PSC 2935

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy that classifies the goods and services purchased by U.S. agencies so awards in systems such as FPDS and SAM.gov can be tracked, analyzed, and reported consistently. The PSC Manual governs the structure, definitions, and reporting guidance for these codes. ¹

PSC 2935 — Engine System Cooling Components, Aircraft Prime Moving — covers cooling system components specifically designed for aircraft and/or guided‑missile prime movers. Official inclusions list radiators, cooling system pumps, water hose assemblies, lubricating oil coolers and control valves, and oil temperature regulators; items not specifically designed for aircraft engines are excluded. ¹

Scope boundaries and exclusions

• Applies only to cooling components for aircraft or guided‑missile prime movers; non‑aircraft engine cooling components belong in 2930. ¹
• Fuel system parts are not in 2935; use 2915 for aircraft/missile fuel system components. ¹
• Electrical/ignition items are excluded; use 2925 for aircraft engine electrical components. ¹
• Air and oil filters/strainers/cleaners fall under 2945 when for aircraft prime movers. ¹

Frequently asked questions

• What items are explicitly included under PSC 2935?
  The manual lists radiators, cooling system pumps, water hose assemblies, lubricating oil coolers and control valves, and oil temperature regulators, but only when specifically designed for aircraft or guided‑missile prime movers. Items for non‑aircraft engines are excluded. ¹
  See also on G2X — PSC 2935 overview.

• How does 2935 differ from 2930?
  2935 covers cooling system components for aircraft or guided‑missile prime movers, while 2930 applies to cooling components for non‑aircraft engines. Use 2935 when the component is aircraft or missile‑specific by design; otherwise consider 2930. ¹

• Does PSC 2935 apply to guided‑missile engines as well as aircraft engines?
  Yes. The class expressly includes cooling system components for aircraft and/or guided‑missile prime movers. Components must be part of the engine cooling function (e.g., radiators, pumps, oil coolers), not general environmental or cabin cooling systems. ¹

• Where is the PSC captured in federal reporting systems?
  PSC is recorded for contract action reporting and is reflected in FPDS and SAM.gov’s Contract Data resources used by agencies and the public for award visibility and analysis. ³

• Which NAICS codes map to PSC 2935?
  Not specified by official sources. Agencies select NAICS based on the principal purpose of the acquisition; there is no authoritative one‑to‑one mapping from PSC to NAICS for this class. ²
