Key claim: The FAA is requiring inspection and corrective action on certain Airbus Canada BD-500 airplanes where titanium fasteners were incorrectly installed instead of nickel alloy fasteners at the outer wing box lower skin to center wing box interface.
Abstract
(Rule · Transportation Department, Federal Aviation Administration) The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by the discovery that titanium fasteners had been incorrectly installed in the butt strap at the outer wing box lower skin to center wing box interface in lieu of the correct nickel alloy fasteners. This AD requires the identification of fasteners installed in the butt strap at the outer wing box lower skin to center wing box interface, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Why this matters
The FAA is requiring inspection and corrective action on certain Airbus Canada BD-500 airplanes where titanium fasteners were incorrectly installed instead of nickel alloy fasteners at the outer wing box lower skin to center wing box interface.
