GUT Works received Aviat Husky N53HY for export to England, and coincidentally the owner desired an avionics upgrade and autopilot installed to assist with IFR operations in European airspace. Before dismantling the aircraft for crating, we installed, calibrated and tested the following equipment (presented in the photos below):

  • KN62A DME
  • KI525A HSI (slaved)
  • KX165A NAV COM
  • S-TEC System 30 Autopilot with GPSS interface and altitude hold
  • #2 Altimeter
  • Heated Pitot/Static probe
  • Emergency Hand-held Radio Interface

Had it not been for a structural airframe member in the way of the new HSI indicator, we could have made minor panel changes and fit in the new instrumentation with some compromises. That was not to be, however, so a new, uncompromising CAD-designed panel was designed, resulting in a height increase of less than 1". The engine cowl is still visible from the pilot's viewpoint, so visibility is not sacrificed. It was important to us to maintain the proper orientation of panel instruments during this upgrade, and making a new panel allowed us to do that while also making for an attractive installation.
