What to do
Operators of affected Gulfstream Model G-IV and GIV-X airplanes must revise their maintenance or inspection programs to incorporate the updated airworthiness limitations within 12 months of the effective date, December 13, 2019. No alternative inspections or intervals may be used unless approved as an alternative method of compliance by the FAA. Stakeholders should obtain and apply Gulfstream Document No. GIV-GER-0008, Revision D, to ensure compliance.
Summary
The document titled "Time Limits / Maintenance Checks - Airworthiness Limitations Section - Amendment" is a final rule airworthiness directive issued by the FAA for Gulfstream Aerospace Corporation Model G-IV and Model GIV-X airplanes. It mandates revisions to the airworthiness limitations section of the aircraft maintenance manual to incorporate updated inspections and life limits addressing fatigue cracking of principal structural elements. This directive affects specific serial numbers of the G-IV and GIV-X series airplanes.
What changed
This new airworthiness directive requires operators to revise their maintenance or inspection programs to include the updated airworthiness limitations specified in Gulfstream Document No. GIV-GER-0008, Revision D, dated August 20, 2018. The revision introduces new and revised inspections and life limits based on fatigue and damage tolerance testing and updated analysis. It also corrects part numbers for certain components and adds new life limits for specific fuselage cockpit side posts.
Why it matters
This directive is critical for aviation professionals because it addresses an unsafe condition related to fatigue cracking in principal structural elements, which could compromise the structural integrity and safety of the affected aircraft. Compliance ensures continued airworthiness and helps prevent potential loss of control due to structural failure. Maintenance, repair, and operations teams must update their programs to align with the latest safety standards and regulatory requirements.
