Dear Mr. Ferguson: This is in reply to your letter of September 28, 1972, concerning th application of Motor Vehicle Safety Standard No. 302, 'Flammability of Interior Materials', to the plastic air discharge chambers or combination air chamber-unit housings of the air-conditioning units you manufacture for use in motor vehicles. You ask whether this equipment must meet the requirements of the standard.; The portion of an item of a motor vehicle equipment that forms part o a component listed in the standard will normally be subject to the standard. From the photographs of your equipment that you submitted, we would consider an air discharge chamber or combination air chamber-unit housing that forms part of the surface of a front or side panel to be incorporated into the panel and therefore subject to the standard. The air discharge chamber or combination chamber-unit housing of your roof-mounted equipment is not a part of the 'headlining,' and accordingly would not be subject to the standard.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
