Enaer Namcu / Eaglet
Euro-Enaer EE-10 Eaglet
The ECH-02 Ñamcu light aircraft project started in June 1986 and assigned to the Department of Research and Development Company. The idea behind the project was to develop new design capabilities and gain experience with composites, hoping to eventually offer the local market a civil lightweight and relatively inexpensive, aerobatic trainer. The engineering used computer-aided design (CAD) and while US would provide the raw material, the design of structures and systems would be Chilean.
The construction of the first prototype was started by ENAER in February 1987, receiving the civil registration CC-PZI on 31 March 1989.
Its first flight occurred on 8 May 1989, being taken to the Le Bourget airfare in June and officially shown in Chile on October 6, all in the same year. Its construction number was 001 and factory number ECH-002.
The situation of CC-PZI remained unchanged until May 14, 1996, when the civil registration was canceled as being sold to the Chilean Air Force. With the FACh , starting in June 1996 and assuming the number 181, it was based at the Group's facilities 11 in Los Cerrillos.
From 2000, the aircraft became 181 renamed Eaglet (instead of Ñamcu), since ENAER wanted to occupy it as a flight demonstrator. At the FIDAE 2000 this aircraft was displayed as "181 Eaglet".
To become Eaglet, the original Ñamcu 181 gradually received a number of changes to its engine and propeller, interior accommodation, undercarriage and wheels, flaps and avionics. The EE-10 Eaglet version being developed jointly by ENAER and Dutch partners. On July 3, 2001 this unit abandoned the military number and was reregistered CC-PZC to ENAER. This aircraft was later displayed at the National Museum of Air and Space.
The second prototype cn 002 of Ñamcu was finished in 1990, the registration CC-PZJ assigned the April 9 of that year.
CC-PZJ in Europe
After being presented at the Farnborough Airshow '90, from England made a private demonstration (Chilean pilot and one European) in which they experienced flutter, managing to land shortly before the entire rear section broke. It happened after 150 flight hours. The remains were then used extensively for structural investigation and its cabin was used to mock-up in the doomed EuroEnaer EE-10 project in the second half of 90s, and also for research and testing of destructive dynamics of shock and collisions, best configuration of seats, effects fairings, etc.
The third Ñamcu prototype was also manufactured by ENAER. Its registration was CC-PZK (cn 003), assigned on 28 October 1991. This aircraft served as a basis for studying the possibility of certifying the type in Chile and FAR 23 utility category and the idea of promoting it to the IAF as determiner flying skills (this unit received some modifications requested by that air force).
On February 11, 1992, the aircraf crashed on at the farm of San Damiano, near We. Squadron commander Saa Francisco Izquierdo was killed. This accident ended projects associated with ECH-002, closing the Ñamcu office in Santiago and temporarily finish the program. The registration was canceled on April 2, 1993.
Shortly after the accident that destroyed CC-PZK, began the fourth prototype, for the ÑAMCU kit and the road to the Euroenaer EE-10 Eaglet. The kit project had the idea of targeting the US market, being certified in that country. The subsequent project was called Kit Ñamcu. The idea was for a cheaper and more aerodynamic design, simpler construction and a better price.
In early 1993 the construction of the fourth plane, registered CC-PZL(cn 004) on March 26 of that year, ended th ENAER name. It was displayed at the Sun & Fun in Florida that year, then went back to the workshop, returning to fly in October 1993.
Then a pair of Chilean companies were subcontracted to build a number of pieces of composite and metallic materials, but the final product was not good nor timely. After that, the aircrat went to the US together with a kit, and was being touted in Florida by pilot Harry Hayman.
In 1994 Dutchman Jan Van Toorn, a former aeronautical merchant house linked to Piper, was contacted, who offered to send the kit to Holland, and market it. In 1996 a group of Dutch executives arrive in Chile to begin the certification process for their country. The joint idea between ENAER and Dutch executives was to establish an independent company in the Netherlands that could take the call Project Eaglet. In February 1997 Chilean executives traveling to Holland with technical documentation of the Ñamcu Project; soon after, the joint-venture Euroenaer was founded.
