On-field aviation MRO subcontracting at CVG — specialty NDT, composite and sheet-metal repair, ground support equipment repair, interior refurb, and ramp-tenant compliance services feeding FEAM Aero, the new DHL maintenance facility opening January 2026, L2 Aviation's April 2025 grand opening, and the Safran-anchored aerospace cluster.

Three things make this a Boone-only candidate. First, the anchor concentration is recent and documented. DHL's $292 million, 305,000-square-foot aviation maintenance facility broke ground in October 2024 and opens January 2026 with 300 new technician and support jobs. FEAM Aero's $45 million three-bay 767-capable hangar opened in March 2024 with 250 full-time positions, including 124 Kentucky-resident jobs. L2 Aviation's $12.2 million Boone facility opened April 16, 2025 with 250 hires planned through 2026. Safran's $65 million Walton expansion supports a Boeing-driven carbon-brake capacity ramp from about 140,000 to 210,000 disks per year. Three step-function shocks landed inside an 18-month window, and incumbents have not yet been re-bid against the new capacity.

Second, the Kentucky-side specialty bench is thin. The public AS9100 directory at machineshop.directory shows one Kentucky-certified shop — Victor Enterprises in the Paducah and Owensboro region, far western Kentucky. We have not yet pulled the authoritative IAQG OASIS supplier registry, but cross-references to Northern Kentucky chamber rosters and Tristate Aerospace Alliance membership match the thin reading. The Northern Kentucky aerospace primes pull most of their Tier-2 supplier capacity from Cincinnati-side Ohio shops including Valence Surface Technologies and Metal Chem. For emergency non-destructive testing, wrench-on-the-ramp ground support equipment work, and ramp-tenant glycol compliance, Cincinnati travel costs and ITAR-controlled handling create a real Kentucky-side opening.

Third, be honest about which sub-lanes are actually winnable. FEAM Aero runs 36 locations and 1,300 technicians; it likely keeps non-destructive testing, composite repair, and avionics-line work in-house at scale. The lanes where a Boone-headquartered entrant has a real advantage are interior refurb, ground support equipment repair, aircraft cleaning, ramp-tenant glycol compliance, and emergency-call non-destructive testing. For specialty non-destructive testing field crews, the regulatory moat is NAS 410 Level II/III, NADCAP AC7114, and ASNT SNT-TC-1A. For the lower-tier services the moat is proximity plus an FAA Part 145 certificate plus named-customer past-performance built over 12 to 24 months of subcontract work to FEAM, L2 Aviation, AMES, or the cargo-carrier line operations.

Adjacent lanes a Boone-headquartered specialty operator could expand into include IATA dangerous-goods lithium-battery packaging and repack services (CVG is one of the few U.S. airports with both DHL Americas Hub and Amazon Air primary on a single field), bonded drayage through Foreign Trade Zone 47 (which covers Boone, Kenton, and Campbell at about $10.2 billion in annual volume), and Airframe-and-Powerplant mechanic staffing through the FEAM-Epic Flight Academy school at CVG. Each carries its own regulatory framework — FAA Part 145, IATA Dangerous Goods Regulations, U.S. Customs bonded carrier with TSA Indirect Air Carrier and CTPAT, FAA drug-and-alcohol testing under 14 CFR Part 120 for staffing.

Revenue benchmark range (specialty MRO subcontractor — NDT, composite/sheet-metal, GSE repair, interior refurb): $400K (single-cert NDT solo + 1 helper) to $2.5M (multi-tech Part 145 with FAA and customer audit history). Gross margin 35–55% (labor-heavy; NDT consumables low; composite materials drag margin). SDE margin 18–28% of revenue once owner is W-2 lead inspector.

SDE multiple — federal-aerospace past-performance is the moat, so SDE multiples sit at 2.5–4.0× SDE; EBITDA at 3.5–7.0× for niche specialty. Industry rules of thumb: aviation services trade approximately 0.8–1.2× revenue. Capital range for entry: $250K (NDT-only mobile rig + IRP-9 method documentation + calibration) to $700K (small fixed Part 145 with hangar lease, two-bay shop, NADCAP AC7114). FAA Part 145 certification timeline 8–18 months (6–12 months optimal; established station adding rating 60–90 days).

