An improved air scoop lip warmer de-icing system for an aircraft having at least one internal combustion engine mounted thereon for powering of said aircraft and having an elongated air scoop mounted thereto with a forwardly open end facing the air stream passing over the aircraft for operatively feeding air to the engine from the air scoop to effect a combustible mixture with engine fuel, and wherein said engine includes an exhaust pipe system for exhausting hot exhaust gases, said system comprising: a tubular metal loop configured to the open end of said air scoop, mounted to the interior of said air scoop adjacent said open end at the edge thereof, said tubular metal loop comprising a complete loop of relatively small diameter metal tubing, an inlet tube integral with said loop, extending away from said open end of said air scoop and within said air scoop, a hose clamped at one end to said inlet tube and at the other end to said exhaust pipe of said engine, an outlet tube integral with said loop at a point within said loop remote from said inlet tube, said outlet tube extending away from the open end of said air scoop and projecting through said air scoop wall rearwardly of the air scoop opening with said outlet tube open to the aircraft exterior on the surface of the elongate air scoop remote from the open end thereof, such that the exhaust gases bled from said exhaust pipe feeds to the loop through said inlet tube, divides at the intersection of said inlet tube and said loop, transverses portions of said loop as a split flow and joined at the connection of said outlet tube of said loop for common exhaust to the aircraft exterior.
