The De Havilland Canada DHC-3 Otter was a rugged and tested light transport aircraft that was inducted into the IAF in 1962. The aircraft, a single engined tail dragger was the last piston engined transport to be operated by the Indian Air Force. When in service, it was flown by two squadrons in the Indian Air Force. The first squadron to be raised on them took on their name and were known as No.41 'Otters' Squadron. About forty or so aircraft had been procured by the IAF and had been used extensively in the North Eastern states for supply duties.

The aircraft were phased out in the early 90s, with both the squadrons reequipping with the Dornier 228 Light transport aircraft. Since the DHC-3 Otter was a very much sought aircraft in Canada and other parts of the world, most of the phased out aircraft were sold by auction.
