  The $B\rightarrow K_{2}^{\ast}(1430)l^{+}l^{-}$ $(l=\mu,\tau)$ decays are
analyzed in the Standard Model extended to fourth generation of quarks (SM4).
The decay rate, forward-backward asymmetry, lepton polarization asymmetries and
the helicity fractions of the final state $K^{*}_{2}(1430)$ meson are obtained
using the form factors calculated in the light cone sum rules (LCSR) approach.
We have utilized the constraints on different fourth generation parameters
obtained from the experimental information on $K$, $B$ and $D$ decays and from
the electroweak precision data to explore their impact on the $B\rightarrow
K_{2}^{\ast}(1430)l^{+}l^{-}$ decay. We find that the values of above mentioned
physical observables deviate deviate significantly from their minimal SM
predications. We also identify a number of correlations between various
observables in $B\rightarrow K_{2}^{\ast}(1430)l^{+}l^{-}$ and $B\rightarrow
K^{\ast}(892)l^{+}l^{-}$ decays. Therefore a combined analysis of these two
decays will compliment each other in the searches of SM4 effects in flavor
physics.
