No one budgets for a toilet. Until the toilet breaks.
And suddenly, a $20,000 lav is the only thing standing between you and another grounded B737 Max.
Here’s the truth:
You can do everything right—pre-buy programs, provisioning plans, predictive analytics—and still get taken down by a part that no one talks about until the cabin crew files the write-up.
The Part That Grounds Aircraft (and It’s Not What You Think)
We’re not talking about engines, brakes, or avionics.
We’re talking about the 4100387-003-03 toilet unit for the 737 Max.
When this lav fails:
Ops has to pull the aircraft.
You burn crew hours and lose rotation slots.
PAX get rebooked, reimbursed, and angry.
Your planner’s phone won’t stop buzzing.
All because of a toilet that nobody had on hand.
The Fix That’s Actually on the Shelf
We’ve got one.
It’s overhauled, dual release, tagged for 2025, and it’s ready to ship.

This isn’t some placeholder listing.
It’s in our facility, boxed, and can be moving to your dock before your MEL time expires.
Stop Thinking of Lavs as Low Priority
Want the ugly truth?
High-failure, low-stock cabin parts are the reason some operations are burning margins on “minor” maintenance delays.
Toilets, seat actuators, faucets—they don’t feel like flight-critical components until the delay report hits your desk.
And by then?
Lead times are 30+ days.
The quote loop is chaos.
You’re paying triple just to get it AOG.
Fix It Before It Breaks
This lav is a smart buy—not just because it’s OH and available—but because it eliminates a hidden risk in your fleet readiness.
This is what proactive provisioning looks like.
Not waiting for the next failure.
Buying smart before it costs you six figures in downtime.
Want It?
You don’t need more parts.
You need the right ones, ready now, with zero excuses.
Let’s fix that.
