Thai Lakota

In 2014, the Royal Thai Army acquired six UH-72A Lakota helicopters from Airbus Group through the US’s foreign military sales programme. After receiving training and in-country support, the Lakotas’ first two years in operation have gone smoothly, an example of hard work and dedicated personnel.

The Royal Thai Army (RTA) is Thailand’s largest military branch. In addition to conventional military undertakings, its airborne arm is responsible for Emergency Medical Services (EMS), evacuation, reconnaissance and utility services. Its rotorcraft fleet comprises a variety of makes, many of which – as in the case of its Vietnam-era Huey helicopters – are in need of replacement.

To this end, the RTA acquired six new Lakota helicopters from Airbus’ North American division, Airbus Helicopters, Inc., in 2014. For the army’s pilots, like Captain Pongsaton, the commander of the RTA who has experience on the older helicopters, the new aircraft offer a distinct advantage. «The Lakota is very easy to fly. We mainly fly utility, transporting equipment to the mountains or jungle, and we need to take off in confined areas. The Lakota’s instruments and autopilot systems help us avoid obstacles».

The RTA’s purchase of the Lakotas came with a unique support set-up: five weeks of training for pilots and maintenance personnel at the division’s headquarters in Grand Prairie, Texas, followed by support in the form of one field service and one logistics representative in Thailand.

«The RTA saw that in-country support was needed because it was the first time they had acquired this type of helicopter», says Chong Eu Chuah, the contractor field service representative (CFSR) from Airbus. «My role is part of Airbus’ support guarantee to ensure a smooth entry into service for the Lakotas in Thailand».

Originally a technician at Airbus Singapore, Chuah trained for a month in Texas along with Chong Siew Fwai, the Contractor Logistics Service Rep (CLSR). They joined a group of six RTA pilots and ten technicians who would complete theory and simulator instruction, as well as flight training on the UH-72A. In all, 18 pilots and 30 technicians trained through the programme. «We got to know our future colleagues well, as well as setting up lines of communication», says Chuah. «By the time the aircraft arrived in-country we were ready to assume our duties».

In Thailand, Chuah’s responsibilities vary from troubleshooting and on-the-job training, to supporting maintenance or supplying technical assistance at one of the RTA’s five bases – Phitsanulok, Lopburi, Roi Et, Bangkok, and Nakkon Si Thammarat. «For troubleshooting, I normally drive to the sites», he says. «If it is too far (Nakhon Si Thammarat is 900 km/559 miles from Lopburi), I travel by commercial airlines. It is a tiring job but we show commitment to our customer».

Speaking for the RTA’s technical staff, one mechanic offered the comment, «The RTA’s missions cannot be carried out if we don’t have perfect maintenance and a great contribution from the US Army and Airbus Helicopters in sending someone who is an expert».

On the logistics side, Chong Siew Fwai set up a warehouse and inventory of Lakota spares, equipment and tools. Based in Bangkok, he handles purchase orders, equipment loans, parts shipments, and consults on nearly all logistics issues that come up with the new Lakotas.

The entry into service was not without a snag. «During the initial entry into service, we faced some avionics problems, possibly due to humidity during the sea journey from the USA coupled with the rainy season in Thailand», says Chuah. However, with time, his help has shifted from problem-solving to supplying hand’s on – or even remote – training. «As the mechanics gain more experience, I do not travel to the sites as often. I can provide instructions, drawings, photos and video through smartphone».

During their two years in operation, the RTA’s Lakotas have seen an availability rate of 100% when the aircraft are not scheduled for maintenance. «We selected the Lakota for use as a utility helicopter», says one pilot, speaking on behalf of his colleagues. «We like the UH-72A because it is large, comfortable and easy to fly. It’s almost too powerful when hovering into a nose wind and very stable with low vibration».

Behind the Lakotas’ success is a team of dedicated people. «Chong Siew Fwai and I stayed on in Grand Prairie after the type course training to meet key personnel at Airbus in the technical support and logistics departments», says Chuah. «It is easier to help someone you know than a total stranger. I believe these are the reasons for the Lakotas’ smooth entry into service».

Cost-effective solution

The United States Army has exercised $65.8 million in contract options for 12 additional UH-72A Lakota helicopters and associated mission equipment packages. The UH-72A is manufactured by Airbus Helicopters Inc. at its final assembly plant in Columbus, Miss., which has already produced and delivered almost 350 Lakotas to date, all on time and on cost.

The UH-72A was competitively selected in 2006 for a broad range of active Army and Army National Guard missions, including training, search and rescue, medical evacuation, border security, command and control, VIP transport and general utility.

