Many pilots are military veterans receiving medical disability compensation from the VA, as well they should for their service. The compensation and the medical conditions for which the compensation is awarded are reportable on the FAA MedXpress application, item 18, and failure to report can result in a denial or revocation of medical certificates if the FAA becomes aware of that discrepancy through an ongoing investigation now underway. Intentional falsification of a medical application is not a good way to win friends and influence people within the FAA. If you have questions about that or any medical certification issue, get in touch with the medical certification staff in the PIC. 800 872 2672.
