About this file
This is a comment matrix and FAA responses document addressing questions and clarifications regarding the Continuous Lower Energy, Emissions and Noise (CLEEN) Phase IV Program Solicitation for Research (SIR). The document provides official FAA guidance on key eligibility, submission, and programmatic requirements for respondents.
Key clarifications include: respondents must be U.S.-incorporated entities that primarily operate and manufacture substantially within the United States, following 2 CFR 200.322 requirements for any non-U.S. products or services with appropriate justification; page limits for proposal factors are strictly per-project (7 pages maximum per project for Factor 2 and 5 pages per project for Factor 3) and cannot be reallocated across multiple projects; the three required recent and relevant projects for corporate experience must be performed by the prime respondent, not team members or subcontractors; a separate task plan is not required beyond the technical approach plan submitted under Subfactor 3.1; all facilities, whether internal or external, require commitment letters from facility managers; the period of performance begins on the award date, with no flexibility for projects requiring shorter than 24-month durations to start later; government agencies are ineligible as team members and cannot receive FAA funding as recipients, subrecipients, contractors, or subcontractors, though non-federal cost share may be used to engage government agencies as contractors; and no travel report template is provided—respondents must follow the requirements detailed in SIR Section 12.4. The proposal submission deadline is May 18, 2026, with anticipated awards planned for September 2026.

Comments
| Document | Page/Tab | Section/Para/Cell | Text | Comment | Rationale | FAA Reponse |
| CLEEN IV SIR | Page 4 | Eligibility Requirement in Section 4 | If a portion of the final manufacturing product is not completed in the U.S., does that disqualify the proposal? | Refer to SIR Section 4, Eligibility. "Respondents must follow 2 CFR § 200.322. If, to the greatest extent practicable under Section 200.322, a U.S. product or service will not work for the project, then respondents must provide justification for the use of a non-U.S. product or service." | ||
| CLEEN IV SIR | Page 21 | 9.10.1 Volume 1 – Technical/Management Proposal | The SIR states: The page limit for Factor 2 is no more than seven (7) pages per each proposed CLEEN IV Technology Project and no more than five (5) pages per each proposed CLEEN IV Technology Project for Factor 3. | Can the offeror allocate total pages across multiple projects as it deems appropriate for Factor 2 as well as for Factor 3 within the specified total page count for each Factor? For example, if the offeror proposes 2 projects, can Project 1 be allocated with 10 pages and Project 2 be allocated with 4 pages for Factor 2, holding to the total count of 14 pages for 2 proposed projects. | No. Respondents must keep to the per project page limits presented in the SIR. | |
| CLEEN IV SIR | Page 4 | Eligibility requirements under Section 4 | The SIR document stating that "Respondents to this SIR must be incorporated in the United States (U.S.), primarily operate within the United States, and manufacture their products substantially within the United States." | Would a US-incorporated lead participant proposing a project that includes subcontracted manufacturing from a non-US supplier - with appropriate 2 CFR § 200.322 justification - meets the eligibility requirements of Section 4 of the SIR document? | Refer to SIR Section 4, Eligibility. "Respondents must follow 2 CFR § 200.322. If, to the greatest extent practicable under Section 200.322, a U.S. product or service will not work for the project, then respondents must provide justification for the use of a non-U.S. product or service." | |
| CLEEN IV SIR | Page 15 | 8.7.1 Schedule | The Deliverable Schedule in Section 8.7.1 of the SIR states that the initial Task Plan is due "with proposal," with a revised final plan due 30 days after task initiation. However, the Proposal Preparation Instructions in Section 9.10 do not reference the Task Plan as a component of the proposal submission, and it is not listed among the required proposal volumes in Section 9.1. | Is an initial Task Plan required as part of the proposal submission on 18 May 2026? If so, is the Task Plan subject to any format or page limit requirements, or should it follow the general formatting instructions in Section 9.10? Does the Task Plan count toward the page limits for any of the proposal volumes? | A "Task Plan" is not required separate from the plan required under Subfactor 3.1, Technical Approach. The plan submitted under Subfactor 3.1 will serve as the basis for the company-specific Statement of Work (SOW) to be submitted by the Participant if selected (see Cooperative Agreement Article II, Subparagraph C, Scope). | |
| CLEEN IV SIR | Page 37 | 12.4 Reimbursement for Travel and Subsistence | 12.4 – “Reimbursement for Travel and Subsistence”, under subsection (c) | Is there a “template” for the travel report that the FAA will provide? | There is no template. SIR Section 12.4 details the required information. | |
| CLEEN IV SIR | Page 27 | Section 10.2.1: Factor 1, Corporate Experience | To receive a rating of 'Pass', the Respondent must provide at least three (3) recent and relevant projects. | (a) Can projects performed by team members (subcontractors or partners) be submitted toward the three-project requirement, or must all three projects have been performed by the prime Respondent? (b) For key personnel who have directly contributed to relevant projects at prior organizations, can that experience be submitted toward the Respondent's corporate experience requirement? | The SIR defines "recent" and "relevant" but does not specify whether the three projects must have been performed by the prime Respondent entity or whether team member and key personnel experience at other organizations qualifies. | Project must have been performed by the prime Respondent. |
| Page 20 | 9.9 Acquisition Milestones | We acknowledge awards are planned for September of 2026 | However can projects requiring a shorter than 24 month duration start later than the September award date? | The period of performance begins on the date of award of the agreement. | ||
| CLEEN IV SIR | Page 26 | Section 10.1 | Proposal Selection paragraph 5 states : “Government agencies and Federally Funded Research and Development Centers are not eligible to submit proposals under this SIR or participate as team members under proposals submitted by eligible entities | Can you clarify the financial relationship of a “team member”? Is it acceptable if a government agency is paid as a subcontractor to leverage facility capabilities? | A government agency is not permitted to participate as a team member under the proposal. A government agency may not be paid with FAA funds as a Recipient, Subrecipient, contractor, or subcontractor. Participant cost share that is not paid by the Federal Government under any Federal award may be used to pay a government agency as a contractor. Refer to 2 CFR 200.331, Subrecipient and contractor determinations, to determine if an entity is considered a contractor under a CLEEN IV award. | |
| CLEEN IV SIR | Page 25 | Section 2 | Proposed Respondent Contribution – states that the use of facilities requires certain information. Subparagraph (4) states: “letter of commitment from the facility manager”. | Is the requirement for this letter of commitment for external source facilities only or is the letter also required for internal source facilities? | All facilities. | |
| CLEEN IV SIR | Page 4 | Section 4 requirement to follow 2 CFR 200.322 | Can a US company utilize internal engineering expertise on a limited basis at a global location? | Refer to SIR Section 4, Eligibility. "Respondents must follow 2 CFR § 200.322. If, to the greatest extent practicable under Section 200.322, a U.S. product or service will not work for the project, then respondents must provide justification for the use of a non-U.S. product or service." | ||
