Abstract : The BELL 206-B1 helicopters at Oakley Army Air Base are often placed in storage hangars, for periods of 90 days or more. The OEM recommends the aircraft should be stored in a special plastic protective bag and a dehumidifier attached to the protective bag. The use of this protection may not be warranted since the measured rate of corrosion in the storage facilities, using the CLIMAT or wire on bolt assessment method, indicates that the corrosion rate is 'negligible' for the assessed 12 month period. Additional to this evaluation, testing of Water Displacing Corrosion Preventatives (WDCP's) was carried out. The results clearly show that at the exposed Oakey sites, the WDCP's provided very good protection.
