MAINTENANCE
ICAO PRACTICE TEST VIDEO
TRANSCRIPT (CORRECTED)

But the maintenance workers at South West Airlines are just getting started.

Tonight they are going to open up a 737-700.

Almost 40 inspectors and mechanics are going to spend the night making sure the plane is fit to fly.

To keep airplanes in peak condition they get more health checks than most passengers.

Passenger planes are examined every time they come to a stop.

This is the A check.

A brief walk-around inspection turns up the most obvious problems.

The more intensive work is done at set intervals.

These are the B and C checks.

Tonight workers are performing a C check.

From start to finish it can require hundreds of man-hours of work.

It all has to get finished tonight, so the plane is back flying in the morning.

It’s a massive challenge, because modern jets are made of hundreds of thousands of individual pieces.

In 1903 when the Wright Brothers took their historic first flight near Kitty Hawk, North Carolina their plane had some 1,500 parts.

A 737 has more than 360,000.

You have to ensure that every one of those components is doing its respective job.

It doesn’t matter how big the part is. A missing screw can jeopardize the safety of flight.

Tonight the inspectors discover a tire on one of the main landing gears is worn out.

They add it to the list of unscheduled maintenance items.

It has to be replaced before the plane goes back into service.

In Phoenix Arizona, flight engineers continue their C check on the 737.

It includes testing the plane’s rudder.

The rudder is one of the jet’s most vital control surfaces.

It allows the plane to turn left and right.

A problem here could have terrifying consequences.

It’s 7.00 a.m. After an 8-hour shift the maintenance is finished on this South West Airlines 737.

According to their maintenance reports, the team has conducted 78 unscheduled procedures and 339 scheduled inspections.

Sometimes we obscure the fact that we fly millions and millions and millions of people day in and day out without putting a scratch on even the airplane, let alone the people.

This is the most amazing system.

This system depends on the dedicated team of professionals committed to taking care of these 21st century masterpieces.

Planes so well built that they could fly almost as long as we are willing to take care of them.

We’ve learned now how to inspect and maintain these things, and even rebuild them, to where they should have an indefinite life.

They’re built tough and they should be able to last forever if they’re maintained
properly.

1) What is the priority of the ground staff at the time? How many people are involved in the procedure?
Making sure the plane is fit to fly is the priority of the ground staff at the time. Almost 40 inspectors and mechanics were involved in the procedure.
2) How can perfect technical condition of an aircraft be provided?
Passenger planes are examined every time they come to a stock. This is the “A” check. A brief walk around inspection turns of the most obvious problems. The more intensive works are called as “B” and “C” checks.
3) What kind of checks does every aircraft regularly go through?
Passenger planes are examined every time they come to a stock. This is the “A” check. A brief walk around inspection turns of the most obvious problems. The more intensive works are called as “B” and “C” checks.
4) What are the purposes of A, B and C- checks?
Passenger planes are examined every time they come to a stock. This is the “A” check. A brief walk around inspection turns of the most obvious problems. The more intensive works are called as “B” and “C” checks.
5) What makes a C- check so challenging?
From start to finish C-check is most complicated check and it can require hundreds of person-hours of work.
6) How different are modern aircraft from those operated by the Wright brothers?
The Wright brother’s plane had some of 1500 parts. A 737 has more than 360 thousand parts.
7) Does the size of a component play an important part for the flight safety? What can missing or malfunction of any part result in? Do you know any examples of non-routine situations caused by maintenance errors?
No, the size of component doesn’t play an important role for the flight safety. Missing or malfunctioning of any part result in failures or even accidents with fatalities. I know about tragedy with Boeing 757 in 1996 near Lima, when mechanic forgot to delete protective tape from Pitot sensor.
8) What fault did the ground staff notice that time? What actions do they need to take to solve the problem?
The ground staff noticed worn out tire on main landing gear that time. They need to replace tire.
9) Why is checking the rudder so vital? What is the function of the rudder?
Checking the rudder is so vital because the rudder is one of jet`s most vital control surfaces. It allows the plane to turn left and right. A problem here could have terrifying consequences.
10) How many procedures did the ground staff perform during the C- check?
The ground staff performed 78 unscheduled procedures and 339 scheduled inspections.
11) According to the film, what does the maintenance system depend on? How can it ensure safety for all people flying?
Maintenance system depends on a dedicated team of professionals. Planes so well built that they could fly almost as long as they willing to take care of them.
12) Do you agree that under some special conditions any aircraft can fly forever? Why? Can you give examples of any aircraft types designed many years ago that are still in service?
Yes, I agree with this statement. If ground team inspects and maintains aircraft properly, aircraft may have an indefinite life. I can give a few examples of aircraft types designed many years ago: Antonov-2, Antonov-24, Tu-154, even Ilushin-18 is still on wing.
