A Compendium of Bonded Repairs Applied to the PC9/A Full Scale Fatigue Test Article During Testing
Abstract
A number of bonded composite repairs were applied to the PC9/A full-scale fatigue test article during its fatigue test to help achieve the target of greater than 50,000 simulated flight hours. The aim of the test was to provide RAAF with data to enable the through-life structural fatigue management of PC9/A aircraft in their fleet Bonded repairs were applied to cracks that occurred in the wing centre-section on the lower wing skin and in the fuselage skin near the tail fin. The repairs were successful in stopping crack growth in the skin without affecting stresses in the underlying spars, which was critical in allowing proper lifting calculations. This report lists all the bonded composite repairs applied and for each repair, details its location, geometry and design and application notes. while the repairs were applied primarily to assist the smooth running of the fatigue test some of the repairs provide a starting point for design of future repairs to RAAF aircraft should cracking occur or if they are to be applied as a preventative measure at the same locations.
