Piper Chieftan: Barry Mounts Aircraft Engine Mounts & Vibration Isolators

Barry Mounts are premium vibration isolation products manufactured by Hutchinson Aerospace (formerly Barry Controls) and widely used in aviation. In aircraft applications, Barry Mounts are designed to isolate engines, avionics, and other critical components from harmful vibrations during flight. These mounts use engineered elastomers to absorb vibration energy, helping to reduce structural fatigue, noise, and wear on components. Barry Mounts are trusted across general aviation, business aviation, and OEM platforms to enhance performance and reliability.

Vibration isolators like Barry Mounts play a critical role in maintaining structural integrity, reducing maintenance costs, and ensuring passenger comfort. Aircraft engines and equipment generate constant vibration, which can degrade avionics accuracy, cause metal fatigue, and create cabin noise. Vibration isolators absorb and dissipate this energy, preserving the aircraft frame, protecting sensitive electronics, and enhancing long-term safety. In doing so, they help operators extend service life and reduce repair frequency.

Yes. Barry Mounts are engineered to perform reliably in extreme temperature environments common in aviation. From high-altitude cold to the elevated heat of engine compartments, these vibration isolators maintain their performance and structural integrity. Their silicone elastomer compounds are specially formulated to withstand thermal stress without degrading or losing elasticity. This makes them a dependable solution for aircraft operating in diverse climates and challenging flight conditions.

By minimizing engine and airframe vibrations, Barry Mounts significantly improve in-flight comfort for both pilots and passengers. Reduced cabin noise and smoother ride quality help prevent fatigue during long flights, allowing pilots to remain focused and alert. Vibration control also protects avionics and flight controls from interference or degradation, contributing to operational precision. Barry Mounts support both comfort and confidence in the cockpit.

Aircraft engine mounts from Barry Mounts should be visually inspected during routine maintenance and thoroughly evaluated at scheduled intervals, such as annual inspections. Factors like flight frequency, environmental exposure, and aircraft type can affect inspection timing. Operators should follow the aircraft maintenance manual (AMM) and Hutchinson’s guidelines for specific mount models. Early detection of wear, cracking, or deterioration helps avoid structural damage and ensures continued airworthiness.

Barry Mounts for piston-powered aircraft typically consist of two elastomer-bonded metal assemblies and a spacer. The elastomer absorbs vibration, while the metal washers provide structural security and a fail-safe in case of elastomer damage. The spacer helps preload the elastomer during bolt torquing, optimizing the mount’s vibration control properties. Some models include integrated shims to support engine weight and enhance ground stability. This robust design ensures safety and consistent performance in demanding aviation environments.

The shelf life of Hutchinson Aerospace rubber components depends on the compound used and how the item is stored. Under MIL-HDBK-695 and ISO-2230 standards, shelf life can range from 3 years (for natural rubber) to 20+ years (for silicone or EPDM). Proper storage – between 40°F and 80°F (4°C to 27°C), away from ozone, sunlight, and humidity – helps preserve elastomer properties. Hutchinson products are typically marked with an embossed cure date to support inventory management and stock rotation.

Yes! PJi ships Barry Mounts engine mounts with an FAA 8130-3 tag to certify airworthiness and regulatory compliance. This form verifies that the product has passed all applicable quality assurance tests and meets FAA standards. It is essential for aircraft owners, MROs, and installers requiring traceable, certified aviation parts. The 8130-3 is included with your shipment and can also be retrieved through your PJi online account for added convenience.

Barry Mounts are used across a broad range of aircraft platforms, including general aviation piston aircraft, business jets, military aircraft, and helicopters. They are especially common in engine installations, avionics trays, and accessory equipment that must be shielded from vibration. Their versatility and reliability make them ideal for OEM use, upgrades, and aftermarket retrofits. Whether you're maintaining a Cessna 172, Beechcraft King Air, or Robinson R44, there's likely a Barry Mount designed to fit.

Yes! Vibration isolation provided by Barry Mounts helps reduce cabin noise by preventing engine and airframe vibrations from traveling through the structure. This makes for a quieter, more pleasant flying experience, particularly in light aircraft where noise levels can be high. Isolating vibration at the engine mount and avionics tray level reduces both audible and mechanical noise. Pilots and passengers benefit from better communication clarity and reduced fatigue during longer flights.
