It must be noted that this problem must apply to all glider and powered sailplane types which utilize wood as part of their GRP structure and carry water ballast. GFA AD's 159 and 165 also address this problem. All materials required are available from the manufacturer:- NOTE: An Australian equivalent to "AIDOL" can be provided by the GFA CTO/A.
