Start a Business Aviation MRO (Maintenance Facility)

1. 1

   Define your MRO scope precisely

   MRO spans a wide range: line maintenance (routine servicing between flights), base and heavy maintenance (deep scheduled inspections and checks that take an aircraft out of service), avionics work, and type-specialized work. This card is the airframe-level facility, distinct from the component Part 145 repair station and the mobile line-maintenance service that already have their own cards in this library. Pick the scope and aircraft types your team can do impeccably before you build for more.

2. 2

   Secure hangar, tooling, and location

   Base and heavy maintenance needs hangar space, aircraft-specific tooling, ground support equipment, and a location near the operators and airports you will serve. This is the capital core of the business. Choose an airport with the traffic, based-aircraft population, and operator presence to keep the hangar utilized, because an empty maintenance hangar carries cost whether or not aircraft are in it.

3. 3

   Earn repair-station approval and certifications

   Serious MRO work runs under FAA repair-station approval (Part 145) with the ratings for the work you perform, plus certified technicians (A&P mechanics, inspection authorization where required, and manufacturer or type training). The approval and certification process is a real timeline and cost. Build your certified team and your approvals to match your defined scope, not a wishlist.

4. 4

   Build parts sourcing and AOG response

   Maintenance depends on parts (see the aviation parts distribution card in this library) and on responding fast to aircraft-on-ground situations, which are urgent and high-value. Establish parts sourcing relationships and a plan for AOG turnarounds, because an operator whose aircraft you recover quickly becomes a loyal account. Reliability and speed are worth more to operators than the lowest labor rate.

5. 5

   Land the accounts that keep the hangar full

   Your buyers are charter operators, aircraft management companies, corporate flight departments, and owners, all of whom need reliable maintenance capacity. Standing maintenance agreements and being the shop operators trust for scheduled and AOG work are what create predictable revenue. Utilization is the whole game: a busy hangar at a fair rate beats an idle one holding out for a premium.

6. 6

   Run on safety, records, and labor-rate discipline

   MRO revenue is driven by billable labor hours at your shop rate plus parts, so technician utilization, honest labor estimating, and airtight maintenance records (which carry airworthiness and liability) decide both profit and reputation. One records or airworthiness failure damages the shop's standing with every operator. Build quality systems and record discipline as the foundation, then grow scope as your certified capacity allows.

Best for: Experienced aircraft maintenance leaders (DOMs, A&P/IA technicians) ready to own the shop

Not for: Anyone without deep aircraft-maintenance leadership or the capital for a hangar, tooling, and certifications. This is a facility business built on approvals, records, and utilization, not a light-touch service.
