Key Takeaways:

  • Tamarack Aerospace filed for Chapter 11 bankruptcy following FAA and EASA airworthiness directives that effectively grounded Citation jets equipped with its Atlas winglets.
  • The grounding directives were issued due to multiple reported in-flight upset incidents where the Atlas winglets, which use active load-alleviation tabs, were implicated in control difficulties and a fatal accident investigation.
  • Tamarack has issued free upgrades to address potential tab asymmetry, reporting no incidents in upgraded aircraft, and believes these updates will lead to the lifting of the AD restrictions.
