The impregnation of aerogel by 3He provides a new opportunity to study the effects of disorder on the properties of liquid 3He. The transport coefficients exhibit cross-over behaviour from the high temperature regime, where inelastic 3He-3He scattering dominates,  to a low temperature regime dominated by elastic scattering of 3He off the aerogel. Within the homogenous scattering model,  analytical expressions for the thermal conductivity and viscosity can be derived and are shown in graphical form for 3He in aerogel.
