Starting from the edge reconstructed Pfaffian state and the anti-Pfaffianstate for the filling fraction $\nu={5/2}$ fractional quantum Hall (FQH) statewith the filled Landau levels included, we find that interactions betweencounterpropagating edge modes can induce phase transitions on the edge. In thenew `Majorana-gapped' phases, a pair of counter propagating neutral Majoranamodes becomes gapped. The quasiparticle tunneling exponent changes from $g=1/4$to $g=1/2$ for the edge reconstructed Pfaffian state, and changes from $g=1/2$to $g=0.55-0.75$ for the anti-Pfaffian state, in the new Majorana-gappedphases. The new phases are candidate states for the observed $\nu={5/2}$ state.Furthermore, Majorana-gapped phases provide examples that non-trivial quantumphase transitions can happen on the edge of a FQH state without any change inbulk topological order.
