SUMTER, S.C. - Airmen from the 20th Aircraft Maintenance Squadron here get the sudsy job of washing aircraft, scrubbing down the jets at the wash-rack.
“No later than every 180 days each jet has to be washed,” said Tech. Sgt. Walter Smith, 20th Equipment Maintenance Squadron corrosion control NCO in charge.
Without regular washing, dirt, grime and exhaust cause corrosion to the jet’s protective paint.
“The jet comes in, it’s checked to make sure there aren’t any tanks on it, we tape everything up, make sure it’s good to go, and then we wash it,” said Airman 1st Class Courtney Swain, 20th Aircraft Maintenance Squadron weapons apprentice. “The longest part is the taping.”
Once everything is taped off, the aircraft is washed from top to bottom, including the landing gear and the wheels.
“When they’re done washing they rinse off all the soap and they determine if the jet is clean enough,” said Smith. “Then they start removing all the tape. And when their doing that, they call us out and we come and do a paint score.”
Following each aircraft’s wash, a corrosion paint-score inspection is completed in order to assess any corrosion.
“There are 10 sections of the aircraft that are assessed and scored from zero to five, five being the worst. Also there is one section that is assessed one point for every year that has passed since the last full paint date,” Smith added. “In all there are 11 sections that contribute to a paint score to determine the overall health of the aircraft coating system.”
During the paint score, airmen who wash the jet put all of the materials used for the wash back into two large lockers.
“Those are my materials and I am responsible for them,” said Smith, “so I have to make sure that they’re serviceable to keep using or if I need to replace anything in there. That way next time they come in to wash a jet, everything is serviceable and there won’t be any problems.”
After everything has been done, the paint score determines what happens to the jet next.
“If the jet receives a good score and doesn’t need any attention from us,” said Smith, “it just goes back out onto the flightline to resume the mission.”
