The A35001-13 Firing Pin Retraction Equipment is specialized aircraft maintenance tooling designed for retracting the firing pin of chemical oxygen generators during aircraft oxygen system maintenance. Aviation tooling references identify it as “Equipment – Firing Pin Retraction, Oxygen Generators”, and Boeing maintenance documentation lists A35001-13 as an optional tool for oxygen generator firing-pin retraction and safety-pin installation procedures.

The tool is used to support controlled servicing of chemical passenger oxygen generator assemblies, helping maintenance personnel safely manage the firing mechanism during inspection, maintenance, and related servicing operations. It is applicable across multiple Boeing aircraft, including 737, 747, 757, 767, and 777 series aircraft.
