The cross section and analyzing power of the {rvec p}p{r_arrow}pn{pi}{sup +} reaction near threshold are estimated in terms of data obtained from the {rvec p}p{r_arrow}d{pi}{sup +} and pp{r_arrow}pp{pi}{sup 0} reactions. A simple final state interaction theory is developed which depends weakly upon the form of the pion-production operator and includes some Coulomb corrections. Within the uncertainties of the model and the input data, the approach reproduces well the measured energy dependence of the total cross section and the proton analyzing power at a fixed pion center-of-mass angle of 90{degree}, from threshold to T{sub p}=330 MeV. The variation of the differential cross section with pion angle is also very encouraging. {copyright} {ital 1997} {ital The American Physical Society}
