Yes, I was being a bit facetious there. The maintenance paperwork (if any) will tell the real tale. Perhaps the flight school was unaware the gauge installation was not proper, and whoever performed the replacement had improper paperwork, or simply misunderstood the regulations. The world may never know.
If that were the case the owner/operator would have been afforded the opportunity to return the aircraft to service using the correct parts and the worse outcome would have been a letter of correction or counseling.
For this case to have made it to the stage of the owner/operator being fined tells us the owner/operator wasn't being cooperative which in turn forced this into an enforcement case.
Compliance Program
Our objective is to identify safety issues that underlie deviations from standards and correct them as effectively, quickly, and efficiently as possible. Our approach to compliance stresses a collaborative problem-solving approach (i.e., engagement, root-cause analysis, transparency, and information exchange) where the goal is to enhance the safety performance of individuals and organizations. An open and transparent exchange of information requires mutual cooperation and trust that can be challenging to achieve in a traditional, enforcement-focused regulatory model.
The FAA's approach to compliance furthers the evolution toward a "just culture." The concept of a "just culture" is one that has both an expectation of, and an appreciation for, self-disclosure of errors. A "just culture" allows for due consideration of honest mistakes, especially in a complex environment like the National Airspace System (NAS). But even unintentional errors can have a serious adverse impact on safety, so we must ensure that the underlying safety concern is fixed every time.
In October of 2018, the FAA renamed the Compliance Philosophy to the Compliance Program to reflect the advanced integration of these concepts into the fabric of the Agency's mission. The underlying principals and oversight processes that form the foundation of FAA's approach to compliance have not changed under this new title. The FAA's updated approach to compliance has been in effect since 2015 and has become a stable and integral part of our risk management strategy.
The FAA expects compliance to be the standard. Our evolved approach to oversight does not suggest that we are going easy on compliance. The FAA will continue to use legal enforcement actions (such as certificate suspensions and civil penalties) when needed. These actions remain an option for those who will not or cannot comply, and in cases where legal enforcement is required by law. Additionally, FAA will maintain strict accountability for inappropriate risk-taking behaviors and will have zero tolerance for intentional or reckless behavior.
Under the Compliance Program, the goal is to achieve rapid compliance, to eliminate a safety risk or deviation, and to ensure positive and permanent changes. As such, while legal enforcement action will be used when necessary, it is not the only means to address noncompliance.
In some cases, a Compliance Action is not an option, especially in cases where FAA personnel are required by law to proceed with enforcement.
