We present model independent measurements of the helicity basis form factors in the decay D+ -> K- pi+ e+ nu_e obtained from about 2800 decays reconstructed from a 281 pb^{-1} data sample collected at the psi(3770) center-of-mass energy with the CLEO-c detector. We confirm the existence of a previously observed …
