Tamarack Asks NTSB To Reconsider Probable Cause
Tamarack Aerospace is disputing many points in the NTSB's final report on the 2018 crash of a CitationJet equipped with Tamarack winglets.

Tamarack Aerospace has submitted a petition for reconsideration to the NTSB, asking it to reconsider the probable cause conclusion in the crash of a Cessna CitationJet on Nov. 30, 2018. The jet was equipped with Tamarack winglets and the Active Technology Load Alleviation System, which uses Tamarack Active Camber Surfaces to alleviate structural loads.
