Summary
We are revising an earlier proposal for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding a requirement to replace the lower lock link of the nose landing gear (NLG), which would terminate the repetitive inspections proposed in the NPRM. This action also reduces the applicability in the NPRM. 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.
