This paper presents two examples of research projects initiated by the Defense Research Establishment Pacific in direct support of aircraft operators and maintainers in the Canadian Armed Forces. The first example involves a contract research project at The displacing corrosion-inhibiting preparations on the fatigue characteristics of structural joints. The initial experimental plan is outlined. Preliminary results indicate that the preparations did not have a significant effect on the fatigue life of single-strap, riveted butt joints. The second example concerns the prohibition against use of silicon carbide abrasive papers on aluminum in aircraft. Laboratory investigations, including several electrochemical experiments and atmospheric exposure trials, clearly demonstrates that the use of silicon carbide abrasive papers did not increase the severity of corrosion.
