An Airbus Industrie A320 overran a runway because sealant missing from a cap over its braking dual distribution valve allowed water ingress and freezing. This disabled the aircraft's standby braking system, according to a US Federal Aviation Administration emergency airworthiness directive, which calls for checks to be carried out within 10 days. The FAA acted on advice from the French civil aviation authority, the DGAC. Airbus says it has advised all operators of recommended checks.
