MT-Propeller Entwicklung GmbH has received FAA Supplemental Type Certification of its “Quiet Fan Jet” five-blade scimitar composite propeller on the Twin Commander 690/695 series with either the Honeywell TPE-331-5 or Dash 10T engine. The installation is already EASA certified.

MT-Propeller President Gerd Muehlbauer says the installation offers a number of advantages over conventional metal props:

  • An approximate 10-percent reduction in takeoff distance (MTOW, SL, ISA conditions).
  • Slightly faster cruise performance (3 to 4 kts at MTOW and ISA).
  • Cooler ITTs during engine start up, therefore less engine wear and reduced risk of hot start.
  • Lighter than the original propellers by 8 kg (17.7 lbs) per propeller assembly.
  • A reduction in Cabin noise of between 3-5 dB(A).
  • The STC complies with strict German noise regulations for unrestricted airport operations in Germany and other European countries.
  • Serious ramp appeal.

The MT-Propeller has no life limitation, and is repairable in the event of FOD-related damage. The prop has bonded nickel alloy leading edges for erosion protection. The five-blade prop also provides near vibration-free propeller operation.

TBO is at 3500 or six years, with plans to increase that to 4000 hours or six years. The retail price for a pair of five-bladed, constant-speed propellers with feathering and nickel leading edges is $98,500.00 (including exchange for the existing propellers and spinner assembly). Freight from Germany and Installation are additional.

The STC Kit includes two five-blade full-feathering constant-speed propellers, spinner assemblies, slip ring assemblies, and deice kits.

Several Twin Commander factory-authorized service centers will have displays at the National Business Aviation Association Convention and Exhibition at the Las Vegas Convention Center October 10-12.

Banyan Air Service, based at the Ft. Lauderdale, Florida Executive Airport, will be at the Avfuel collection of service providers in Booth 4314 and the FXE booth, N924. Executive Aircraft Maintenance, based at the Scottsdale, Arizona, Municipal Airport, will be at Booth #11438 in the Central Hall, and National Flight, based at the Toledo, Ohio, Express Airport, will be in Booth C10836.

If you will be at the NBAA Convention and Exhibition, plan to stop by these Twin Commander Service Centers to see what they might offer in the way of service and parts support for your Twin Commander, and in the case of Banyan and National, FBO services when flying to KFXE or KTOL.


Hurricanes Harvey and Irma dealt some damaging blows to Houston, Texas, and Naples, Florida, where two authorized Twin Commander Service Centers are located, but fortunately both escaped major damage.

Global, located in the Tomball Jet Center at David Wayne Hooks Memorial Airport in northeast Houston, escaped the major flooding or damage that affected much of the Houston area, but the area surrounding the airport was flooded. Global was shut down for five days after Harvey because the water was high “all around the airport,” said Sherrie Ray, who along with her husband Doug own and operate Global. “It’s still slow going, but we are thankful we came through it okay,” she said.

Naples Jet Center at the Naples, Florida, Municipal Airport, took a near direct hit from Hurricane Irma that made landfall in Florida in early September with winds clocked at 143 mph at the airport. NJC had moved all the airplanes in its storage and maintenance hangars, and no staff were on site when the storm hit. The Category 4-strength winds destroyed the mesh doors on two large storage hangars owned by NJC, but no other significant damage was reported.

The company resumed operations several days after the storm. The two hangar doors will be replaced.


“All the news that fits” is an appropriate slogan for the hefty New York Times, but limited space in the Twin Commander eNews and Flight Levels magazine sometimes forces us to limit the photos or words accompanying a story. Well, to use another famous media slogan (this one from Paul Harvey), “the rest of the story” often can be found on Twin Commander Aircraft’s Facebook page.

For example, in last month’s eLetter we published a dramatic photo of a Shrike Commander in formation with an F-86 Sabre, P-51 Mustang, and T-28 Trojan taken during EAA’s 2017 AirVenture. The occasion was a tribute to the legendary Bob Hoover, who flew all of those aircraft in his post-war career.

We had more great photos of the formation, but no room in the eLetter to publish them, so they have been placed on Twin Commander’s Facebook page.

You can find lots of other interesting information and photos on the Facebook page, which has grown dramatically in popularity since it was launched two years ago—more than 1,000 people have “Liked” the page.
