3.3.1-40 Electronic Submission of Payment Requests (INTERIM December 2025)

(a) Definitions. As used in this clause—

(1) “Contract financing” is a contractual authorization for payments to a contractor prior to acceptance of products or services by FAA.

(2) “Payment request” means a bill, voucher, invoice, or request for contract financing payment or invoice payment with associated supporting documentation. The payment request must comply with the requirements identified in this clause and the applicable Payment clause and invoicing requirements included in this contract.

(3) “Electronic form” means an automated system transmitting information electronically according to the accepted electronic data transmission methods and formats identified in paragraph (c) of this clause. Facsimile, email, and scanned documents are not acceptable electronic forms for submission of payment requests.

(4) “Invoice payment” means a Government disbursement of monies to a contractor under a contract or other authorization for supplies or services accepted by the Government. This includes payments for partial deliveries that have been accepted by the Government, final payments under T&M and labor-hour contracts, and final cost or fee payments where amounts owed have been settled between the Government and the contractor.

(b) Electronic payment requests. Except as provided in paragraph (f) of this clause, the Contractor must submit payment requests in electronic form. Purchases paid with a Government purchase card are considered to be an electronic transaction for purposes of this rule, and therefore no additional electronic invoice submission is required.

(c) The Federal Aviation Administration utilizes the Delphi eInvoicing web-portal for processing invoices.

Contractors submitting invoices are required to submit invoices via the Delphi eInvoicing web portal which is accessed and authenticated via www.login.gov

(d) In order to receive payment and in accordance with prompt payment standards, the Contractor must submit a proper invoice. All invoices submitted as attachments in the Delphi eInvoicing web-portal must contain the following:

(1) Invoice number and invoice date.

(2) Period of performance covered by invoice.

(3) Contract number and title.

(4) Task/Delivery Order number and title (if applicable).

(5) Amount billed (by CLIN), current and cumulative.

(6) Total ($) of billing.

(7) Cumulative total billed for all contract work to date.

(8) Name, title, phone number, mailing address, and email address (if available) of person to be contacted in the event of a defective invoice.

(9) The following statement: “The Contractor certifies that, by submitting this invoice to the FAA, the supplies and/or services billed have been shipped, rendered, or delivered in accordance with instructions issued by the ordering officer; that they are reflected in the quantities and/or period of performance stated on the invoice; and that such supplies and/or services conform to the quantity and quality requirements specified in the applicable contract, order, or blanket purchase agreement.

(10) The following statement: “Pursuant to Executive Order 14173, Ending Illegal Discrimination And Restoring Merit-Based Opportunity, the Contractor certifies that it is in compliance with the Equal Protection principles of the Constitution and all applicable Federal anti-discrimination laws, and acknowledges that such compliance is material to the Government’s payment decision under the False Claims Act (31 U.S.C. § 3729(b)(4)). The Contractor also affirms that it does not operate any diversity, equity, and inclusion (DEI) initiatives that are inconsistent with the Equal Protection principles of the Constitution and the non-discrimination requirements of Federal law, as interpreted by the Supreme Court in Students for Fair Admissions v. Harvard, 600 U.S. 181 (2023).”

Note: the statement in item (10) in the preceding list is only required for invoices submitted to receive payment for contract performance occurring after this AMS clause 3.3.1-40 Electronic Submission of Payment Requests (INTERIM December 2025) is included in the contract.

If the contract includes allowances for travel, all invoices that include charges pertaining to travel expenses must catalog a breakdown of reimbursable expenses with the appropriate receipts to substantiate the travel expenses.

(e) Payment system registration. Each person accessing the Delphi eInvoicing web-portal will be required to have a unique user Delphi eInvoicing ID and password and be credentialed through login.gov.

(1) Electronic authentication. See www.login.gov for instructions. Click on the following link for instructions on establishing a login.gov account: https://login.gov/help/creating-an-account/how-do-i-create-an-account-with-logingov/.

(2) To create a login.gov account, the user will need a valid email address and a working phone number. The user will create a password and then login.gov will reply with an email confirming the email address.

(3) DELPHI registration instructions. New users should request access to Delphi eInvoicing by sending an email to 9-AMC-FAA-iSupplier@faa.gov. Once access is to activate the account. Users are required to log in every 45 days to keep it active. Once access is granted, users should navigate to http://einvoice.esc.govto activate the account.

Users are required to log in every 45 days to keep it active.

(4) Training on DELPHI. To facilitate use of DELPHI, comprehensive user information is available athttp://einvoice.esc.gov

(5) Account Management. Contractors must contact the DELPHI Help Desk when their firm’s points of contact will no longer be submitting invoices so they can be removed from the system. Instructions for contacting the DELPHI Help D can be found athttp://einvoice.esc.gov

(f) Waivers: If the Contractor does not believe electronic invoicing can be used if they are awarded this contract, the Contractor must respond accordingly to AMS clause 3.3.1-41 Electronic Invoicing-Representation. Waiver requests must be approved by the FAA and DOT and will be processed expeditiously upon contract award. If the waiver request is not approved, the Contractor must use electronic invoicing consistent with this clause. If the waiver request is approved, conversion to electronic invoicing at a later date may be required. While the waiver is in effect, the current invoicing process must be used per AMS Guidance T3.3.1A.14 and the terms of the contract. The decision regarding a waiver request is not subject to AMS clause 3.9.1-1 Contract Disputes.

