Built for Bonanza owners

Every annual, AD, gear check, and overhaul for your Bonanza, tracked in one place

Maggneto is the maintenance app for your Beechcraft Bonanza. Scan your logbooks in so your whole maintenance history lives in your pocket, searchable and easy to reference. Then set up tracking for the items that matter, the annual, recurring ADs, the landing-gear checks, the engine and prop overhaul, with custom intervals that count down from your real hours and dates.

The records that keep your Bonanza flying shouldn't live in a shoebox

The deadline you can't see is the one that gets you

Your records live in a binder, a shoebox of PDFs, and a few dates you're trusting yourself to remember. The annual, the transponder check, a recurring AD: any one of them can quietly slip past while you're busy flying, and you usually find out at the worst possible time.

A complex airplane has more to miss

A Bonanza is a high-performance retractable with a constant-speed prop and a longer list of recurring ADs than a simple trainer. More moving parts means more dates, and the expensive ones (the gear, the prop, the engine overhaul) all run on their own separate clocks.

The resale haircut

Bonanzas are prized and they hold their value, but only with complete, verifiable records. A documented airframe with a clean AD history sells. A murky one gets quietly discounted by buyers and their pre-buy mechanics.

How Maggneto works

  1. 1

    Scan your logbooks in

    Snap photos of your existing airframe, engine, and prop logs so your whole maintenance history lives in your pocket, searchable and easy to reference instead of buried in a binder or a folder of PDFs.

  2. 2

    Set up your tracking, your way

    Add the items you want to stay ahead of, from the annual to recurring ADs to the gear checks to the engine and prop overhauls, plus any custom items, each with intervals that fit your airplane. It's fully customizable, so you track exactly what matters for your tail number.

  3. 3

    Stay ahead, and keep the record

    Log a flight or an oil check in a few seconds and the countdowns update themselves. When you sell, you hand the buyer a clean, complete record that helps the airplane hold its value.

What a Beechcraft Bonanza owner tracks

These are the items most Bonanza owners have to stay on top of. Intervals vary by model, year, engine, and equipment, so treat these as typical and check them against your own aircraft's documents. For each one, here's how Maggneto keeps it from sneaking up on you.

Maggneto shows each item as:Up to dateDue soonOverdue

  1. 1.Annual inspection

    Every 12 calendar monthsCalendar

    Every certified Bonanza needs an annual inspection on a fixed calendar cycle, regardless of how many hours it flew that year.

    In Maggneto: Maggneto counts the annual down by date and shows a clear status (Up to date, Due soon, or Overdue) so you book the shop before the month runs out.

  2. 2.Airworthiness Directives & Service Bulletins

    Recurring, variesVaries

    Bonanzas carry recurring ADs, and the older V-tail (35-series) airframes in particular have directives tied to the tail and certain control surfaces. Which ones apply, and how often, depends on your model and serial number.

    In Maggneto: Maggneto tracks recurring ADs as scheduled items with a countdown and keeps a record of when each was last addressed, so a recurring one doesn't hide between annuals.

  3. 3.Retractable landing gear inspection & retraction check

    At annual, plus periodic serviceCalendar or condition

    The Bonanza's retractable gear needs recurring inspection, lubrication, and a retraction and rigging check. The gear motor and actuator are wear items, and a gear problem is both expensive and inconvenient.

    In Maggneto: Track the gear inspection and any gear service as recurring items so the airplane's most complex system gets eyes on it on schedule, not by surprise.

  4. 4.Oil & filter change

    Every 50 hours or 4 monthsHours or calendar

    Continental recommends oil and filter changes on a regular hours-or-calendar cycle, and oil is the cheapest, most honest read you'll get on engine health.

    In Maggneto: Maggneto counts the interval from your real tach time and turns your oil checks into a burn rate in quarts per hour, so a creeping consumption trend shows up long before it becomes a top-end problem.

  5. 5.Engine overhaul (TBO)

    ~1,700 hours or 12 years (typical)Hours or calendar

    The Continental engine in a Bonanza, whether an IO-470, IO-520, or IO-550, carries a published time between overhauls in both hours and years. It's the biggest single number on the airframe.

    In Maggneto: Maggneto tracks the engine on its own time with a progress bar toward TBO, so you can see the overhaul coming from years away and plan for it instead of getting surprised.

