Checking aircraft before flight


How to check the technical condition of the aircraft?

Accidents aircraft are always associated with a large number of dead people. That is why these catastrophes receive wide publicity, widely publicized in the media. In simple layman, who is not associated with the technique, and little interest in it, he might get the impression that in recent years too often began to fall planes. Some people begin to fear air travel, citing the decision of the high probability of getting in a plane crash, or of accidents.

Layman, a passenger, it seems that the planes "old", for no one is watching, and "it can fall apart in the air." These fears are supported by some unscrupulous media correspondents, or by virtue of its full not competence or in the pursuit of "fried" news.

Causes of any plane crash - a tragic chain of circumstances, factors, none of which can not alone lead to tragedy, and together played a role in the crash.

It should also be remembered that the cause of 70% of all accidents is the so-called "human factor". It is not only the error of pilots, it miscalculations ground specialists, dispatchers and technicians, actions of passengers and the actions of terrorists.

Well, in this article, I want to dispel some of the most enduring and popular among the myths of passengers: the old aircraft, that aircraft will fall apart in the air, and that no one was watching over the technical condition of the aircraft, and if so, it is very bad, etc.

So, 30% of the remaining accidents and disasters is necessary not only to a failure of equipment, these percentages also includes undisclosed causes of the crash, unsolved because of the inability to ascertain the cause of an accident or crash. Of course, any technique breaks down and fails, but in aviation entered a number of mandatory procedures for the equipment, which does not pass the aircraft simply can not.

So, how and when to check the technical condition of the aircraft?

The basis of the fleet of domestic airlines to make foreign planes. Therefore, manufacturers of hardcoded all the checks that are necessary to pass the aircraft.

Sun checks are made:

  • After a certain amount of time.
  • After a certain number of hours.

That is, even if the plane did not fly, and was laid up, then prior to departure, he must pass certain set of maintenance and technical checks, clearly regulated by the manufacturer. Each BC has a THEN map in which each professional action, every kind of work is registered and the status of implementation Stamp, confirmed by the controlling person.

How many of these inspections? How and where are they?

Listed below are all kinds of inspections (check) conducted on the Sun, and it should be borne in mind that each successive test harder and better the previous one, and includes all of its checks.

Aircraft maintenance:

  • Transit check - transit
  • Daily check - daily
  • Weekly check - weekly

This so-called "mild forms of that." Accordingly, the title they held promptly: transit check - before each flight, daily - Every day every 24 \ 36 hours. Usually carried out at night. Weekly TO -  about once a week, can be carried out both in the hangar and in the open parking lot, day and night.

Then there are the so-called "mean that."

  • A-check
  • B-check

The first is carried out about once a month or every 500 flight hours. Produced often at night in the hangar of the airport or factory. It includes checks: A1, A2, A4, A8, and the higher the number, the greater the amount of work performed on the aircraft

B-check is made approximately every three months, and also in the hangar of the airport, mainly at night.

Please note, no one check does not cancel execution of all previous scans.

And finally, the most complex (difficult) types of inspections:

  • C-check - Every 15-24 4000 months or flight hours.
  • D-check - Once a year 10-12 and 1-1,5 last month.

This is the most complex and expensive kinds of technical checks for the aircraft. They are produced in specialized companies that have been certified for maintenance and R for these types of aircraft, either directly at the manufacturing plants.

To carry out any kind of C-check (C1, C2, C4, C6, C8) aircraft taken out of service for up to 3 weeks. It is located in a large hangar. Types of work, the number and complexity depend on many factors, from the type of AC.

When D-check the aircraft is completely disassembled into parts, assemblies and equipment. All parts are checked and changed or repaired if necessary. All load-bearing elements of the airframe are all kinds of inspection for cracks or fatigue stress in the power components.

Types of inspection methods conducted on the aircraft:

  • Penetrant testing.
  • Eddy current method
  • ultrasonic flaw detection
  • Magnetic powder control
  • X-ray inspection

As you can see, the whole plane undergoes a very thorough check by the most modern methods and on modern equipment. In fact, the plane gets a second life, reborn completely updated. And for an airplane there is no such thing as an "old" concept. There are widely known cases when, after a good overhaul, airplanes of 30-X, 40-ies, and older ones rise into the air. They fly on parades, airshows, exhibitions, refuting the thesis of outdated technology. Of course, they do not carry passengers on 100-200, but among them there are, and passenger aircraft ready at least now to get into operation.

And yet, I would like to add a few words about the appearance of the aircraft. No need for him to judge the state of the aircraft and its safety. The new airplane is very costly coloration associated with the withdrawal of aircraft from the flight plan for a long time. Especially it is not cost-effective in the "hot" holiday season, in the summer. And it is in any case obsharpannost aircraft does not mean that for him no one is looking and not serving him. So fly safely, and you soft landings.
