2012-27125 Airworthiness Directives; Airbus Airplanes Proposed Rule We propose to adopt a new airworthiness directive (AD) for certain Model A330-200, -300 and -200 Freighter series airplanes; and all Model A340-200 and -300 series airplanes. This proposed AD was prompted by a determination that the bonding lead from a certain isolation valve to a frame was too close to an electrical harness, which might cause chafing between the electrical harness and the associated bonding lead. This chafing could lead to a short circuit of the isolation valve and consequent non-closure of the isolation valve, which would prevent the air-flow to be shut-off in case of fire. This proposed AD would require modifying the bonding lead installation of the isolation valve. We are proposing this AD to prevent such chafing, which could result in non-closure of the isolation valve in the event of a fire and consequent damage to the airplane and injury to its occupants. 2012-11-07 2012 11 https://www.federalregister.gov/documents/2012/11/07/2012-27125/airworthiness-directives-airbus-airplanes https://www.govinfo.gov/content/pkg/FR-2012-11-07/pdf/2012-27125.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to adopt a new airworthiness directive (AD) for certain Model A330-200, -300 and -200 Freighter series airplanes; and all Model A340-200 and -300 series airplanes.
