Action
Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period.
Summary
We are revising an earlier proposal for certain The Boeing Company Model 767-300 and -300F series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding new high frequency eddy current (HFEC) inspections for cracking of an expanded area of the lower outboard wing skin for certain airplanes. 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.
