The results of the Partial Wave Analysis of the reaction {pi}{sup -}p{yields}{eta}{pi}{sup +}{pi}{sup -}n are presented. The low-t sample is dominated by states, having OPE quantum numbers: 1{sup --},3{sup --},...,2{sup ++},4{sup ++},... . The most intensive wave is J{sup PC}=1{sup --}{rho}(770){eta}. The waves 3{sup --}{rho}(770){eta} and a{sub 2}(1320){pi} show the decay of {rho}{sub 3}(1690) meson, accompanied by further higher-mass resonances. The AX, f{sub 2}(1565), is observed decaying to [a{sub 2}(1320){pi}]{sub L=1}. In high-t sample the peak near 1.28 GeV consists of J{sup PC}=1{sup ++} and 0{sup -+} waves, while the peak near 1.40 GeV is completely 0{sup -+}.
