Summary
We are revising an earlier proposal for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes; Model 757 airplanes; and Model 767 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding Model 737-8 airplanes and future Model 737 airplanes to the applicability. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes.
