Bombardier has collaborated with the supplier of the Landing Gear Control Switches to improve their service life. As a result of this collaboration, an improved Landing Gear Control Switch P/N 7632608500-009 is now available.

The improved switches utilize more durable contact surfaces and improved activation springs that will result in longer service life. The improved switch is a direct replacement for currently installed switches. It will be listed in the Illustrated Parts Catalog (IPC) as an alternate for currently installed switches. Until the IPC is updated and published, a Reference Instruction Letter (RIL) will be published on the Customer Portal.
