Barry Mounts Specifications for Twin Commander Aircraft

Note: Turboprop models (690/695 series) require specialized multi-mount assemblies with six mounts per engine. All part numbers link to individual product pages with pricing and availability.

Twin Commander Aircraft Technical Overview

Early Piston Models: 500 Series Foundation

The Twin Commander 500 introduced the aircraft family with naturally-aspirated Lycoming O-540 engines, establishing the type's reputation for robust construction and reliable performance. The 500-A variant transitioned to Continental IO-470 fuel-injected engines, requiring different mount specifications to accommodate Continental's mounting architecture. These early models utilize the standard four-mount-per-engine configuration typical of horizontally-opposed piston aircraft.

Supercharged Evolution: 560/680 Series

The 560 series marked Twin Commander's evolution toward higher performance with geared and supercharged Lycoming engines. The 560-A through 560-F models utilized various configurations of GO-480 and IGO-540 powerplants, each requiring Barry part number 94110-40 mounts to handle the increased vibration characteristics of geared and supercharged operation. The 680 series further refined this approach with GSO-480 and IGSO-540 engines, providing increased power while maintaining the same mounting architecture.

The 680-FL and 680-FL(P) pressure-cabin variants, along with the 685 turbocharged models (GTSIO-520), continued using the 94110-40 mount specification, demonstrating Barry's design versatility across significantly different engine configurations and power outputs. The 720 model represented the final evolution of the piston-powered Commander line.

Turboprop Revolution: 690/695 Series

The introduction of Garrett TPE-331 turboprop engines with the 690 series fundamentally changed Twin Commander's market position and mounting requirements. Unlike piston engines requiring four symmetrical mounts, turboprop installations utilize a specialized six-mount system with different mount types at various locations around the engine. The 690/690A/690B models with TPE-331-5-251K and -252K engines require five distinct Barry part numbers in specific quantities: 92670-02, 92670-03, 92670-08, 92670-21 (quantity 2), and 92670-23.

Later 690C/690D variants with the upgraded TPE-331-5-254K engine, along with the 695/695A/695B series (TPE-331-10), utilize a revised mount kit consisting of parts 93395-02, 93395-06, 93395-25, 93395-27 (quantity 2), and 93395-29. This configuration accommodates the different mounting architecture and increased power output of these advanced turboprop variants.

Engine Mount Design and Function

Twin Commander engine mounts must isolate the airframe from engine vibration while securely transferring thrust loads and supporting engine weight. The piston models' four-mount system creates a stable platform for the horizontally-opposed engines' reciprocating forces, while the turboprop configurations' six-mount arrangement provides the multiple attachment points necessary for the turbine engine's different load distribution and mounting geometry.

Barry Mounts achieve this through precision-manufactured elastomeric elements bonded to metal hardware, providing controlled deflection under load while maintaining structural integrity. The different part numbers across the Twin Commander range reflect specific requirements for mount stiffness, load capacity, and geometry tailored to each engine type's unique characteristics. All configurations maintain FAA/PMA and EASA Part-21 certification throughout their service life.
