๐ฐโ๏ธ DID YOU KNOW HOW EXPENSIVE AIRCRAFT PARTS CAN BE?
When we look at an aircraft, we usually think about the whole airplane. But some individual components are already worth millions! ๐ณ
For example, approximate list-price figures shown for some wide-body aircraft include:
๐ฅ Boeing 787 engine (GEnx-1B): about $20โ25 million
๐ฅ Airbus A350 engine (Trent XWB): about $32โ35 million
๐ฅ Boeing 777 engine (GE90): about $35โ40 million
๐ฌ Boeing 787 landing-gear set: about $5โ6 million
And some avionics units, such as ADIRU, can cost hundreds of thousands of dollars.
โ ๏ธ These are approximate list prices, not necessarily what airlines actually pay. Real prices can vary with supplier, configuration, quantity and agreements.
๐ง For future AMTs: this is one reason aircraft maintenance demands extreme care, accuracy and responsibility.

โ๏ธ WHY AIRCRAFT ARE WEIGHED AND BALANCED
Ever wondered why an aircraft needs to know its exact weight and balance before flying? ๐คโ๏ธ
Itโs not just about knowing how heavy the airplane is.
โ๏ธ Weight affects performance -a heavier aircraft needs more runway and more power for takeoff.
๐ฏ Balance affects control - the aircraftโs center of gravity must stay within approved limits.
โฝ Fuel is part of the calculation - as fuel burns during the flight, the aircraft becomes lighter and its balance can change.
๐งณ Passengers and cargo matter too - where people and baggage are placed can affect the aircraftโs center of gravity.
๐ง For AMT applicants: understanding basic concepts like weight, center of gravity, balance and aircraft loading gives you a better foundation for aviation training.
An aircraft doesn't just need enough power to fly it needs the right weight and balance to fly safely. ๐ซ

โ๏ธ HOW DO AMTs COMMUNICATE WITH PILOTS?
Many people think an AMT works only in the hangar or around the aircraft. But in real aviation, communication between maintenance and flight crew is extremely important. ๐ง๐จโโ๏ธ
For example, if a pilot notices an unusual indication, warning, noise, vibration, or technical problem during a flight, the issue can be reported through the aircraft's technical log/maintenance reporting system.
When the aircraft lands, maintenance personnel review the pilot's report and investigate the problem.
๐ The AMT may then:
- Understand exactly what the pilot experienced.
- Ask for additional technical information when necessary.
- Inspect or troubleshoot the relevant system.
- Carry out the required maintenance procedure.
- Test the aircraft/component after the work.
- Record and sign off the maintenance work according to authorization.
๐ Ethiopian MRO procedures specifically require pilot write-ups to be reviewed and cleared before the next departure, with troubleshooting and analysis performed by qualified line-maintenance personnel.
๐ฏ FOR AMT APPLICANTS:
You don't only need to know how an aircraft works.
You need to learn how to listen, understand technical information, communicate clearly, document correctly, and work as part of a team.
A pilot may describe what happened.
The AMT must help determine why it happened and what needs to be done.

๐น Flight-control surfaces - such as ailerons, elevators and rudders

Imagine an Ethiopian Airlines aircraft comes back from a flight and maintenance inspection finds damage or a dent near part of the fuselage.
An Airframe Technician doesn't simply look at it and say, โIt's small, so it's okay.โ

If required, the technician uses the correct tools to check dimensions, clearances, electrical values, pressure, continuity or other specified parameters.
โฑ๏ธ 4. CHECK ITS HISTORY & LIMITS
Some components have life limits, inspection intervals or other maintenance requirements. These records must be considered.
๐ ๏ธ 5. COMPARE THE RESULTS
The inspection or test results are compared with the manufacturer's specified limits not with personal judgment.

โ๏ธ CABIN CREW โ WHAT HAPPENS DURING THE PRE-FLIGHT BRIEFING?
Before passengers start boarding, cabin crew don't simply walk onto the aircraft and wait for people.
There is an important step first: the crew briefing. ๐ฉโโ๏ธ๐จโโ๏ธ
During the briefing, the crew may discuss:
๐ฅ Crew roles - who is responsible for which position and duties.
๐จ Emergency responsibilities - assigned exits, equipment and responsibilities in case of an emergency.
โ๏ธ Flight information - details about the flight, route and expected conditions.
๐ถ Special passengers - information about passengers who may need additional assistance.
๐ก๏ธ Safety & security - important procedures and anything the crew needs to pay attention to.
๐ค Team coordination - making sure everyone understands their role before the aircraft departs.
๐ฏ FOR CABIN CREW APPLICANTS:
One important lesson is that cabin crew work is highly team-based.
Every crew member needs to know:
โWhat is my job?โ
โWho do I report to?โ
โWhat should I do if something changes?โ
The briefing helps turn a group of individual crew members into one coordinated team before the flight even begins.

