In September 2021, FEAM AERO expanded its footprint internationally with the acquisition of BOSA, a globally approved aircraft maintenance provider with four line stations across the UK and Germany. FEAM also added two additional BOSA line stations to our portfolio in early 2022, increasing our international footprint from four to six locations.
Headquartered in Cheshire, England, BOSA provides aircraft line maintenance across all Boeing and Airbus fleet types, and component repair to over 5,000 aircraft parts for a multitude of airline customers. Rounding out their capabilities, BOSA provides AOG recovery services throughout the UK and Europe, allowing us to expand our On-Wing AOG Repairs Team further into the region.

CAPABILITIES
BOSA can also assist with the design and implementation of onsite oxygen filling equipment which negates the need for costly hazardous goods transport. Staff training can also be included in your
Destructive manufacturing techniques, such as machining, result in the removal of large amounts of bulk material often meaning operations can result in over 90% waste material. For high-value aerospace components manufactured in expensive metals, material buy-to-fly ratios of 15:1 are not uncommon (15 kg of material to a produce1 kg component)
Utilizing our “we care to repair” scheme typically saves 50% against the cost of new filters whilst reducing lead-times and environmental impact. Potentially hundreds of thousand dollars are realistic against a modern fleet.
Our capabilities currently include Water Separators, Waste Level Transmitters, Level Sensors, Drain Valves, Vacuum Generators and Vacuum Toilet Assemblies.
OEMS supported include: Zodiac, Leonardo, Sirio, Airsignia, Diehl.
BOSA covers all major OEM’s including B/E, Dreissen (Zodiac), Ipeco , Sell and Rumbold. We can service boilers on a ship shop ship basis in only 4 days, meaning BOSA can support an aircraft’s scheduled check “ship shop ship”.
During 2013 BOSA was instrumental in the launch of a PMA solution for Heating Elements found in several models.
Operators have enjoyed a saving of up to 60% and this, coupled with regular “de-scaling”, has seen major improvement to MTBF’s.
BOSA is an approved repair vendor for Switlik General Aviation and Marine Safety Devices and can supply their range of Life Preservers and Aviation Life Rafts.

In March 2022, we extended our European reach even further with the acquisition of Northern Aerotech, bringing our total European line station count to 12 locations for a total of 42 global line stations. The acquisition represents a natural progression of FEAM’s tremendous growth throughout Europe on the heels of the successful addition of BOSA.
capabilities
Northern Aerotech has over 30 years of experience in heavy line maintenance and has the technical capability with multiple Boeing and Airbus fleet types. They also hold EASA Part 145 certification.
