Capabilities
Special Mission Modifications
Avcon designs and certifies purpose-built aircraft modifications that expand what your platform can do — wherever the mission takes you.
Mission-Ready Solutions
Purpose-Built for the Mission
For more than 50 years, Avcon has translated demanding mission requirements into certified airframe solutions. Our engineers integrate sensors, communications, and structural systems with the precision your operation demands.
Avcon modifies fixed-wing platforms to carry electro-optical/infrared (EO/IR) sensor payloads, datalinks, and mission-management systems. We engineer nose radomes, belly pods, and wing stations that maintain airworthiness while maximizing sensor field of view and line-of-sight performance.
Precision geospatial data starts with a stable, well-certified camera platform. Avcon installs camera ports, vibration-isolated sensor mounts, and mission-power systems that meet the tight positional accuracy requirements of photogrammetric survey, LiDAR, and hyperspectral imaging operations.
Coastline protection, fisheries enforcement, and search operations require aircraft modified for extended overwater endurance. Avcon integrates surface-search radar, extended-range fuel systems, and direction-finding equipment on turboprop platforms.
Avcon modifies platforms for SAR missions with enhanced navigation, communications, and long-range endurance. Modifications include HF radio installations, night-vision compatible lighting, cargo-door provisions, and reinforced observer windows — all fully FAA-certified.
Research agencies rely on highly modified aircraft to collect atmospheric, ecological, and geophysical data. Avcon supports these programs with specialized sensor ports, atmospheric sampling system installations, and mission-power architectures.
Law enforcement aviation units depend on purpose-configured aircraft to conduct surveillance, track targets, and coordinate ground forces. Avcon installs observation windows, thermal imaging systems, digital downlink equipment, and extended-range fuel systems — all maintained under our FAA Part 145 Repair Station authority.
Platform Flexibility
Avcon holds STCs across Beechcraft, Cessna, Learjet, Piper, Dassault, and other platforms. If your mission requires a different aircraft type, our engineering team can evaluate new platforms for STC development.

End-to-End Integration
The Architecture Behind the Mission
Modern mission aircraft are complex systems of systems. Avcon engineers design the integration architecture, manage the interfaces between subsystems, and carry the program through FAA certification — delivering a fully capable, airworthy aircraft.
01
Avionics & Communication Systems
Avcon installs, interconnects, and certifies avionics suites ranging from glass cockpit upgrades to full mission-management displays. We integrate VHF/UHF radios, satellite communication systems, data links, and navigation architectures that meet the specific communication requirements of each mission role.
02
Sensor Integration & Payload Management
Sensor performance depends as much on installation quality as sensor capability. Avcon designs mechanical and electrical interfaces for EO/IR turrets, radar systems, camera pods, and atmospheric sampling equipment — ensuring structural integrity, thermal management, and signal quality are maintained across the flight envelope.
03
Electrical Power Architecture
Mission payloads place significant demands on aircraft electrical systems. Our engineers design supplemental power generation, power distribution, and load management systems that support high-demand mission electronics without compromising aircraft electrical system certification or reliability.
04
Data & Network Integration
Situational awareness depends on data moving reliably between sensors, displays, and ground stations. Avcon integrates MIL-STD and commercial data buses, Ethernet mission networks, and encrypted data-link systems — tested and certified to operate in the airborne environment.
05
Structural Modifications & Airframe Integration
Every system integration starts with an airframe that can carry the load. Avcon's structural engineers design and certify belly pods, antenna fairings, cargo provisions, door modifications, and custom equipment racks — providing the physical foundation that mission systems require.
Requirements In. Certified Aircraft Out.
Avcon works from customer mission requirements, translates them into an engineering design, coordinates with FAA Designated Engineering Representatives (DERs), and delivers a Supplemental Type Certificate that allows the modification to be reproduced across an entire fleet.
