G1000-Twin-CommanderAll pilots are schooled in the importance of continuously and skillfully practicing see-and-avoid to ensure that your day doesn’t end badly due to a collision with another aircraft, especially in the terminal area. One way to help other pilots be successful at seeing you is to retrofit your Twin Commander with a new High Intensity Discharge Light kit with pulsing technology. And, Twin Commander is running a special limited-time offer of a $600 discount on the price of the kit.

The kit (Custom Kit 182) contains hardware to install the HID pulse light on the nose gear on a variety of Twin Commander models. It can be installed as a retrofit to an existing non-pulsing incandescent light, a factory installation, or as a first-time nose-gear light. The impossible-to-miss high-intensity pulsing light provides excellent conspicuity for your aircraft.

CK182-1 is for 500S, 680W, 681, 685, and 690A/B Twin Commanders without a nose recognition light. CK182-2 is for a 500S, 680W, 681, 685, and 690A/B with CK151 (incandescent light kit) installed. CK182-3 is for the 690C/D and 695/A/B with factory-installed nose landing lights.

The $600 discount goes away May 1, so order yours today. Contact a factory-authorized Twin Commander Service center for more information.


With the next Twin Commander University a year away, it’s time to start thinking about where it should be held. As was the case for the very successful 2015 university in Savannah, Georgia, Twin Commander Aircraft is asking you to help out in the selection process.

The first step is identifying a region in the United States where you would like to see the University “campus” established. Then we’ll propose various venues in the region from which to select. Eventually we’ll narrow the choice to two or three locations from which a final selection will be made.

So let’s get started. From the following list of regions, please select your first and second choice. We’ll report the results in the next newsletter, and ask you for your favorite destinations within that region.

Thanks for participating.


Twin Commander Aircraft has issued a Maintenance Alert calling for inspection and, if necessary, replacement of the elevator bobweight support arms on 690D (Model 900) and 695A and B (Model 1000) Twin Commanders.

The bobweight inspection is to occur at the next 150-hour aircraft inspection and every 150 hours thereafter. The inspection focuses on the area where the bobweight is attached to the support arm. Cracks have been found in that area on an affected aircraft.

The bobweight assembly is located beneath the baggage compartment floor. Its function is to provide consistent elevator control force at all airspeeds.

The procedure detailed in the Maintenance Alert calls for inspection of the support arms at the weight attachment point as well as the hardware associated with the attachment (the 530534-501 arm and the 530546-501 channel attachment to the 530535-1 collars and 530542-1 shaft), for cracks and/or loose fasteners or other damage. If cracks are found, the 530534-501 arm and the 530546-501 channel must be replaced with a new 530534-501 arm and 530546-503 channel. The 530546-503 channel has been lengthened to nest with the 530534-501 arm for the full length, providing better structural arrangement at the weight attachment point.

If loose fasteners or any other damage are found at the collars and shaft attach points, contact Twin Commander Aircraft.

The inspection must be performed even if the arms have been previously replaced, and results of the inspection should be reported to Twin Commander Aircraft.

Twin Commander Aircraft has released two more Custom Kits designed to prevent moisture-related corrosion beneath the dorsal fin on various model Twin Commanders.

Earlier we reported on Custom Kit (CK) 193 for Twin Commander models 690A/B, which is comprised of a weep-hole system of parts, including shims, to be installed under the existing dorsal to provide channels for moisture to drain out of the cavity. Or, better yet, opt for CK 196, which replaces the original plastic dorsal fin with one constructed from stronger, more durable composite laminate material. The new dorsal fin also incorporates channels to disperse moisture. CK 195 is the new replacement dorsal fin for Twin Commander models 500S, 681, 685 and 690.

The latest Custom Kit for the Dorsal Water Evac System is CK 198 for late-model Twin Commander Jetprops (690C/D, 695, and 695A). The kit includes shims that are placed under the existing dorsal to allow moisture underneath the dorsal to drain and evaporate. CK 200 is a complete replacement composite laminate dorsal shell for Jetprops that incorporates channels to disperse moisture underneath the dorsal.

