STATEMENT OF NEED

AIRCRAFT DIAGNOSTIC AND TEST EQUIPMENT - AOC

Requisition Number 140808-26-0008

PURPOSE: The purpose of this initial provisioning action is to support NOAA’s Aircraft Recapitalization Plan by purchasing aircraft diagnostic and test equipment to maintain the new Gulfstream 550 SP aircraft. This aircraft will replace the aging and obsolete G-IV SP aircraft currently in use. Current avionics test and diagnostic equipment will not interface with the 550 SP platform due to advances in technology and improvements in aircraft wiring, components and instruments. Therefore, the obsolete diagnostic and test equipment must be replaced in order to maintain federally mandated aircraft maintenance requirements and operational standards. The Aircraft Operations Center’s (AOC) maintenance and operational support costs will be reduced measurably by possessing the capability this equipment provides. Additionally, maintaining the aircraft in an airworthy condition is required by the Federal Aviation Administration, Title 14, Code of Federal Regulations (14 CFR) Part 91 and Part 43.

SCOPE OR MISSION: Due to the inherent safety requirements of maintaining aircraft avionics and electrical components including instruments, communication and navigation equipment, it is critical that specifically designed and calibrated equipment be utilized in the testing, certification and maintenance of the G550 SP aircraft. Lack of the appropriate equipment in the proper amounts will degrade the operational performance and capability of NOAA’s high altitude weather reconnaissance and research aircraft. This loss of performance will negatively impact the weather data collected and significantly impact the National Weather Service and National Hurricane Center’s ability to provide detailed weather information to millions.
