A combined V light curve of a recently discovered bright massive close eclipsing binary system HD 167971 has been analyzed by Wilson-Dewinney code. Because of a very Iow amplitu- de variation in light, no unique solution for the physical and geometrical elements could be obta- ined. However, evidences are found that the contact or almost contact component stars have comparable masses around 50 Mo each, and the inclination of the orbit is about 65°. There may be a third component star in the system.