Contact your Twin Commander-authorized Service Center for more details.


One of the important benefits of doing business with a factory-authorized Twin Commander Service Center is the corps of highly experienced technicians who will attend to your aircraft. One of the requirements for achieving and maintaining authorized service center status is that technicians who work on Twin Commanders receive initial and periodic factory training. That training, combined with the years of experience many technicians have with Twin Commanders, means you’ll get the best from the best.

Two seven-day Twin Commander Maintenance Initial training classes have been scheduled for 2016, one for May 9-17, and another September 12-20. The class takes technicians through the various systems on the aircraft, using training aids for visual and tactile reference. Participants also will have access to live aircraft for reference.

Participating technicians are issued a training binder with a printed copy of the presentation and various handouts.

The class culminates with a graded exam. Upon successful completion of the class, technicians receive an official certificate and record of the training.

The two maintenance training classes will be held at Eagle Creek Aviation Services in Indianapolis. For more information, contact Mike Grabbe at [email protected]; telephone 317-293-6935 or cell 317-752-3708.

Special Discount on Enviro Air Cycle mod

Get some climate change going in your Twin Commander. Twin Commander Aircraft is offering a special discount off the list price for Custom Kit (CK) 183 to convert a Sundstrand bleed-air environmental system to an Enviro system. CK 183 is applicable to all serial-number 690Cs, and Ds, and all 695s, 695As, and 695Bs. If you fly a 690C or 695 that has had CK 141 installed, you can upgrade to CK 183 for even better airflow at a fraction of the cost of the complete CK 183 install. The special discount applies to CK 183 kits ordered before the end of the year. Plus, take an additional 10 percent off all parts required to complete the installation of an Enviro air cycle machine that isn’t already included in the CK183 kit. Kits are in stock and available for immediate shipment.

Custom Kits Offer Choice of Improved Dorsal Fin

A recent Maintenance Alert issued by Twin Commander Aircraft addresses the potential for corrosion to develop as a result of moisture that becomes trapped under the dorsal fin on Model 690A and B Twin Commanders. The original dorsal fin design for the 690A/B does not allow for dispersion of moisture that builds up on the fuselage beneath the dorsal, and this can lead to corrosion on the fuselage skin.

The trapped moisture problem can be eliminated by installing Custom Kit (CK) 193, which is comprised of a weep-hole system of parts, including shims, to be installed under the existing dorsal to provide channels for moisture to drain out of the cavity. Or, better yet, replace the original plastic dorsal fin with one constructed from stronger, more durable composite laminate material. The new dorsal fin also incorporates channels to disperse moisture. CK 195 is the new dorsal fin for Twin Commander models 500S, 681, 685 and 690; CK 196 is for the 690A/B.

Legacy Acquires Parts Overhaul and Repair Business

Legacy Aviation, an authorized Twin Commander Service Center, has acquired the landing gear and component repair and overhaul business from Higher Planes, a long-time provider of parts for Twin Commanders and several other airframes.

Legacy has moved tooling, equipment, inventory, and FAA-approved data from the Higher Planes facility in Conroe, Texas, to Legacy’s base at Clarence E. Page Field in Yukon, Oklahoma, west of Oklahoma City. The business will be renamed Legacy Aviation Components. Higher Planes founder Barry Cain is serving as a consultant to Legacy during the transition. Trey Wallace will make the move from Higher Planes to become shop supervisor at Legacy Aviation Components.

“Higher Planes has been in business for 23 years,” noted Legacy President and CEO RJ Gomez. “Every Twin Commander Service Center uses Higher Planes for landing gear, hydraulic, and component overhaul and repair.”

The Legacy Aviation Components shop should be fully operational by the end of 2015, Gomez said. There should be no interruption in providing parts, nor any decrease in the quality of repairs and overhauls as a result of the transition, he added.

For more information, contact RJ Gomez at Legacy Aviation Services at 405-350-2100.
