We operate our Learjet 31A, and YES, wipe the struts upon return to base. It takes all of about 5 minutes and if you can't handle doing such a very small task for getting paid above industry average, hit the road... The next highest paying Learjet 31A position in the area starts its Captains out around 20K less/yr than what we start an F.O. out.
We've got a few good things to gripe about, but having to wipe the struts doesn't qualify...
I have spoken to many different maintenance and field reps. that verify this as a good practice. The department that the original poster was speaking of is Wal-Mart's. They've got issues like any other department, but having to wipe the struts ??? BFD...
Bottom line, it does make a difference and I'll bet there are at least 30 resumes in my briefcase of very qualified individuals that wouldn't mind in the least wiping the struts for a 20K raise, awesome 401K, and outstanding medical coverage while working 13-14 days/mo. with an average of about 2 RON's/mo.
