DESCRIPTION
The **Sky-Tec 149-12HT-H2 Starter** is a high-torque, lightweight geared starter designed for eligible Robinson Helicopter applications. Part of the **Sky-Tec HT Series**, it operates on a 12-volt electrical system and is configured for engines equipped with a **149-tooth starter ring gear**.
The starter features a left-hand solenoid position and a self-resetting **Kickback Protection System (KPS) clutch**. Its internal gear drive multiplies motor torque, while the lightweight, direct-mounting design supports efficient engine starting.
FAA-PMA eligibility includes applicable Robinson R22 and R44 helicopter models. The eligibility record references **P/Ns 149-12HT-H, BC315-100-2 and MZ-4224**. Compatibility must be confirmed against the exact helicopter model, engine installation, installed starter part number and applicable maintenance documentation before ordering.
