How often is a Boeing 777 serviced?
Under the previous MRBR, an airplane was pulled out of service for approximately 5 days to perform required maintenance checks every 25 months. The addition of 12 months to this maintenance interval provides significant financial and scheduling opportunities to 777 operators.
How often do airplanes get checked?
Inspection requirements differ with the various uses of aircraft. For example, aircraft being used for compensation or hire must have a thorough inspection every one-hundred hours. Most aircraft, including those used for compensation or hire are required to have a complete inspection every year (see annual inspection).
How often do jet engines get serviced?
Depending on the type, an engine has to be taken apart, cleaned and serviced every 3,000 or more flight cycles. This means an engine receives a major overhaul every five years, in addition to more frequent, less radical visits to the workshop.
How long are planes in service for?
about 30 yearsOn average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.
How much does it cost to service a plane?
As Savage says, planes hold value like houses. You don't need the newest model. What adds to that is engine servicing. That plane's engine needs an overhaul every 2,000 hours of operation, and that overhaul can run you about $30,000.
Do planes get checked before every flight?
Yes, pilots of airliners do a walk around to visually check the aircraft before every flight, just like pilots of smaller planes do.
What is the lifespan of a jet engine?
Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more. With most business jets accumulating less than 500 hours of flying time a year, the schedule for modern jet engine MRO operations averages about 12 years or more.
Do planes break down often?
If just the engines fail Engine failure on airplanes is pretty rare. It's happened fewer than 10 times in the past 20 years -- most memorably in 2009 when an Airbus A320 belly-flopped into the Hudson River.
How much does a 747 engine cost?
The Boeing 747-8 uses 4 General Electric GEnx engines, which cost $13 million each, meaning that replacing all four of a Boeing 747-8's engines costs $52 million.
What is the oldest plane still flying?
The oldest plane still flying in the world is the Bleriot XI. And it's not even close! Where generations of aircraft have been built and retired in its wake, the Bleriot XI, one of the first planes ever, built in 1909, still flies in Hudson Valley, New York.
Where do retired planes go?
And when a jet is retired indefinitely, it is usually sent to an aircraft boneyard (or graveyard). Boneyards are often located in deserts as dry weather conditions help to limit corrosion. In these facilities, the valuable parts of an aircraft are removed for reuse or resale before the rest of it is scrapped.
How often do airplane tires get changed?
every 120 to 400 landingsTires are changed every 120 to 400 landings depending on a number of factors. Aircraft tires need to withstand an extremely wide range of temperatures that go from minus 60 degrees Celsius at an altitude of 10,000 meters to extremely high temperatures when landing in the world's hottest regions.
How well are planes maintained?
Modern airliners are very reliable, robust machines, logging thousands of hours in the air each year, though the number varies by operator. For the sake of cost efficiency, most airlines do progressive maintenance which minimizes the downtime.
How do they test airplanes?
To simulate the forces that jet wings experience while flying, during the assessment the technicians can stack bags of sand on top of them, or build a cage-like structure around the airplane to force the wings upwards to determine the breaking point. The plane wings also undergo a fatigue test and static assessments.
Do planes take a break?
Commercial jet transport aircraft come to a halt through a combination of brakes, spoilers to increase wing drag and thrust reversers on the engines.
Do airlines do their own maintenance?
It is usually done at the airport gate and covers basic inspection checks. Engineers and technicians check wheels, brakes, and fluid levels, for example. Airlines do their own maintenance or, sometimes, use specialized companies like MROs.

How often do commercial airplanes need maintenance?
Commercial airplanes require frequent maintenance to offer a safe flying experience. They typically undergo a basic maintenance inspection once every two days, followed by a more thorough heavy maintenance inspection once every few years.
How often do you need to inspect a commercial airplane?
Along with a basic inspection — which occurs once every two days on average — commercial airplanes undergo a heavy maintenance inspection. A heavy inspection, as the name suggests, involves a more thorough evaluation of the commercial airplane’s. A heavy maintenance inspection typically occurs once every few years. During a heavy maintenance inspection, a team of maintenance professionals will thoroughly check most of the commercial airplane’s components. They’ll look for signs of corrosion, loose fasteners, worn parts and other signs of fault that need addressing.
Why is flying safer than driving?
One of the reasons why flying is so much safer than driving is because of the extensive work that goes into maintaining commercial airplanes. Most commercial airplanes are inspected by a team of maintenance professionals at least once every two days. During this inspection, maintenance professionals will check the commercial airplane’s fluids to ensure they aren’t low. Maintenance professionals will also check the commercial airplane’s tires. If they are low on air, they will pump them to the appropriate pounds per square (PSI) of pressure.
Is it safer to fly or drive?
Flying aboard a commercial airplane is undoutedbly safer than driving. Research shows that flying, in fact, is nearly 20 times safer than driving. In any given year, there are approximately 6 million car accidents in the United States. The rate of commercial airplane crashes is much lower. In most years, there are no fatal airplane crashes.
Why is maintenance important?
Before we talk about the types of upkeep, and how often is it done, let’s first delve into why is it so important.
Types
There are several different types of upkeep that every aircraft goes under, and the time frame when this is done depends on the type of maintenance needed.
How often is it done?
When it comes to specific schedules, as we mentioned before, it all depends on the type of upkeep that is scheduled. According to experts, the most basic type of upkeep, line one is done every week, and each craft will spend half a day in this type of check. Know that this type of care is done all around the world, every moment of every day.
How often is an airplane taken out of service?
Every couple of years, the airplane is taken out of service for what's called a "heavy" maintenance check. During this process, nearly all access panels are opened and parts of the plane – including the interior – are removed for closer inspection.
Why are older airplanes retired?
In fact, most older airplanes are retired for fuel-efficiency reasons, not because they're worn out.
How reliable are airliners?

What happens if a passenger becomes ill on a flight?
If a person becomes ill on a flight, crews are trained to provide first aid. Additionally, many airlines have a medical specialist available via phone or radio patch. If the passenger is ill and needs more medical attention, the captain can decide to divert.
Why is maintenance important in aviation?
Every Aircraft Needs Maintenance. Aviation maintenance is crucial for safety and making sure that aircraft are able to fly without any problems! In the United States, airlines and other commercial operations of large or turbine-powered aircraft adhere to a program approved by the Federal Aviation Administration (FAA).
What are the factors that determine the frequency of an aircraft's maintenance?
Two major factors of the frequency of an aircraft’s need for servicing are flight hours and age. Furthermore, it’s important to remember that all aircraft are different and may require maintenance checks at different times than others.
What is timed maintenance?
Timed Maintenance. The amount of flight hours makes a large difference in how often aircraft need maintenance. Many airlines and operators create their own plans of maintenance, which depends on the frequency a specific aircraft is in service. Aircraft have set checks at various intervals, often known as flight line maintenance checks ...
What are the different types of maintenance checks?
Aircraft have set checks at various intervals, often known as flight line maintenance checks and also four different types of higher-level maintenance: A, B, C, and the heaviest (D) checks. Line maintenance is the most frequent and often includes the most basic of inspections.
How does age affect aircraft?
Aging effects, such as wear, deterioration, and corrosion occur over time. If not managed, these effects can be a significant safety concern.
