## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by reports from the manufacturer that center overhead stowage (COS) boxes could fall from their supports under forward load levels less than the 9G forward load requirements as defined by Federal Aviation Regulations. This proposed AD would require modifying COS boxes by installing new brackets, stiffeners, and hardware as needed. We are proposing this AD to prevent detachment of COS boxes at forward load levels less than 9G during an emergency landing, which would cause injury to passengers and/or crew and could impede subsequent rapid evacuation.
