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 measures, including an Alternative Method of Compliance (AMOC), allowing Tamarack Active Winglet-equipped Citation jets to return to flying status after prior emergency airworthiness directives.
- Aircraft must comply with Service Bulletin 1480 (a free actuator replacement/upgrade) for the return to service, and Tamarack is extending product warranties by 24 months for affected customers.
- The scrutiny on Tamarack's winglets stemmed from 2019 upset incidents, not a recent NTSB investigation, and this resolution follows the company's bankruptcy filing in early June.
