What we handle on site

AOG work, done at your tiedown

Most of what strands a piston single or light twin is fixable on the ramp. Here's what we roll out for — and what we'll tell you straight away needs to come back to the hangar.

AOG-01

No-start & hot-start

Starter, solenoid, ignition switch, mags, fuel delivery, and induction. The single most common call we get — and usually the fastest fix.

AOG-02

Electrical & charging

Dead bus, alternator or regulator failure, battery, breakers, bonding, and wiring faults chased to the actual source rather than the easy guess.

AOG-03

Engine troubleshooting

Rough running, mag drop, fouled or failed plugs, injector cleaning, compression and borescope on the spot for Lycoming, Continental, and Rotax.

AOG-04

Tires, brakes & gear

Flat tire and tube changes, brake pads, worn discs, leaking calipers, gear rigging squawks, and shimmy — the stuff that grounds an otherwise healthy airplane.

AOG-05

Leaks & fluids

Oil, fuel, hydraulic and brake fluid leaks located and stopped. Hose, fitting, gasket, and seal replacement where the part is field-serviceable.

AOG-06

Ferry & recovery calls

When it isn't a ramp fix, we tell you fast, document it, and help you plan the recovery — trailer, ferry, or a tow back to T31 for hangar work.

Before you call

Five things that get us rolling faster

You don't need any of this to call — but if you have it ready, we can bring the right parts on the first trip instead of the second.

  1. Tail number, make & modelPlus engine type if you know it — 912 iS, IO-360, TSIO-550.
  2. Where the airplane sitsAirport identifier, FBO or row, and whether we can drive to it.
  3. What it didWhat you saw, heard, or smelled — and what the airplane was doing when it happened.
  4. Whether it's flyableDid you land it, taxi it, or has it not started at all?
  5. How hard the deadline isTrip tomorrow, checkride Friday, or "no rush" — it changes how we sequence you.

Response area

Where we roll

Dispatched from Aero Country (T31), McKinney. Rings are straight-line nautical miles from base — the fields below are the ones we're called to most. Outside 100 nm we still answer the phone — and we can often fly out to you — and we'll tell you honestly whether we're your fastest option or whether someone closer is.

The mobile shop

What shows up when you call

Not a mechanic with a toolbox in a truck bed. The van carries the tooling, test gear, and the consumables that fix most ramp squawks the same visit — plugs, filters, hoses, tubes, fluids, hardware, and the shop's diagnostic equipment.

Dispatch base

10020 Eagle Dr., McKinney

Aero Country Airport (T31). If the airplane can be flown or towed to us, hangar work starts here — and it's where the van rolls from at 2 a.m.

What to expect

Straight pricing, before we roll

You'll get a number on the phone before anyone gets in the van — the exact quote depends on your location, the aircraft, and the hour.

Every job is quoted before we roll. Call and we'll give you a straight number for your aircraft, your location, and the hour — no surprises.

No surprise invoices. Every finding gets photographed and priced before corrective work begins — same as our hangar policy. If we get there and it turns out to be a hangar job rather than a ramp fix, you pay the trip charge and the diagnostic, and we credit it toward the repair when the airplane comes to T31.

Aircraft broken down?

Stay calm. Call Mach first.

Any hour, any day. If you're standing on a ramp with a squawk and a schedule, that's exactly the call this line is for.
