Twin Commanders are known for their segment-leading fuel efficiency, wide cabins and long-haul performance. Since the first production of aircraft in the 1950s, there have been many model variations. Over time, the Twin Commander has evolved with improved performance and capacity, additional features, improved design, and new power engines.
Originally designed in 1959 and certified in 1965, the TPE331 was Honeywell’s first turboprop engine. With over 13,000 engines delivered today and over 122 million hours of flight time, the TPE331 is one of the most reliable and proven turboprop engines in the world. In 1973, National Flight Service (NFS) became the Twin Commander Service Center, the second oldest existing service center. In 1983 they began developing the TPE331 engine, and in 2005 they became Honeywell’s first licensed heavy-duty center. To date, NFS has established itself as the world’s largest independent TPE331 refurbishment and repair facility, operating engines in more than 65 countries.
In August 2018, Herb Harvey purchased NFS. He has extensive maintenance experience, especially for helicopters. Honeywell was awarded NFS as the 2019 Honeywell Business Aviation Channel Partner of the Year and Honeywell Service Center / 2019 MRO of the Year because of Harvey’s leadership in just one year. These are global awards that recognize partners who have achieved outstanding performance throughout 2019. These awards are for the best channel partners, who act in line with Honeywell’s behavior, rather than the top channel partners. We support clients all over the world. The aviation industry and around the world.
In July of this year, Honeywell appointed National Flight Service as the only licensee in the world to switch from Twin Commander -5 to -10T. This is a perfect combination as NFS is also a Twin Commander Service Center.
NFS has been in business for 58 years and offers several TPE331 maintenance and repair services, such as:
- TP331 Overhaul or CAM w/ New Honeywell Parts and Honeywell-Authorized Components
- Engine vibration analysis
- Engine corrosion repair, treatment, and repainting (green)
- Complete engine/control rigging
Trust the power of your TPE331 engine of your Twin Commander to NFS and be sure that your aircraft is up to speed.
