§ Mr. KeyTo ask the Secretary of State for Defence what his policy is on the use of Kapton insulation in military aircraft; and if he will make a statement. [91574]
§ Mr. SpellarKapton is a trademarked material. It is one of a range of polyamide coverings used to insulate aircraft wires. The MOD has been aware of potential problems associated with polyamide insulated wires since they were first identified in 1985. Accordingly the use of polyamide insulated wires in MOD aircraft is reviewed regularly. Work has included a detailed assessment of each aircraft installation; a review of defence standards on aircraft wiring; and work with the British Standards Institute to develop standards that are suitable for all airborne electrical wires and cables. We have also developed clear procurement guidelines and improved inspection and husbandry techniques. Decisions about wiring installations on MOD aircraft are made by experienced engineers who are responsible for assessing the risks and benefits, and for making safety and value judgments accordingly.
