April-May 2017



Twin Commander Aircraft LLC has engineered a solution to replacing certain wear items in Sundstrand Environmental Control Units used on various Twin Commander model aircraft.

The problem has been unavailability of replacement flexible hose couplings used in Sundstrand ECUs on the 690C, 690D, 695, 695A, and certain serial-number 695B Twin Commanders. The couplings connect metal piping in the ECU, and protect the piping from vibration and thermal expansion. The couplings are made from special materials to withstand the high temperatures and pressures. The largest of the couplings is about six inches long and four inches in diameter.

Twin Commander Aircraft recently designed, developed, and certified replacements for the couplings, and parts are available. The replacement parts do not come in a kit, and can be ordered individually. However, it is recommended that if one coupling needs replacing, a full replacement set should be installed. Some units require five flexible hoses, some seven, depending on aircraft model and serial number.

For more information about the replacement Sundstrand couplings, contact your authorized
Twin Commander Service Center.


Eagle Creek Aviation Services and its family of companies have received the AMT Diamond Award of Excellence from the FAA for participating in the 2016 Aviation Maintenance Technician Awards Program. This is the sixth consecutive year that Eagle Creek Aviation and Naples Jet Center—both authorized Twin Commander Service Centers—have received the award, and the first year for Montgomery Aviation under new ownership by Eagle Creek.

AMTs at Naples Jet Center hold Diamond Awards from the FAA

The FAA AMT Awards program encourages individual AMTs and their employers to invest in continuing education. The Diamond award is reserved for companies that achieve 100 percent participation from eligible employees. In 2016, 35 AMTs at Eagle Creek Aviation and its family of companies spent more than 1,500 hours in training—online, in the classroom, and on the job.

“As a company, we are committed to excellence in everything we do, including ensuring that we continue to invest in our technicians through training and education,” said Eagle Creek Aviation CEO Matt Hagans. “We believe our customers are best served by professionals who are continually learning and utilizing industry best practice.

In the last Twin Commander eLetter we told you how Jean-Luc Pous went from a 10-year-old refugee from French-occupied Algeria to a top-level engineer and manager at Schlumberger to a professional pilot and, now, the owner of a 690B Twin Commander. The new issue of Twin Commander’s Flight Levels magazine, available at http://www.flightlevelsonline.com/, has the full story of his remarkable life and dual careers. The new issue also takes a look at the three most important considerations when transitioning to a Twin Commander, written by J.R. Bob Husky, an experienced Commander instructor and mentor pilot. Jim Worrell assesses the market from the buyer’s and seller’s perspectives, and Air Journey founder Thierry Pouille reports on flying your airplane to Cuba. You can read the entire issue at http://www.flightlevelsonline.com/.



With few details about the Trump Administration’s proposed tax reform package available, it’s too early to scrutinize the full extent of its potential effect on aircraft owners. However, some observations can be made. Following is a portion of the “Business Flying and Taxes” column in the current issue of Twin Commander’s Flight Levels, now available for reading at www.flightlevelsonline.com. The column was written by Suzanne Meiners-Levy, Esq., Legal Advisor for Advocate Consulting Legal Group, PLLC.

One cornerstone of the Trump tax plan is a significant decrease in corporate tax rates, as well as taxes paid by owners of flow-through businesses, including S corporations, partnerships, and Schedule C businesses that flow through to 1040 returns. Current corporate rates at 35% are proposed to be cut to 15% in the Trump plan, and although that may be not be politically feasible, the Kiplinger Tax Letter believes that a top rate of 25% is politically likely. Perhaps even more significantly, flow-through profits from S corporations, partnerships, and Schedule C businesses that currently are taxed at the owners’ 1040 rates are also subject to significant cuts, with a proposed rate of 15%. (The House GOP Blueprint calls for 20% corporate rates and 25% flow through rates. The Trump plan calls for both rates to cap at 15%.)

Why does this rate shift make purchases of new equipment installed on aircraft in 2016, and likely 2017 (contingent upon the date of reform), a unique opportunity? Deductions taken for expensing property or depreciation are commonly referred to as “timing differences,” given that any deduction taken, to the extent that it exceeds the actual loss in value in the property, is subject to recapture at the time the property is sold or no longer used for business. While there is no reason to believe at this time that recapture would not occur in future tax years, that recapture would be treated as ordinary business income in the year the property is taken out of service. Assuming a significant and potentially lasting change in business tax rates, the deductions taken for the property in years before rate cuts are likely to save significantly more tax dollars than those due at the time the property is sold, given the potentially large reduction in rates. For example, if corporate taxes decrease by 50% as proposed, the tax savings at purchase will double that owed upon disposition. This, combined with 50% bonus depreciation in 2017 and the $500,000 expensing election, may make this the ideal time to upgrade equipment on your aircraft.

