Avcon Industries, Inc. has over 200 FAA-Approved Supplemental Type Certificates for various aircraft modifications. Many of these are for performance, safety, and functionality enhancements that can keep legacy aircraft flying, reduce costs, and / or improve the cabin experience.
This page is a list of the most popular Avcon performance modifications. For a full list of Avcon modifications, see our list of FAA Approvals and contact us at (316) 284-2842.
| Mod Type | Description |
|---|---|
| Aerodynamics | Stability & Weight Increase |
| Flight Range | Fuel Capacity Expansion – R/X Mod |
| Avionics | Installations & Overhauls |
| Noise Suppression | Avcon Hushkit for CJ-610 |
Avcon Delta Fins | For Learjet 30 Series
Avcon Fins interact with the vertical stabilizer to create positive stability in all three axes, and reduce drag by smoothing airflow around the tail cone area. The increased dispatch reliability and the enhanced stability (both in the landing phase and at high altitude) give the aircraft a solid and predictable handling profile.
At cruise airspeeds, Avcon Fins are aligned to provide aerodynamic stability when the aircraft attempts to stray from the intended line of flight (e.g. during turbulence). This “self-correcting” feature controls yaw and helps keep the aircraft on the step for optimal range performance. During landing and other low-speed maneuvers, Avcon Fins eliminate divergent dutch roll tendencies by providing additional lift and directional stability. The Avcon Fins eliminate the dispatch requirement for yaw dampers in Learjet 35 and 36 airplanes.
Increased Fuel Range | For Learjet 30 Series
The Avcon R/X Range Extension extends the tip tanks by 36 inches, making room for an additional 750 pounds of fuel. This provides a significant improvement to the standard Learjet 30-series flight range.
The R/X mod requires Avcon Fins and can include Avcon weight-increase packages.
Custom Avionics Installations
Avcon Industries offers custom avionics installations for various aircraft. These installations replace outdated parts and systems, extending the aircraft service life and improving performance. Two of our most popular avionics installations are RVSM and ADS-B equipment installations.
The Avcon RVSM installation allows the equipped aircraft to fly in RVSM airspace. All components are installed with new wiring and plumbing. If necessary, your existing autopilot computer may be inspected and repaired by an outside vendor.
Avcon provides a cost-effective ADS-B compliance solution for legacy Learjets. The STC also allows for addition of ADS-B(In) capabilities. Call Avcon at (316) 284-2842 for your ADS-B Compliance Solution.
Noise Regulation Compliance | For Learjet 20 Series
Consisting of a multi-lobed configuration nozzle and fairing, the Avcon hush kit passively controls the jet flow for an optimum noise reduction. Avcon hushkits satisfy noise regulation requirements and create a quieter cabin experience.
The Avcon noise suppressor, as approved in FAA STC No. ST01733WI, permits Lear 20 series aircraft to comply with the FAA regulations that will ground your Learjet if the stage 3 noise requirements are not met. Avcon Noise Suppressor only requires 3-7 days for complete installation, and will keep your Learjet flying for years to come.
