Aerospace legacy parts manufacturing and support special Ontic has completed its acquisition of Firstmark Corp., the parent of Twin Commander, Aircraft Belts, and Firstmark Aerospace, among other companies.

Firstmark provides a range of engineering, propriety components, and subsystems for the aerospace and defense industries. Its portfolio expanded in the general aviation realm with the 2008 acquisition of Twin Commander, which has supported and provided parts and services for the Aero Commander/Twin Commander families since production ceased more than two decades ago.

Under the new ownership, Brian Harbaugh, a long-time senior manager at Twin Commander, has taken the role of acting business unit director of Twin Commander and Aircraft Belts. “Ontic is a great fit for Twin Commander. As a company dedicated to legacy product support, the expertise and resources Ontic brings will help propel Twin Commander long into the future,” he said.

Twin Commander will continue to focus on strengthened Twin Commander customer support through its factory authorized service center network, engineering upgrades, and opportunities for Twin Commander owners and operators to network, Harbaugh said, adding he plans to reach out to the Twin Commander community over the next few months to discuss the plans for the Twin Commander family.

For Ontic, the acquisition adds about 70 workers and expands the presence of Chatsworth, California-based Ontic in the East Coast with facilities in Creedmoor, North Carolina, and Plainview, New York. These sites complement Ontic’s locations in Cheltenham, UK, and Singapore, in addition to Chatsworth, Ontic said.

“The acquisition confirms Ontic’s commitment to support our customers by adding manufacturing and MRO Service capabilities on the U.S. East Coast,” said Gareth Hall, president and managing director of Ontic. “Firstmark is an ideal fit for Ontic with their high-quality portfolio of products supporting civil and military aircraft.”
