Recently the LIGO and VIRGO Collaborations reported observation of gravitational-wave signal corresponding to inspiral merger two black holes, resulting into formation final hole. It was shown that observations are consistent with Einstein theory gravity high accuracy, limited mainly by statistical error. Angular momentum mass hole were determined rather large allowance tens percents. Here we shall show this indeterminacy in range black-hole parameters allows for some non-negligible deformations Kerr spacetime leading same frequencies ringing. This means at current precision experiment there remains possibility alternative theories gravity.
