Naples Jet Center Building New Hangar

Naples Jet Center, a Twin Commander Factory Authorized Service Center, is poised to become the biggest corporate operator on the busy Naples airport in southwest Florida, after the recent approval of its plan to build a hangar and office complex totaling 45,000 square feet. The hangar will be large enough to accommodate up to three Global Express business jets, and there will be offices for visiting pilots and the company’s corporate flight department. When combined with Naples Jet Center’s current 80,000 square feet of space, the expansion will give the busy service center more than 120,000 square feet of total operating footprint. The project received approval in mid-February, and is now in the development and design phase. Owner Bruce Byerly is excited about the expansion, and thinks the Naples area has even more growth potential. “We could use the space yesterday,” he said. You can read more about the Naples Jet Center in the upcoming spring issue of Flight Levels Online.

Spend and Receive on Bungees

From now to the end of March, buy one landing gear bungee and get one free as part of the Twin Commander Spend and Receive Promotion. Every model of Twin Commander uses two bungees on each main landing gear to help gravity, the emergency gear extension system, and the hydraulic system to extend the main landing gears over-center and into the down and locked position. If you can squeeze a bungee with your thumb and forefinger and the two sides touch, it’s time to replace it. Now, Twin Commander is offering owners and operators a free bungee when they purchase and install one at a Factory Authorized Service Center. Ask for part number 9044 and receive a little something when you spend a little something.


Did You Know?

Every airplane has a demonstrated crosswind capability or crosswind limitation, and most light airplanes use one number. But certain models of turbine-powered Twin Commanders have two values—one for takeoff and one for landing. The 840 and 1000 both list the maximum demonstrated crosswind velocity for takeoff at 30 knots and landing at 27 knots. This practice of different values for takeoff and landing is more common in transport category aircraft.

Air Journey Restarts International Trips

The global coronavirus pandemic has put a significant strain on companies that intersect in any way with tourism. Among those impacted, Florida-based Air Journey was forced to stop its guided international owner-flown trips. As detailed in the winter issue of Flight Levels now online, the company said it is restarting operations. Throughout the next few months the company will be flying escorted trips through the Caribbean and Central America, following strict health protocols in an effort to keep everyone safe. These include COVID-19 tests prior to departure, occasional rapid tests during the journey, outdoor dining, and so on. Air Journey owner Thierry Pouille said that the new requirements for a COVID-19 test prior to arrival back to the United States will be handled as part of the journey. And as of this writing, inbound quarantines have been proposed but are not federally required. For dates, locations, and more information, go to

The only thing better looking than a Twin Commander on the ground is a Twin Commander in flight. Now, thanks to professional photographer Jessica Ambats and owner Brad Howard, we can enjoy new photos of Howard’s 690B over Southern California. Ambats met Howard and his son, Scott, in Iceland while the pair were on a flight around the world with Air Journey. A few years later they connected for the air-to-air photo shoot and now Ambats is making the photos available for purchase. On Ambats’ website, search for “Commander” to see the photos. Each can be purchased as a print or put on a mug or other keepsake. If you’re looking for more, Ambats performs custom shoots and can give your airplane the star treatment.

Factory Working on Multiple Upgrades

The COVID pandemic hasn’t slowed down the work at Twin Commander Aircraft. Business Unit Director Brian Harbaugh said the company is busy with multiple projects and upgrades, from stocking new parts to developing new Custom Kits and flight manual upgrades. Engineering is currently working on new nacelle bulkheads that provide a more secure fit. A new cabin altitude indicator has been developed and will soon be available as part of a Custom Kit. The factory is also developing a new rudder gust lock that addresses customer feedback. Finally, a pilot’s operating handbook, POH, rewrite for 695s on long-range fuel was recently released, and owners and technicians will appreciate an impending change to the hydraulic pump overhaul procedure that is currently under review should make the process more efficient and result in better performance. “We are always working hard to support the Twin Commander community,” Harbaugh said. “But I’m particularly proud of the team’s work recently to push forward in the face of significant outside challenges. They are fully committed to providing value to owners and the Factory Authorized Service Centers.”

Whether it’s a busy schedule or travel restrictions, getting away right now can be, in some cases, quite difficult. Eagle Creek Aviation Services is hoping to help ease that burden by coming to you. The company has long had a respected mobile team that is dispatched for AOG situations, and that service is now expanding to include mobile inspections. “Leave your Commander in your hangar, and our AOG and maintenance technicians will come to you,” promised a press release. A company representative said each job is currently being custom quoted, with the additional travel expenses baked into the rate. “We want customers to know we can take care of them regardless of where they are,” he said. By leveraging its more-than $15 million in Twin Commander parts inventory, Eagle Creek is able to further save owners and operators time and money. And now, you can add convenience to that list as well.

Technicians Urged to Follow Maintenance Manual During Inspections

Twin Commander Aircraft is asking technicians to use the factory maintenance manual during annual inspections of all Twin Commander aircraft, in particular the piston-powered models. Many technicians follow an official checklist for the inspection, but the factory is urging them to follow the complete guidance for annual and recurrent inspections in Section II of the maintenance manual. Specifically, all technicians should reference Part IV Special Inspection Requirements of Section II for detailed information on inspection intervals and procedures that supplement the basic inspection requirements. Part IV covers items such as inspections after hard landings, as well as special inspections that don’t precisely follow the annual inspection schedule. The checklist doesn’t include these items, and can result in an incomplete inspection.