  6. 6.Propeller overhaul

    ~6 years or on hours (typical)Calendar or condition

    The constant-speed propeller carries its own overhaul interval in years and hours, separate from the engine, and it's easy to forget because it runs on a different clock.

    In Maggneto: Track the prop on its own schedule with a countdown, so the overhaul lands as a planned expense rather than a surprise at annual.

  7. 7.Magneto inspection

    Every 500 hours (typical)Hours

    Magnetos carry a recommended internal inspection on an hours cycle, and a tired magneto is a common cause of a rough run-up and a scrubbed trip.

    In Maggneto: Maggneto counts the magneto inspection down from your real engine hours alongside the rest of your recurring items.

  8. 8.Transponder, altimeter & pitot-static checks

    Every 24 calendar monthsCalendar

    The FAA requires transponder (91.413) and altimeter/static system (91.411) checks every two years for IFR flight, and most Bonanzas are flown IFR.

    In Maggneto: Maggneto tracks the 24-month checks as dated items so the certification never quietly lapses between annuals.

  9. 9.Vacuum system & gyros

    Condition, plus pump service lifeCondition

    If your Bonanza still runs vacuum-driven gyros, the dry vacuum pump has a service life and tends to fail without much warning, which is exactly when you don't want it to.

    In Maggneto: Track the vacuum pump age and gyro service as recurring items so an aging pump gets replaced on your terms.

  10. 10.ELT, batteries, brakes & tires

    Inspection and replacement on their own cyclesCalendar or condition

    The emergency locator transmitter needs periodic inspection and a battery on a fixed cycle, and the ship's battery, brakes, and tires are wear items that don't run on a clean clock.

    In Maggneto: Keep the ELT, batteries, and wear items on the schedule so the small stuff gets handled before it becomes a dispatch problem on a cold ramp.

These are some of the most common items a Bonanza owner tracks, not a complete list. Every airplane carries more depending on its equipment, avionics, modifications, and service history, and your mechanic and the aircraft's maintenance documents are the final word on what applies to your tail number. Maggneto lets you add and track as many custom items as your airplane needs.

The gear check and the prop overhaul you saw coming

It's spring and you open Maggneto before a trip. The annual is up to date, a recurring AD is on the calendar, the gear inspection is logged from the last annual, and the prop overhaul is still a year out but already on your radar with a countdown. After the flight you log the Hobbs and an oil check in under a minute, and the burn-rate trend updates itself. Nothing about your airplane is a mystery, and nothing sneaks up on you.

A Bonanza rewards an owner who stays ahead of it. Maggneto keeps every date and every hour in front of you, and turns your records into something worth real money when you sell.

Beechcraft Bonanza maintenance: common questions

How often does a Beechcraft Bonanza need an annual inspection?
Every certified Bonanza requires an annual inspection every 12 calendar months, regardless of how many hours it flew that year.
What is the TBO on a Bonanza engine?
The Continental engine in a Bonanza (IO-470, IO-520, or IO-550 depending on the model) typically carries a published time between overhauls of roughly 1,700 hours or 12 years, whichever comes first. Actual overhaul timing depends on the specific engine and how it is operated and monitored.
What are the recurring ADs on a Bonanza?
Bonanzas carry recurring Airworthiness Directives, and the older V-tail (35-series) airframes in particular have directives tied to the tail and certain control surfaces. Exactly which recurring ADs apply, and how often, depends on your model and serial number, so each one is best tracked on its own schedule.
How often does the Bonanza landing gear need service?
The retractable landing gear needs recurring inspection, lubrication, and a retraction and rigging check, typically at the annual and as specified in the maintenance manual. The gear motor and actuator are wear items that should be tracked over time.
What maintenance records do I need to sell a Bonanza?
Buyers and their pre-buy mechanics want complete, organized records: airframe, engine, and propeller logs, AD compliance including the recurring ones, landing-gear and prop overhaul history, and the most recent annual. Clean, searchable records protect a Bonanza's strong resale value; a disorganized record drags out the sale and lowers the price.
Can Maggneto track the ADs and gear checks for my Bonanza?
Yes. Maggneto tracks the annual, recurring ADs, the landing-gear inspection, oil changes, engine TBO, the propeller overhaul, magneto inspections, transponder and pitot-static checks, and your own custom items, each with a clear status and a countdown to the next due date.
