A Check Aircraft - Aircraft maintenance checks are periodic inspections that have to be done on all commercial/civil aircraft after a certain amount of time or usage. (military aircraft normally follow specific maintenance programs which may or may not be similar to those of commercial/civil operators).
Airlines and other commercial operators of large or turbine-powered aircraft follow a continuous inspection program approved by the Federal Aviation Administration (FAA) in the United States,or by other airworthiness authorities such as Transport Canada or the European Aviation Safety Agency (EASA).
A Check Aircraft
Under FAA oversight, each operator prepares a Continuous Airworthiness Maintenance Program (CAMP) under its Operations Specifications or “OpSpecs”. The CAMP includes both routine and detailed inspections. Airlines and airworthiness authorities casually refer to the detailed inspections as “checks”, commonly one of the following: A check, B check, C check, or D check.

A and B checks are lighter checks, while C and D are considered heavy checks. (g) The flight segments or line-observation program required in paragraph (f) of this section are considered to be completed in the month required if completed in the calendar month before or the calendar month after the month in which they are due.
Any airplane is a tuned machine that has primary systems and backup systems. They allow the aircraft to fly increasingly longer distances and be one of the most efficient technology pieces ever built. That's why you still see a lot of old aircraft still flying around.
If a plane from the 1950s has proper maintenance, it can still fly. (1) A check airman (aircraft) is a person who is qualified to conduct flight checks in an aircraft, in a flight simulator, or in a flight training device for a particular type aircraft.
Wherever you want to go in this world, chances are aviation maintenance can get you there. And once you arrive, that's only the beginning. National Aviation Academy's (NAA) hands-on career training will prepare you for the limitless opportunities available in maintenance aviation.

His specialist knowledge of Latin American airlines and close relationship with the likes of Aeromexico, Avianca, Volaris brings depth to our coverage in the region. Based in Mexico City, Mexico. As any technician knows, every aircraft on commercial service receives line maintenance around the clock.
This type of maintenance is the most routine, sometimes even called post-flight or pre-flight. It is usually done at the airport gate and covers basic inspection checks. Engineers and technicians check wheels, brakes, and fluid levels, for example.
The D Checks take about three to six weeks and costs several millions of dollars. Once it is done, the plane is almost like a brand new aircraft. However, when an aircraft receives between two or three D Checks, it may become more costly than the plane's actual value.
Then, it is time to retire the aircraft (or resell it). Answer an essay questions with less efforts. how? we have list down, how the examiner mark an essay answer.so read this article to find out what are the key points they look for in an essay answer.
Answer essay. When marking a question, it must be borne in mind that the minimum experience required can… Line maintenance: The maintenance is done on the flight line, basically on the apron out in the open. Line maintenance can be up to A check.
Base maintenance: The maintenance work is done in a hangar, with appropriate platforms perform access aircraft components.Special tools and equipments are used. Third-party just means that someone else than the… D CHECKThis is by far the most comprehensive and demanding check for an airplane.
It is also known as an IL or “heavy maintenance visit” (HMV). This check occurs approximately every 6 years. It is a check that more or less takes the entire airplane apart for inspection and overhaul.
Even the paint may need to be completely removed for further inspection on the fuselage metal skin. Such a check can generally take up to 50,000 man-hours and 2 months to complete, depending on the aircraft and the number of technicians involved.
It also requires the most space of all maintenance checks, and as such must be performed at a suitable maintenance base. The requirements and the tremendous effort involved in this maintenance check make it by far the most expensive, with total costs for a single visit ending up well within the million-dollar range.
A CHECKThis is performed approximately every 400-600 flight hours or 200–300 cycles. (takeoff and landing is considered an aircraft “cycle”), depending on aircraft type. It needs about 20–60 man-hours and is usually performed overnight at an airport gate.
The actual occurrence of this check varies by aircraft type, the cycle count, or the number of hours flown since the last check. The occurrence can be delayed by the airline if certain predetermined conditions are met.
“My instructors were knowledgeable about the subjects, and able to give me tips and tricks beyond the curriculum to improve my understanding of the material. With their support and National Aviation Academy's curriculum I was able to, not only get my certifications, but secure employment!”
IDG ( integrated drive generator) is a Electrical generator which provides Electricity for the Aircraft. IDG provides electrical power for All the aircraft systems. It consists of a generator and a Constant Speed Drive (CSD). The generator uses the kinetic Energy of the Aircraft Engines and convert it into Electrical energy.
CSD coverts variable input of the engine… Then, every eight to 10 weeks, airplanes need what is known as the A Check. In this process, technicians change filters, check, and lubricant critical systems. They also give a detailed inspection of all the emergency equipment.
The A Check takes between six and 24 hours on a narrowbody aircraft. Finally, the D Checks are the heaviest maintenance visit of them all. It occurs every six to ten years, and it involves comprehensive inspections and repairs of the entire aircraft.
Technicians basically dismantle the airplane and put it back together. As Qantas said, Aircraft require tons of maintenance. Every single day, an airplane receives some sort of care to keep it tuned and ready to fly.
The aviation industry is all about safety, and it can't tolerate the absence of an effective inspection and maintenance program. If airlines worldwide weren't checking their fleets constantly, there would be an increased chance of failure.
But how do airlines define maintenance? What's an A Check? Why is there no longer a B Check? Let's investigate further. C CHECKThis is performed approximately every 20–24 months or a specific amount of actual flight hours (FH) or as defined by the manufacturer.
This maintenance check is much more extensive than a B check, requiring a large majority of the aircraft's components to be inspected. This check puts the aircraft out of service and until it is completed, the aircraft must not leave the maintenance site.
It also requires more space than A and B checks. It is, therefore, usually carried out in a hangar at a maintenance base. The time needed to complete such a check is generally 1–2 weeks and the effort involved can require up to 6,000 man-hours.
The schedule of occurrence has many factors and components as has been described, and thus varies by aircraft category and type. Before the introduction of large jet aircraft, like the Boeing 707 and the DC-8, maintenance was done by pilots and mechanics based on their individual experiences.
They created simple programs without proper analysis. However, the appearance of airlines and jetliners shed light on the necessity of regulation and a maintenance program development. (d) Completion of the requirements in paragraphs (b) (2), (3), and (4) or (c) (2), (3), and (4) of this section, as applicable, shall be entered in the individual's training record maintained by the certificate holder.