The 12 aircraft on this latest contract option will be delivered starting in August of 2017, configured for the Army as initial entry rotary-wing trainers. This year the Army has fielded more than 50 Lakotas to Fort Rucker, Alabama, in preparation for the UH-72A’s formal introduction into the training curriculum by early 2016. Ultimately, Army plans call for an initial-entry rotary wing training fleet of 187 Lakotas, made up of a mix of new deliveries and already in-service aircraft reconfigured for the training mission.

«Time and again the UH-72A has proven to be the most cost-effective solution to meet a wide variety of needs for the U.S. military and our allies», said Allan McArtor, Airbus Group Inc. Chairman and CEO. «The Army’s flawless execution of the Lakota program has proven that even in today’s challenging defense acquisition environment, there are success stories for the taxpayer and warfighter alike».

«Almost half the men and women who build the UH-72A in Mississippi are U.S. military veterans, and some even fly in Lakotas in the National Guard or Reserves», said Chris Emerson, President and CEO of Airbus Helicopters Inc. «Everyone on that production line takes a great amount of pride in their unbroken record of delivering on their commitments, and we hope they’ll be building Lakotas for many years to come».

The Lakota continues to meet a wide range of needs for several military user communities. The Navy operates the Lakota in a training role at the U.S. Naval Test Pilot School and the Army National Guard units operating specially equipped Lakotas are deployed supporting Customs and Border Protection missions along the U.S. southwest border. The Royal Thai Army is the first allied operator of the UH-72A, having purchased six aircraft to date through the U.S. government’s Foreign Military Sales program.

A modern, twin-engine helicopter, the UH-72A is a powerful, stable, and agile platform with a glass cockpit that is compatible with night vision goggles. The Lakota is also single-pilot Instrument Flight Rules certified. It has the lowest cost to buy, own and operate of any U.S. military helicopter in production.

The aircraft will join seven Lakotas previously in the Army inventory that have already been modified to the training configuration and fielded to Fort Rucker, in preparation for the Lakota’s formal introduction into the training curriculum in early fiscal 2016. Ultimately, Army plans call for an initial-entry rotary wing training fleet of 187 Lakotas, made up of a mix of new deliveries and already in-service aircraft reconfigured for the training mission.

To date, the Department of Defense has ordered 411 Lakotas, 400 helicopters for the U.S. Army. With today’s delivery, 332 completed aircraft have been delivered – all on time and on budget – from the Airbus Helicopters Inc. production facility in Columbus, Mississippi.

«For a program to succeed in the current budget environment, affordability and reliable program performance must accompany mission flexibility», said Allan McArtor, Airbus Group Chairman and CEO. «Since awarding the contract in 2006, the Army has managed this program unfailingly on cost and on schedule, and we’re proud to see that record continue as we deliver the latest configuration of this versatile, multi-mission aircraft».

«We’re making the necessary important investments to ensure a successful transition of the Lakota into training operations at Fort Rucker», said Marc Paganini, President and CEO of Airbus Helicopters Inc. «We’re honored that future Army aviators will begin their flying careers at the controls of the Lakota».

The Lakota was competitively selected in 2006 to fill a wide variety of roles for the Active Army and Army National Guard, including search and rescue, medical evacuation, border security, command and control, VIP transport, general utility and training. Army National Guard units, operating UH-72As equipped with the Security & Support Mission Equipment Package, are deployed supporting Customs and Border Protection missions along the U.S.-Mexico border. The Lakota is also operated in a training role by the U.S. Naval Test Pilot School.

The Royal Thai Army has ordered UH-72As through the U.S. government’s Foreign Military Sales program. These Lakotas are scheduled to be fielded to Thailand within the coming months. Airbus Helicopters is marketing the UH-72A to other allied nations with requirements for a modern, low cost multi-mission helicopter.

A modern, twin-engine aircraft, the UH-72A is a powerful, stable, and agile platform with a glass cockpit that is compatible with night vision goggles. The Lakota is single-pilot Instrument Flight Rules certified. It has the lowest cost to buy, own and operate of any U.S. military helicopter in production, and is built in Columbus, Mississippi, by a workforce that is 43 percent U.S. military veterans.

The Eurocopter EC145 is at the top of its class in the medium-sized. The EC145 is equipped with two Turbomeca Arriel 1E2 engines that deliver outstanding performance and vital power reserves – even in One-Engine-Inoperative (OEI) scenarios. Its reliability is further enhanced by a completely separate fuel system, a tandem hydraulic system, a dual electrical system and redundant lubrication for the main transmission. It is certified for single pilot Visual Flight Rules (VFR) day and night operation.