Twin Commander Flight Group Hosts Successful In-Person Meeting

In-person events are rare these days, but the Twin Commander Flight Group bucked the trend and held its annual meeting in-person earlier this month in Rock Hill, South Carolina. Aircenter, Inc.’s Gary Gadberry was elected as the group’s new president after longtime head Jim Metzger retired. Gadberry said the event drew three piston Commanders and two 840s. “This has been a goofy year to try to pull something like this off,” he said. “But most everyone was excited about it.” There were social events and presentations on important topics, such as the difficult insurance market. Twin Commander Aircraft’s Pam Brown gave a presentation on factory programs, parts support, and new employees. “The idea of the group is to draw a closer feel to the Twin Commander aircraft,” Gadberry said. “Without the factory there’d be no support for the legacy airplanes. We feel like the timing is good for Twin to participate more in piston-powered airplanes.” Next May the group is planning a Caribbean fly-out that will take them through Florida, Puerto Rico and the U.S. Virgin Islands. “I think everyone’s ready for 2021,” Gadberry said.

Business Is Brisk at Service Centers

The Coronavirus pandemic may bring a multi-year downturn to the world’s airlines, but it is not slowing down general aviation and Twin Commander Factory Authorized Service Centers. Aircraft sales are booming, activity is up over seasonal norms, and aircraft charter is coming back to pre-pandemic levels in certain sectors. A representative from Eagle Creek Aviation Services said their charter business went from 30 hours a month when the pandemic struck in March to more than 130 hours a month through the late summer. On average he said they were picking up five new customers a week who were fed up with the airlines. Eagle Creek also recently refurbished three Twin Commanders for Conair Aerial Firefighting.

Winner Aviation, Aero Air, and Gemini Air Group have all recently expanded technician staff to handle increased demand. “When I look at what’s happening at the Twin Commander Factory Authorized Service Centers, I feel good about the future,” said Business Unit Director Brian Harbaugh. “It’s a good time to be part of the Twin Commander family.”

Peace Pilot Completes Polar Circumnavigation in Twin Commander

Robert DeLaurentis, who dubs himself the Peace Pilot for his ambitious polar circumnavigation, has safely landed back in San Diego after 11 months, 26,000 miles, and 170 hours logged flying his 1983 Twin Commander 900 from pole to pole. DeLaurentis faced numerous avionics challenges near the poles, but otherwise the heavily modified airplane performed almost flawlessly. He credits the power of his Honeywell Dash 10 engines and the reliability of the Twin Commander for flying him safely down through South America, over the South Pole, across the Atlantic Ocean, north through Africa and Europe, and then over the top of the world before coming back down through Alaska to his Southern California base. “I’m happy what the flight has done for Twin Commander,” he said. “I think it’s a prideful moment for the community. Twin Commander has been a great supporter.” You can read more about the DeLaurentis flight in the next issue of Flight Levels Online

Shrike Downed Due to Misfueling

Photo courtesy of AVweb

A Shrike operated by the State of Alaska’s Department of Forestry crashed May 28 after it was apparently filled with jet fuel, according to an NTSB report on the accident. The airplane had just taken off from Aniak, Alaska, when both engines quit. The ATP-rated pilot ditched in the shallow part of a nearby lake. The pilot and three passengers on board were seriously injured. According to the NTSB the pilot wasn’t present for the fueling. A line staffer had asked the pilot if he wanted Prist, to which the pilot said no. The fueler apparently didn’t notice the 100LL placard next to the filler port, and the pilot didn’t notice that the receipt said “no Prist” and “Jet A.”  Although numerous fail-safes such as placards and different fuel-filler nozzles and ports are meant to prevent misfuelling accidents, they are still a regular occurrence. Pilots are encouraged to stay with their airplane and supervise the fueling process, especially at unfamiliar airports. And always double-check receipts, which will detail the type of fuel added.

Tribal Knowledge: Avoiding Hot Starts

As a long-time Twin Commander salesman, service center executive, and pilot who frequently ferries airplanes headed to the shop, Bruce Byerly has encountered the occasional airplane that is not quite up to the high standards demanded by most owners and operators and all factory authorized service centers. Stuff happens, sometimes on engine start, and Byerly has had to call on his tribal knowledge to get and keep things going. That’s where we’ll start this tribal knowledge class—with engine starts.

There are situations that increase the potential for exceeding the maximum allowable temperature on engine start—a hot start—such as high ambient temperatures, high altitude, starting the engines with the airplane facing downwind in a strong wind, and a quick turn when the engine core has not had a chance to cool. Regardless, there is no excuse for suffering a hot start, Byerly says. The pilot should see engines temperature rapidly rising in time to abort the start or reduce the fuel flow to the engine, and thus the temperature, using the Horsepower Limiter or, depending on the Twin Commander model, the Torque Limiter switch on the overhead panel.

We’ll have more on tribal knowledge techniques to avoid a hot start in the upcoming issue of Flight Levels Online.