Worked example: SBA 7(a) at $400K / 11.5% / 10-year amortization runs approximately $5,600/month or $67,000/year debt service. Requires approximately $110,000 SDE for 1.5× DSCR after owner draw. At $1.5M revenue and 22% SDE = $330K SDE − $67K debt service = approximately $263,000 owner take-home in steady state. Year-three target with two-tech specialty NDT crew + FAA Part 145 cert + one anchor master-service-agreement is plausible.

A&P mechanic compensation benchmarks for the CVG market: start ~$28–35/hour post-A&P (FEAM published rates), senior $40–55/hour, lead inspector $90,000–$130,000, NDT Level III $110,000–$150,000. Service Contract Act prevailing-wage applies on federal-pass-through work. Inputs: BizBuySell aviation-services SDE multiples 2024–25; RMA NAICS 488190, 336412, 336413; SBA 7(a) at ~11% on a 10-year term; FAA Part 145 certification timeline documentation; First Page Sage aerospace EBITDA & valuation multiples 2025.

The acquisition lane here is thin in Boone today. Most CVG MRO labor is W-2 to FEAM, AMES, L2 Aviation, Safran, IDS, or Menzies; specialty subcontractors that travel into CVG are out-of-area firms based in Texas, Florida, Ohio, or New Jersey. We do not see a Boone-headquartered small Part 145 specialty shop in the FAA directory or chamber rosters today. A full FAA Part 145 pull for Boone-area ZIP codes (41005, 41011, 41014-41018, 41042, 41048, 41051, 41074, 41091, 41094) is the verification we still need.

The realistic operator path is **build, not buy**. Either FAA Part 145 certification from scratch (8–18 months timeline) or acquire a stalled out-of-area Part 145 cert holder and relocate the cert to a Hebron, Erlanger, or Florence shop. Cert-transfer mechanics typically run a 60–90-day rating-add timeline once acquired. National listings on BizBuySell aviation NAICS 488190, 336412, 336413 are the search channel. Buying a stalled Part 145 with documented past-performance at a Tier-2 cargo or military customer can compress the ramp from 18 months to 6 months.

Adjacent acquisition target: a Boone-headquartered small specialty industrial-services firm under NAICS 561210 (facilities support) or 488190 (other air-transport support) with bonding capacity and a logistics-trades labor pool — buy and pivot toward FAA Part 145 certification. A Kentucky Secretary of State bulk pull on Boone-resident NAICS 561210, 488190, 336412, and 336413 entities is the next step. No specific named target today.

• — We have not talked to FEAM Aero's procurement team. Which specialty sub-categories FEAM outsources today versus keeps in-house is the biggest single unknown.
• — We have not talked to DHL Express Americas Hub procurement. Whether the new maintenance facility's specialty subcontract scope is locked to a national vendor master file or carries a local lane is open. The January 2026 opening leaves a narrow onboarding window either way.
• — We have not talked to L2 Aviation supplier registration. The Boone-facility-specific AS9100D supplier flowdown contact and scope are not yet in hand.
• — We have not talked to Safran Walton supplier quality. Whether the $65 million expansion increases or decreases local Tier-2 demand depends on how much of the carbon-brake capacity ramp is captive versus outsourced.
• — We have not pulled the FAA Part 145 directory for Boone ZIP codes 41005, 41011, 41014, 41017, 41018, 41048, 41051, 41074, 41091, and 41094. The count of any Boone-headquartered Part 145 specialty shops (likely zero to three) decides whether the acquisition lane is closed or partly open.
• — We have not pulled the NADCAP supplier directory for Kentucky-resident AC7114 non-destructive testing accreditations, or cross-referenced IAQG OASIS for AS9100, AS9110, and AS9120 holders.
• — We have not verified SAM.gov headquarters of record for FEAM Aero, L2 Aviation, Safran Landing Systems Walton, Wheel & Brake Services LLC, HDT Expeditionary, AQW Inc, Desma USA, Mazak Corporation, Starrag USA, and any named Part 145 sub-vendors. Place-of-performance is not the same as the awardee's headquarters.
• — We have not pulled Kentucky DEP NPDES filings for the new DHL hangar — relevant for sizing ramp-tenant stormwater compliance work.
• — We have not enumerated the Cincinnati-side incumbent specialty subcontractor pool — Valence Surface Technologies, Metal Chem, the Cincinnati-area non-destructive testing and calibration shops. Which lanes those shops underprice on travel decides the local-capture thesis.

Tonight, this week, this month — in that order. Each step produces a yes/no or a number, not a deeper understanding.
