Tamarack Aerospace's Active Winglets Nearing Approval
Company expects European approval soon, FAA STC by Q2 next year.

Without Atlas, it would be necessary to beef up wing structure before adding aftermarket winglets - a much more costly solution. Photo: Rob Finfrock

First announced in 2013, Tamarack Aerospace Group's active winglet system is nearing European approval for use on straight-wing Cessna CJs, with FAA certification expected to follow. "We are currently on track to certify our active winglets on all CJ 525 models by the end of the year," Tamarack COO Brian Cox told AIN. "Sometime in October, the EASA will submit the official validation package to the FAA, and we believe this process will culminate in STC issuance from the FAA early in the second quarter of 2016."
