Aircraft Maintenance Technicians
Maintain and repair aircraft structures, and avionic and mechanical systems.
A night shift in the hangar
You are an aircraft maintenance technician on a night shift, working on a small passenger aircraft that is due to fly at dawn. It is 11pm. The aircraft has a list of jobs to complete before morning, two of your team are on break, and the operations manager has just texted you for a time.
Choose what you would do. Then see what happens. There are often good reasons for each choice.
I am looking at tomorrow's flights and this aircraft is the only one that can do the 6am run. How is it going? I need to know it is going to be ready, because we have a full load booked on it.
Say it will be ready, to avoid starting a panic at midnight
Davor plans around your word and cancels the backup aircraft. At 4am a job takes longer than you expected, and the early flight is cancelled with no cover. A promise made before the work is done is not a plan.
Give him a true status, what is still open, and when you will know for sure
Davor keeps the backup aircraft on standby and asks for an update at 3am. You finish with time to spare, and he trusted the plan because it was honest.
Say you cannot give a time and he should check with the licensed engineer in the morning
You are right that the engineer signs off the work, but Davor needed something to plan with tonight. A rough shape of the night is within your reach.
I have a part here from the store that is a close match for the one on the job card. The paperwork is a bit different but it is the same size. Do you want me to sign it in so you can fit it? It will save an hour.
Fit the part, since it is the same size and it saves the hour on a night that is already tight
Later, the records show a part number that does not match the aircraft's approved list. The aircraft is grounded until it is replaced. In aviation, a close match is not an approved part.
Ask Kwame to take the decision, since he is the licensed engineer and it is his sign-off
He decides correctly, but you have not looked at the part yourself. Technicians who know why a rule exists are the ones who catch what the paperwork misses.
Ask Kwame to hold, check the part against the manual, and wait for the right one
The part is not approved for this aircraft. The correct part is found in the store with a bit more digging. You lose less than an hour and the aircraft stays legal.
I dropped a small bolt inside the wing panel when I was closing it up. I think I can see it, but I cannot reach it. The panel is almost shut and we are running behind. Should I just leave it?
Tell Pia to leave it, because it is small and the panel is nearly shut
It is only a small bolt, but loose items in an aircraft can cause real trouble. You catch yourself and reopen the panel. A moment of doubt was the right instinct, and it should have come first.
Open the panel, retrieve the bolt, record the incident and thank Pia for telling you
The bolt is found and the panel closed properly. Pia was nervous about telling you, and your thanks makes her more likely to speak up next time. In aviation, an honest report is worth more than a perfect record.
Close the panel and say nothing to anyone, to avoid getting Pia into trouble
Nobody knows there is a loose bolt in the wing. It is found weeks later during an inspection, and the team has to explain why it was never reported. Protecting a colleague by hiding a problem protects no one.
How it went
The aircraft is signed off a little after five, and the first passengers board just as the hangar lights go off. Aircraft maintenance means precision, honesty about what you have and have not checked, and a lot of patience at night. Could you carry that responsibility each time you sign your name?
This is a simplified, fictional situation to help you explore. It is not professional instruction or a test of your ability.
Case study: The fault that came back on every flight
A fictional case set in a fictional regional airline hangar, where aircraft come in for scheduled checks and overnight fixes.
The situation
Ilsa was an avionics technician at Bluegum Air, working a night shift. A small regional aircraft had reported a warning light that came on in flight and went off again, three times in a week. Each time, the previous shift had cleared the log and returned it to service. The aircraft was scheduled to fly at six the next morning, and the operations manager, Davor, asked when it would be ready.
What they did
Ilsa read the previous reports, then traced the wiring behind the instrument panel. She found a connector that was slightly worn and intermittently losing contact, which is why the fault disappeared when she tested on the ground. She replaced the connector, tested the system for a long time, and recorded exactly what she found. She told Davor the aircraft would be ready, but only after the testing was finished.
How it turned out
The aircraft left forty minutes late and the warning never returned. Davor was not pleased about the delay, but changed the shift handover so that repeated faults were flagged to a senior engineer. Ilsa's notes were used in training the next group of technicians.
What would you do?
- Why do you think the earlier shifts cleared the fault and moved on?
- How would you feel about being the person who has to say an aircraft is not ready?
- What would make a good written record for the next person who needs it?
