Energy levels, line strengths, oscillator strengths, radiative decay rates and fine structure collision strengths are presented for sixteen-times ionized iron (Fe XVII). The atomic data are calculated with the AUTOSTRUCTURE code, where relativistic corrections are introduced according to the Breit-Pauli distorted wave approach. The calculations of atomic data for 89 fine-structure levels generated from eleven configurations 2s22p6, 2s22p5 (3s, 3p, 3d), 2s22p5 (4s, 4p, 4d, 4f) and 2s12p6 (3s, 3p, 3d) of the Ne-like Fe ion are presented. Fine structure collision strengths for transitions from the ground and the first four excited levels are presented at four electron energies: 75, 125, 175, and 250 Ry. These atomic structure data are compared with the available experimental and theoretical results.