โ๏ธ AMT CABIN MAINTENANCE โ MORE THAN JUST THE PASSENGER SEATS
When people hear aircraft maintenance, they usually think about engines, wings or avionics.
But an aircraft also needs technicians who maintain the cabin systems and equipment passengers use every flight. ๐ง
๐ช Passenger seats & fittings
Checking cabin seats and related components for damage or defects.
๐ช Cabin doors & interior components
Inspecting and maintaining cabin doors, panels, compartments and other interior equipment.
๐ก Cabin lighting
Working with cabin lighting systems and identifying faults when required.
๐ป Lavatory & galley equipment
Maintaining various cabin equipment and systems used by passengers and crew.
๐ ๏ธ Cabin equipment
Inspecting components to make sure they are properly installed, secure and serviceable.
๐ REAL EXAMPLE:
Imagine a passenger reports that a seat tray table is damaged or won't lock properly.
It may look like a small problem, but the technician must determine whether it affects the safe use of the seat, inspect the component and follow the applicable maintenance procedure before the aircraft is released.
๐ฏ FOR AMT APPLICANTS:
Cabin Maintenance teaches an important lesson:
Aircraft maintenance isn't only about what makes the aircraft fly it's also about keeping the aircraft's cabin and its equipment safe and serviceable.

โ๏ธ SOMEWHERE BETWEEN THE RUNWAY AND THE DREAM
One day, you may stand beside an aircraft wearing the uniform you once imagined from far away.
But remember what nobody sees behind that moment.
The early mornings.
The pages of technical notes.
The questions you couldn't answer.
The applications.
The waiting.
The days when you wondered whether you were really good enough.
Aviation has a strange way of teaching you this:
You don't become ready when the opportunity arrives.
You become ready while you're waiting for it.
An aircraft doesn't leave the ground because someone hopes it will fly.
Thousands of details have to be right.
And maybe your journey is the same.
Study the things you don't understand.
Learn the aircraft.
Improve your English.
Build your technical knowledge.
Keep learning even when nobody is watching.

AIRCRAFT ENGINE DRIVEN PUMP
โ๏ธ The engine-driven pump (EDP) in a turbofan engine is primarily used to convert mechanical power from the engine accessory gearbox (AGB) into high-pressure hydraulic power for the aircraftโs hydraulic system.
โ๏ธ How it works
1. The turbofan rotates.
2. Mechanical power is taken from the engine through the accessory gearbox.
3. The gearbox drives the EDP shaft.
4. The pump draws hydraulic fluid from the supply/return system.
5. The pump pressurizes the fluid.
6. High-pressure hydraulic fluid leaves the pump through the pressure outlet.
7. The fluid travels to hydraulic actuators and other aircraft systems.
8. Leakage from the pump shaft/seals is handled through the case/seal drain system.

๐งโ๏ธ TODAY'S TIP FOR AMT APPLICANTS: LEARN TO THINK IN SYSTEMS, NOT JUST PARTS
If you're preparing for Ethiopian Airlines AMT, here's a tip that is easy to overlook:
Don't study an aircraft component by itself. Ask what system it belongs to, what its job is, and what happens if it fails.
Ethiopian Aviation University's AMT training covers areas from airframe, power plant and avionics to human factors, troubleshooting, EWIS and fuel-tank safety so understanding how systems connect is important.
For example, instead of only memorizing โhydraulic pump,โ think:
Pump hydraulic pressure actuator flight-control movement aircraft response.
That way, when you meet a technical problem, you're not just remembering a part youโre understanding the chain of operation.
๐ฏ Your preparation tip:
Whenever you learn a new aircraft component, write down just 3 things:
1๏ธโฃ What does it do?
2๏ธโฃ What does it work with?
3๏ธโฃ What could happen if it fails?
That's a much more useful habit for a future AMT than simply memorizing names. ๐งโ๏ธ
