Fighter Aircraft Cabin Leakage Tester

The Aircraft Cabin Pressurization and Leakage Tester is a specialized ground support equipment (GSE) designed to assess the integrity of an aircraft's cabin pressurization system. Manufactured by Hydraulics International, Inc. (HII), this tester is essential for ensuring that both rotary and fixed-wing military and commercial aircraft maintain proper cabin pressure during operation. By simulating pressurization conditions, the tester identifies potential leaks or weaknesses in the cabin structure, thereby ensuring passenger safety and comfort.

Technical Details:

1. Flow Capacity:

   • The tester offers a flow rate of 400 Standard Cubic Feet per Minute (SCFM), providing sufficient airflow to pressurize various aircraft cabins effectively.​

2. Power Options:

   • Diesel Engine Driven: Part Number 93038-100 is equipped with a diesel engine, allowing for operation in environments where electrical power may be unavailable or unreliable.​

   • Electric Motor Driven: Part Number 96384-100 utilizes an electric motor, suitable for facilities with stable electrical infrastructures, offering quieter operation and reduced emissions.​

3. Compatibility:

   • The tester is qualified and in service with the United States Air Force (USAF), Navy (USN), and Marine Corps (USMC). It services a wide range of aircraft, including models such as the F-15, F-16, F-18, and C-130, among others.​

4. Design and Mobility:

   • Constructed with durability in mind, the tester is designed to withstand rigorous operational demands. Its mobility features enable easy transportation and positioning within maintenance facilities or on the flight line.​

5. Control and Monitoring:

   • Equipped with user-friendly controls and instrumentation, the tester allows maintenance personnel to monitor pressure levels accurately during testing procedures. This ensures precise detection of leaks and verification of cabin integrity.​

6. Safety Features:

   • Incorporates safety mechanisms to protect both the operator and the aircraft during testing. These features include pressure relief systems and emergency shutdown capabilities.​

Applications:

• Routine Maintenance: Regular use of the tester during scheduled maintenance ensures that the cabin pressurization system remains within operational specifications, preventing potential in-flight issues.​

• Post-Repair Verification: After structural repairs or modifications, the tester verifies that the cabin maintains proper pressurization, ensuring the integrity of the repair work.​

• Pre-Flight Checks: Utilizing the tester before flights, especially after extended periods on the ground, ensures that the cabin pressurization system is functioning correctly, contributing to passenger safety and comfort.​
