so Tod uses a lathe to make one out of stainless
steel.
6:15 Tod is now ready to finish the job. He brushes
alodine, a protective coating, onto the fitting. He
applies sealant to the new bearings and then freezes
them in liquid nitrogen. The freezing causes the
bearings to shrink, which makes them easier to
install into the fitting. Tod has to move quickly
once the bearings are removed from the liquid
nitrogen. He threads the bushing and bearing into
the fitting and then waits for the bearings and
sealant to return to room temperature and expand.
Then he tightens the assembly a bit more. He
cleans off the extra sealant with alcohol.
7:00 Tod gathers up all the tools, heads back to his
area, and enters the completed job into the system.
Then it’s on to the next task.

checks a computer system
for jobs that need completing. The
system displays the aircraft in the
hangar, the work that has been
done, and the work that’s still
needed.
2:50 Two worn bearings need
changing on an Airbus’s aileron
actuator. Tod determines what
supplies he’ll need to do the job.
3:00 He takes the paperwork for
the job to the stock module desk in
the hangar. The desk then gives him
the new bearings and the tools to
check out.
4:15 Once all the parts, tools, and paperwork are
checked, Tod enters specifics into the computer’s
job clock. Every job is tracked by how many hours
each person spends on it.
4:20 Sitting on a piece of cardboard under the
Airbus’s wing, Tod carefully pops out the two
old bearings. He cleans the fitting with a plastic
scraper to ensure there is no corrosion or damage.
4:45 An inspector is alerted to review the prep
work and give the OK before Tod installs the new
bearings.
5:12 After a quick break, Tod gets the approval
from the inspector. To start the job, he assembles
everything he’ll need, including rubbing alcohol,
sealant, a new tool kit, and liquid nitrogen.
6:10 The tool kit doesn’t have a bushing that fits,
