## Summary

We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2014-12-13, which applies to all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The first SNPRM proposed to revise the proposal by expanding the inspection area, and terminating, rather than superseding, the requirements of AD 2014-12-13, after accomplishment of the initial inspections. This action proposes to again revise the proposal by requiring the installation of standard-size fasteners for a certain configuration. We are proposing this AD to address the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the first SNPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
