Schweizer 300CB

A Performance-Oriented Training Helicopter

With the debut of the Model 300CB, Schweizer Aircraft introduced the most versatile, reliable and performance-oriented piston training helicopter available in the world today. Most notably, the 300CB provides many commercial training operators with the lowest life cycle cost of any current production helicopter. The benefits are improved training and safety at a lower cost to the operator.

Specifically developed for the commercial helicopter training market, the Model 300CB retains all the superb flight handling, reliability and safety characteristics of the Schweizer Model 300C. The 300CB is designed to perform and made to last. It features:

Responsive handling characteristics with precise, vibration-free flight control forces.
Exceptional safety margins and large power reserve.
Excellent autorotation characteristics.
Designed-in crashworthiness features second to none.
Spacious cockpit and large useful load.
Field-replaceable components for easy maintenance.
Inspection and maintenance schedules optimized for less down time and lower operating costs.

The Model 300CB is powered by a Lycoming HO-360-CIA engine witha 2000-hour MTBO and rated at 180 continuous horsepower. With a gross weight of 1,750 pounds, the 300CB yields 662 pounds of payload. Translated into profitable economics, two 225 lb. pilots, with a full standard fuel tank of 35 gallons, can fly 3+ hours without refueling. That's a handy combination of performance and economy rolled into one very desirable package.


An Abundance Of Amenities
Performance is just part of what makes the Model 300CB attractive to the serious pilot. The 300CB is a workhorse with amenities. Standard features include:

Conventional Dual Controls
Equipped for Day and Night Training
Bendix King KY96A Comm
Bendix King KT76A Transponder
ACK A-30 Blind Encoder
Switchable Hot Mic Intercom
Heavy Duty Skid Shoes
Night Lighting
Right-hand Pilot-in-Command


Optimized For Training
The 300CB was designed to incorporate the many advantages of the Model 300C butat a lower cost. Over 100,000 students have learned to fly in Model 269 Series helicopters(TH-55, 300C and 300CB) which are generally accepted as the finest piston-powered training helicopters in the world.

The 300CB was designed to optimize training effectiveness. Attention to detail makes the cockpit both pleasing to the eye and convenient for the pilots. Its spacious cockpit and four inches of pedal adjustment help make pilots of nearly any size comfortable when seated. The use of a conventional helicopter control system facilitates pilot transition into other helicopters. Responsive handling characteristics provide pilots with smooth, vibration-free stick forces which facilitate learning. The cyclic control is well balanced under all flight conditions, which makes flying the 300CB a true pleasure and a great foundation for students who advance to larger helicopters.


Safety ... Student Margins And Crashworthiness
Schweizer Aircraft is a world leader in the design and production of training aircraft,including sailplanes used by most soaring schools in the United States, fixed wing trainers used by the U.S. Air Force Academy, and the Model 269 Series helicopters, which perform commercial and military training roles in over 65 countries.

Safety does not happen by chance. It is engineered into the design of each aircraft that Schweizer produces. It is Schweizer Aircraft's firm belief that there are two imperatives for training aircraft: a) they must provide adequate student margins so that the possibility of having an accident is minimized, and b) they must have crashworthiness characteristics such that in the event of an accident, the possibility of injury or death is minimized.

For flight training aircraft, student margins are a major consideration. Student margins refer to the performance and control response available for a student pilot to make a mistake and still have sufficient reserves for the student or instructor to recover the helicopter. With the 300CB's large power reserve, the kinetic energy available in its rotor system, and an engine overspeed range greater than the normal operating range, the 300CB exhibits safety margins that are equal to or better than those of any other piston-powered helicopter.

Crashworthiness and pilot safety are paramount. The 300CB retains the same tri-level energy absorption system used in the 300C. In the event of a vertical impact, twenty-three inches of stroke is achieved through compression and yielding of the landing gear, crushable sub-floor, and seat structure. This energy absorption, one of the primary secrets of the 300C's excellent safety record, has been retained in the design of the300CB.


Maintainability Made Simple
The Model 300CB has been carefully engineered to minimize downtime and direct operating costs; it is 100% maintainable in the field. The only maintenance required between 100 hour inspections is rotor system lubrications every 25 hours and oil changes every 50 hours. Each 100 hour general inspection requires the same simple checks and maintenance is performed at 600 hour intervals. The 300CB is totally field maintainable and does not require return to the factory.

To help reduce direct operating costs and downtime, component lives are 4,000 hours and above for the main rotor. All other major component life limits exceed 4,200 hours. The Lycoming engine has an ample overspeed margin to reduce the riskof expensive engine teardowns.


Value You Can Count On
Schweizer Aircraft believes the 300CB is the finest commercial training helicopter available in the world today. The combination of training effectiveness, safety, logistics support, performance and operating flexibility sets the 300CB apart from the competition. Like the 300C, the 300CB will hold a high residual value.
