Abstract
Five Airforce Wing Maintenance Facilities were visited to determine the current practices used to dry strip aircraft components using plastic media. It was observed that the current equipment is old (over 20 years) and is in need of replacement and that some of the blasting practices used by the technicians were not compliant with the current CF dry media blasting specification. A new non-toxic, biodegradable cornstarch dry stripping media (Type VII) was demonstrated to the technical staff. The use of Type VII media at other facilities (US Army, Airforce, Navy and Coast Guard) was examined to determine what would be required to introduce this media into fleet operations. The Type VII media has several advantages over the current media, such as no surface residue after blasting, odourless, can be used on composite and fibreglass surfaces and imparts less residual stress to the blasted surface. The Type VII media is a drop-in replacement for the current media and no equipment changes are required if the Type VII media is specified for use by the Wing Facilities.
