IntroductionThe Bell Huey II is the ideal platform for the customer that needs heavy lift capability at an affordable price. Using the rugged and proven UH-1H airframe, the aircraft is upgraded with modernized components, giving the aircraft new life as a more robust and capable medium utility helicopter.
Unsurpassed as a law enforcement utility helicopter, the Bell Huey II carries up to 11 fully outfitted SWAT team members, without the need for external platforms, delivering excellent lift capability with single-engine economics. Emergency response teams also appreciate the exceptional cabin volume and ample power of the Bell Huey II, facilitating a wide range of search and rescue, disaster response, special operations and fire fighting missions.
The Bell Huey II is a versatile multirole medium lift aircraft that offers maximum performance at an affordable price. Starting with the venerable UH-1H airframe, the aircraft is upgraded with modern commercial accessories and all components are refurbished or replaced to zero-time condition.
This major upgrade greatly improves performance, decreases direct operating cost and extends the life of your Bell Huey II. Hover ceiling increases 39 percent on a standard day, 275 percent on a hot day. Payload increases to a maximum internal gross weight of 10,500 lb (4,763 kg) and 11,200 lb (5,080 kg) external gross weight. Direct operating cost is lowered by nearly 30 percent. Best of all, it’s the only UH-1H upgrade designed and backed by Bell Helicopter, so conversion is easy and reliability is assured. With over 300,000 flight hours amassed across a fielded fleet of over 225 Bell Huey IIs, it’s also proven to be the smart, cost efficient decision for Huey owners worldwide.
Nothing delivers like a Huey, and the Bell Huey II delivers the biggest return for the smallest investment. It’s a Huey at its best.

The data set forth in this document are general in nature and may vary with conditions. For performance data and operating limitations for any specific flight mission, reference must be made to the approved Flight Manual
Cost of operationsINTRODUCTIONBell Helicopter Textron’s cost of operations data for current production helicopters is based on information from Bell Helicopter operators and service facilities. BHT’s Product Support organization accumulates cost data from a diverse group of operators - large, small; sub-polar, subtropical; inland, coastal; corporate, charter. This information is analyzed to generate sample data for each production model which are averages of the field experience. BHT intends to continue monitoring actual costs to enable annual updates of the data to maintain its currency.
The following discussion is provided to review the variables involved in the helicopter’s direct and indirect cost of operations as well as its cost of ownership.
The total cost of helicopter ownership and operation involves both direct and indirect costs. The direct costs are those which are incurred essentially by the flight hour and include:
• Fuel, Lubricants • Basic Airframe Maintenance • Powerplant Maintenance
The indirect costs are not directly dependent upon the number of hours flown and include: • Insurance • Facilities (hangar, workshop, etc.) • Crew Compensation • Financial Factors (depreciation, investment tax credit, financing costs, etc.)
Sample direct operating cost data is available for each current production model. Detailed estimates for total costs relating to specific operations are available through the BHT regional marketing manager or corporate office using input data supplied by customer/prospect.
DIreCT CosTsFuel, LubricantsA typical average value of fuel and lubricant costs is included in the sample data provided for each model. Fuel consumption depends upon speed, temperature, externally-mounted accessories, sling loads, etc. A band of approximately 10% more or less than sample value will cover these factors for normal operations. Fuel pricing varies considerably based on where the fuel is purchased geographically and whether it is purchased retail or in bulk`. The sample cases use average retail purchase price prevalent at the time of the sample data are prepared.
Basic Airframe MaintenanceAirframe maintenance is divided into four categories:
• Periodic Inspections • Overhauls • Replacement of Retirement Parts • Unscheduled
Periodic inspections include those inspection tasks, with their part requirements, listed in the Maintenance Manual for each model. Man hours for periodic inspections can vary from the sample value provided because of differences in personal experience, tool and parts availability, facilities, environmental effects such as extremes in working temperatures. Man hour costs/hour are also variable among the Authorized Service Centers as a result of differences in local costs, overhead expenses and volume of work. The sample value is an average of costs per hour at Authorized Service Centers at the time of publication.
Overhauls include removal, disassembly, inspection, parts replacement, reassembly and reinstallation of certain components/assemblies at the periods stated in the BHT Maintenance Manual. Overhaul man hour and parts requirements are subject to considerable variation depending upon the helicopter’s operations and environments. The sample data reflect average values.

The data set forth in this document are general in nature and may vary with conditions. For performance data and operating limitations for any specific flight mission, reference must be made to the approved Flight Manual
Cost of Operations (continued)Retirement parts are those which are subject to disposal after an operating time stated in the Maintenance Manual. These are normally components of the rotors/control systems which are subject to oscillatory loads and are designed and tested for use over a finite number of flight hours rather than on their condition. The replacement at the required intervals requires some labor which is included in the man hour data in the sample.
Unscheduled maintenance encompasses labor and parts replacement for major maintenance not covered under the formal Maintenance Manual requirements for inspections and overhauls. It also includes those additional maintenance requirements imposed by the manufacturer through issue of Service Bulletins.
The sample data for periodic inspections provide for some minor unscheduled maintenance tasks resulting from the inspection.
Powerplant MaintenanceThe powerplant (engine [s]) requires periodic inspection and overhauls. The overhaul periods are based on the number of operating hours or on the number of cycles, whichever is the first limit to be attained. Start cycles are a factor because thermal cycles are important in the design of the turbine engine’s rotating components. Overhauls are performed by the engine manufacturer and/or at authorized facilities. Powerplant overhaul can be performed for the engine as a unit, or in some cases for individual modules. (Modules can be gearbox, compressor, turbine, for example.) Each module can have its own overhaul period. Modular overhaul can be cost-effective for some operations and its use should be evaluated. Engine or module exchanges can be made in lieu of overhaul. For details, contact the engine manufacturer or his authorized distributors/service centers. The sample costs are based on an average exchange. The powerplant may also require unscheduled maintenance (unscheduled removals for repair, parts replacement).
INDIreCT CosTsInsuranceInsurance rates are based on a number of factors including claim experience, type of operations, and crew qualifications. Rates can be obtained from insurance agent/broker.
FacilitiesFacilities can include hangar, workshop, parts storage area, tools, ground support equipment and administrative area as appropriate to the specific operation.
Crew CompensationThe number of aircrew personnel depends on the individual operation; i. e., whether the normal crew consists of one or two pilots, hours per day flown, backup requirements for illness, vacation, etc. Bell Helicopter regional marketing managers can advise typical local costs for estimation purposes.
Financial FactorsFunding a helicopter purchase can be accomplished in a variety of ways, including cash, short term note, long term note, partnership, etc. For investment accounting, several depreciation methods also exist; straight line, double declining, sum of the year’s digits, etc. Value of resale is a significant factor.
Miscellaneous FactorsStaff expenses (other than aircrew and direct maintenance personnel), utilities, office expenses, etc.
OWNERSHIP ANALYSIS PROGRAMBell Helicopter Textron uses the most recently published edition of the Life Cycle Cost computer program provided by Conklin & de Decker Associates, Inc. to determine ownership costs for an operators planned period of utilization for the aircraft. Conklin’s Rotorcraft Analysis Office may be contacted at: Phone: (817) 277-6403 or Fax: (817) 277-6402.
Bell Helicopter’s regional marketing managers or corporate office personnel will be able to assist in preparing an ownership analysis which is customized for our customer’s specific individual conditions and needs.
