The company holds FAA, EASA, DGCA (India), and ANAC (Brazil) certifications as an Authorised Repair Station, enabling it to service aircraft for operators across North America, Europe, South Asia, and South America.

NFS specialises in Honeywell TPE331 turboprop engine overhaul and repair, holding the status of a Honeywell-authorised Turboprop Engine Core BGA Channel Partner of the Year and Service Center/MRO Channel Partner of the Year.

NFS is also an authorised Twin Commander Service Centre, combining airframe and engine expertise for this aircraft type.
Beyond the TPE331 specialisation, NFS offers a broad range of airframe services including scheduled and unscheduled maintenance inspections, structural repairs, airframe modifications, custom interior installations, and avionics repair and installation. The company's customer base encompasses corporate aviation operators, regional airline operators, government aircraft fleets, and privately owned aircraft. NFS provides bilingual service in English and Spanish to serve Latin American operators. TPE331 Engine training is offered as a formal programme for airline maintenance technicians and operators.
