What a federal aviation grant reviewer checks before the technology

What was broken

An aviation-sector company needed growth capital and a funding application that presented its plan credibly to a seed-fund committee.

What we did

CapEasy prepared the seed-fund proposal — business plan, budget, and projections aligned to the scheme — and structured the application to the eligibility and permitted-spend rules.

Where it landed

The company secured a public seed-fund approval. A seed-fund approval is the committee’s sanction; actual disbursement follows the scheme’s due-diligence and compliance milestones and is not guaranteed.

The door built for aviation is inside DOT, not a separate FAA fund

The FAA does not run its own SBIR program. Aviation-sector non-dilutive money in the US runs through the Department of Transportation's SBIR program, administered out of the Volpe National Transportation Systems Center, with the FAA as one of the participating modal administrations alongside FHWA, FRA, FTA, NHTSA and PHMSA in cycles where it has open research needs — aviation safety, unmanned aircraft systems integration and airport-adjacent technology have all appeared as DOT SBIR topic areas in recent solicitations. Which modes are open, and which specific topics they post, resets every fiscal year: the FY26 pre-solicitation period ran April 29–May 29, 2026 with the Phase I solicitation closing July 7, 2026, and the live Appendix A on Volpe's site is the only place to confirm whether a given cycle has an aviation-relevant topic before you write anything.

DOT's own award ceilings are not the generic SBIR figure most founders quote. The government-wide SBA thresholds other agencies use run to $323,090 for Phase I and $2,153,927 for Phase II — but DOT sets its own, smaller numbers: FY26 Phase I awards top out at $200,000 for a six-month period of performance, and Phase II — open only to firms that already hold a DOT Phase I award — runs to roughly $1,500,000 over about two years. Sizing a budget to the wrong ceiling is a fast way to look like you have not read the solicitation you are answering.

The program itself is not going anywhere: SBIR and STTR lapsed on September 30, 2025 and were reauthorized through fiscal year 2031 when the Small Business Innovation and Economic Security Act (S.3971) was signed into law on April 13, 2026 — current authority, not a program a founder needs to worry about disappearing mid-application.

You get paid when DOT accepts your report, not on your invoice date

DOT structures its SBIR Phase I awards as Firm-Fixed-Price contracts, and payment is tied to deliverables, not a calendar. A Phase I award requires three progress reports — two bi-monthly reports plus a final report — and DOT pays out only on acceptance of each one. That is a materially different cash-timing risk than a typical services contract: the money does not move on the date you submit an invoice, it moves on the date a federal reviewer signs off on your report, and a report that gets kicked back for revision pushes the payment date with it.

For an aviation-services company that also runs ordinary billable work — maintenance, inspection, logistics or charter operations — alongside a Phase I award, that means two different cash-recognition rhythms have to sit in the same set of books without blurring into each other: one revenue stream that follows normal invoice-to-payment timing, and one that only recognises cash on report acceptance. A forecast that treats DOT SBIR income as "cheque arrives net-30" will be wrong in a way that shows up as a cash gap, not a rounding error.

The cost segregation a reviewer — and later an auditor — will test

Every dollar in a DOT SBIR budget has to be reasonable, allocable and allowable under the federal cost principles at 2 CFR Part 200 Subpart E, and SBIR.gov's own accounting guidance lays out what an approved system has to demonstrate before or shortly after award: direct costs kept separate from indirect costs, direct costs accumulated by contract, a consistent method for allocating overhead, cost accumulation under general-ledger control, and a formal timekeeping system where every person on the award — including the founder — logs actual hours daily against the specific contract, not an end-of-month estimate.

In an aviation-services business this is the same discipline the industry already half-practises for other reasons — job costing by aircraft, tail number or work order is standard in MRO and charter operations — except the SBIR award has to be its own cost object, cleanly separable from every other job on the shop floor. Labor hours spent on the funded R&D task, parts and test costs tied to that task, and any subcontracted repair or flight-test work all need to trace to the award's own line items. A shop that books everything to one "operations" account, and only splits it out at tax time, is exactly the profile that reads as unready when a reviewer — or later a program officer checking the final report against the budget — asks where the money actually went.

The discipline the engagement already proved

The mechanism was different — a seed-fund committee weighing a seed-stage grant against registered-entity eligibility and permitted-spend rules — but the underlying test was the same one a DOT SBIR reviewer runs: does the budget hold together as a document a committee can underwrite against its own spend rules, not just a plan a founder can narrate out loud. Structuring the application to the scheme's own eligibility and permitted-spend rules, line by line, is what cleared the seed-fund committee, and it is what clears a DOT reviewer.

CapEasy prepares that file: the cost segregation, the budget built to the award ceiling that actually applies, the books set up so award-linked cash and ordinary services revenue never blur together. Filing the SBIR proposal itself, any government-facing cost representations, and returns or attest work run through partner CPA firms across 15 US states — the eligibility and award decisions belong to DOT and your counsel.
