PARTS UPDATES
LANDING GEAR SELECTOR SWITCHES COMING SOON
Thanks to efforts with a supplier, new landing gear selector switches (P/N 8906K3639) are now available from Twin Commander Aircraft.
The new selector switch is applicable to all aircraft with electro-hydraulic landing gear systems. The list price is $151.11. Please contact an Authorized Twin Commander Service Center if your switch is in need of replacement.
IMPROVED FUEL TANK VENT HEATER AVAILABLE AT REDUCED PRICE
Twin Commander Aircraft has improved the design of the Fuel Tank Vent Heater.
The new design improves reliability by minimizing exposure of the heater element to the environment, thereby reducing corrosion and cracking. The new vent heater, P/N 630432-1, replaces P/N 100201-1 and is applicable to all aircraft prior to the 690C series with flight-into-known-icing capability.
The price of the newly designed unit is $1,085—a savings of 33 percent compared to the previous version. Twin Commander Aircraft has several of the new vent heaters in stock. Contact an Authorized Twin Commander Service Center for more information.
NEW ENGINE CONTROL NUT CORRECTS LEAK ISSUE
Twin Commander Aircraft is testing a new, improved part used to secure engine control cables to the power levers in turboprop Twin Commanders.
The part, a nut, is on the threaded end of each of the push-pull cables that are actuated by the engine power and condition levers. The nut also forms a seal on the outer casings of the cables to maintain pressurization, but existing nuts have a tendency to leak past the seal. Warm, moist air from inside the cockpit that leaks past the seal can freeze when it hits cold ambient air, making it difficult to manipulate the power levers.
The newly designed replacement nut has an improved seal that will do a better job of preventing leaks and holding pressurization. It currently is undergoing cycle testing. A vendor is prepared to begin producing the nuts when testing is completed.
For more information on when the nut may be available for installation, contact Twin Commander Aircraft or a factory authorized Service Center.
