Local Louisiana Plaquemines Parish Government (seal on the side of the rear fuselage) purchased this Piper Aztec in 2007 for mosquito control. It allows spraying in marsh areas unreachable by fog trucks.

Southern Seaplane has a seaplane facility and small airstrip beside a canal south of New Orleans near Belle Chase. In 1985, their business was primarily flying workers to offshore oil and gas production facilities in the Mississippi Delta not served by helicopters. The fleet was mostly Cessna 185s. The company acquired this DHC-2 Beaver, N53LP, from Dominion Air Lease Ltd. of Toronto in August 1984 (ex-C-GTER) and flew it until March 1990 when it was sold to Lake Union Air Service in Seattle and N91LU. On the date of the photo, the company was also overhauling two Grumman G-44 Widgeons.

This 1954 Beaver spent most of it's time as CF-HOE with Laurentian Air Services (1957 - 80). Next it went to Sweden as SE-GXX , initially with Tammert Aero AB. The floatplane was bought by Southern Seaplanes in December 1989.
