Enjoy the added benefits with your
spoiler equipped Cessna 340 airplane!
When it’s time to come down you’ll be glad you have PowerPac Spoilers
installed on your Cessna 340 aircraft.
With PowerPac Spoilers you command descent rates up to 3.5 times faster.
Simply touch a button and PowerPac Spoilers instantly reduce lift and
increase drag.
Deploy your Cessna's PowerPac Spoilers at any speed up to Vne for
rapid descent rates without the need for major power reductions. Avoid
engine shock cooling and maintain cabin pressure.
PowerPac Spoilers are
doubly useful in sudden turbulence by reducing lift-induced loads
carried by the wings. The Jet Type design provides maximum effect, no
drag when retracted and lower installation cost. Plus you can deploy and
retract PowerPac Spoilers in icing conditions.
I used mine on the way home from the convention today. Was
descending into some weather/turbulence and they do a great job at
keeping airspeed under control when coming in through rough air in the
340. Tim Persson, April 2022

flight test data obtained during required FAA certification flight tests

PowerPac
airplane spoilers "Jet Type" design is similar to
those used on commercial jet airliners. The system consists of single
flat plates, 21.00" X 7.750" one on top of each wing that lies flat when not in use.
When deployed, they extend upward into the slipstream at a 60-degree
angle, thereby "spoiling" a portion of the lift being generated by the
wing, while at the same time creating drag. PowerPac
Spoilers are designed to work in conjunction with standard
Cessna 340 aircraft parts.
There is an STC’d PowerPac Spoiler Kit just for your Cessna 340.

certification. Give us a call today: 253-851-1769 or Email Us.
