## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by significant changes made to the airworthiness limitations (AWLs) related to fuel tank ignition prevention and the nitrogen generation system. This AD would require revising the existing maintenance or inspection program, as applicable, to include new or revised AWLs. We are proposing this AD to address the unsafe condition on these products.
