## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes. This proposed AD was prompted by significant changes made to the airworthiness limitations (AWLs) related to fuel tank ignition prevention. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate the latest revision of the AWLs. We are proposing this AD to address the unsafe condition on these products.
