## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This proposed AD was prompted by a report of cracking on the radius of the rib 0 forward longeron at frame 26. This proposed AD would require a one-time inspection for defects of the radius, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
