NASA's twin-engine Dehaviland research aircraft requires upgraded avionics for present and future research missions, according to contract documents released Friday by the agency. The aircraft, based at Glenn Research Center in Cleveland, Ohio, is a preproduction model that is utilized for various airborne research missions. A work site within 150 nautical mile radius of Cleveland is required due to government oversight personnel schedule.
Also known as a Twin Otter, the plane is a DHC-6 series 100 serial number 4 research aircraft (tail number N607NA).
“NASA Glenn Research Center will transport the aircraft to and from the contractor work site at a date and time determined by the technical manager and pilot, after consultation with the contractor,” the agency said in contract documents. “Period of performance end date shall be four months after receipt of order and aircraft. The goal of this task is an upgrade of NASA GRC's DHC-6 Twin Otter research aircraft with digital avionics suite. This hardware upgrade will be used initially for the remote sensing research mission and for future research missions.”
Companies interested in performing the upgrade should submit an offer by May 16 to be considered by the agency. All contractual and technical questions must be submitted by May 13.
