On July 10, the FAA approved an alternative method of compliance (AMOC) for all Active Winglet equipped Citation jets, which returned CJ1, CJ2, CJ3 and M2 aircraft to flying status. EASA regulators also recently resolved flight restriction issues in Europe created around the recent Emergency Airworthiness Directive (EAD) against Tamarack active winglet installations awaiting a final resolution to the EAD. The AMOC requires aircraft operators to comply with Service Bulletin 1480 prior to flight that calls for replacing or upgrading a small actuator on the trailing edge of the camber surface. Tamarack is providing the product improvements from SB 1480 free of charge to all customers.
Tamarack Aerospace Restarts the Clock on Warranties
Key Takeaways:
- The FAA and EASA have approved an Alternative Method of Compliance (AMOC), lifting flight restrictions on active winglet-equipped Citation jets after previous upset incidents, requiring a free actuator replacement/upgrade.
- The flight restrictions were initially imposed due to reports of Tamarack's Atlas active winglets malfunctioning and causing pilots difficulty in maintaining aircraft control.
- Tamarack Aerospace, despite filing for bankruptcy in early June, is extending customer warranties by an additional 24 months as a gesture of gratitude for those affected by the grounding.
