FAA Flags 3D-Printed Cockpit Accessories: Why a Cup Holder Becomes an Airworthiness Question

The FAA issued Unapproved Parts Notification 2026-AAE-EHL-20250507-177 on August 18, 2026, covering 3D-printed cockpit and interior accessories produced and sold by Michael Graham, doing business as MadeByMike3D. According to the agency, the articles were made and sold between May 2024 and August 2025 for installation on type-certificated aircraft — including Beechcraft Bonanza and Debonair, Grumman AA1 and AA5, and Cirrus — without FAA approval or authorization. The items are cup holders, yoke grips, headset holders, windshield shades, defroster vent components, a microphone caddy, and similar accessories. No engine, propeller, structural, or aerodynamic components are involved, and the FAA has not reported any failure or incident associated with the parts. The agency recommends owners and maintenance organizations inspect aircraft and inventories, quarantine any parts found in stock, and report anything already installed pending an eligibility determination.

A 3D-printed cup holder doesn’t change how an airplane flies. But it does change whether the aircraft still conforms to its approved design — and that question follows the airplane through every future annual and every future pre-buy.

What the Notification Covers

The FAA’s table lists articles by nomenclature and applicable aircraft. The items identified include:

Note that the list also includes items intended for simulators, which are not type-certificated aircraft — a detail worth keeping straight when checking your own inventory.

Why the FAA Flagged Them

The FAA identified the articles through three indicators, according to the notification:

Active Etsy listings advertising the parts for aircraft installation.

No evidence of production by an FAA-approved manufacturer — meaning no Parts Manufacturer Approval (PMA) or equivalent authorization.

Missing markings required under 14 CFR 45.15, the regulation governing how approved parts must be identified.

Under FAA rules, articles produced for sale as replacement or modification parts for type-certificated aircraft generally require a Parts Manufacturer Approval. The critical phrase is “for sale.” That’s the line these articles crossed — not their function, but their commercial production and distribution without the approval the regulations require.

The Conformity Problem

Here’s why this matters more than the items themselves suggest.

An aircraft holds an airworthiness certificate on the condition that it conforms to its type design. Anything installed that isn’t part of that design, or approved as an alteration to it, is a deviation — regardless of whether it’s a wing spar or a cup holder.

The consequences aren’t dramatic. They’re cumulative and administrative:

At annual inspection. An IA signing off an annual is attesting the aircraft is in airworthy condition. An inspector who finds an undocumented, unapproved part has a problem to resolve — and how easily it resolves depends on documentation that may not exist.

At pre-buy. This is where it bites hardest. A pre-buy inspection is a buyer’s mechanic looking for exactly this kind of discrepancy. An unapproved part with no paperwork becomes a negotiating point at best and a deal complication at worst, and the buyer’s mechanic has no obligation to be generous about it.

In the logbooks, permanently. Aircraft records follow the airframe forever. A conformity question raised once tends to resurface at every subsequent transaction.

Cumulatively. Conformity issues rarely start with a dramatic modification. They accumulate — a bracket here, an accessory there, each individually trivial, collectively a records problem the current owner didn’t create and can’t easily unwind.

That’s the real lesson: the same documentation discipline applied to avionics and systems belongs on interior and cockpit additions too.

The Owner-Produced Parts Nuance

There’s a legitimate wrinkle worth understanding, and it’s the source of much of the community pushback this notification has generated.

FAA rules do include provisions for owner-produced parts — parts an aircraft owner produces for their own aircraft under specific conditions, without PMA. That’s why a pilot who 3D-prints a cup holder for their own airplane sits in a materially different position from someone selling the same item on Etsy to strangers.

There are also questions around what constitutes a minor alteration versus a major one, and around items that are removable and non-structural. Reasonable people in the maintenance community disagree about where exactly the line falls for a suction-cup-mounted accessory.

None of that changes what the notification actually says. The FAA’s concern is the commercial production and sale of articles for installation on type-certificated aircraft without approval — not whether a cup holder is dangerous. And the practical advice for owners is unaffected by the philosophical debate: if an unapproved part is installed on your aircraft, the question of its eligibility is now on the record, and resolving it is easier before an inspector or a buyer’s mechanic raises it.

