Aircraft drainmast assembly

摘要

A drainmast assembly ( 10 ) for ejecting gray water from the onboard potable water system of an aircraft. The assembly ( 10 ) includes an interface ( 14 ) mounted on the fuselage of the aircraft and a drainmast ( 16 ) including a fairing ( 90 ) aligned with and attached to the interface ( 14 ). The interface ( 14 ) includes a pipe ( 46 ) having an outlet nipple ( 48 ) which is pivotally connected to an inlet portion ( 146 ) of the draintube ( 94 ). In this manner, the draintube ( 94 ) can rotate relative to the interface ( 14 ) should the fairing ( 90 ) be unintentionally hit by a baggage vehicle and shoved out of alignment with the interface ( 14 ).
