  We have constructed a specific supersymmetric flipped SU(5) GUT model in
which bilarge neutrino mixing is incorporated. Because the up-type and
down-type quarks in the model are flipped in the representations ten and five
with respect to the usual SU(5), the radiatively generated flavor mixing in
squark mass matrices due to the large neutrino mixing has a pattern different
from those in the conventional SU(5) and SO(10) supersymmetric GUTs. This leads
to phenomenological consequences quite different from SU(5) or SO(10)
supersymmetric GUT models. That is, it has almost no impact on B physics. On
the contrary, the model has effects in top and charm physics as well as lepton
physics. In particular, it gives promising prediction on the mass difference,
$\Delta M_D$, of the $D-{\bar D}$ mixing which for some ranges of the parameter
space with large $\tan\beta$ can be at the order of $10^9 ~\hbar ~s^{-1}$, one
order of magnitude smaller than the experimental upper bound. In some regions
of the parameter space $\Delta M_D$ can saturate the present bound. For these
ranges of parameter space, $t \to u,c+h^0$ can reach $10^{-5}-10^{-6}$ which
would be observed at the LHC and future $\gamma-\gamma$ colliders.
