Beechcraft built it to last 60 years. Maintained right, it will.
A Bonanza or Debonair is a different animal from a modern composite single — an heirloom airframe, often older than the pilot flying it, built to a standard that rewards an owner who looks after it. Mach Aircraft Maintenance keeps the Model 33, the V-tail 35, and the Model 36 honest across DFW and North Texas: the recurring spar inspection, the magnesium, the gear, the fuel cells, and the Continental up front. Every finding goes in writing, with a price, before a wrench turns.

We are not a Textron Aviation factory service center — and for a 40- or 60-year-old Bonanza, that hardly matters, because these airframes left warranty decades ago. What a legacy Beech actually needs is a mechanic who knows its quirks cold: where the magnesium corrodes, how the retract gear rigs, which revision of the spar AD applies to your serial number, and how to track down the right part for an airplane the factory no longer rolls off the line. We are FAA-certificated A&P mechanics who have spent real hours inside these empennages, we keep current with American Bonanza Society service knowledge, and under 14 CFR Part 43 any A&P can inspect, maintain, and return your Bonanza or Debonair to service.
What we do for Bonanza & Debonair owners
We know where these airframes hide trouble
Bonanza & Debonair annuals
Full annuals worked to the Beechcraft maintenance manual for the Model 33 (Debonair / Bonanza 33), the V-tail Model 35, and the Model 36 / A36 — with AD and Service Bulletin research, a photographed squawk list, and pricing before any corrective work.
Continental engine work
Service and troubleshooting for the Continental engines that power these airframes — the IO-470, IO-520, and IO-550, including IO-520-to-IO-550 conversions — with compression and borescope, oil analysis, induction, exhaust, and baffling.
V-tail ruddervators & spar
The Model 35 needs a careful, knowing eye: ruddervator skin and balance, magnesium corrosion, hinge and bracket condition, and the recurring forward-spar carry-through inspection under AD 94-20-04. We know where these airframes hide trouble.
Retractable landing gear
Gear swings, rigging, and the wear items the Bonanza gear is known for — gear motor and actuator, no-back spring, downlock springs, rod ends, and the rigging that keeps the gear locking down and the doors timed right.
Fuel cells & fuel system
Aging Bonanza fuel bladders crack and seep. We replace fuel cells, chase leaks and weeping fittings, and service tank selectors, sumps, and senders so your fuel system is dry, accurate, and trustworthy.
Magnetos & propellers
The recurring 500-hour magneto inspection and timing, harness and plug service, plus Hartzell / McCauley propeller removal, AD/SB compliance, and dynamic balancing to take the buzz out of the airframe.

Why Beechcraft owners choose Mach
These airplanes were over-built to begin with, and they reward an owner who looks after them with intention. We go through the spar, the gear, the magnesium, and the fuel system the way someone who plans to fly the airplane for the next thousand hours would — methodically, with an eye on its long-term health, so the small findings get caught while they are still small and cheap.
Findings come with photographs and a price before we touch them, and the logbooks go back clean and legible — the kind of paper trail that protects the airplane's value for the next owner. Work happens at our Aero Country (T31) hangar, and if a Bonanza goes down on a ramp somewhere, the AOG line is answered around the clock.
Shopping for a Bonanza? Have an independent shop in your corner before you sign. A pre-buy is the one inspection you commission for yourself — a full logbook and records audit, research on the applicable V-tail spar AD, an airframe and engine evaluation, a compression and borescope of the Continental, and a hard look at the gear, the magnesium, and the fuel cells. You come away with a candid written report, photos, and a realistic cost-to-cure on every finding, so you sign with confidence — knowing exactly what you are buying and what it will cost to keep flying. Looking at a Model 33, 35, or 36? Send the tail number and we'll set up the pre-buy.
Beechcraft owner questions
Which Beechcraft models do you work on?
The Continental-powered Bonanza and Debonair line — the Model 33 (Debonair, Bonanza 33, and the A33/C33/E33/F33A), the straight-tail and V-tail Model 35, and the stretched Model 36 / A36. Whether your engine is an IO-470, IO-520, or IO-550, we service it.
Do you inspect the V-tail spar and AD 94-20-04?
Yes. The V-tail Model 35 has a recurring forward-spar carry-through (the “bathtub fitting”) inspection under AD 94-20-04, plus ruddervator skin, balance, and magnesium-corrosion items unique to the tail. We research the applicable revision for your serial number, perform the inspection, and document it correctly in the logbooks.
Are you a Beechcraft authorized service center?
No — Mach is an independent A&P maintenance shop, not a Textron Aviation / Beechcraft authorized service center. You do not need an authorized center for Bonanza and Debonair maintenance: under 14 CFR Part 43, any certificated A&P can inspect, maintain, and return these aircraft to service. For annuals, engine and gear work, fuel cells, the V-tail spar AD, and routine care, we have deep hands-on Beechcraft experience and give you honest, owner-first service.
Can you rig the landing gear and do a gear swing?
Yes. We swing and rig the retractable gear, service the gear motor and actuator, replace worn rod ends, no-back and downlock springs, and time the gear doors — the work that keeps a Bonanza locking down reliably and passes a clean annual.
Can you still get parts for an out-of-production Beechcraft?
Yes. Textron still supports much of the line, and between factory channels, the strong Bonanza and Debonair parts aftermarket, PMA parts, and American Bonanza Society resources, we source what these airframes need. When a part is the long pole in a repair — a fuel cell, a gear component, a tail part — we tell you up front so you can plan the downtime around it instead of being surprised by it.
Should I bring the airplane to you, or do you come out?
We are based at Aero Country Airport (T31) in McKinney and serve Bonanza and Debonair owners across DFW and North Texas — McKinney, Frisco, Allen, Plano, Prosper, Denton, Sherman, and Greenville. The deeper Beech work — annuals, the spar inspection, gear rigging, and fuel cells — is best done in our equipped hangar, so for those we would rather you fly it in. Routine squawks and AOG troubleshooting we can handle mobile at your hangar.
