FAA Grounds Tamarack Atlas-equipped CJs
Tamarack maintains that two previously issued service bulletins remedy control issues in Citations equipped with active load-alleviating winglets.

The FAA has grounded all Cessna Citation Model 525, 525A, and 525B (CJ1, CJ2, and CJ3) light jets equipped with Tamarack Aerospace active load alleviation (Atlas) winglets. The action follows last month’s issuance of an emergency airworthiness directive (AD) by the European Union Aviation Safety Agency (EASA), and while a reciprocal directive from U.S. regulators was expected, a Tamarack representative expressed “disappointment” to AIN at the timing and wording of the FAA action.
