Action
Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period.
Summary
We are revising an earlier proposal for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding airplanes to the applicability and adding a measurement of the distance between the hooks of the torsion spring of the lanyard assembly. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes.
