Product Description
The 979998-1 is a bleed-air manifold shutoff valve for turbine-powered aircraft pneumatic systems. This Honeywell Aerospace component isolates pressurized bleed air supply to the environmental control system, preventing unwanted airflow when the system is inactive. Commonly installed in Bombardier Challenger 601 and similar business jets, the valve integrates into the bleed-air manifold assembly.
Installation and functional testing must follow the aircraft maintenance manual and comply with FAA 14 CFR Part 43 requirements. Verify compatibility with the aircraft's illustrated parts catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
