The Auster J-1U Workmaster was a 1950s British single-engined single-seat high-wing agriculutural monoplane built by Auster Aircraft Limited at Rearsby, Leicestershire.

History

Following the experience of developing the J-1B Aiglet agricultural aircraft, Auster developed a large more powerful successor the J-1U Workmaster. Using the basic Autocrat fuselage it was strengthened and had dorsal fin fillets added, low pressure tyres and a 180 hp (134 kW) Avco Lycoming engine.

The aircraft were fitted with Britten-Norman rotary atomizers for crop spraying and a 100 imperial gallon (455 litre) chemical tank in the fuselage. An emergency dump valve allowed the tank to be emptied in 5 seconds.
