The pionic decay rates of the excited L = 0, 1 D mesons are calculated with a Hamiltonian model within the framework of the covariant Blankenbecler-Sugar equation. The interaction between the light quark and charm antiquark is described by a linear scalar confining and a screened one-gluon exchange
