Bell 212 & 412/EP

Lightweight Tailboom

More payload. Lower maintenance. Greater efficiency.

StandardAero’s Lightweight Tailboom modification STC replaces the original composite baggage compartment structure with a durable, sheet-metal semi-monocoque design, delivering meaningful weight savings, improved structural strength, and reduced long-term maintenance costs for the Bell 212 and 412 helicopter operators.

Designed specifically for operators who demand higher payloads, lower operational costs, and improved reliability, this upgrade transforms an again, maintenance-intensive area of the aircraft into a stronger, lighter, and more economical solution.

The STC is currently approved by, FAA, EASA and TCCA.

Why upgrade?

Increase your Useful Load

By removing composite honeycomb components and optimizing the aircraft’s center of gravity, this modification reduces empty weight and increases your available payload.

That’s more passengers, more cargo, or more mission capability on every flight.

Lower Maintenance Costs

Traditional honeycomb baggage compartments are vulnerable to corrosion, moisture intrusion, and delamination, especially in harsh environments such as salt water or high-heat operations.

Our all-metal design eliminates these common issues, helping you avoid costly repairs and downtime.


Spend less time in the hanger and more time flying revenue missions.

Stronger, Smarter Structures

The upgraded semi-monocoque tailboom uses metallic skins, frames, bulkheads, and reinforced longerons to improve durability and load-carrying capability.

Built for longevity and reliability in demanding operations.

Better Operational Performance

Weight savings translate directly into operational benefits:

Increased payload & revenue potential

Improved fuel efficiency

Enhanced performance margins

Ideal for utility, offshore, firefighting, EMS, and other mission-critical operators.

Seamless Integration

The modification is engineered to work with your existing systems, minimizing additional costs and simplifying installation.

Compatible with:

Optional upgrades can be incorporated during installation for even greater weight savings and performance.

Designed for Bell 212, 412 & 412EP Helicopter Operators

Because the baggage compartments are identical, this modification is fully applicable to both aircraft types, providing a consistent, proven solution across your fleet.
