PSC L015

Overview

The Product Service Code (PSC) system is the government-wide taxonomy used to classify products and services purchased through federal contracting, improving FPDS/SAM reporting, spend analysis, and program-level tracking; the PSC list and maintenance process are published in the PSC Manual.¹ PSC L015 — Technical Representative‑ Aircraft And Airframe Structural Components — identifies services that assign technical‑representation functions specifically related to aircraft structural elements. This entry sits in Category L (Technical Representative) and is the authoritative descriptor for FPDS coding when a designated technical representative performs non‑contract‑administration technical duties for airframe structures, including inspections, acceptance testing, and engineering oversight.¹

What this PSC covers

• Technical‑representative services for airframe structural inspections and assessments.
• On‑site liaison and engineering oversight at contractor facilities.
• Technical acceptance and verification of structural component performance.
• Support for maintenance, repair, modification, or acceptance testing of airframe structures.
• Interface between program office and contractor on structural configuration/control issues.
• Documentation review and approval related to structural repairs or alterations.

Typical procurement contexts

Program offices assign PSC L015 when contracts require a designated technical representative (TR) to perform non‑contract‑administration technical duties (for example, in‑service engineering, on‑site inspections, or acceptance testing) at or near contractor facilities; this use aligns with PSC coding guidance in the PSC Manual for TR services that are specific to aircraft airframe structures.¹

Role of the technical representative (TR)

A TR performs non‑CAS (non‑contract administration service) technical duties and serves as the technical agent for a program or project office but is distinct from a Contracting Officer’s Representative (COR); DFARS Subpart 242.74 defines TR procedures, duties, and limits (for example, TRs are not delegated contracting authority).²

Frequently asked questions

• Q: When should a requirement be coded as PSC L015 rather than a different L‑series code?

  • A: Use PSC L015 when the predominant service is technical‑representation specifically for aircraft or airframe structural components; adjacent L‑codes apply to other equipment families (for example, L016 covers aircraft components and accessories).¹

• Q: Does assigning a TR change contracting authority or allow scope changes?

  • A: No. A TR provides technical oversight and guidance but is not authorized to direct changes that alter contract scope, price, or terms; contracting authority, and formal scope changes, remain with the contracting officer and follow DFARS/agency procedures.²

• Q: How is PSC L015 reported on contract line items?

  • A: Enter the PSC for the predominant product or service in FPDS data element 8A at the line‑item level; CLINs and subline items that separately price TR services should include the appropriate PSC per CLIN reporting guidance in the PGI on CLIN/PSC use.³

• Q: Are there standard qualifications for personnel performing TR duties under L015?

  • A: Minimum qualifications or competencies vary by agency and contract complexity; official acquisition regulations describe appointment and delegation procedures, but there is no single government‑wide qualification matrix. Not specified by official sources.²

Related NAICS and PSC codes

• NAICS (commonly associated)

  • 336411 — Aircraft Manufacturing — used when the principal effort is production or major OEM airframe manufacturing.
  • 541330 — Engineering Services — used when the predominant work is engineering, analysis, structural assessments, or in‑service engineering support.
  • 488190 — Other Support Activities for Air Transportation — applicable when the primary services are operational support tied to air transportation activities (logistics/field support).

  • L014 — Technical Representative - Guided Missiles
  • L015 — Technical Representative - Aircraft And Airframe Structural Components
  • L016 — Technical Representative - Aircraft Components and Accessories
  • L059 — Technical Representative - Electrical And Electronic Equipment Components

Guidance: select the NAICS that reflects the contract’s predominant effort (manufacturing vs. engineering vs. support) and use PSC L015 to identify the technical‑representation service for aircraft airframe structural components at the CLIN level where that TR work is priced.
