About this file

Written by GovTribe AI ·

The document is a detailed specifications sheet for aircraft rack components for the NOAA Chemical Sciences Laboratory. The specifications outline precise manufacturing requirements for 12 aircraft-certified instrument racks, including 48 unique aluminum parts made from 6061 and 7075 aluminum alloys. Each component has specific surface roughness tolerance of 125uin/3.2um Ra or better, with a dimensional tolerance of +/- .005" (+/- 0.13mm). The parts include corner uprights, frame members, machined parts, and sheet metal parts, ranging from rectangular tubes to L-fittings and splice plates.

The components are part of a federal contract opportunity (Solicitation Number 1305M325Q0184IV) issued by the Department of Commerce's National Oceanic and Atmospheric Administration (NOAA) for the Chemical Sciences Laboratory. The rack components are critical for the upcoming AiRMAPS (Airborne and Remote sensing Multi Air Pollutant Surveys) field campaign, designed to be used on NOAA P-3 aircraft. The solicitation requires delivery within 4 weeks after award, with parts to be delivered to Boulder, Colorado. The contract is an unrestricted, low-price technically acceptable procurement with a small business size standard of 1,250 employees, with a quote submission deadline of 7/18/2025.
