Micro regenerates Piper Aztec

ANACORTES, WASHINGTON-BASED MICRO Aero-dynamics has certificated vortex generators for the Piper Aztec, which reduce take-off and landing speeds by delaying stall onset and improving aileron and rudder control at low speed. The vortex generators, 33 of which are placed on each side of the wing leading edge, and 12 each side of the fin, are available for all Aztecs except for the F model.
