We present the solutions of the Einstein-Dirac equations in a Bianchi type-I space-time
with cosmological constant 
. According to the value of a dimensionless parameter 
, three
classes
of solutions of the Einstein-Dirac equations exist. If 
, these solutions have two singularities
t1 and
t2: as 
the metric tensor is of Kasner type, whereas, as 
, it
becomes isotropic and, because of , has a stationary-type behaviour.