It’s also worth noting what the FAA did not say. There is no airworthiness directive here. No aircraft is grounded. No failure has been reported. A UPN is a notification and a recommendation, not a mandate — but ignoring it doesn’t make the conformity question go away.

What Owners Should Do

If you own a Bonanza, Debonair, Grumman AA1 or AA5, or a Cirrus — or you bought aviation accessories online in the past two years:

Inspect the aircraft. Look at the cockpit and interior for accessories you didn’t install or can’t account for. Cup holders, yoke grips, headset hooks, and vent extenders are the categories in question.

Check your inventory. If you have any of these articles in a parts stock or hangar shelf, the FAA recommends quarantining them so they aren’t installed pending an eligibility determination.

Talk to your mechanic before removing anything. Your A&P or IA is the right person to assess what’s installed and how to document its removal or its eligibility. Pulling a part yourself without a record can create its own paperwork gap.

Review the logbooks. Check whether any accessory installations were logged, and how. Documented minor alterations are a very different situation from undocumented ones.

Report installed parts as the notification recommends, pending the FAA’s determination of eligibility.

Apply the lesson going forward. Before buying any part or accessory advertised for aircraft installation, ask the basic question the FAA is pointing at: was this produced under an approved process, and can the seller show it? For a $40 accessory, that’s an easy question to skip. It’s also the question that shows up years later at pre-buy.

The Bottom Line

The FAA’s notification on MadeByMike3D articles isn’t about dangerous parts. It’s about approval status and documentation — and the fact that an aircraft’s conformity to its type design is a permanent, cumulative record that outlives any individual owner.

For Bonanza, Debonair, Grumman, and Cirrus owners, the immediate action is straightforward: check the airplane, quarantine anything in inventory, talk to your mechanic, and report what’s installed.

For everyone else, the broader point is the durable one. Minor cockpit accessories are exactly where documentation discipline slips, because the items seem too small to matter. The airplane’s records disagree — and they’re the ones a buyer’s mechanic will be reading.

Frequently Asked Questions

What did the FAA’s MadeByMike3D unapproved parts notification say? The FAA issued Unapproved Parts Notification 2026-AAE-EHL-20250507-177 on August 18, 2026, covering 3D-printed cockpit and interior accessories produced and sold by Michael Graham, doing business as MadeByMike3D, between May 2024 and August 2025. The agency states the articles were sold for installation on type-certificated aircraft without FAA approval or authorization, and recommends that owners and maintenance organizations inspect aircraft and inventories, quarantine any articles found in stock, and report parts already installed pending an eligibility determination.

Which aircraft and parts are affected? The notification lists cup holders, yoke grips and yoke pad covers, headset holders and hooks, defroster vent extenders and hood defrost vents, a microphone slot caddy armrest, a battery box cover, and a raised emblem, applicable to Beechcraft Bonanza and Debonair, Grumman AA1 and AA5, and Cirrus aircraft. Some listed items were intended for Cessna 150 and Grumman AA5 simulators, which are not type-certificated aircraft.

Are these parts dangerous? The FAA has not reported that any of the listed articles failed or caused an incident, and the notification does not identify any engine, propeller, structural, or aerodynamic components. The concern is regulatory rather than functional: articles produced for sale as replacement or modification parts for type-certificated aircraft generally require a Parts Manufacturer Approval, and the FAA cited the absence of evidence of approved production along with missing markings required under 14 CFR 45.15.

Why does an unapproved cup holder matter if it doesn’t affect flight? An aircraft’s airworthiness certificate depends on conformity to its approved type design. Anything installed outside that design, or not approved as an alteration to it, is a deviation regardless of function. The practical consequences appear at annual inspections, where an IA must resolve undocumented parts, and especially at pre-buy inspections, where a buyer’s mechanic will flag them. Because aircraft records follow the airframe permanently, a conformity question raised once tends to resurface at every subsequent transaction.

Can I make parts for my own airplane? FAA rules include provisions for owner-produced parts under specific conditions, which is a materially different situation from producing articles commercially for sale to others — the activity the notification addresses. Questions around what qualifies as a minor alteration and how removable, non-structural accessories are treated are genuinely debated within the maintenance community. Owners should consult their A&P or IA about any specific part, both for eligibility and for proper logbook documentation.
