lolzAs I was surfing on Dirt's website, they did a round-up of mountainbikers reaction to Brexit. Cris Ball posted on twitter, (and I'm paraphrasing a bit) "what do a pigs head and Britain have in common?" I thought that was pretty cheeky.... I'm sure he's gutted.
May I guess?
You're close. Magnetic chip detectors, how do they work? The chunk of shit is of a yet to be determined nature and origin. It is the biggest thing I've seen come out of an engine that still ran.May I guess?
Looks like some kind of injector with a chunk of shit stuck to it via mysterious forces such as magnets.
God forbid!You don't work on helicopters do you?
Well good on that, because the chip detectors in helicopters are more of a "you have 20 seconds to live" warning.God forbid!
My only experience on helicopters came from an emergency landing of a A-star with a chip light that came on near the FBO I was working at many moons ago. Chip detector looked like a metal cactus. A flatbed truck picked up the ship later that afternoon. /CoolstorybroWell good on that, because the chip detectors in helicopters are more of a "you have 20 seconds to live" warning.
So how do you go about chasing down the source of a chip or chips?You're close. Magnetic chip detectors, how do they work? The chunk of shit is of a yet to be determined nature and origin. It is the biggest thing I've seen come out of an engine that still ran...
Where is the carb? And how do you load the weed into it?
I think they just collect them as a hobby.So how do you go about chasing down the source of a chip or chips?
Broadly speaking, you don't. It's usually a case of "within limits", "allowable" with restrictions, or "unallowable", depending on a wide variety of factors, including, but not limited too, size, shape, ferrous or non, etc. In this case, the engine is brand new (17.8 hours total). GE has a quite lengthy procedure that I spent most of yesterday accomplishing that has us drain the oil, collect oil samples and send to analysis, replace filters, check the screens in the various sumps, run bejeesus out of engine, repeat twice more. In this case, we never actually found any more metal.So how do you go about chasing down the source of a chip or chips?
reminds me of when I visited Warsaw in 1992. Minus the bullet/shell holes.
It was apparently the longest-running photography studio in the world; just closed. It was in India.reminds me of when I visited Warsaw in 1992. Minus the bullet/shell holes.
I can certainly say I had some parts that went across my desk that had some pretty significant chunks of metal liberated from them. Granted they typically didn't come out in a single piece like that, more gradual erosion, but there were some significant damage. Then again all my parts were flowpath so they probably just blew downstream damaging stuff in their wake.Broadly speaking, you don't.

It's possible that what I found was some sort of assembly goober, but that will be determined by the good folks at the oil analysis place. They use black magic and voodoo to determine exactly what section of the engine debris comes from based what ever kind of metal the pieces are made out of. Which is neat, in theory, but the reality for us is that if any of it falls into any of the "unallowable" categories the whole engine has to come off, so where exactly inside the engine is coming apart is a fairly academic procedure.
Recently, we had another brand new airplane making metal in the right engine. It kept making metal pretty much every time we did the flush/filter procedure. Oil analysis came back and the only place that plane went was to SLC on a ferry permit to have the engine yarded off.
