Summary
We are revising an earlier proposal for certain Gulfstream Aerospace Corporation (Gulfstream) Model G-IV and Model GIV-X airplanes. This action revises the notice of proposed rulemaking (NPRM) by proposing to require a later revision of the service information to update the life limits and inspection requirements in the airworthiness limitations section (ALS) of the aircraft maintenance manual (AMM). 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.
