I beg to differ, Mr. Mixson. What he's applying is actually duct tape....that thin, metallic tape that is used to seal up heating duct seams. At best, (worst, actually), what he should be applying is real "racer's tape". The only problem with that is it's also called "200 MPH tape", and those things fly at 3-500 MPH.
That guy should be a baggage handler, not an aviation tech.
Roger....former U.S. Navy aviation tech.....where we didn't use tape.
