to identify and replace all windshields that had been produced
using the PR1829 polysulfide sealant within the electrical
connector terminal block assembly. That program was initiated in
early 2010 and extended to the replacement of approximately 1,500
units within the world-wide Airbus fleet. The ATSB have been
advised that due to limited fleet-wide completion of the windshield
replacement program, the European Aviation Safety Authority (EASA)
is considering the implementation of an Airworthiness Directive
(AD) that will require all European operators of applicable Airbus
aircraft to comply with the Airbus windshield replacement program.
