The Seabird Seeker is a light observation aircraft built originally by Seeker Aviation Australia and Seabird Aviation Jordan. Since 2016 it has been manufactured in the US by Seeker Aircraft (US)/Erickson. It is powered by a Lycoming O-360 engine. The aircraft is marketed as a low cost alternative to observation helicopters for the military and civilian sectors. It can be used in roles such as pipeline inspection, coast watch, environmental duties, aerial photography and security. The Seabird Seeker has had some export success, and is operated by the Iraqi Air Force .

As of 2016 Seekers are currently flying in Australia, Jordan, Azerbaijan, South Africa, Tanzania, UAE, and the US with the New Mexico State Police, among other operators.

US acquisition and manufacture

In March 2014 Seeker Aircraft (US), a subsidiary of the global aviation company CSI Aviation, acquired Seabird Aviation, the Australian manufacturer of the Seabird Seeker, with plans to eventually move Australia-based manufacturing operations to the United States In March 2016 Seeker Aircraft (US) announced that Erickson Inc. of Portland, Oregon, would begin manufacturing the Seeker aircraft in the United States In the US the Seeker aircraft has FAA Part 23 Normal Category certification, allowing use for commercial operations.

Operational history

Two SB7L-360A Seekers were purchased by the United States in 2004 in response to an initial requirement for eight fixed wing observation aircraft to equip the new Iraqi Air Force under the command of the Coalition Provisional Authority. The aircraft were received into service on 29 July from Seabird Aviation Jordan, and from 7 August Iraqi pilots received initial training on the Seekers. The two aircraft were airlifted by the United States Air Force to Basrah Airport on 18 August. The post-invasion IqAF's first flying squadron, No. 70 Reconnaissance Squadron was raised to operate the Seekers on patrol missions to monitor critical infrastructure such as oil pipelines and electricity transmission assets, as well as national borders. Initial missions saw coalition personnel accompany Iraqi pilots in a training capacity. On September 15, the Iraqi Air Force flew its first solo mission, crewed by two Iraqi pilots to provide intelligence on an oil pipeline spill. Although further procurement of the type did not eventuate after the selection of the SAMA CH2000, Seekers YI-101 and YI-102 continued to operate throughout the conflict successfully, providing capabilities, including real-time feeds of observations to ground forces, night surveillance and carrying digital video equipment to assist with target identification. The Seekers remained in service when the squadron relocated to Talil Air Base in 2010.

Variants
