S1026CG100 – Textron Aviation OEM Exhaust Ejector Clamp Kit
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation S1026CG100 is a genuine OEM, flight-critical Exhaust Ejector Clamp Kit for the Cessna 208 Caravan. This is a heavy-duty, structural component designed to securely fasten the engine's exhaust ejector fairing to the primary exhaust stack. Weighing over 11 pounds, this is not a simple band clamp but a robust, multi-component kit engineered to withstand the extreme temperatures, high-frequency vibrations, and aerodynamic loads of the Pratt & Whitney PT6A turboprop engine's exhaust system.
The primary function of this clamp kit is to maintain the precise alignment and structural integrity of the exhaust ejector, which is critical for proper engine cooling and aerodynamic performance. A failure of this component could lead to the separation of the exhaust ejector, causing catastrophic damage to the empennage or flight controls. This kit, which supersedes older part numbers S1026BG100 and S1026CG10.90X, includes all the necessary, certified hardware to ensure a safe and airworthy installation as specified by the manufacturer.
Key Features
Genuine Textron Aviation OEM Kit: The only certified, factory-specified kit for this application, guaranteeing perfect fit, form, and function.
Flight-Critical Structural Component: Engineered to secure the heavy exhaust ejector assembly against extreme vibration, heat, and aerodynamic loads.
Complete Hardware Solution: A comprehensive kit containing all necessary clamps, fasteners, and other specified hardware for a complete and airworthy installation.
High-Temperature Materials: All components are manufactured from aerospace-grade, high-temperature-resistant alloys to prevent failure, creep, and corrosion in the harsh exhaust environment.
Direct Supersedure: This is the current, factory-approved replacement for older part numbers, including S1026BG100.

Why Choose S1026CG100?
The exhaust ejector clamp is a "no-fail" component. The failure of a non-certified or "will-fit" part in this high-vibration, high-temperature environment can lead to the liberation of the entire 11+ pound ejector assembly in flight, striking the tail and causing a loss of control. The genuine Textron S1026CG100 kit is the only part guaranteed to be made from the correct materials, with the proper heat treatment and quality control required to withstand these severe operational stresses. For a component this critical, there is no substitute for the OEM part.
The engineering principle behind the heavy-duty design of the S1026CG100 kit is the management of high-frequency vibration and thermal expansion. The Pratt & Whitney PT6A engine and propeller combination produces a wide spectrum of vibrations that are transmitted directly to the exhaust stack. This kit is designed to act as a tuned mass damper and a rigid structural tie. The sheer mass (11.4 lbs) of the clamp assembly helps to absorb and damp resonant frequencies, preventing them from creating the high-cycle fatigue that can crack and fail exhaust components. Furthermore, the clamp and bolt system is engineered to maintain a constant, high clamping force even as the dissimilar metals of the exhaust stack and ejector expand and contract at different rates during the engine's thermal cycles. This ensures the joint remains rigid, secure, and free from the fretting wear that would otherwise be caused by microscopic movements.
Note: The S1026CG100 is a flight-critical hardware kit. Installation must be performed by a certified A&P/IA mechanic in strict accordance with the Textron Aviation Cessna 208 Series Maintenance Manual. All torque values specified in the manual must be adhered to using a calibrated torque wrench. Proper installation and torquing are essential for preventing catastrophic component failure.
