Ametek Aerospace & Defense said it is buying two privately held aerospace businesses that serve the business jet, regional jet and helicopter markets. Financial terms of the two deals were not disclosed. The Paolo, Pa.-based Ametek said the acquired companies –– Advanced Industries, Inc., and B&S Aircraft Parts and Accessories –– are expected to have annual sales near $25 million. The company also expects the deals to “strengthen our position in the aircraft power management and third party maintenance, repair and overhaul services (MRO) markets.” “These businesses serve the expanding business and regional jet markets, have well-established relationships with the key aircraft manufacturers and provide AMETEK with a strategic footprint in Wichita. They each have an excellent reputation within the aerospace industry and offer an excellent fit with our existing aerospace business,” said Ametek Chairman and Chief Executive Officer Frank S. Hermance. Advanced Industries manufactures starter generators, brush and brushless motors, vane-axial and centrifugal blowers for cabin ventilation, and linear actuators for the business jet, light jet and helicopter markets. B&S Aircraft Parts & Accessories provides third party MRO services, primarily for starter generators and hydraulic and fuel system components, for a variety of business aircraft and helicopter applications.
