The Partial-Wave analysis of the reaction: pi- Be -> pi-pi-pi+eta Be with E_beam = 28 GeV is performed in full 4-body mesonic final state phase-space. In the wide range of momentum transfer t' = 0.-1. GeV/c^2 the dominance of diffractive-like (natural-parity exchange) mechanism is demonstrated. The individual partial waves in f1(1285) pi-, eta'pi- and a2(1320) eta systems are discussed. There is no evidence of eta(1295) pi- production. Various interpretations of PWA results are suggested.
