A320- 200 series airplanes. The original NPRM would have required repetitive inspections of the wing-tank fuel pumps, canisters, and wing fuel tanks for detached identification labels, and corrective action if necessary. The original NPRM resulted from several incidents of detached plastic identification labels found floating in the wing fuel tanks. This action revises the original NPRM by expanding the applicability and mandating modification of the fuel strainers at the fuel pump and suction bypass intakes. We are proposing this supplemental NPRM to prevent plastic identification labels being ingested into the fuel pumps and consequently entering the engine fuel feed system, which could result in an engine shutdown.
