9910333-1 – Textron Aviation OEM Engine Mount for Caravan Aircraft

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 9910333-1 is a genuine OEM, flight-critical engine mount, the primary structural frame engineered to secure the Pratt & Whitney Canada PT6A turboprop engine to the firewall of the Cessna 208 and 208B Caravan. This is not a simple bracket; it is a complex, precision-welded assembly fabricated from high-strength 4130 chromoly steel tubing. It is designed to bear the entire static weight of the engine and propeller, and to transfer the immense forces of thrust, torque, and G-loads safely to the airframe. As a genuine Textron OEM part, it guarantees the precise geometry, material strength, and weld integrity required for this fundamental structural application.

Key Features

• Primary Structural Component: Serves as the foundational structure that connects the powerplant to the airframe. Its integrity is absolutely essential for flight safety, as it handles all static and dynamic loads produced by the engine and propeller.
• 4130 Chromoly Steel Construction: Fabricated from aerospace-grade 4130 chromium-molybdenum steel tubing, renowned for its exceptional strength-to-weight ratio and excellent weldability. The entire assembly is normalized and stress-relieved after welding to ensure maximum strength and fatigue resistance.
• Precision Jig-Welded: Each mount is meticulously welded in a precision jig to ensure perfect alignment of all attachment points, including the firewall connection points and the receptacles for the engine's vibration isolators (shock mounts). This precise geometry is critical for proper engine alignment and drivetrain integrity.
• Corrosion-Resistant Finish: Coated with a durable, corrosion-resistant primer and/or topcoat. This protects the steel structure from the harsh, high-temperature, and corrosive environment of the engine compartment.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees conformance to the strict material, welding, and non-destructive testing (NDT) standards of the original aircraft Type Certificate.

Aircraft Compatibility

The 9910333-1 is the specified OEM engine mount for the world's most popular utility turboprop aircraft. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification.

• Primary Aircraft Models:
  • Cessna 208 Caravan
  • Cessna 208B Grand Caravan / Super Cargomaster

Applications

The 9910333-1 is a flight-critical assembly for several key scenarios:

• Aircraft Production & Repair: The factory-standard component for aircraft manufacturing and the only certified replacement for a damaged original mount.
• Mandatory Replacement Item: Must be replaced if found to have cracks, corrosion, or deformation from a hard landing, propeller strike, or other incident. It is subject to rigorous inspection schedules.

Why Choose 9910333-1?

The engine mount is the single most important structural connection on a single-engine aircraft. A failure of this component would be catastrophic. The Textron Aviation 9910333-1 is the only component certified by the manufacturer to provide the required strength and fatigue life for the Caravan. Using a genuine OEM part is the only way to ensure the mount has been built with certified materials, welded by certified technicians, and has passed the rigorous inspections required for a primary airframe structure. There is no substitute for the safety and airworthiness of a genuine Textron part.

The 9910333-1 engine mount is an example of a space frame or "truss" structure. It is designed using a series of interconnected steel tubes that primarily carry loads in tension and compression, which is the most efficient way to use the material. The specific angles and lengths of each tube are carefully calculated through finite element analysis (FEA) to safely distribute all engine and propeller loads into the four main attachment points on the aircraft's firewall. After welding, the entire structure undergoes a normalizing heat treatment process, which refines the grain structure of the steel in the heat-affected zones of the welds, relieving internal stresses and maximizing the strength and fatigue resistance of the entire assembly.

Note: This is a flight-critical primary airframe structure. Installation must be performed by a certified A&P mechanic in strict accordance with the current Textron Aviation maintenance manual. A full engine alignment check must be performed after installation. All mounting hardware should be replaced with new, specified parts during installation.
