MC1414104-54 - McFarlane Aviation FAA-PMA Seat Roller Bushing

MC1414104-54 – McFarlane Aviation FAA-PMA Seat Roller Bushing

Available now on the Airparts.aero Marketplace.

Overview

The McFarlane Aviation MC1414104-54 is a high-performance, FAA-PMA certified seat roller bushing, engineered as a superior replacement for the original Cessna part number 1414104-54. This precision-machined component is a critical part of the seat adjustment mechanism, serving as the low-friction interface between the seat roller and its axle or pin. Its function is to allow the pilot and passenger seats to slide smoothly and precisely along the seat tracks for proper positioning. Worn or deteriorated bushings are a common cause of seats that are difficult to move, feel loose, or jam in their tracks.

McFarlane has engineered this bushing from a proprietary, advanced self-lubricating polymer that offers significantly improved wear resistance and a lower coefficient of friction compared to the original OEM material. This results in a smoother seat adjustment action and a dramatically longer service life. As an FAA-PMA approved part, it has been rigorously tested to demonstrate that its performance and quality are equal to or better than the original, making it the premier choice for restoring the function and feel of your aircraft's seating system.

Key Features

• FAA-PMA Certified: A fully certified, airworthy replacement for Cessna P/N 1414104-54, approved for a wide range of aircraft.

• Superior Self-Lubricating Polymer: Fabricated from an advanced, proprietary polymer (e.g., PTFE-infused acetal) that provides exceptional wear resistance and eliminates the need for lubrication.

• Low-Friction Performance: The self-lubricating material ensures a smooth, consistent, and low-effort seat adjustment action.

• Precision Machined: Machined from extruded rod stock to exacting dimensional tolerances for a perfect, slop-free fit and optimal performance.

• Enhanced Durability: Engineered to outlast the original component, reducing maintenance frequency and improving the feel of the seat mechanism for years to come.

Applications

• Seat Adjustment Mechanism: Provides a low-friction, high-wear pivot and bearing surface for the rollers in the fore-and-aft seat adjustment system.

• Maintenance & Restoration: A key component for eliminating looseness ("slop") and restoring the smooth, positive action of the aircraft's seats.

Why Choose MC1414104-54?

While a simple bushing may seem like a minor component, its performance directly affects pilot comfort and safety. A worn bushing can make it difficult for a pilot to achieve the correct seating position for proper rudder pedal and control access. More critically, excessive looseness in the mechanism can affect the positive engagement of the seat's primary locking pins in the seat rail. The McFarlane MC1414104-54, with its advanced self-lubricating polymer, not only restores the smooth action of the seat but also provides a longer-lasting, more durable solution than the original part. With full FAA-PMA certification, you are guaranteed a component that is both airworthy and superior in performance.

The superior performance of the MC1414104-54 bushing is rooted in the tribological properties of its advanced polymer composite material, such as PTFE-infused acetal. This material is not merely coated with a lubricant; it is a homogenous composite where microscopic fibrils of Polytetrafluoroethylene (PTFE) are evenly dispersed within a high-compressive-strength acetal copolymer matrix. During operation, as the bearing surface undergoes microscopic wear, it constantly exposes new PTFE particles. This process, known as self-lubrication, creates and perpetually renews a low-friction film between the bushing and the metal pin. This eliminates the need for external grease, which would attract dirt and grit that can jam the mechanism. The acetal matrix provides the robust mechanical strength to support the occupant's weight without deforming or creeping over time, resulting in a bushing with an extremely low coefficient of friction and a very high pressure-velocity (PV) limit.

Note: The MC1414104-54 is a flight safety-related part. Installation must be performed by a certified A&P mechanic in accordance with the Cessna maintenance manual. It is highly recommended to replace all bushings on a seat at the same time to ensure even wear and smooth operation. At the time of replacement, the seat rollers, pins, and seat tracks should be thoroughly inspected for wear, damage, or corrosion.
