Oil filter
"But in the name of God, who could miss that big ol' oil filter bolted to the side of the transmission? Who could look at that and *not* think that there's even a remote chance of a leak developing there? Methinks that the FAA's Les Dorr is sweating a bit right now. Or at least squirming uncomfortably."
Hindsight is 20/20 most of the time. I've never had an oil filter leak so if you asked me what the risk was I'd have pointed to hoses, clamps, drains and every other point than the filter or it's mount. Granted, I'm just one old guy without all the input that the FAA or any other regulatory body gets, but how many oil filters have you ever heard of that caused a problem?... Unless the darn thing wasn't wired and locked....which isn't the problem in this case.
Fatal reality checks are a bitch.