3.8.9-8 Certification of Accuracy and Disclosure of Artificial Intelligence (AI) Use

(a) The following certification must be checked:

The Contractor (including any subcontractors or agents acting on its behalf) [ ] certifies [ ] does not certify that all information, data, statements, analyses, and representations contained in, or submitted in connection with, any proposal, report, deliverable, or other written submission to the Federal Aviation Administration (FAA) under this contract are accurate, complete, and based on reasonable verification or substantiation to the best of the Contractor’s knowledge and belief.

(b) Definitions.

“Artificial Intelligence” or “AI” means a machine-based system that can, for a given set of human-defined objectives, make predictions, recommendations or decisions influencing real or virtual environments. Artificial intelligence systems use machine and human-based inputs to (A) perceive real and virtual environments; (B) abstract such perceptions into models through analysis in an automated manner; and (C) use model inference to formulate options for information or action. Examples of AI use can include software, models, or systems that perform tasks by automated reasoning, learning, pattern recognition, or decision-making, including but not limited to large language models, generative models, automated drafting, data-analysis tools, and machine learning models.

“Hallucinated Data” means any assertion, citation, statement, or data element in a deliverable that (i) is factually inaccurate, fabricated, or materially misleading, and (ii) is not supported by or is contradicted by FAA-provided source materials or other mutually agreed authoritative sources, such as industry standards or peer-reviewed publications, as of the Delivery Date.

“Confirmed” means that the issue has been agreed in writing by the parties or determined by an independent expert, selected according to mutually agreed criteria, after a reasonable opportunity for review.

(c) If any portion of any submission is prepared, drafted, or substantively generated by or with the assistance of Artificial Intelligence (AI) technologies—including, but not limited to, large language models, generative AI, automated drafting, data analysis tools, or machine learning models—the Contractor must disclose in writing and separately identify in the submission:

1. The sections, data, or content that were prepared, drafted, or substantively generated by or with the assistance of AI;

2. The AI tool(s) used and their general function(s) (including model name/version where available); and

3. The validation measures applied to the AI-generated content (e.g., human review, testing, grounding to source materials), and (if relied upon) citations to FAA-provided or other authoritative source materials used for grounding. The Contractor may redact proprietary implementation details so long as those details are made available to the FAA under appropriate confidentiality terms upon request.

(d) Where AI technology is used, the Contractor affirms that it has reviewed, validated, and taken full responsibility for the AI-assisted content’s factual and technical accuracy, reliability, and appropriateness as described in paragraph (b). The Contractor remains fully liable for errors, misrepresentations, fabrications, or “hallucinated” data, regardless of the generation method.

(e) The Contractor understands that submission of false, misleading, or fabricated information—whether AI-generated or otherwise—may result in contract remedies including, but not limited to, rejection of deliverables, withholding of payment, contract termination for default, or suspension/debarment, as well as any remedies available at law or equity.

(f) Correction, investigation, and expert determination. The Contractor must, at its sole expense, correct any errors, misrepresentations, fabrications, or Hallucinated Data in Deliverables within seven (7) business days of receipt of written notice from the FAA that specifies the alleged items and provides supporting evidence. The Contractor must investigate and respond within seven (7) business days. If the parties cannot agree whether an item is Confirmed, either party may refer the matter to an independent expert for determination in accordance with procedures set forth elsewhere in this contract or as mutually agreed.

(g) Evidence preservation and audit. The Contractor must preserve and make available to the FAA, for a period of two (2) years following delivery, relevant evidence sufficient to investigate alleged issues, including model identifiers and versions, prompts and system messages, input data and retrieval traces, and relevant logs, subject to confidentiality obligations and applicable law. The FAA may audit compliance upon reasonable notice and in accordance with AMS 3.2.2.3-8 Audit and Records (July 2010); if a material non-conformance is found, the FAA may invoke remedies as provided elsewhere in this contract.

(h) The substance of this clause must be included in all subcontracts at any tier under this contract.

(End of clause)

3.8.9-9 Certification and Disclosure of AI Usage in Proposal Submissions

The Offeror certifies [ ] does not certify [ ] that all information and data provided in its proposal and supporting material are, to the best of its knowledge and belief, true, accurate, complete, and based on reasonable verification or substantiation. If any material content in the proposal has been generated in whole or in part by or with the assistance of Artificial Intelligence (AI) technologies, the Offeror discloses such usage in the proposal, including the sections involved, the types of AI technologies used, and the steps taken to verify the accuracy and reliability of the AI-generated content. The Offeror accepts full responsibility for the factual accuracy and intellectual integrity of all information submitted.

(End of provision)
