Twin Commander Aircraft has developed a kit that ensures good results in an area that can be difficult to protect from pressurization leaks — the rudder-pedal horns.
Leaks in the boots that enclose the rudder-pedal horns can result in noticeable loss of pressure differential, which means a higher cabin altitude at cruise, company officials explain. Twin Commander’s new rudder-pedal seal kit includes a plug for the rudder-pedal horns/brake valve arms and improved boots that help preserve cockpit and cabin pressurization.
The new kit replaces original factory-installed plugs on the rudder-pedal horns and brake links with an enhanced-material design. The rudder pedal boots are secured to the new-design plugs for a tight seal to prevent pressurized air in the cabin from leaking out, company officials add.
The new rudder-pedal seal kit is in stock at authorized Twin Commander Service Centers as CK-184 for Twin Commander models 680, 685, 690, and 690A/B/C; and CK-185 for the 690D and 695A.
