This specification defines the requirements for a threaded rigid coupling assembly, which utilizes ferrule type machined tube end fittings, to join tubing and components in aircraft fuel, vent, and other systems. This coupling assembly is designed for use from -65 to 200 °F and at 125 psig operating pressure.
Rationale:
This revision clarifies test schedules and sequences, adjusts bending strain based on a modulus of 9.9 x 106, and reduces total flexure cycles from 10 000 000 to 1 000 000.