Jean Luc Pous

Jean-Luc Pous has an interesting, and impressive, resume:
Born in French-occupied Algeria just before the start of an eight-year war, at age 10 and under fire he fled the country. He later earned a mechanical engineering degree in France, but wanted to become a military pilot—a childhood visit to a military base with his father had ignited a passion to fly. However, lacking the required eyesight, he used the expertise he had gained as a parachute instructor in college to join the French military as a paratrooper. It was the proper thing to do “to repay them (French paratroopers) for their support in the war,” Pous says. “They were the only ones who protected us.”

After completing his military service in 1979 he went to work for Schlumberger, then the largest oil services company in the world, and spent the next 10 years as a logging engineer and manager throughout the Middle East. At the end of his Middle Eastern stint Pous took flying lessons in France. His next Schlumberger assignment was in the U.S., where his responsibilities grew to eventually manage much of the company’s manufacturing operations—16 centers with 2,500 employees.

Pous left Schlumberger after 29 years to follow his childhood dream of flying. He earned all the necessary certificates and ratings to fly professionally, and within a year of retiring from Schlumberger he bought the airplane he had been renting—a Shrike Commander. Three years later he and a partner upgraded to a 690B Turbo Commander that he used for charter. The partner eventually left, but Pous kept the airplane, which he now uses exclusively for his own use.

“I enjoy executive flying with my wife and two cats,” Pous says. “Typically, I go to the Bahamas, Santa Fe, Colorado—anywhere in USA I desire to visit.”

Pous has earned four type ratings, three of which are for warbirds. He flies a variety of aircraft professionally, instructs in Commanders, and owns a Jet Provost with partners. He will admit he is living the dream. “You don’t realize how much America has to offer unless you come from someplace else,” he says.

For the rest of Jean-Luc Pous’s story, be sure to read the next issue of Twin Commander’s Flight Levels magazine.



Twin Commander Aircraft has developed a solution to the problem of damage to Commander fuselage belly skins caused by debris thrown up by the spinning nose wheel. The solution comes in the form of the new Custom Kit (CK) 199 Belly Skin Protection System. The heart of the system is a small fender positioned immediately aft of the nose wheel that deflects debris picked up on the takeoff and/or landing roll, preventing it from striking and possibly damaging the fuselage belly skin.

CK199, which also includes mounting braces and installation instructions, is expected to be available in late April at factory authorized Twin Commander Service Centers.

The low-slung Commander profile puts the extended nose wheel in close proximity to the belly of the airplane, making it vulnerable to damage from nose wheel FOD, especially when operating from grass, gravel, or deteriorating paved runways. The predecessor company to Twin Commander Aircraft had developed a nose wheel fairing intended to deflect debris, but the design caused significant drag, which forced the pilot to use lower airspeeds and angles of attack when the nose wheel was extended.

Twin Commander Aircraft used a supercomputer to apply computational fluid dynamics to identify sources of the drag, and to test more advanced, lower-drag solutions. The result is the fender in CK199, which has less than half the drag of the previous design while significantly reducing the potential for FOD.

The new design was tested on a Commander in September 2016. Ground taxi and flight tests were performed to confirm its effectiveness while ensuring the kit does not contribute to nose wheel shimmy or nose wheel extension or retraction problems.

The installed kit does not interfere with the use of a tow bar or most powered tugs.

For more information about CK199, contact your authorized Twin Commander Service Center.


SIMCOM Aviation Training has begun training Commander pilots at its Orlando headquarters facility.

SIMCOM is moving the Commander program from its Dallas-Ft. Worth, Texas, training center to its Lee Vista center north of Orlando International Airport. The 690B simulator is now operational at Lee Vista. SIMCOM can conduct initial and recurrent training on the simulator and the first customer training class was held in their Level B 690B simulator in late February. FAA requalification of the 690B is expected within the next 60 days, at which time customers will be able to count instrument approaches conducted in the simulator toward instrument currency. In the meantime, customers receive course completion certificates but no instrument credit.

The 1000 simulator is scheduled to be operational at Lee Vista in mid-April. It will be inspected by the FAA for requalification at some point after it is operational. SIMCOM will be able to conduct 1000 training on the 690B through differences training until the 1000 sim is operational.

