## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, -500 series airplanes. This proposed AD was prompted by the results of a fleet survey that revealed cracking in the bulkhead frame web at a certain body station. This proposed AD would require repetitive inspections of the bulkhead frame web at a certain station, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.
