Quick Summary
The National Oceanic and Atmospheric Administration (NOAA) intends to award a sole source purchase order to GMS International Corporation (Reston, VA) for two Rosemount 858AJ115 Heated Air Data Probes for its G550 aircraft. This presolicitation notice is not a request for competitive proposals. Firms believing they can fully meet the government's requirements may submit substantiating documentation within 15 days of publication to challenge the sole source determination.
Purpose & Scope
These probes are mission-critical components for NOAA's new Gulfstream G550 Atmospheric Research Aircraft, enabling the measurement of three-dimensional wind vectors and "truth" pressure data. This acquisition is vital for NOAA's mission of high-altitude tropical cyclone surveillance and environmental sampling. The Rosemount 858AJ115 features a unique five-port hemispherical head geometry essential for calculating 3D wind vectors in turbulent environments. Standard "brand name or equal" pitot-static tubes are unsuitable due to inability to maintain calibration or structural integrity at high flow angles encountered during hurricane reconnaissance.
Technical Justification
The required probes must be fully compatible (form, fit, and function) with the existing G550 nose boom instrumentation system, which was specifically engineered for the Rosemount 858AJ series' unique bolt pattern and pneumatic port spacing. The aircraft's specialized de-icing power bus is configured for the 115V AC internal heater elements of this exact model. Other products would require extensive and cost-prohibitive airframe re-engineering and recertification. GMS International Corporation is identified as the sole worldwide distributor (except Japan) and the only vendor capable of providing this specialized hardware with necessary FAA Airworthiness Documentation (Form 8130-3).
