Twin Commander Has Two Free SB241 Kits to Give Away

Could You Be One of the Recipients?

 Twin Commander owners who have not yet complied with Service Bulletin 241 affecting certain models can now receive a free service bulletin compliance kit from Twin Commander Aircraft. The kit has a value of $16,325 and includes the major components necessary to complete SB241, which is a compliance method for FAA Airworthiness Directive 2013-09-05 addressing potential cracking in the aft pressure bulkhead. SB241 and the AD apply to 690/A/B model Twin Commanders. Later-model Twin Commanders –– 690C/Ds and 695/A/Bs –– have a different wing-to-fuselage design and are not affected by the service bulletin or AD.

To be eligible for a donated kit an owner must acquire the kit and have it installed at one of 13 Factory Authorized Twin Commander Service Center facilities, a worldwide network dedicated to Twin Commander service, sales, and support. Only two kits are available, so hurry to get yours and upgrade your Twin Commander.

Maintenance Training Session a Success

One of the great benefits of owning and operating a Twin Commander is a robust network of Factory Authorized Service Centers. Service center maintenance is of a high standard in part because maintenance technicians attend type-specific training. The training, offered twice a year through Eagle Creek Aviation Services, is an eight-day course specific to the various models of Twin Commanders. The spring session was a big success, with two mechanics taking part in an on-site class at Eagle Creek, and nine attending at an operator’s facility in Canada. Mike Grabbe, a Twin Commander expert, wrote the course and teaches it through a series of classroom and hands-on aids. “Most mechanics are tactile learners,” he said. The sessions held at Eagle Creek in Indianapolis have the advantage of accessing aircraft in all states of repair or refurbishment. While the class is geared toward maintainers, Grabbe has had pilots attend in the past. He said most attendees have been techs for at least two years.

The next class is scheduled for November 4 through 13. Contact Mike Grabbe at [email protected] for more information.

A Twin Commander in the Texas Hills

The Flying L Ranch was once a thriving fly-in community in the Texas Hills north of San Antonio. Unfortunately for pilots, the Flying L is now a resort and dude ranch sans landing strip, although the original clubhouse in the photo still stands. Do you know more about this airplane, or what brought the airplane to the Ranch?

Sultans of Service

With a legacy airframe, maintenance and support are the keys to retaining utility and value. As a Twin Commander owner the most comprehensive, informed, and experienced service you can get is at a factory authorized service center. The Twin Commander service center network is unmatched in supporting all Twin Commander model airframes, and it’s why the airplane has continued to thrive for decades. Read the latest issue of Flight Levels Online to find out more about what makes service centers special, where you can find them, and why it’s a great idea to take your airplane to an authorized service center.

The Thin Red Line

With so many different operating parameters, keeping tabs on what a turbine engine is doing can be quite difficult. That’s why Honeywell developed the SRL, or single red line computer. Turbine inlet temperature is the primary limiting factor in a turbine engine, but a standard temperature probe can’t survive in that environment. Like many turbines the TPE331 uses exhaust gas temperature as the major performance parameter. The relationship between TIT and EGT is calculated in the background using the single red line computer, and then displayed to the pilot. Want to know more? Check out Honeywell Engines Program Pilot Advisor Robert Erlick’s story in the latest issue of Flight Levels Online. 

Training the Techs

Twin Commander technician training is coming up. The next session will be held March 11 to 20 at Eagle Creek Aviation Services in Indianapolis. The course is taught by Eagle Creek’s Mike Grabbe, who has decades of experience both working on and teaching others how to maintain Twin Commanders. Although the course is open to all maintenance technicians, and even owners, it’s imperative for factory authorized service center technicians to attend. That’s because part of the commitment of being a factory authorized service center includes sending technicians to formal Twin Commander maintenance training. And it’s why owners have the assurance they are receiving excellent support when using an authorized service center. The eight-day course covers everything a technician needs to know to begin working on the Twin Commander, including documentation, systems overview, and more.

Fun Fact

From reader John Wood: “Some pilots may think of the propeller as a fan, producing thrust and pushing the plane through the air. The British have the right idea in calling the propeller an ‘airscrew.’ At cruise your Twin Commander propellers turn one revolution for every 20 feet traveled through the air. They are truly acting as airscrews.
“You can see this when conditions are just right. Sometimes on a dark night flying through moisture there will be a trailing white cloud attached to each propeller tip. From the back seats especially, every time the strobe flashes you will see these spirals trailing along each side of the aircraft.”

Readers Are Equipping with ADS-B early

The FAA currently estimates that around 69,000 aircraft have equipped with ADS-B. That’s seemingly a large number, but it’s far below the estimated 180,000 aircraft that will eventually need to equip to continue to fly where a transponder is required today.

Twin Commander owners and Flight Levels eNews readers are ahead of the game. In the last issue we asked how many had equipped with ADS-B and the results were encouraging. Of those who responded, 73 percent had already equipped.

A Twin Commander Fun Fact

The propeller rotation speed on the Dash 10 version of the Honeywell TPE-331 engine is about 1,700 rpm. At this power setting the engine’s hot section turns at an incredible 40,000 rpm or more. The engine’s reduction gearbox ratio is 26:1 in order to get reasonable propeller rpms.
