## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Dornier Model 328-300 series airplanes. This proposed AD would require installing an additional mounting angle for the respective de-icing pipes at rib 9 in the leading edge area of the left- and right- hand wings. This proposed AD is prompted by chafed de-icing lines in the wing leading edge area. We are proposing this AD to prevent chafing of the de-icing lines, which could result in a reduction in functionality of the anti-ice system, and possibly reduced controllability and performance of the airplane in icing conditions.
