Development
The SZD-30 is largely constructed out of wood.[1] The high-mounted wing incorporates air brakes on both the upper and lower surfaces. The inner section of the wing is constant-chord and the outer section is tapered.[3]
The forward section of the otherwise all-wood fuselage is made of fiberglass.[1] The single-wheel main landing gear is fixed, the formed one-piece canopy is side-mounted,[4] the fuselage can be equipped with radios and an oxygen system. There are also two baggage compartments.[4]
Variants
- SZD-30 – Initial production version
- SZD-30B – A single prototype[5]
- SZD-30C – Later production version, with smaller partially balanced ailerons made of fiberglass, and a larger cockpit. The first -30C flew on 10 January 1978.[6]
Operational limitations
In 2011, following a number of cases of glue failure in the wooden joints, leading to structural failure, the type certificate holder issued a bulletin which reduced a number of the limiting speeds of the aircraft. Specifically, the maximum speed (VNE) was reduced to 195 km/h (121 mph, 105 knots) and aerobatic flight was prohibited.
