The AA716 is a specialized aircraft vacuum pump wrench designed for installation and removal of aviation engine-driven vacuum pumps during aircraft maintenance procedures.

This tool is engineered specifically for use with Tempest and compatible aircraft vacuum pump assemblies, allowing technicians to safely apply torque in confined engine compartment spaces without damaging pump fittings or housings.

Key features include:

Purpose-built aviation vacuum pump service wrench
Designed for installation and removal of aircraft vacuum pumps
Heavy-duty steel construction
Precision-fit engagement for secure grip
Corrosion-resistant finish
Allows controlled torque application
Designed for confined aircraft engine bay access
Compatible with Tempest and similar aviation vacuum pump systems
Suitable for maintenance, overhaul, and field servicing
The AA716 is commonly used by aircraft maintenance technicians, A&P mechanics, and overhaul facilities for servicing engine-driven vacuum systems in general aviation aircraft where proper tool fit is critical to prevent component damage.
