NOAA's Office of Marine and Aviation Operations (OMAO) Aircraft Operations Center (AOC) is seeking to procure specialized instrumentation for its G550 atmospheric research aircraft. - Government Buyer: - Department of Commerce, National Oceanic and Atmospheric Administration (NOAA) - Acquisition & Grants Office, Eastern Acquisition Division-Norfolk - Office of Marine and Aviation Operations (OMAO), Aircraft Operations Center (AOC) - OEMs and Vendors: - Rosemount Aerospace (OEM) - GMS International Corporation (exclusive worldwide distributor, except Japan) - Products/Services Requested: - Two (2) Rosemount 858AJ115 Heated Air Data Probes - Part Number: 858AJ115 - Description: Heated air data probe for G550 aircraft, essential for high-altitude atmospheric research - Must be compatible with G550 nose boom instrumentation system - Requires FAA airworthiness documentation (Form 8130-3) - Unique or Notable Requirements: - Sole source procurement due to unique geometry, mounting, and electrical interface requirements - Probes are mission-critical for high-altitude tropical cyclone surveillance and environmental sampling - No alternative sources identified; only Rosemount Aerospace products meet the technical requirements - Place of Performance/Delivery: - Delivery to Reston, Virginia, United States - Contracting office located at Eastern Acquisition Division, FED BLDG 200 GRANBY ST SUITE 815, NORFOLK, VA 23510

Description

***THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION’S (NOAA) ACQUISITION & GRANTS OFFICE, EASTERN ACQUISITION DIVISION-NORFOLK, OFFICE OF MARINE AND AVIATION OPERATIONS (OMAO) AIRCRAFT OPERATIONS CENTER (AOC), INTENDS TO NEGOTIATE AND AWARD A PURCHASE ORDER, ON A SOLE SOURCE BASIS, UNDER AUTHORITY OF RFO FAR 6.103-1, WITH GMS INTERNATIONAL CORPORATION OUT OF RESTON, VA FOR TWO (2) ROSEMOUNT 858AJ115 HEATED AIR DATA PROBES FOR G550 AIRCRAFT.

 NO SET ASIDE IS TO BE USED FOR THIS SOLE SOURCE REQUIREMENT. THE ASSOCIATED NAICS CODE IS 334511.

***THE SOLE SOURCE DETERMINATION IS BASED ON NOAA’S REQUIREMENT THAT GMS INTERNATIONAL CORPORATION IS THE SOLE, WORLDWIDE DISTRIBUTOR OF ROSEMOUNT AEROSPACE PRODUCTS EXCEPT IN JAPAN. GMS INTERNATIONAL CORPORATION HAS NO AUTHORIZED PARTNERS OR RESELLERS.

ROSEMOUNT 858AJ115 HEATED AIR DATA PROBES ARE MISSION-CRITICAL COMPONENTS FOR THE NEW GULFSTREAM G550 ATMOSPHERIC RESEARCH AIRCRAFT, SPECIFICALLY FOR THE MEASUREMENT OF THREE-DIMENSIONAL WIND VECTORS AND “TRUTH” PRESSURE DATA. THIS ACQUISITION IS VITAL FOR NOAA TO ACCOMPLISH ITS MISSION OF HIGH-ALTITUDE TROPICAL CYCLONE SURVEILLANCE AND ENVIRONMENTAL SAMPLING.

THE ROSEMOUNT 858AJ115 HEATED AIR DATA PROBE IS ESSENTIAL TO THE G550 ATMOSPHERIC RESEARCH MISSION. THIS SPECIFIC BRAND NAME ITEM FEATURES A UNIQUE FIVE-PORT HEMISPHERICAL HEAD GEOMETRY THAT ALLOWS FOR THE SIMULTANEOUS MEASUREMENT OF PITOT-STATIC PRESSURE, ANGLE OF ATTACK (Α), AND ANGLE OF SIDESLIP (Β). THESE FEATURES ARE ESSENTIAL FOR CALCULATING 3D WIND VECTORS IN THE TURBULENT ENVIRONMENTS OF TROPICAL CYCLONES. MARKET RESEARCH INDICATES THAT STANDARD "BRAND NAME OR EQUAL" PITOT-STATIC TUBES ARE DESIGNED FOR LEVEL-FLIGHT NAVIGATION AND CANNOT MAINTAIN CALIBRATION OR STRUCTURAL INTEGRITY AT THE HIGH FLOW ANGLES ENCOUNTERED DURING HURRICANE RECONNAISSANCE. WITHOUT THIS SPECIFIC BRAND NAME SENSOR, THE G550 WOULD BE UNABLE TO PROVIDE "TRUTH" METEOROLOGICAL DATA, RENDERING THE AIRCRAFT'S MULTI-MILLION DOLLAR SCIENTIFIC SUITE INCAPABLE OF MEETING NOAA’S MISSION REQUIREMENTS.

THE REQUIRED SUPPLIES MUST BE COMPATIBLE IN ALL ASPECTS (FORM, FIT, AND FUNCTION) WITH THE EXISTING G550 NOSE BOOM INSTRUMENTATION SYSTEM. THE G550 NOSE BOOM EXTENSION WAS SPECIFICALLY ENGINEERED, MACHINED, AND WEIGHT-BALANCED TO ACCEPT THE UNIQUE BOLT PATTERN AND PNEUMATIC PORT SPACING OF THE ROSEMOUNT 858AJ SERIES. FURTHERMORE, THE AIRCRAFT’S SPECIALIZED DE-ICING POWER BUS IS CONFIGURED TO INTERFACE WITH THE 115V AC INTERNAL HEATER ELEMENTS OF THIS EXACT MODEL. OTHER COMPANIES’ PRODUCTS, SUCH AS STANDARD COMMERCIAL PITOT TUBES, UTILIZE DIFFERENT MOUNTING FOOTPRINTS AND 28V DC HEATING ARCHITECTURES, WHICH CANNOT BE MODIFIED TO INTERFACE WITH THE G550’S RESEARCH-SPECIFIC NOSE BOOM AND ELECTRICAL RACKS WITHOUT EXTENSIVE AND COST-PROHIBITIVE AIRFRAME RE-ENGINEERING AND RECERTIFICATION

 THE 858AJ115 IS A HIGHLY SPECIALIZED, LOW-VOLUME INSTRUMENT USED ALMOST EXCLUSIVELY BY THE INTERNATIONAL ATMOSPHERIC RESEARCH COMMUNITY. AFTER AN EXHAUSTIVE MULTI-YEAR SEARCH, THE IDENTIFIED SOURCE IN VIRGINIA WAS FOUND TO BE THE ONLY VENDOR CURRENTLY CAPABLE OF PROVIDING THIS HARDWARE WITH THE NECESSARY FAA AIRWORTHINESS DOCUMENTATION (FORM 8130-3). THIS SOURCE WA IDENTIFIED THROUGH TECHNICAL COLLABORATION WITH THE GERMAN AEROSPACE CENTER (DLR), WHICH UTILIZES THE SAME PROBE ON AN IDENTICAL G550 PLATFORM. NO OTHER DOMESTIC SOURCE WAS FOUND CAPABLE OF PROVIDING A SENSOR THAT MEETS THE REQUIRED SAMPLE RATES AND ENVIRONMENTAL TOLERANCES AT THE LEVEL OF QUALITY NECESSARY FOR HIGH-ALTITUDE SCIENTIFIC RESEARCH.

DELIVERY WITHIN 80 WEEKS FROM DATE OF AWARD
