Product Description

The 45as39504-7 is a hydraulic down-lock release cylinder for retractable landing gear systems. This actuation component disengages the mechanical down-lock that holds the gear in the extended position, allowing controlled retraction during flight. The cylinder converts hydraulic pressure into linear motion to release the lock mechanism before gear movement begins.

Installed within the landing gear hydraulic circuit, it operates in coordination with main retraction actuators and control valves. Installation and rigging must follow aircraft maintenance manual specifications and approved technical data for your specific airframe.

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.
