We discuss the most general form of the leading power suppressed collinear operators in the soft-collinear effective theory. Such operators appear in the description of power corrections to exclusive heavy flavor decays into energetic light hadrons. We consistently include the effects of three-particle light-cone distribution amplitudes and find that their impact could be of phenomenological relevance.