While that was happening, in June 1996 the CC-PZL passed to the FACh as 182 and was based with Group 11 with the 181 (ex CC-PZI). The registration CC-PZL was canceled on 31 May 1996. Soon this aircraft would lead role in the birth of EE-10 Eaglet. In February 1998, the CC-PZL / 182 aircraft would be packed to Holland, where it received a number of improvements in order to participate in the start of the Chilean-Dutch joint venture.
Some of these improvements were:
A more powerful O-320-D2A engine [145 shp / 2,450 RPM and 160 shp / 2,700 RPM for 5 minutes] was fitted replacing the 115 hp Textron Lycoming O-235-N2C;
The cabin was re-design ergonomically and expanded;
The flaps and rudder were redesigned;
A new propeller, flaps, Trim, smaller systems in door locks and hood were fitted.
The CC- PZL / 182 and then became the first Eaglet (or semi Eaglet) to support certification as utility JAR 23 category (for private aircraft under 5,670 kg / 12,500 lbs [and enabled maneuvers such as lazy 8, Chandelas, steep turn, etc.].
In Holland the CC-PZL / 182 (004) was registered as PH-EAG under the Euro-Enaer Eaglet EE-10 designation, in April 1998, and on behalf of Euro-Enaer Holding BV, Den Helder.
Finally, when EuroEnaer collapsed in February 2000, the University of Delft had the aircraft, and registered to the University in July 2002. Under this new status was used as a basis for the development of other projects, including the installation of a fly-by-wire system in the basic flight controls. This project was soon canceled, although the aircraft continued in the Netherlands.
After the progress made with the CC-PZL / 182 modified during 1998 in Chile, began the manufacture of the first Eaglet itself, cn 005. This was done following the European specifications. In Chile the complete structure corresponded to the EuroEnaer assembly in Holland and installation of the cabin and seats. Construction of 005 in Chile was practically in real time with arrival of information from Holland.
Once completed, the fifth aircraft went to Holland in 2000. Flight tests were made on it to complete the certifications uncompleted with the modified CC-PZL. It incorporated the modifications already made in the CC-PZL and CC-PZK, as more powerful engine, new propeller, and a new cockpit design provided by TU Delft. In Europe it was registered as Euro-Enaer EE-10 Eaglet PH-ABG (cn 005) in November 2000 and on behalf of Euro-Enaer Holding BV in Den Helder. The Eaglet design was certified JAR 23 type on July 13, 2001.
cn 005 in Europe
Linking EuroEnaer with RLD (Rijksluchtvaartdienst, the Dutch DGAC) determined that the company was in charge of the final assembly and certification, in addition to providing engines, accessories, paint and interior. Meanwhile, ENAER deliver all the airframe.

The final certification of design and manufacturing rights were took longer than desired, and during this delay EuroEnaer began with financial difficulties that made it go bankrupt. Additionally, the participating contractor, Renegade Aircraft CV, in 2001 provided additional problems to the project by claiming the protection of their rights related to the Eaglet and threatened with lawsuits.
Finally, EuroEnaer bankruptcy in February 2002 suspended certification of design and with it the value of the aircraft type certificate. Then ENAER bought what remained of the joint venture and planned to validate alternative type certification in the Netherlands.
In August 2002, the only Eaglet built , cn 005, was returned to the plant in El Bosque. Once in Chile, on November 27, 2002 was registered CC-PBZ as EuroEnaer EE-10 (cn 005), and the title of ownership to ENAER was formally a sale to EUROENAER Holding BV under contract formalized in Santiago November 18 2002.
During FIDAE 2000 an unfinished airframe with leftover pieces, enabled presentation was the fantasy CC-OO7 makings.
Finally, the project was forgotten as it was clear that with the large number of similar aircraft on the international market, the future, if there was any, was very complicated.
If the Eaglet still flies, it does with an Experimental Certificate, restricted only to marketing operations, testing and restricted flights, but no instruction or for profit with it.
