Hagans Inducted into Indiana Aviation Hall of Fame

Matt Hagans, the longtime owner and CEO of Eagle Creek Aviation, was inducted into the Indiana Aviation Hall of Fame (INAHOF) at a ceremony in Carmel, Indiana on October 7. Hagans began his aviation career at Cessna in the engineering and flight test department, where he played a vital role in bringing the 414A to market, and helping to certify the 340’s known icing capability. In 1984 he purchased Eagle Creek Aviation and grew it into a world-class aircraft services company and one of the most active Twin Commander Factory Authorized Service Centers. Under his leadership Eagle Creek was responsible for developing the STC for the Dash 10 engine upgrade, the Garmin G950 STC, and many other advancements.

In 2021 Hagans merged Eagle Creek with Jet Access to create the tenth-largest Part 135 company in the United States. He currently serves on the company’s board, which has nearly 400 employees, 50 Part 135 and training aircraft, and 75 technicians. The Eagle Creek Aviation brand remains strong and intact as a Jet Access company, and continues to operate at the Eagle Creek Airport near Indianapolis. Hagans has more than 17,000 flight hours in a variety of aircraft, including most of the Twin Commander line.

Pam Moore Promoted to Program Manager

Twin Commander’s Pam Moore has been promoted to Program Manager for the company’s type certificate group. As part of her duties, Moore is responsible for the customer-facing side of the day-to-day operation of the Twin Commander and Metro/Merlin type certificates. This includes managing the strategic growth plans, parts ordering and production, customer service and support, supplier management, and more. “I’m thrilled to continue to serve Twin Commander operators and the service center network in my new capacity,” she said. “My goal is to improve parts turnaround times and get us back to one-day order fulfillment.” Moore previously served as the librarian, handling technical publications and drawings in support of customer service and engineering. She encourages customers to reach out at [email protected] with any issues or questions.

TCA Seeks Input from Fire Operators

The United States Forestry Service has implemented a new rule that requires operators who wish to compete for and operate under USFS contracts to comply with a factory approved enhanced inspection program that is specific to each model of aircraft. Up to this point, Twin Commander Aircraft has developed programs for the 690 and 695 series of aircraft only.

Those operators wishing to work with the USFS in 2024 with a Twin Commander other than a 690 or 695 must contact the factory as soon as possible so engineers can develop a program. Without this enhanced inspection program from Twin Commander, you will not be eligible for a 2024 contact with the Forestry Service.

You must email [email protected] and reference “Forestry Service Contract” and the model of Twin Commander you plan to operate in order to be eligible for the 2024 season. If Twin Commander Aircraft doesn’t hear from you by October 31, they can’t guarantee your eligibility for the 2024 fire season.


Parts Availability Looking Up

Global supply chain constraints and a transition to a new parts vendor have brought big changes and a few challenges to the team at Twin Commander Aircraft recently. But Business Unit Director Bob Wilson said the team is working hard to bring continuous improvements to the situation. “We are meeting with the vendor on a regular basis to ensure they are providing ever-better service to our customers,” he said. In addition to regular in-person meetings with the vendor to ensure better parts distribution, Wilson said the factory is also focused on reducing pricing errors. During the transition a few parts were found to have incorrect pricing, so the staff have been correcting those as they come up. “As consumers, we’re all seeing pricing pressures ease with an increasingly robust supply chain, and I’m confident Twin Commander owners will also continue to see an improvement in the availability of parts and prices, as we work hard to improve the workflow between the factory and the vendor.” Check with your preferred Twin Commander Factory Authorized Service Center for current parts availability and pricing.

FAA Issues AD for All V-Band Clamps

Departing from its historical strategy of issuing airworthiness directives as issues appeared on specific aircraft and engine models, the FAA recently finalized a wide-ranging airworthiness directive that compels all turbocharged aircraft to undergo inspection and replacement of certain v-band clamps. At issue is spot-welded, multi-section clamps that attach the exhaust to the turbocharger housing. The agency noted many failures of the parts over the years, and previously issued ADs that impacted specific aircraft models. With this new AD every turbocharged aircraft is impacted. The AD imposes a 500-hour life limit on the part, or 50 hours if time-in-service is unknown. Anticipating parts availability challenges, the FAA is slightly extending the compliance time with inspections during the first few years after the AD becomes effective.

Considering all of aviation’s advances over the last 50 years, one of the biggest must be the global positioning system. Not only does GPS make navigating from point A to point B easier, it is also central to having instrument approaches at small airports all over the country, it supercharges our in-flight weather capabilities, helps with precise fuel calculations, and a host of other things that we now take for granted. If you’ve ever wondered how GPS came about, or how it works, check out Dr. Keith Thomassen’s story in the latest issue of Flight Levels OnlineDr. Thomassen breaks down the history and capabilities of the system in a fascinating way. And put that GPS to use on the epic trip of your dreams with Air Journey, detailed in the latest iteration of Adventure Flying. Air Journey Founder Thierry Pouille details a trip to “the other” Caribbean, including Roatan and Jamaica.

