Helio Aircraft Corporation
Founded in 1948 by Drs Otto C. Koppen (professor of aeronautics at MIT) and Lynn Bollinger (professor of management at Harvard) this company was created with the intention of developing an aircraft with STOL capabilities close to that of a helicopter. His research and testing resulted in the famous 1952 Helio Courier model (derived from Helioplane 1949) - an aircraft capable of flying at speeds well controlled ultra-low and take off or land on unprepared stretches of only 100 feet long.
It was used for military and intelligence in Southeast Asia with great success late, taking an immediate operations "bush flying" in various parts of the world acceptance. Twin versions were developed, artillery and rocket-assisted takeoff and other types contributing to the reputation that has this legendary aircraft.
For 1974 Helio was acquired by General Aircraft Corporation, paradoxically company sued the CIA for alleged unlicensed production of the device in Portugal, leading to an abrupt end the company's relationship with the government. After changing hands several times over the rights Courier and Stallion model were acquired by Helio Aircraft LLC of Arizona, who announced summarize production in 2004, with no new release to date (2013).

Helio Aircraft Bolivianos
The first Helio Courier registered in our country was imported by the Summer Institute of Linguistics , which we have already spoken on other pages as unavoidable reference for general aviation pioneer, in fact this entity imported a second aircraft type H-391B in 1957 operating with both units until 1973, when it reformed its operations in Bolivia and religious tinge began to focus almost exclusively on activities anthropological.
Another religious entity that operated an aircraft of this type was the Adventist Mission Seventh Day , which featured a H-391 operating in Bolivia between 1958 and 1966, we believe this was sent to Peru after his service in the country as this Church had its air base in Pucallpa Puno and then. Adventist mission settled in Lower Peru since 1911 had been founded by Pastor Ferdinand Stahl and his wife Christina Carlson who then retreated to Iquitos. Among other means, employing different Helio Aircraft, Piper and Cessna as mobile clinics as transport and logistic support to their camps, one of the H-391 was named for Stahl in 1963.
Out of evangelical missionaries, the first organizations that took advantage of the benefits of these aircraft were different mining companies and oil industry, these include the South American Placers , which in 1958 had gold mining operations in the north of La Paz. The company ESTALSA a distressed unit H-295 in Potosí in 1971 and the Unified Empresa Minera SA , through its subsidiary Auro Taxi Ltda .
The latter used two HST-550 Stallion units as a means of linking mines EMUSA in San Vicente (Potosí), Kori Chaca, Kori Kollo (Oruro), Holy Spirit and antimony mines and Caracoto Chilcobija north of Tupiza. One of these aircraft, the CP-1396 stands out for having a fascinating operational history in Cambodia, Alaska, Bolivia and then back in the U.S. where it is nigh disappeared after having survived the flooding caused by Hurricane Katrina .
Similarly, in the east of the country operated for some years the CP-655 ship owned by Petroleum Helicopters (of Bolivia) SA , the company based in Lafayette - Louisiana, highlighted the country an exclusive group of aviators mount the mid-50 YPFB as subcontracted operators, among them was the Cap. Lynn Clough, recognized authority on air services to the offshore oil industry. His job was to transport supplies and personnel, geologists, surveyors and other technical-a different camps in an arc from the exploration to the Beni Chaco, bordering the Chapare. Aside from this company Helio Courier aircraft used Havilland Beaver and Otter and also operated a helicopter Aerocommanders SA315B Lama.
Among the latter was independent operators Callaú Jose Justiniano , who began his Air Taxi company in Santa Cruz with a H-391B Callaú purchased in Colombia and came to operate seven Cessnas (three former Paraguayan) until the late 70s.
Apart from all these operators, stands with no fewer than six units H-700 and H-800 manufactured eighteen, Cochabamba company SRL Andean Wings , owned by Ernesto Asbún. Andean Wings is known for having some very interesting models imported into the country is to test and offer to the public as well as initiate the specialized companies such as Aero Jets , practically the only (up to 2013) national executive aviation company equipped with reactors. Regarding your Helios, apparently placed three ships managed with private operators, one failed to be imported only three came to the country to be immediately returned to the United States, allegedly by the suspension of credit for import.
Of these ships, the last to operate in our territory have been the CP-1900, a H-700 imported in 1984 came to "current" in the aviation record 1992 as the property of Raúl Velasco Suárez , we understand was returned to USA end 1993, although no official FAA records of this transfer.

Twin Helio U-5A civilian colors and USAF to early 60s.
Other Helio aircraft operating in Bolivia
Among the motley crew of aircraft and prototypes that have come to "test engine" on the heights of the administrative capital of Bolivia not missed a rare specimen as was the twin-engine Helio H-395.
Air America Operations
In the summer of 1965 a ship U-5A piloted by Cap. William R. Andresevic contractor Air America came to Bolivia to "assessment by the U.S. Embassy and atmospheric type tests" , this aircraft would be one of two existing at the time: the USAF 59-5955 C / N 01 (more likely) or 59-5956 C / N 02 was treated no less than one of the two prototypes built with funding from the CIA for covert operations in high altitude areas.
These engined ships had been built thinking of access points in the rugged Himalayas in order to intercept telegraph wires and remote monitoring instrumentation placed facing China, such as the famous case of an instrument telemetry powered nuclear batteries lost the snowcapped Nanda Devi. (Source ) T  lso used the ship p ara introduce counterintelligence staff in Mongolia or in the newly communist China occupied Tibet. In fact the first device was eventually registered in India as VT-DVE, and presumably would have been spent on these activities, then a dozen U-5B models were built and all operations would have been destroyed except for one. Also there are some fuselages of "civilian version" (pressurized with retractable gear), which came to no end.
The aircraft returned to the U.S. after some time in Bolivia, receiving a mixed assessment as to their capacity, but positive in terms of stability and maneuverability. How could it be otherwise Gen. René Barrientos, who was then 46 years old and then co-president, personally piloted the ship for 30 minutes on July 2, 1965 in a test flight "to joining the Bolivian Air Force " . This experience became a propaganda article reported in the bimonthly edition of TIME magazine, no doubt in an effort to obfuscate the real purpose of the visit to Bolivia.
USAF Operations
As background to this operation had been in the country have a U-10 piloted by Col. Robert Gleason, this ship came via Panama Peru and Chile, La Paz by entering "unknown" mountain pass just to injury when landing on El Alto, crashing against a rocky promontory and destroying its landing gear.
Another ship arrived as a replacement on a C-130, this came equipped with cameras that help map the vegetation of the Alto Beni and San Joaquin, in an attempt to combat the disease haemorrhagic fever endemic to Bolivia elevated to the rank of bioweapon thanks investigations of PHS. In this context, Helio U-10 were used for transportation and logistics for aerial photography, identifying areas of low vegetation inhabited transmitters rodent Black FHB or typhus, and then destroy them by aerial spraying.
Conservation International Operations
While these are two cases where important military operations type are identified, we also identify a case where environmentalists laudable objectives were achieved, with irreplaceable support of air assets.
Between 1990-92 operated in the country have a Helio H-800 of unknown origin (possibly one of the ex-Andean Wings warehouses around the country on a temporary lease) was assisting the work of the RAP biological research organization Conservation International . This expedition worked in the Pampas of Heath, Madidi and Gran Chaco generating important discoveries in the field of South American biology, as basis of the findings presented a report which led to former President Gonzalo Sánchez de Lozada to testify the Madidi National Park in 1995, extending this biosphere reserve 1.8 million hectares and protecting the future for one of the wonders of Bolivia's biodiversity.
