0310295 – Textron Aviation OEM Actuator Collar (Elevator Trim)
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 0310295 is a genuine OEM, flight-critical collar for the elevator trim tab actuator assembly. This precision-machined component is an essential part of the aircraft's primary pitch trim system. It is installed on the actuator's main screw assembly, typically adjacent to the chain sprocket, where it functions as a critical spacer and load-bearing retainer.
This collar ensures the precise alignment and spacing of the actuator's internal components, preventing axial movement and binding of the sprocket and bearings. The integrity of this component is essential for the smooth, reliable, and binding-free operation of the elevator trim system. Its failure or wear can contribute to excessive free play or jamming of the trim tab, a condition that is heavily regulated by FAA Airworthiness Directives (ADs) and can lead to a loss of aircraft control.
Key Features
Genuine Textron Aviation OEM Part: The only part certified and manufactured to the exact material specifications, heat treatment, and dimensional tolerances required for the trim actuator.
Flight-Critical Component: An essential component of the elevator trim system; its integrity is directly linked to the safe operation of the aircraft's primary pitch control.
Precision Machining: Machined to exceptionally tight tolerances to ensure a perfect fit, eliminating "slop" and ensuring smooth load transmission within the actuator.
High-Strength Material: Fabricated from a high-strength, wear-resistant metal alloy, engineered to withstand the continuous, high-cycle loads and vibrational environment of the flight control system.
AD & Service Bulletin Compliance: This part is a key component of the elevator trim actuator assembly, which is the subject of critical Airworthiness Directives (e.g., AD 2016-07-24) and Service Bulletins (e.g., MEB-27-02) related to hardware inspection and security.

Applications
Elevator Trim Tab Actuator Assembly: Serves as a critical retainer and spacer on the main screw assembly, often in conjunction with the actuator sprocket (e.g., P/N MC0310332) and bearings (e.g., P/N 0310297-1).
Flight Control System Repair & Overhaul: The certified component for use during the overhaul or repair of the elevator trim actuator.
Why Choose 0310295?
The elevator trim actuator is a "no-fail" system. The genuine Textron 0310295 is the only part guaranteed to meet the precise material and dimensional standards required for this critical, high-load, high-vibration application. Using a non-certified part introduces an extreme risk of improper fit or material failure, which can lead to the jamming of the elevator trim system. Given the known history of ADs related to this assembly, the use of a fully traceable, genuine OEM component is the only professional and airworthy choice.
The engineering principle behind the 0310295 collar is to serve as a hardened spacer and load-transfer ring within the actuator's mechanical drive. It is located on the main screw assembly alongside the drive sprocket. When the pilot (or autopilot) commands a trim change, rotational force is transferred via a chain to the sprocket. This collar acts as a fixed retaining component, ensuring the sprocket's force is applied correctly to the bearings and screw, and preventing the components from binding or "walking" along the shaft. Its hardened, precision-ground faces provide a durable, low-friction wear surface, ensuring that the actuator's rotational input is smoothly and accurately converted into the linear motion that moves the trim tab, even under the high aerodynamic loads experienced in flight.
Note: The 0310295 is a flight-critical component. Installation must be performed by a certified A&P/IA mechanic in strict accordance with the Textron Aviation maintenance manual and all applicable Airworthiness Directives (ADs) and Service Bulletins (SBs). Proper inspection, lubrication, and re-assembly procedures for the actuator are mandatory.
