Base Repair Depots (BRD) carry out fourth line repair and maintenance of aircraft and equipment in the Inventory of the IAF. These includes, overhauls, major repairs and major upgradations.
All BRDs have the same crests, depicting the legendary phoenix rising out of flames with a machine wheel encircling its head. The motto is common to all “Kaya Kalpa” which means rejuvenation of the body. The exception to this is No.1 BRD which retained its older “Sahayata Seva” motto and crest.
