§ Mr. Dalyellasked the Secretary of State for Defence what research is being done at the Admiralty Materials Laboratory at Poole, Dorset, into the effect of cladosporium resinal fungus on the fuel systems of jet engines; and what he is doing to bring the results of such research to the attention of British industry.
§ Mr. John MorrisStudies at the Admiralty Materials Laboratory on the effects of cladosporium resinae have covered investigations of the environmental conditions necessary for growth, the associated corrosion of aluminium, and the possibilities of equipment malfunction caused by the particulate matter generated by the fungus. Recent work has also included assessment of the use of commercially available fungicides in fuels for defence applications and, in collaboration with the British Aircraft Corporation (Operating) Ltd., the ability of various fuel tank sealants to resist penetration and prevent corrosion by these micro-organisms. The results of work at the Admiralty Materials Laboratory have been and will continue to be published. Publicity has also been given to the work at the First International Biodeterioration Symposium held at Southampton in September and at the Admiralty Materials Laboratory Open Days in October. The Laboratory maintains close consultation throughout its44W work with the British aircraft and aero engine industry, oil companies and other Government Departments; advice and information is freely exchanged.
