Can we manufacture the spare parts? I mean do we have companies in this country that can fabricate spares for the Huey?

BELL HUEY II


Huey II Modernization Program Extends And Enhances Life Of A Proven Performer

If you need unparalleled, increased performance from your Huey fleet, look to the Bell Huey II. This factory-certified upgrade package boasts 28% more takeoff power and an increase in payload of over 291 kg (642 lbs). Designed to deliver, regardless of altitude or temperature, the UH-1H with the Huey II kit installed can provide an incredible 275% increase in hover ceilings at 4,308 kg (9,500 lbs.) on a hot day. This comes with an improved maintenance schedule and dramatically reduced operating costs. As testimony to its reputation as a workhorse, the Huey is used by more military forces in more countries than any other helicopter.

The UH-IH helicopter has served the United States military for more than 20 years, setting the performance standards for all helicopters. Since the start of production, over 10,000 of these flying workhorses have been built. Today, over 5,000 of these reliable, dependable Bell products are still flying in over 45 countries around the world.

Unlike many risky modernization programs, the Huey II is a helicopter based upon proven design and utilizes the durable existing UH-1H airframe and production parts from current programs still in production. Every part for the Huey II is in production today, which reduces your risk and guarantees a ready parts supply to assure many more years of continuous service and an infinite useful life span as components are overhauled or exchanged at retirement.

The Huey II's increased performance is achieved through an upgraded Lycoming engine, which is the same engine that powers the AH- IS Cobra. The increased power generated by the Lycoming T53-703 engine feeds the dynamic components taken from the powerful Bell 212. This is the kind of power which yields a 39% increase in hover on a standard day and over 275% increase in hover capability on an extremely hot day at the high temperatures found in real world environments.

The Huey II is a modernized aircraft, made popular by its renowned dependability and proven performance. It will now fly more payload than its predecessor the UH-1H, and all at a significantly reduced cost of operations. Most importantly, the Huey II is backed by the world's leader in helicopter manufacture...Bell Helicopter Textron Inc.


Operational Benefits-Increased Performance:

* Increased Payload
* Increased IGE Hover Capability
* Increased OGE Hover Capability
* Increased Payload for Same Range


Modernization Program You Can Perform On Your Own Existing Aircraft


Posted Image


Most operators who currently fly the UH-IH can perform the modernization in their own facilities. The Huey II modernization is essentially an assemblage of upgraded components which are incorporated into your existing UH-1H airframe. In about 12 weeks, the aircraft can be dismantled, the transmission and the engine rebuilt, the new parts installed, and the Huey II emerges ready to take its place in the operational fleet. Or, if it better suits your needs, the modernization can be accomplished in the United States by a highly qualified Bell authorized facility.


If You Fly The UH-1 H Or UH-1 D Now, You Can Modernize And Maintain The Huey Il.

Only one simple special production tool is required to accomplish the modernization, and the purchase of other tools needed to maintain the helicopter is minimal. The program can be designed around your needs and experience. Bell Helicopter offers technical assistance if you need it, when you need it, and where you need it. We have built the aircraft as you will build it. Our plans for you will be correct and simple to follow.


The TEXTRON Lycoming Powerplant


Posted Image


At the heart of the Huey II modernization program is an upgraded version of the familiar Textron Lycoming T53-L- 13B turboshaft powerplant. Since its introduction, the T53 turboshaft has come to represent reliable and outstanding hot day/high altitude performance as well as effective modular technology for military and commercial applications throughout the world.

The T53 was the first turbine ever designed specifically for helicopter applications; consequently it affords ease of maintenance and assembly interchangeability with a negligible change in SFC's. These features enable the T53 engine to be upgraded in the Huey II to provide an increase of 400 SHP, 28% more takeoff power, and handle 642 lbs/291 kg more payload with essentially the same fuel consumption as the current UH- IH.


