Engineering should clean more often
Maybe because it's not an Engineering function
That's not a get out, but a fact, in this day and age of budgets and costs it was deemed a few (or more) years back when we had to save 5% a year for 3 years, the question was raised why is cleaning being billed to Engineering? Just like plastic waste bags were! So it was removed as an Engineering function/cost. Who is now resonsible for it not sure, airports maybe.
Most outports that have cleaning contracts have fairly low paid people operating a vacuum cleaner, on average from what I have seen they may spend upto a minute in the flt deck. Not all of that will be actually cleaning, people in the way (tight turnaround times) etc.
if the air filter systems on these jets get cleaned as they should......
All filters will be replaced at specified intervals, maybe every A check or x amount of hrs/days or when there's a failure whichever comes first.
Put it in the tech log and it will have to get done!
Or ADD'd most likely.