For more information please contact the SIMCOM Sales Department at 866-238-4468.



One very important reason to use an authorized Twin Commander Service Center is the factory’s requirement that technicians receive formal, Commander-specific training. That ensures your airplane will receive the best, most informed care.

Two such Twin Commander Maintenance Initial training classes have been scheduled for 2017: May 8-16, and September 18-26.

The seven-day course takes the A&P mechanic (or equivalent) thru the various systems in a classroom environment using AMM and AIPC documents along with associated publications and physical training aids. The technicians also have access to live aircraft. Each student is issued a training binder with a printed copy of the presentation and various handouts. The course concludes with a graded exam. Upon successful completion, clients receive an official certificate of training and a record of training.

The classes are held at Eagle Creek Aviation (KEYE) in Indianapolis. For more information about Twin Commander Maintenance Initial training classes contact Mike Grabbe at Eagle Creek at 317-293-6935, cell 317-752-3708, or email [email protected]

Global TC

Global Aviation Services has moved! The factory-authorized Twin Commander Service Center relocated in January to David Wayne Hooks Memorial Airport (KDWH) from George Bush Intercontinental Airport (KIAH), where it had been based since its founding in 1987.

The new location at David Wayne Hooks, a privately-owned public-use general aviation airport in Tomball north of downtown Houston, is far more accessible to customers, especially those flying in, than was Houston’s huge airline airport, explained Doug Ray, president of the company. Global is operating out of Tomball Jet Center on the west side of KDWH.


Global is an FAA-approved repair station authorized by Twin Commander Aircraft to provide the full range of inspection, repair, modification, and upgrade services and parts sales. Global also services avionics with an emphasis on Garmin equipment.

Global was founded by Jim Ray to provide brokered maintenance services, primarily to AiResearch (now Standard Aero) located across the runway. When Jim’s son Doug and his wife Sherrie took over the business in 2001, they brought maintenance in-house. Since then the Rays’ strategy has been a steady, deliberate growth with an emphasis on customer relationships and preserving aircraft.

The company specializes in turboprop and jet services, but Commander work has been its “bread and butter,” Doug said, especially during the sluggish economy of the past several years.

Two things customers appreciate about Global are its small size and stable workforce, Doug said. “We are a smaller shop, and customers are happy to see the same crew servicing their aircraft. We have a loyal work force that is very knowledgeable. One example is our landing gear overhauls—we have no repeat or warranty claims on the work we do.”

Think you’ve paid excessive fees at some FBOs in the past? AOPA would like to hear from you. AOPA says its review “has found indications that some fixed-base operators may be charging excessive fees for fuel and other services. According to federal law, prices and services at airports that receive funds under the Airport Improvement Program must be ‘fair, reasonable and non-discriminatory,’ but AOPA members have reported experiencing issues with things like landing fees, ramp fees, and fuel pricing,” mostly at larger airports where FBO consolidation has occurred. AOPA would like to hear from Twin Commander owners and pilots who believe they have been subject to excessive FBO charges.

SimCom Aviation Training is closing its Dallas Training Center just north of DFW airport and moving Twin Commander simulators and training programs to its Lee Vista Orlando Training Center north of Orlando International Airport.

SimCom acquired the Twin Commander pilot training program from FlightSafety International in 2011, and moved it from FSI’s Houston center to SimCom’s newly acquired Dallas facility, which also supports other manufacturer make and model training programs. The decision to now close the Dallas center is the result of several factors, including lack of space to handle the larger full-flight simulators that SimCom plans for its future growth in other training programs, SimCom President Eric Hinson explained. Also, some of the Dallas center’s busier training programs are replicated at SimCom’s Lee Vista and Scottsdale, Arizona, facilities. “We’ll be able to adequately serve the market with two locations instead of three,” Hinson noted.

SimCom will operate two full-motion Commander simulators at its Lee Vista Orlando center including one configured as a JetProp 1000 with TPE331-10 engines, Garmin 530, and visual display with day and night depiction. The second is configured as a 690B with Garrett TPE331-5 engines, a Garmin 530 and 430 in the panel, and a visual display that duplicates both day and night conditions. The company will no longer use a fixed-base visual-motion device configured as a 690A. “It has limited capability, and we’ll have more than enough capacity using the two motion sims,” Hinson said.

