Design and development

Using experience as sailplane designers and builders, Josef Oberlerchner Holzindustrie determined to create a powered aircraft. The result was the JOB 5,[1] a two-seat side-by-side light aircraft of wooden construction.[2] It first flew in 1958. The company decided to build a slightly larger three-seat production version, the JOB 15. The JOB 15 was a low-winged monoplane of composite construction with fixed tailwheel undercarriage, with a wooden wing and steel-tube fuselage covered in glass-reinforced plastic and fabric. The prototype first flew in 1960 with a 135 hp (101 kW) Avco Lycoming O-290-D2B engine. Three aircraft were built before the a more powerful version, the JOB 15-150, was built with a 150 hp (112 kW) Avco Lycoming O-320-A2B engine. After 11 15-150s had been built an improved version, the JOB 15-150/2, was introduced and ten were built before production ended in the late 1960s.
