A period of disability ends with the earliest of:
- The last day of the 2nd month after the month in which medical recovery occurs.
- The date determined by the RRB if you are doing or have done "substantial gainful work" since your period of disability began (see Trial Work Period).
- The last day of the month before the month full retirement age is attained.
- The last day of the month in which your death occurs.
The special ending date rules for cases involving substantial gainful work are not covered in this booklet due to their complexity. If you have any questions about them, contact the nearest field office of the RRB.
