MRO work instructions for aerospace: traceable at every step
Digital MRO work instructions for aerospace: AR-guided maintenance tasks, full traceability per step and records that support EASA Part-145 requirements.
In short
MRO work instructions guide technicians through maintenance, repair and overhaul tasks on aircraft and components. Actarion turns maintenance data and internal procedures into guided digital steps with AR on the part. Every step is signed off with user, time and evidence, which supports traceability and the documentation requirements of EASA Part-145.
How it works on the shop floor
How do you start a pilot in aerospace MRO?
- 1
Pick one task card
that is complex, performed regularly and often leads to findings or rework, for example a recurring inspection or component change.
- 2
Involve quality and the accountable manager early,
so the digital record fits your approved Part-145 procedures.
- 3
Convert the source data
(AMM references, internal task cards, photos) into steps with AI, then have a certifying technician review every step.
- 4
Run in parallel
with the paper or existing system for a fixed period, so the digital record can be checked against the approved one.
- 5
Measure
turnaround time per task, findings per audit and time to sign-off for new technicians. Decide on scale-up with that data.
What challenges do MRO organizations face?
- A shortage of licensed engineers and long training paths.
- Complex tasks where one missed step has serious consequences.
- Paper task cards and stamps that are hard to trace and audit.
- Human factors: fatigue, interruptions and shift handovers.
Which regulations apply?
- EASA Part-145 (Annex II to Regulation (EU) No 1321/2014) sets requirements for approved maintenance organizations, including the use of current maintenance data, work recording and certificates of release to service.
- FAA 14 CFR Part 145 for repair stations under US oversight.
- AS9110 adds quality management requirements for aviation maintenance organizations.
- Human factors training is part of Part-145, and clear task instructions help reduce maintenance errors.
Digital task cards must fit your approved procedures (MOE) and your authority's acceptance.
Use cases in aerospace MRO
| Use case | What it supports | KPI |

Frequently asked questions
No. The OEM data remains the source. Actarion presents it in guided steps and records execution.
Yes. For critical steps we set up a mandatory check by a second, authorised person, with photo or measurement evidence. In the pilot we verify that this fits your Part-145 procedures.
Yes. Component and engine shops are a good starting point for a pilot.
