Does your company have an operational flight data analysis program?
Even for small operators with small fleets and aircraft with bread-and-butter parameter sets, a decent FDM/FDA/FOQA Program can be run, (provided it has been set up correctly and the data validated.)
A question:
Is this person unique in disregarding SOPs or is this a company-wide trend?
Either way, a flight data analysis program will be able to provide feedback on the daily operation so that these "violations" (Reason's definition etc., not regulatory), may be addressed.
I suspect that a company-wide trend will not welcome a flight data program but the proof is in the results. If such SOP violations are limited to one or two persons, there are other ways to address the matter. As always, such problems if chronic and not once-off's, almost always start at the top of the organization: What is tolerated as an operational standard by senior management is what will occur on the line.
Very often, and where the intent is to improve safety and not resort to ineffective methods such as blame, enforcement and discipline, a flight data program will provide the very basis for change because it provides data not opinions and does not countenance the usual psychological or organizational denial mentality that often those new to flight data analysis can sometimes have.
Good luck. If that is truly the way someone's operation is being routinely carried out, that is seriously disrespectful of one's professional integrity, one's colleagues, one's employer and one's passengers. History shows that it is an accident waiting to occur.
