Abstract: 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).

Abstract: A deicer is provided for breaking up and removing accumulated ice on an airfoil surface. The deicer includes a bondside surface that is bonded to the airfoil surface, a breezeside surface on which the ice will accumulate, and passage-defining surfaces therebetween. The passage-defining surfaces define a plurality of expansible and contractible inflation passages and include a moisture-impervious coating whereby moisture within the inflation passages will not be absorbed by the surfaces. The bondside, breezeside and passage-defining surfaces may be contained on a deicer panel and means may be provided for introducing inflation fluid to and evacuating inflation fluid from the passages to expand and contract the inflation passages to break up and remove the accumulated ice.
