Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319-100, A320-200, A321-100, and A321-200 series airplanes. This proposed AD would require repetitive inspections for corrosion in the inside and outside lower walls of each type A, D, E, and F lavatory wall that has at least one wall-mounted cabin attendant seat, and related investigative and corrective actions if necessary. The repetitive inspections may be terminated by repairing the wall with composite material, or replacing the entire wall with a new wall made of composite material. This proposed AD results from reports of corrosion in the lower part of the lavatory walls due to water ingress. We are proposing this AD to detect and correct corrosion and damage on the lower part of the lavatory walls, which could compromise the structural integrity of the cabin attendant seat attachments, and cause injury to the cabin attendants during a crash landing.
