What is a Pip-pin?
A pip-pin is another name for a ball lock pin. These are quick-release fasteners designed for secure installations and are easy for operators to use. In aircraft, pip-pins or ball lock pins are used in multiple areas, however the most visible application of ball lock pins in an aircraft is the arming/disarming mechanism of the aircraft doors.
