Then change Delta to Atlantic Southeast. I have no idea who does their maintenance so risk painting them with the wrong brush, but imo there seems to be too much "shareholder value" being created by airlines saving money on maintenance.
Obviously the gear problem could have been due to damage in operation, or a material defect, or any number of other problems. One would hope the poster who said it was maintenance knew for a fact that the aircraft was fresh from maintenance that included the gear. It still could have been a defective part that the maintenance facility couldn't have detected, but history suggests that's the far less likely situation.
Again speaking generically, contract regional carriers are at the mercy of their biggest customer - the mainline carrier who lends them their paint job and flight numbers - and must be under enormous pressure to be frugal. Their flight crews work for pauper's wages an a dream of getting a job with a real airline, and it wouldn't take a huge leap to guess that the same budgetary pressures apply to maintenance. Which is always done to FAA standards, of course.
Sorry for the rant. Not. It's really important and doesn't seem to be trending the right direction.
