The Evolving Role: How Digitalization Impacts Part-66 Technicians and Engineers
We have investigated how codified knowledge is transforming
Continuing Airworthiness Management Organizations (CAMOs) and reshaping the
hangar floor within Approved Maintenance Organizations (AMOs). Now, it's time
to bring the focus home: to the individuals at the centre of it all. What does
this digital revolution truly mean for the Part-66 certified maintenance
engineers and technicians who form the backbone of the industry?
For those with a few decades in the trade, the evolution is
undeniable. You’ve seen the shift from paper manuals and physical logs to the
early days of electronic records. For those just starting their careers, this
digital environment is simply the norm. Regardless of where you stand, this is
not a static moment; it's a profound reshaping of the Part-66 professional’s
role, where the core of your expertise remains crucial, but the methods of
applying it are changing fundamentally.

Beyond the Wrench: The Part-66 Holder’s Shifting Focus
Digitalization does not diminish the need for hands-on
expertise; rather, it elevates it. The time that was once spent on manual,
administrative tasks is now freed up for higher-value activities. The
traditional role is expanding to include new dimensions:
- From
Data Recorder to Data Interpreter: The days of meticulously
transcribing data from a component inspection into a paper log are fading.
Modern maintenance engineers and technicians now work with digital logs
and integrated systems. Their key contribution shifts from simply
recording data to interpreting the vast stream of information provided by
aircraft sensors and digital diagnostics. Their experience becomes the
ultimate filter, a human layer of judgment to validate what the system is
telling them.
- From
Reactive Fixer to Proactive Strategist: With the advent of predictive
maintenance, the role moves beyond fixing a fault after it has occurred.
Instead, the modern Part-66 holder uses data to anticipate component
failures, plan maintenance proactively, and optimize aircraft
availability. Their work becomes less about reacting to a fault code and
more about understanding the underlying trend and preventing the issue
from ever occurring. This is most noticeable in the line maintenance
environment and in Maintenance Control (MCC).
- From
Individual Practitioner to Collaborative Specialist: The digital
environment fosters a more collaborative approach. Integrated systems
break down the communication silos that once existed between the hangar
floor, the planning office, and the supply chain. This means maintenance
engineers and technicians can collaborate more effectively with their
peers, providing real-time feedback and sharing insights that improve the
entire operation.
The New Toolbox: Skills for a Digital-First Career
Just as a master craftsman acquires new tools over a career,
the modern Part-66 holder must acquire a new set of skills to complement their
deep mechanical and electrical knowledge.
- Digital
Literacy and Platform Proficiency: At a minimum, every professional in
the field must be comfortable with the digital platforms and software used
for maintenance management, data access, and regulatory compliance. The
skill to retrieve and enter information accurately into a Computerized
Maintenance Management System (CMMS) is as essential today as the skill to
properly torque a bolt.
- Data
Interpretation and Analytics: The ability to look at a trend line from
sensor data and identify a potential issue before a fault code is
triggered is a valuable skill set. Understanding how to use analytics
tools to make better-informed decisions is no longer just for management
or engineering; it's becoming a part of the frontline Part-66 professional's
domain.
- Specialized
Digital Competencies: The industry's evolution demands more than just
general knowledge. Proficiency with modern ERP and MRO systems, for
example, requires specialized training and proficiency to ensure data is
entered, retrieved, and managed accurately. These software platforms are
the new digital workbench, and a thorough understanding of their
functionality is now a key skill.
- Critical
Thinking and Problem-Solving: With automated systems, the role often
becomes about troubleshooting the exceptions. When a system flags a false
positive or fails to identify a clear problem, the professional’s
experience and critical thinking are what truly matters. This ability to think
beyond what the screen is showing you is, in my view, the ultimate
expression of professional expertise.
The Invaluable Constant: Human Expertise
Despite the profound changes, the core value of a Part-66
license holder remains steadfast: their human expertise. The digital tools and
platforms are just that, tools. They are powerful, but they require a skilled
professional to operate them, to interpret their outputs, and to provide the
critical judgment that a machine cannot.
The experienced maintenance engineer or technician, with a
career's worth of hands-on distinction, is now tasked with formalizing that
knowledge. They are the ones who can teach the digital systems what a subtle
noise, a specific vibration, or a particular wear pattern means. The newer
professional, meanwhile, is in a unique position to leverage this codified
wisdom to accelerate their own learning and drive innovation forward. This is a
mutually beneficial collaboration, where the experience of the past powers the
technology of the future.
Navigating the Path Forward
The impact of digitalization on the Part-66 professional is
not a threat to the trade; it is an evolution. It presents a clear path to a
career that is more engaging, more proactive, and more aligned with the
technological advancements that are defining the future of aviation. The
transition requires a commitment from both individuals and organizations to
embrace reskilling and continuous learning.
In our next discussion, we will investigate this topic
further, exploring the essential new skill sets for Part-66 holders in detail,
and how a proactive approach to professional development can ensure relevance
in the digital age.
Post Recap: Key Takeaways
- Role
Transformation: The Part-66 role is evolving beyond manual skilled labour to
include new responsibilities like data interpretation, proactive planning,
and collaborative problem-solving.
- New
Required Skills: Digital literacy, data analytics, and specialized
technical competencies are becoming as crucial as traditional mechanical
skills.
- Human
Expertise is Key: Digital tools require human judgment to be
effective; the experience of Part-66 holders is invaluable for validating
system outputs and troubleshooting complex exceptions.
- Collaboration: A "passing of the baton" is occurring, with experienced professionals formalizing their knowledge for new entrants, who in turn drive digital adoption.
