Aviation Maintenance Technician interview questions and how to answer them

An airline or repair station interview for an AMT isn't really testing whether you can turn a wrench. It's testing whether you'll follow the maintenance program when the clock is running and nobody's watching. Expect questions about manuals, deferrals and inspection sign-offs, plus a few that check how you hold up on a night shift with a delayed flight hanging over you.

Part 1

1.A pilot writes up an inoperative item and the aircraft is due out soon. How do you decide whether it can be deferred?

Why they ask

Deferrals under the minimum equipment list are daily work at an airline, and a bad deferral puts an unairworthy aircraft in the air. They want to see that you know the process and your limits.

How to answer

  • Check the MEL for that item first: is it listed, and what category and repair interval does it carry
  • Do any maintenance procedures the MEL requires before release, such as deactivating or placarding the item
  • Coordinate with maintenance control, which often assigns the deferral and tracks it
  • Write the logbook entry with the MEL reference and make sure operations and the crew know about the placard
  • If it isn't in the MEL, it gets fixed before the aircraft goes

2.What's a required inspection item, and what changes when a task is an RII?

Why they ask

Carriers designate certain tasks, often on flight controls and engines, for independent inspection. Knowing the concept tells them you've worked inside an airline-style program.

How to answer

  • An RII is a task the carrier's manual says must be inspected by a qualified person who didn't do the work
  • You stop at the inspection point and call the inspector before closing panels or moving on
  • You never buy back your own RII, even if you hold inspection authority
  • Name an example you've seen, like a flight control cable rigging or an engine mount change

3.How do you find the right procedure for a task you've never done on this aircraft type?

Why they ask

You'll work on systems you haven't touched before. They want someone who reaches for approved data, not memory or a coworker's shortcut.

How to answer

  • Use the ATA chapter to get to the right section of the aircraft maintenance manual
  • Confirm the manual revision is current in the carrier's document system
  • Pull part numbers from the illustrated parts catalog and check effectivity for that tail
  • Read the whole task, including warnings and the closeout steps, before starting
  • Ask a lead or technical services if the data is unclear, rather than filling the gap yourself
4.Walk us through a borescope inspection you've done or trained on.

Why they ask

Borescope work on turbine engines is common after bird strikes, foreign object reports and scheduled checks. It tests hands-on skill and judgment about limits.

How to answer

  • Name the engine section, such as the high pressure compressor or combustor, and the access ports used
  • Describe setting up the scope, turning the engine core by hand or with the drive tool, and recording images
  • Explain measuring what you find and comparing it to the manual's damage limits
  • Say who reviews the images and how findings get written up
5.How do you make sure an airworthiness directive has actually been complied with?

Why they ask

ADs are mandatory, and a missed recurring one can ground a fleet or bring an enforcement action. Line technicians often perform the work that closes them.

How to answer

  • Work from the task card or engineering order that references the AD and its method of compliance
  • Follow the specific steps and inspection intervals in the approved data
  • Record the compliance in the logbook and the tracking system exactly as the program requires
  • Flag it immediately if the card doesn't match the aircraft's configuration

Part 2

6.What does the maintenance tracking system do in your work, and which ones have you used?

Why they ask

Airlines and repair stations run on software such as AMOS or TRAX. Someone comfortable in it closes cards cleanly and doesn't leave records holes.

How to answer

  • Name the system and what you did in it: open cards, record findings, order parts, sign steps
  • Explain how it links your entries to the aircraft's permanent records
  • Mention checking that parts you install match what's recorded, including serial numbers
  • If you haven't used one, say which paper process you followed and that you'll learn theirs
7.Tell us about a time you found damage or a defect that wasn't on your task card.

Why they ask

Findings outside the card are where airworthiness is really decided. They want proof you write things up instead of walking past them.

How to answer

  • Set the scene: the check, the aircraft area and what you saw
  • Say how you documented it and who you told
  • Explain how you checked it against limits in the manual or structural repair manual
  • Give the outcome, including any delay you caused and why it was right
8.Which items from the human factors dirty dozen have you seen cause trouble?

Why they ask

Most airline training programs teach the dirty dozen, a list of conditions like fatigue, pressure and complacency that lead to maintenance errors. It shows whether you think about your own error risk.

How to answer

  • Pick one or two you've actually seen, such as fatigue on nights or pressure near departure
  • Describe what happened or nearly happened
  • Explain the safeguard you use now, like stopping to reread the card or asking for a second check
9.How do you hand over an unfinished job at shift change?

Why they ask

Incomplete turnovers have caused real accidents. A clean handoff protects the aircraft and the next technician.

How to answer

  • Record exactly where you stopped on the card, including anything disconnected or not yet torqued
  • Tag open items on the aircraft itself
  • Talk face to face with the incoming technician, not just a note
  • Make sure the lead knows what's open
10.What's your experience with engine runs or taxiing aircraft?

Why they ask

Carriers qualify technicians for run-ups and taxi moves, and it's a sign of trust. They want to know what training you already have and how seriously you treat it.

How to answer

  • Say honestly which types you're qualified on, if any
  • Describe the checklist discipline, communication with ground control or the tower, and wing walker use
  • Mention what you'd do if an indication went out of limits during the run

Part 3

11.Why do you want to work for an airline or repair station instead of a small general aviation shop?

Why they ask

The pace, shifts and structure are different. They want to know you understand what you're signing up for.

How to answer

  • Name what draws you: larger aircraft, structured training, career steps into inspection or planning
  • Show you know about seniority, night shifts and working under a formal program
  • Connect it to something concrete from your school or past jobs

Questions to ask them

Ask at least two. It shows you're picking them too.

  • Which aircraft types are at this station, and what type training do new technicians get in their first months?
  • How does shift bidding work here, and how long do new hires usually stay on nights?
  • How are engine run and taxi qualifications handled, and when could I start working toward them?
  • What does the path from technician to inspector or lead look like at this base?
  • How does maintenance control support the line when a deferral or delay decision comes up overnight?
