Nav-Aids PSS73260-3-4-4 Pitot & Dual Static Test Adapter – Select Bombardier Aircraft

The Nav-Aids PSS73260-3-4-4 is a pitot and dual static test adapter designed for pitot-static system testing on a wide range of Bombardier business jet aircraft. It interfaces directly with the aircraft's pitot and dual static probes, allowing technicians to connect an air data test set and verify the integrity of the air data system. The adapter is engineered for reliability and safety, featuring AN fittings, built-in safety compartments, and a "Remove Before Flight" tag as standard.

The PSS73260-3-4-4 is compatible with a wide range of Bombardier aircraft, including the Challenger 300, Challenger 350, and BD100, as well as the Global Express and Global 5000, 5500, 6000, and 6500. It is also compatible with the Bombardier Challenger CL600, CL601, CL604, and CL605 aircraft. This broad platform coverage makes the PSS73260-3-4-4 a versatile tool for MRO shops and flight departments maintaining multiple Bombardier airframes.

The PSS73260-3-4-4 fits two different probe configurations depending on the aircraft. On the Challenger 300, Challenger 350, and BD100, it interfaces with the 0856WC pitot and dual static probes located on the nose, while on the Global Express and Global 5000, 5500, 6000, and 6500, it is designed for the 856TT 2, 3, and 4 probes, also nose-mounted. Always confirm the probe part number on your specific aircraft before installation to ensure proper fit and sealing.

Yes. Once installed, the PSS73260-3-4-4 allows each system to be isolated and tested separately or simultaneously, depending on the test procedure. This flexibility supports both full air data system certification – where all channels are tested together – and targeted fault-isolation testing, where a specific system needs to be checked without disturbing the others. The dual-mode capability makes this adapter well-suited for both scheduled maintenance events and unscheduled troubleshooting.

The quantity required varies by aircraft type. Two adapters are needed per Challenger 300, Challenger 350, or BD100 aircraft, while four are required per Global Express or Global 5000, 5500, 6000, or 6500 aircraft – reflecting the greater number of probe locations on the larger Global platform. Maintenance teams should ensure the correct quantity is on hand and all adapters are in serviceable condition before scheduling a test event.

The PSS73260-3-4-4 includes several notable safety features designed to protect both the aircraft and the test equipment. Safety compartments are built directly into the adapter to protect the air data system in the event the unit is improperly installed – a particularly important safeguard on the complex probe configurations found on the Bombardier Global series. A "Remove Before Flight" tag is also included as standard, providing a clear visual reminder to remove the adapter before the aircraft returns to service.

The protective caps included with the PSS73260-3-4-4 serve a dual purpose – they protect the adapter's internal seals and fittings during storage, and they can also be used as pre-test probes to verify the integrity of the adapter and hose assemblies before connecting to the aircraft. Using the caps as pre-test probes allows technicians to confirm the test circuit is leak-free without exposing the aircraft's air data system probes – an important step in ensuring accurate test results and avoiding potential damage to the ADSP. This built-in functionality eliminates the need for a separate pre-test probe component.

The PSS73260-3-4-4 is compatible with any standard air data test set, thanks to its AN fitting connections – a widely used, reliable fitting standard across aviation ground support equipment. This open compatibility gives maintenance teams the flexibility to use the adapter with the pitot-static test unit already in their GSE inventory, rather than being locked into a specific tester brand or model. Always confirm hose assembly compatibility with your specific test set before beginning a test sequence.

Yes. While the PSS73260-3-4-4 is available individually, it is also included in several Nav-Aids air data accessories kits. The BD100-945 Air Data Accessories Kit covers the Challenger 300, Challenger 350, and BD100, while the ADGE95-612 Air Data Accessories Kit is designed for the Global Express and Global 5000, 5500, 6000, and 6500. For shops maintaining a broader mix of Bombardier airframes, the BAC-945 Air Data Accessories Combination Kit extends coverage to include the CL600, CL601, CL604, and CL605 as well.