Mission Performance

By incorporating the desirable efficiencies and components of existing successful aircraft, the Huey II advances as a performance leader for multi-mission capable transport helicopters. The Huey II modernization re-suits in a significantly more effective helicopter with enhanced flight and performance features.


Hover In Ground Effect (Takeoff)

The improved power capacity of the Huey II modernization increases the IGE hover ceiling 39% on a standard day at 9,500 lbs/4,308 kg. Real performance benefits are realized on a hot day (ISA + 20° C), when a Huey II achieves a 275% increase over the UH-iH in hover ceiling at 9,500 lbs/4,308 kg gross weight.


The Cost Efficient Solution


Posted Image


The improved reliability and maintainability of the Huey II has resulted in a heli­copter that requires significantly less maintenance touch time than that for the UH-1H. This produces a substantial savings, as shown below, and vast­ly improves operational ready rates for the field commanders.

Overhaul requirements for Huey II major components have been greatly reduced from the UH-1H by using commercial Model 205/212 parts. This greatly reduces maintenance requirements and overall life cycle costs.


Posted Image


Based on a flying hour program of thirty hours per month, the Huey II program, including engine upgrade, pays for itself in less than ten years. With a 40-hour per month flying program, the payback period is reduced to less than seven and one-half years. The Huey II continues to save you money throughout the life of the helicopter.


The Sensible Solution To Continued Effective Helicopter Operation

The Huey II modernization is the logical and sensible solution for current and prospective operators to maximize the excellent features of the existing UH-1H.

This cost effective upgrade program will result in an aircraft that is more reliable, more efficient and more effective in a wider range of environments. The Huey II already has a proven service history, lower maintenance costs and the backing and support of the world's leading helicopter manufacturer... Bell Helicopter Textron Inc.

It seems funds are not yet ready. PAF has a lot of HUEY waiting to be converted into HUEY ll.
Maybe not all operational HUEY of PAF are candidate for HUEY ll program and only those with latest batch of date manufactured can be considered.. I hope some professionals here can shed a light.

Much I would like for PAF to have a new type of Modern combat Helicopter, but the present Low class condition of our economy dictate that a proven existing upgrade program with reasonable cost is more realistic for PAF New Helicopter.

Manokski reports that funds for 10 Huey II conversions were re-allocated for the acquisition of additional UH-1Hs.

The PAF had an immediate need for additional helicopters. Quantity won out over individual quality.

Nice revelation that PAF has taken the direction of HUEY ll program.:specool:

Much better if all HUEY (UH-1H) in PAF inventory will be subjected to HUEY ll modernization program. That is our best alternative than buying new ones not knowing if our economy is going to be stable after six years or more.

With HUEY ll, PAF can operate and fully maintain its fleet of upgraded helicopter without affecting its budget.

It would look like we have a new Helicopter if the present inventory of PAF HUEYs (UH-1H) are all converted to HUEY ll.

I'm sorry to break it to you Sir Erwin but what Adroth is to trying say is that the money meant for the upgrade 10 of our Hueys to Huey II standard will be used instead to buy additional 2nd-hand UH1H Hueys

It seems the PAF would rather delegate our few Huey IIs to where their enhanced capabilities are better appreciated namely for SAR or possibly for SpecOps ise.

They still insist on using refurbished UH1Hs in the troop/load mobility role as they are still seen to be the most cost-effective troop/cargo carrying option at the moment despite the PAF Huey fleet's recent accident record.

The logic at work here is that it could be impractical to upgrade large numbers of Huey IIs when the stock UH1Hs can still do their job as is. It would also be more practical to buy more Hueys to meet mobility needs when you can only upgrade a few for that same price.

Furthermore, with plans to buy newer utility helos in the works, there is no need to upgrade large numbers of hueys when newer types will be purchased in a few years.

The immediate need to fill the AFP's mobility gap in its long running COIN campaign seems to also be a greater priority. It would take longer to upgrade Hueys than to ship, test and refurbish used ones when the Palace wants our insurgency headaches to be over by 2010.
