The FAA has signed off on an alternative method of compliance (AMOC) for a controversial airworthiness directive that could have grounded several hundred airplanes with Superior Air Parts aftermarket cylinders.
FAA Eases Impact of Superior Cylinder AD
Key Takeaways:
- The FAA has approved an Alternative Method of Compliance (AMOC) for an airworthiness directive (AD) affecting aircraft with Superior Air Parts aftermarket cylinders.
- The original AD would have required replacement of these cylinders after 12 years, potentially grounding over 1,000 airplanes.
- Under the new AMOC, owners can now comply through ongoing inspections (visual, compression, leak, and borescope) every 50 flight hours or annually, allowing cylinders to continue service until TBO or a new 17-year time-in-service limit.
