Automotive maintenance at the hangar. The little "hub cap" on the front right started getting lose. You can take the wheel off the car without removing it, but you have to remove it to change the tire on the rim. This "hub crap" is made of some cheesy pot metal which is held in place by three sheet metal screws. Well, the guys at the tire shop tend to strip out the threads because the metal is so crappy. So that is what had happened. I slathered the screws with thread locker and carefully tightened it. Here's hoping it lasts for a while.
