EASA AD US-2018-09-04
[Correction] Landing Gear - Main Landing Gear Actuator Attachment Fitting - Inspection / Maintenance Program Revision
Summary
Correction to Airworthiness Directive 2018-09-04 issued by the Federal Aviation Administration (FAA) affecting Gulfstream Aerospace Corporation Model G-IV and GIV-X airplanes. The correction addresses a typographical error in the referenced Customer Bulletin number related to the inspection and maintenance program for the main landing gear actuator attachment fitting. The directive mandates inspection cycles and maintenance program revisions to prevent fatigue cracks in the main landing gear actuator attachment fitting.
What Changed
The correction changes the incorrect reference from Customer Bulletin No. 283A to the correct Customer Bulletin No. 238A dated June 15, 2017, in paragraphs (h)(3) through (5) of the original AD. The rest of the original airworthiness directive remains unchanged, but the entire rule is republished for clarity.
Why It Matters
This correction ensures that maintenance and inspection procedures reference the correct service documents, which is critical for proper compliance and safety. Accurate references help operators and maintenance personnel perform the required inspections to detect potential fatigue cracks in the main landing gear actuator attachment fittings, thereby preventing landing gear failure and associated safety risks.
What To Do
Operators of affected Gulfstream Model G-IV and GIV-X airplanes must inspect maintenance records to determine if the specified repair has been incorporated and then follow the inspection and maintenance instructions in the corrected Customer Bulletin No. 238A. Compliance with the AD is required within 100 flight hours or 3 months after June 11, 2018, whichever occurs later. The maintenance program must be revised to include the updated inspection cycles.
