S.01 · Annual inspection
The annual inspection is the once-a-year check every certificated aircraft needs to remain airworthy. We work to the FAR Part 43 Appendix D checklist, signed by an A&P with Inspection Authorization. You get a written squawk sheet, a plain-language logbook entry, and a phone call before we open anything we did not quote.
What is included: full airframe inspection, engine compression and oil filter cut, propeller hub and blade inspection, control surface and rigging check, landing gear and brake check, instrument and ELT test where applicable, AD compliance check against the FAA AD database, and a logbook entry that holds up to any subsequent IA reviewing your records. Squawk work is quoted separately and only authorized when you say yes.
S.02 · 100-hour inspection
If your aircraft carries persons or property for hire, or gives flight instruction for hire, FAR 91.409(b) requires a 100-hour inspection in addition to the annual. The checklist is functionally the same; the signoff difference is that any A&P can sign a 100-hour, while only an IA can sign an annual.
We run 100-hour inspections on aircraft in commercial service across the Florida Gulf Coast. Flight schools, charter operators, and rental fleets are all welcome. We schedule around your duty days, not the other way around. The full drop-off process stays the same; only the regulatory signature line differs.
S.03 · AOG mobile response
AOG service is the difference between flying home tonight and sleeping at a strange FBO. Our mobile vehicles are stocked for piston work and dispatched across the Florida Gulf Coast, with a stated response window that we hit. Call the AOG line any hour. Someone answers.
What we handle on a ramp call: dead battery, starter, alternator and electrical squawks, magneto issues, oil leaks, brake bleeds, tire changes, ignition timing, vacuum pump replacement, simple fuel system work, basic instrument swaps. What we will not do on a ramp call is sign off a finding that needs hangar time and a real teardown to verify. If your airplane needs more than a field repair we will get you ferry-permittable and home.
S.04 · Pre-buy inspection
A pre-buy is the most expensive cup of coffee you will ever skip, or the cheapest one you will ever buy. We perform independent pre-purchase inspections for buyers on aircraft anywhere on the Florida Gulf Coast. The report is written for the buyer and shared with the seller only if the buyer authorizes it.
What we look at: airframe condition, corrosion, compression test, oil filter cut, propeller and prop hub condition, landing gear and brakes, controls and rigging, avionics functional check, AD compliance status, logbook continuity and major repair history, paint and interior condition, and an estimate of near-term reserve maintenance you can expect to need in the first 100 hours.
S.05 · Robinson R44 service
Alpha Company Aviation is an authorized Robinson R44 Service Center. The shop is staffed and tooled around the R44 family. We schedule and coordinate the 12-year and 2,200-hour overhaul cycle. Inspections, scheduled components, dynamic balancing, and Safety Notice tracking are all in-house.
This catalog page summarizes the R44 work. The full breakdown lives on the dedicated R44 page, including a multi-view blueprint, sticky anatomy walk-through, lifecycle clock, and vibration signature visualization. Look us up under Service Centers at robinsonheli.com.
S.06 · Owner-assisted maintenance
Owner-assisted maintenance is one of the best traditions in general aviation. Under 14 CFR 43.3(d) the owner of an aircraft may perform maintenance under the direct supervision of a certificated mechanic, who then signs the work off. The owner saves money, learns the airplane, and gets to know the person signing the logbook.
We welcome owner-assist on annuals, oil changes, panel access, control rigging checks, brake bleeds, magneto timing, spark plug rotation, and most squawk work that does not require a special-purpose certification. Tell us at scheduling that you want to wrench. We block extra hangar time, set up tools, and slow the pace down so it is a real learning day.
S.07 · Piston powerplant
Most of our powerplant work is piston: Lycoming O-235, O-320, O-360, O-540, IO-540 and the equivalent Continental engines. Cylinder work, mag overhaul, ignition and fuel system, oil cooler, starter and alternator, prop strike inspection, intake and exhaust. Top overhauls are referred to a partner overhaul shop and reinstalled here.
Turboprop work shows up at the shop in the form of inspections, fluid changes, and minor squawk work. Hot-section and overhaul work is referred. Turbine work is referred. We do not sign turbine inspections we are not qualified to sign. The full engines section on the home page covers the scope at a glance.
S.08 · Confidential engagements
Aerial cinematography crews work under production NDA. Federal contractors flow privacy clauses down from their primes. Attorneys, physicians, and high-profile owners often prefer that maintenance and personal life stay separate. Repo and ferry operators work in time-sensitive silence by nature of the job.
Alpha Company Aviation is set up to handle quiet engagements without making a story of it. We sign mutual NDAs as a matter of course. We do not post customer aircraft on social media. We restrict hangar access and we are happy to invoice under a parent entity if you need that. Confidentiality covers identity and scope, not airworthiness. Write "discreet" in your work order and we pick up from there.