B CHECKThis is performed approximately every 6-8 months. It needs about 120-150 man-hours, depending on the aircraft, and is usually completed within 1–3 days at an airport hangar. A similar occurrence schedule applies to the B check as to the A check.
However, B checks may also be incorporated into successive A checks, i.e.: Checks A-1 through A-10 complete all the B check items.

Meanwhile, there used to be a B Check. Operators have phased out these Checks and merged them into the A Checks. The B Check used to be made every six to eight months. It took up to 180 labor hours and could be completed within one to three days at an airport hangar.
Because of the nature and the cost of such a check, most airlines — especially those with a large fleet — have to plan D checks for their aircraft years in advance. Often, older aircraft being phased out of a particular airline's fleet are either stored or scrapped upon reaching their next D check, due to the high costs involved in comparison to the aircraft's value.
On average, a commercial aircraft undergoes three D checks before being retired. Many maintenance, repair and overhaul (MRO) shops claim that it is virtually impossible to perform a D check profitably at a shop located within the United States.
As such, only a few of these shops offer D checks. (b) No certificate holder may use a person, nor may any person serve as a check airman (aircraft) in a training program established under this subpart unless, with respect to the aircraft type involved, that person -

“I think a lot of women are intimidated by this kind of work or they see themselves in a cookie-cutter role. I hope that more women will get into trades and technical work like this because there's a demand for it.
At the end of the day it feels really good knowing that I'm helping pave the way for women coming up behind me.” In the United States, initial aircraft maintenance requirements are proposed in a Maintenance Review Board (MRB) report[5] report based on Air Transport Association (ATA) publication MSG-3 (Maintenance Steering Group – 3rd Task Force). US)Modern transport category airplanes with MSG-3-derived maintenance programs employ usage parameters for each maintenance requirement such as flight hours, calendar time, or flight cycles.
Maintenance intervals based on usage parameters allow more flexibility in scheduling the maintenance program to optimize aircraft utilization and minimize aircraft downtime. Given the time requirements of this check, many airlines use the opportunity in order to also make major cabin modifications on the aircraft, which would otherwise require an amount of time that would have to put the aircraft out of service without the need for an inspection.
This may include new seats, entertainment systems, carpeting, etc.
