The German Aerospace Center, acting for its flight experiments facility intends to award a frame agreement for maintenance services relating to the research aircraft HALO (here: Gulfstream G550 /D-ADLR) over a period of 4 years. The general tasks of the maintenance services are based on Gulfstream's ‘Maintenance Due Lists’ (Example: See under Attachment 1 of the attached PDF-File) based on following data:

— Aircraft make: Gulfstream,

— Aircraft model: G550- Regulation: DEU-GCAA,

— Engines: 2x Rolls Royce BR700-710 C4-11 (G550) -> Serial No 15284, 15285,

— Aircraft Serial No 5093,

— Airworthiness date: 7.11.2005,

— APU: Honeywell RE220 (G550).

The aircraft HALO (High Altitude Long Range Research Aircraft) did herald a new chapter in the history of German atmospheric research and earth observation. HALO is based on a Gulfstream G550 ultra-long range business jet. The combination of range, cruising altitude, payload and comprehensive instrumentation makes the aircraft to a globally unique research platform. In almost all important parameters, HALO exceeds the performance of research aircraft operating worldwide as follows: With a cruising altitude of more than 15 kilometers, a payload of up to 3 tons and a range of more than 12 000 kilometers, for the first time measurements can be carried out on a continental scale, at all latitudes, from the tropics to the poles, and at altitudes as high as the lower stratosphere. As a result, it is possible to answer scientific questions relating to areas that where inaccessible to previous research aircrafts operated by the German Aerospace Center. HALO was delivered on 21.1.2009 and landed at the location in Oberpfaffenhofen after a non-stop transatlantic flight from Savannah, USA.

The bidding procedure will be carried out as a negotiated procedure with a call to participate according to Section 17 VgV.
