CHAIN-O-LAKES
SOUTH BEND, IN
Chain-O-Lakes, identified as 3IN7, is a privately owned, non-towered airfield in South Bend, Indiana. A lone turf and sand runway, 15/33, serves the field, measuring 2,100 by 125 feet.
No published instrument approach procedures exist, so the field is used under visual flight rules. The non-towered field operates under see-and-avoid procedures, with pilots coordinating their own arrivals and departures. The field has no fuel sales on record. Its private-use designation means pilots need the owner's permission before landing.
The airport sits at 743 feet above mean sea level.
