ANSWER: Yes. Although you will lose your disability retirement annuity if you are "restored to earning capacity," you may reapply. On reapplication, you will have to demonstrate not only that your earnings have diminished for an entire calendar year below the 80% ceiling, but also that you are still disabled from your old government job (and not some other job) by the same disability (and not some other disability) that disabled you before. This can be very tricky. The best advice: make sure that you keep your earnings under the 80% ceiling.
