STC SA04-71, STC SA2100NY

Our original flight-testing showed us a number of things:

  1. The time from throttle application to the aircraft on the step appeared to be cut in half
  2. The aircraft climbed faster
  3. An increase in cruise airspeed was apparent
  4. There was no need for "cruise flaps"

And from the maintenance perspective, anyone who has tried to change a mag or starter, or adjust points or find an oil leak will love this modification.

The Holmes Extended Engine Mount is a perfect addition to any DHC-2 equipped with the Sealand Aviation Ltd Cabin Extension Kit and the Sealand Aviation Cabin Kit with the Alaska Door.
