Sandpoint, Idaho-based Tamarack Aerospace announced June 7 that it voluntarily filed for Chapter 11 bankruptcy protection earlier in the month, a decision the company termed "a direct result" of recent Airworthiness Directives from the FAA and European Union Aviation Safety Agency (EASA) that have "effectively grounded" Cessna CitationJets, CJ1s, CJ2s, and CJ3s equipped with its active load-alleviation system (Atlas) winglets.
