Airworthiness Directives; Airbus Model A300 and A310 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)

Résumé

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 and A310 airplanes; and Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes). This proposed AD would require replacing the pressure limiter of the parking brake system with a new or modified pressure limiter. This proposed AD results from a report indicating that failure of the parking brake system occurred on a Model A300-600 airplane. We are proposing this AD to prevent failure of the parking braking system and interference with emergency use of the brake pedals, which could lead to airplane collision with surrounding objects or departure from the runway.
