MAINTENANCE MINUTE By Mark Tyler ENVIRONMENT MATTERS — PART 1


When we talk about safety in aircraft maintenance, we usually talk about training, procedures, tooling, documentation and experience. All of those matter, but there is another factor influencing every maintenance task we perform—the environment in which the work takes place.


I’m not talking only about the hangar.


Over more than four decades in aircraft maintenance, I have learned that the environment surrounding a mechanic can either support good decision-making or quietly work against it. When we think about our environment this way, several different components begin to emerge.


The Shop/Hangar Environment


This is the environment most of us recognize immediately: lighting, temperature, cleanliness, organization, tooling, foreign-object debris (FOD) control, and workspace.


Poor lighting can hide a defect. Excessive heat or cold can contribute to fatigue. A cluttered work area creates distraction. Missing or poorly controlled tooling creates unnecessary risk.


These may seem like small things, but small things matter in aircraft maintenance.


The physical condition of the shop also communicates something about the standards of the organization. Walk into a clean, organized and professional maintenance facility and you immediately develop an expectation about the quality of work being performed there.


The opposite is also true. The Leadership Environment


There is another environment that may be even more influential—the one created by leadership. Does management communicate, intentionally or unintentionally, that schedule matters more than workmanship?


Imagine a mechanic discovering an unexpected discrepancy late in a job. The aircraft is scheduled to leave that afternoon.


What happens next?


Does leadership say, “Good catch; let’s get it corrected,” or does everyone groan because the aircraft was supposed to leave today?


That reaction matters.


Without saying a word about standards, we have just taught that mechanic something about what the organization really values.


Every reaction, every decision and every response from leadership contributes to the environment in which our technicians work.


The Cultural Environment


Culture takes this even further. What happens when someone makes a mistake?


Are mistakes reported so the organization can learn from them, or are they hidden because people fear the consequences?


Do experienced mechanics teach younger mechanics?


Is asking another technician for a second set of eyes considered professionalism—or weakness?

About the author: Mark Tyler dedicated the majority of his career to serving the helicopter EMS community,


from base mechanic to


director of maintenance. As vice president and general manager of Precision Aircraft Services, Tyler now serves helicopter operators from many sectors, including air ambulance, law enforcement, private owners, etc. When not at work, he can be found spending time with his family or sitting in a tree stand.


In Part 2, we’ll look at perhaps the most overlooked environment—the environment that exists inside the mechanic’s mind. Interruptions, pressure, fatigue, frustration and distraction don’t stay outside the aircraft.


Environment matters.


Are maintenance manuals actually used, or does experience eventually become an excuse for working from memory?


These questions reveal the true culture of a maintenance organization.


Policies may tell employees what the company expects, BUT culture teaches them what the company accepts.


What we repeatedly accept eventually becomes our standard.


The environment surrounding an aircraft mechanic is never neutral. It is either helping that technician perform at a higher level or making the job more difficult.