See Ike’s Commander in Action

“These airplanes are nothing more than metal, rubber, and aluminum. But they represent those people who over a stretch of time in our history made something incredible happen.” This quote from Commemorative Air Force (CAF) volunteer Gerald Oliver, said while sitting in front of President Dwight Eisenhower’s L-26 Aero Commander, is an astute observation to what makes airplanes so special to us. Oliver was interviewed as part of a feature story and video published by AOPA on the famous Commander that served as Air Force One and shuttled Eisenhower between Washington, D.C., and his farm in Gettysburg, PA. The CAF restored the airplane, which Oliver claims to be the only flying L-26, and the organization now offers rides in the airplane as a way to generate support and show off a piece of living history for veterans and others. You can watch the full video on YouTube 52(12.8%), and read the story in an upcoming issue of AOPA PILOT magazine.

Maintenance Alert Issued for Cracks in Lower Wing Skin Cutouts

Twin Commander Aircraft has issued a maintenance alert 66(16.3%) for cracking in the lower wing skin cutouts in the forward portion of the main landing gear truss. A longtime area of focus for owners and technicians, two reports from the field noted small cracks extending forward and aft from the radii of the lower wing skin cutouts. The maintenance alert calls for operators to work with a Twin Commander Authorized Service Center within the next six months to undergo detailed visual inspections and either eddy current or liquid penetrant inspections of the affected area. Maintenance facilities are encouraged to report the results of the inspections to Twin Commander Aircraft by calling 919-956-4300, emailing [email protected], or by submitting the card attached to the alert.

Parts Availability Improving

Twin Commander reports that the transition of parts sales from the factory to new partner AAR is going well. The two teams have identified a number of process improvements and efficiencies, all of which is contributing to better lead times. “We’re making great progress,” said Value Stream Manager Bob Wilson. “I’m proud of the hard work and long hours the team has put in on-site with AAR to better serve Twin Commander owners and operators.” Staff have been working closely with AAR to improve lead times, and Wilson said parts availability is clearly better than it was just a few weeks ago. He expects that trend to continue as the teams work closely together over the next few months, and as AAR and the Twin Commander Factory Authorized Service Centers strengthen their relationships with AAR. “Ultimately we expect this to be a positive transition for owners and operators,” Wilson said. “AAR will do what it does best and fulfill parts quickly and efficiently, while Twin Commander can focus on engineering and other product support.”

Spring Weather Brings New Challenges

As temperatures around the country begin to climb, thunderstorms are becoming more prevalent, and upper-level icing is a concern. Now is the time to make sure your Commander’s systems are in top shape. Are your boots looking a little worse for wear? You’ll find them in stock at many service centers.

February/March 2023

Wilson Visits Service Centers

One of the most valuable aspects of a Twin Commander Service Center is a close connection to the factory. Technicians receive factory training, use factory approved methods, and are the exclusive providers of factory parts. The people make all that possible. Last week Twin Commander chief Bob Wilson got a chance to strengthen those connections with site visits to three Twin Commander Factory Authorized Service Centers. He spent time at Winner Aviation in Youngstown, Ohio, National Flight Services in Toldeo, Ohio, and Eagle Creek Aviation near Indianapolis. “Our fleet is only as strong as the people who support and maintain it,” Wilson said. “It was my pleasure to meet so many dedicated professionals who have the passion and expertise that make our community so strong.” Wilson said he was impressed by the facilities at each location, but more than that, it was the history of supporting Twin Commanders and the incredible depth of knowledge that really astounded him. “I have complete faith in our Service Centers to do what’s best for the operator, and I am excited to do our best for them from the factory.” You can find a full list of Factory Authorized Service Centers online.

In the latest issue of Flight Levels Online, out now, up your Garmin game by learning how to better program departures and arrivals, two of the more difficult functions of the box. Through a combination of in-flight experience and knowledge gained through reading and watching videos, you can become more comfortable in the buttonology, which leads to more consistent procedures, and ultimately safer operations. Read this story, and more in the latest issue.

An Airplane with a Story

You are obviously drawn to the Commander because of the performance, the range, the useful load, and the way it makes you feel when you fly it. But, we know you love the history and the lore of the airplane, too. There’s no denying that flying a descendant of one of the first certificated civilian twin engine airplanes, one that served as Air Force One, and of course, one that wowed audiences for years through the deft hands of Bob Hoover has a special place in aviation history. You can read the whole story in Dave Duntz’s fantastic book, Stars and Commanders: The Life and Vision of Ted Smith. Duntz had unrestricted access to Smith’s files, his unpublished memoir, and more. Through his research and dozens of first-hand accounts, he creates the ultimate story of the origins of the Aero Commander and its many subsequent iterations. Anyone who is a fan of the airplane will love the book, which can be purchased online.
