Abstract

This paper gives an account of a life extension program carried out for the Gliding Club of Victoria (GCV) on the IS2SB2 sailplane manufactured by the Intreprinderea De Constructii Aeronautice Brasov, Romania. The GCV, based at Benalla in the North East of Victoria, Australia, have operated six IS28B2s for 15 years amassing a total of over 35,000 hours flying time and have found them excellently suited to their training operations. They therefore engaged the Royal Melboume Institute of Technology to undertake a comprehensive fatigue investigation to extend the life originally determined by the manufacturer. The first phase was a program to extend the safe fatigue life, followed by a second phase, which is strll in progress, to develop a safety-by-inspection procedure to extend the life still further by conducting regular irspections at calculated intervals.
