SR01406LA – Teledyne Gill Battery STC Kit for Bell 206 Helicopters and 7641-20 Batteries
Available now on the Airparts.aero Marketplace.
Overview
The Teledyne Gill SR01406LA is a complete, FAA-approved Supplemental Type Certificate (STC) kit that authorizes the replacement of the original, maintenance-intensive Nickel-Cadmium (Ni-Cad) battery with a high-performance Gill 7641-20 sealed lead-acid battery on the iconic Bell 206A and 206B JetRanger helicopters. This comprehensive kit provides the official STC authorization, detailed engineering drawings, and all necessary, precision-engineered hardware to perform this critical battery system upgrade. By converting to Gill's modern, sealed VRLA/AGM technology, this STC offers a significant improvement in operational reliability, a dramatic reduction in maintenance costs, and an enhancement in overall safety.
Key Features
- Complete, Certified Modification Package: This is not just a single part, but a complete, turnkey STC kit containing the legal FAA authorization, installation instructions, and all required hardware to modify the helicopter in an airworthy manner.
- Enables Modern Battery Technology: Facilitates the upgrade to the Gill 7641-20 Valve-Regulated Lead-Acid (VRLA) / Absorbed Glass Mat (AGM) battery. This provides excellent starting performance for the turbine engine, is maintenance-free (no watering), and eliminates the hazardous materials and thermal runaway risks associated with Ni-Cad batteries.
- Custom-Engineered Battery Tray: The kit includes a custom-fabricated battery box or tray, designed with the precise dimensions and structural integrity to securely hold the 7641-20 battery in the airframe, replacing the original Ni-Cad battery container.
- Simplified Installation: Provides all necessary brackets, fasteners, and wiring/connector assemblies to ensure a straightforward installation with minimal modification to the existing airframe structure, reducing aircraft downtime.
- Reduced Maintenance Costs: Eliminates the expensive and time-consuming capacity checks, deep cycling, and re-watering procedures required for Ni-Cad batteries, offering a significantly lower total cost of ownership and reducing maintenance-induced downtime.

Applications
The SR01406LA STC kit is the all-in-one, certified solution for a major aircraft system upgrade:
- Battery System Modernization: The primary application is to upgrade from older, hazardous, and maintenance-intensive Ni-Cad batteries to modern, high-performance sealed VRLA batteries.
- Improving Dispatch Reliability: Sealed lead-acid batteries provide more predictable performance and are less susceptible to the sudden failures that can affect Ni-Cad batteries, improving on-time performance for commercial operators.
- Enhancing Safety: Eliminates the risk of a thermal runaway event, a dangerous and well-documented hazard associated with Ni-Cad battery chemistry, which can lead to an in-flight fire.

A Supplemental Type Certificate (STC) such as SR01406LA represents a significant engineering undertaking. Teledyne Gill must prove to the FAA that their battery system modification is at least equivalent in safety and performance to the original type-certificated design. This involves extensive testing, including structural load tests on the new battery box to withstand helicopter vibration and G-loads, electrical load analysis to ensure the aircraft's starter-generator and charging system are compatible with the VRLA battery, and development of an Approved Flight Manual Supplement (AFMS). The AFMS provides the flight crew with the necessary operating procedures and limitations for the new system. The Instructions for Continued Airworthiness (ICA) provides the maintenance technicians with the required inspection and service procedures. The purchase of the kit grants the operator the right to use this proprietary, pre-approved data to legally perform the modification.
