What is a HIMS Stepdown?

Stepdown is NOT guaranteed.

To enter the initial phase of HIMS Stepdown, the FAA, AME, and psychiatrist look for the pilot to embrace each element of the HIMS program, not only in the frequency of those targets, like attending a self-help group at least twice per week, but also with robust clinical evidence of a recovery process taking hold for the pilot.

You are more likely to enter Stepdown if you have a by-the-book program, with no variances at all.
