Description of Tool Usage:

This tool is used to hold open a thrust reverser during an engine change. The A78001-21 is used on powered-open actuators on CF6-80A engines. The A78001 can be used in conjunction with the G78005 thrust reverser hold open rod adapter. G78005 is a sleeve-like tool that is used to extend the effective length of the thrust reverser hold open rod. The G78005 allows for more room for the A78001 thrust reverser equipment to be safely attached to the thrust reverser actuator. The A78001 equipment is not to be used if wind speed exceeds 40 knots.
