Aircraft Pressurization Troubleshooting & Repair

Cabin Pressure Problems? We are On It.

We specialize in pinpointing pressurization issues and getting your jet back to flying smooth and safe. If your Citation’s pressurization system isn’t performing like it should, slow climbs, sudden altitude alerts, or that creeping pressure leak, come to us. 

We know the Citation 500 series inside and out, and that includes every seal, valve, and sensor in your pressurization system. If it is a subtle leak or a complete system fault, we get to the root fast and fix it right.

Pressurization Diagnostics: We Find the “Why” Fast

Cabin pressure issues aren’t always obvious, but their impact is serious. To find answers swiftly, we carefully inspect your system using cutting-edge diagnostics and in-person examination. We troubleshoot:

  • Cabin not holding pressure
  • Slow cabin climb or descent rates
  • Cabin altitude warning triggers
  • System leak detection
  • Outflow valve malfunctions
  • Pressure controller faults
  • Unusual noise or airflow during flight

Common Repairs We Handle

Once we isolate the fault, we fix it with precision. Every part we use meets or exceeds manufacturer’s specs. Every repair is signed off by Citation specialists. Our pressurization repair services include:

  • Outflow valve repair & replacement
  • Cabin pressure controller diagnostics & repair
  • Seal replacement (door seals, duct seals, cabin seals)
  • Altitude encoder calibration
  • Pneumatic line inspections and replacements
  • ECS (Environmental Control System) integration checks
  • System leak fixes and pressure testing
  • Cabin altitude warning system repairs

Our Process: Safe Cabin Pressure, Fast Turnaround

Step 1: You Report the Problem

Noticed the cabin not climbing with you? System alarms lighting up? We’ll talk through what you’re experiencing and schedule diagnostics ASAP.

Step 2: We Run a Full System Check

We get your jet into the hangar and start with a complete pressurization system review, valves, controllers, lines, sensors, and more. Leaks don’t hide from us.

Step 3: We Tell You What’s Really Going On

We don’t do sky-high estimates but give you a straight breakdown of the problem, the fix, the parts needed, and the timeline.

Step 4: We Get It Fixed, Fast

Once you approve the scope, we handle the repair with precision. Our team knows Citation systems cold, so we don’t waste time. You are back in the air faster.

Step 5: We Pressure-Test Before You Fly

Before your aircraft leaves our hangar, we perform full pressurization testing and performance validation. If it doesn’t pass with flying colors, it doesn’t leave.

People Also Ask

Most issues are caused by leaking seals, outflow valve malfunctions, pressure controller faults, or pneumatic leaks. Aging components or improper ECS balance can also contribute.

It depends on the issue. Minor seal replacements can be same-day; more complex faults like valve or controller issues may take 1–3 days with testing.

We use parts that meet or exceed OEM and FAA standards. Every repair is signed off by Citation-trained technicians.

No. Even small pressurization faults can lead to serious in-flight risks. FAA regulations require the system to be fully functional before flight.

Yes. Every pressurization repair includes full ground testing to ensure the system holds pressure throughout the flight envelope.
