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. The Workmasters were mainly operated in West Africa, three later returning and are currently (2009) on the U.K. civil aircraft register. ==Specifications (J/1U)== ==References== ==Further reading== ==External links== Auster Workmaster promotional brochure (PDF)