The move to the Lee Vista Orlando Center should prove beneficial to the Twin Commander program because of better technical support—24 simulator technicians on site at Lee Vista compared to four at the Dallas Center—and dedicated software engineers on site, Hinson added. That support should improve the reliability of the two Twin Commander sims, an issue that Hinson acknowledged is a concern for customers. Improving reliability is one of the prime reasons for moving the program to the Orlando facility, Hinson said. “It will allow us to deliver a better product.”

SimCom is exploring options for upgrading the avionics in the two Twin Commander sims with newer-generation Garmin products including a G600, GTN750/650, or some combination, Hinson said. He asked Commander customers to weigh in on the decision. “I encourage the market to give us feedback,” he said. “We’d like to hear from customers.”

One factor that SimCom must consider when upgrading the avionics is that it serves more international than domestic Twin Commander customers, and many operate older models with analog cockpits.

SimCom’s Twin Commander pilot training options include a five-day initial, three-day recurrent, three-day second-in-command recurrent and a two-day express recurrent.

SimCom also offers several specialty courses including:

  • Crew resource management
  • High-altitude endorsement
  • Multi-engine instrument refresher
  • Pinch-hitter
  • Turbine transition for piston pilots

We’ve been asking you in a series of polls where the next Twin Commander University should be held. The results pointed to one of several Texas cities as the favored venue.

For a variety of reasons, we’ve had to make the decision to postpone the University, to spring 2018. A rebounding economy means that more companies, associations, and groups are having conferences. That has made it difficult to find an appropriate venue that can accommodate the University in our preferred time frame.

Also, we’ve been very busy at Twin Commander Aircraft with various projects, and we want to make sure we can devote the time needed to plan and stage the kind of University experience you’ve come to expect.

So, please adjust your calendar for a spring 2018 University. We’ll be talking more about it in future issues of Flight Levels.


Twin Commander Aircraft has released Custom Kit (CK) 203 pertaining to the elevator and rudder trim potentiometer. The kit applies to all JetProp models (690C, 690D, 695, 695A and 695B). The elevator and rudder trim potentiometer detects position and movement of pitch and yaw trim control surfaces, and sends a signal to the cockpit trim indicators.

CK203 provides approval, instructions and piece parts for the elevator and rudder trim potentiometer replacement (part numbers 85026-503 and 850633-503). Those parts no longer were available, and service centers repairing potentiometers were having to buy alternative parts that required trimming and FAA 337 field approval. No trimming or field approval is required when installing CK203.

Estimated time to remove old parts and replace them with CK203 is 1 hour for the rudder and 1.5 hours for the elevator.

For more information, contact an authorized Twin Commander service center.


Dr. Paul Buza’s Southern AeroMedical Institute—SAMI—is offering to conduct its DeSat slow-onset hypoxia training course exclusively for Twin Commander pilots.

SAMI’s DeSat program teaches the importance of recognizing the dangers of slow-onset hypoxia. The SAMI program was developed as an evolution of the standard FAA model, which focuses on rapid/explosive decompression.

The training is conducted in SAMI’s high-altitude chamber while flying a Garmin G1000 and utilizing a Zodiac Aerospace Mask System. Each pilot is provided a video recording of the chamber experience, which begins at 10,000 feet and climbs up to 22,000 feet. The pilot is in communication with ATC while flying the Garmin G1000 simulator panel. In addition to ATC communication, Dr. Buza supervises the pilot’s oxygen saturation levels and pulse to help them safely recognize a minimum of three lifesaving sensations.

The FAA and international high-altitude training standards involve large groups in altitude chambers where the time of useful consciousness is three minutes or less. In SAMI’s program, pilots are able to feel the effects of slow-onset hypoxia over significantly longer periods of time in a safe training environment. The video provided to the pilots is an excellent tool to use through the years as recurrent training.

The DeSat course, conducted at SAMI’s facility in Melbourne, Florida, includes four hours of ground school (three hours on hypoxia, and one hour on fatigue), a chamber training flight, catered lunch, a hypoxia training video, a hypoxia fingerprint card, a review with Dr. Buza of a video of your chamber session, and an altitude chamber certificate.

The special Twin Commander course would begin at 1:00 p.m. on a Friday and conclude the next afternoon. The price will be deeply discounted for the group.

The course is limited to 12 people. For more information about SAMI’s slow-onset hypoxia training, visit http://sami-aeromedical.com/hypoxia-training-programs/advanced-chamber-program/ or contact Jenelle Buza, SAMI’s Project Director, at [email protected], telephone 321-676-3200.
