## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This proposed AD would require repetitive inspections of the wing top skin under the rib 0 joint strap, and related investigative and corrective actions if necessary. This proposed AD results from a report of a significant crack in the wing top skin under the rib 0 joint strap. We are proposing this AD to detect and correct corrosion and cracking in that area, which could result in reduced structural integrity of the wing.
