## Summary

We propose to adopt a new airworthiness directive (AD) for all 328 Support Services GmbH Model 328-100 and -300 airplanes. This proposed AD was prompted by reports indicating corrosion on the horizontal stabilizer bearing supports at the contact surface to the horizontal stabilizer rear spar. This proposed AD would require inspections for corrosion and any other damage (i.e., cracking and chafing) of the horizontal stabilizer rear bearing supports, replacement of the affected horizontal stabilizer rear bearing supports if necessary, and modification of the horizontal stabilizer rear spar. We are proposing this AD to address the unsafe condition on these products.
