## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This proposed AD was prompted by reports of arcing and smoke emanating from the windshields. This proposed AD would require a revision to the maintenance or inspection program, as applicable, to include an inspection of the windshield moisture seal for signs of cracks, erosion, wear, and other deterioration; doing that inspection and repair if necessary; and re-torqueing the windshield heater terminal lugs and applying sealant to the windshield heater screw heads. We are proposing this AD to address the unsafe condition on these products.
