Since someone posted the deepwater horizon. Its probably appropriate to post this: http://en.wikipedia.org/wiki/Ocean_Ranger At the time the largest oil paltform in the world. Sank in a storm in February 1982 on the grand banks off Newfoundland with no survivors. It is said that a port hole in the ballast control room was smashed, causing the computers to malfuction, later on, the rig develpoed a list, unable to be corrected by the waterlogged computers and eventually it flipped bow first and later sank. There were alleged to be a lot of problems with the rig. A week before the rig sank it developed a list, which obviously needed to be corrected. Some people who worked on the rig nick named it the "Ocean Danger" The radio operator was using an "oil company frequency" when sending distress calls rather than using a regualr distress frequency to alert the coast gaurd etc. Due to some sort of atmospheric condition, the emergency communications were also received by an oil rig in Tuktoyaktuk North West Territories. The wreck of the Ocean Ranger was only 32 metres below the surface of the ocean, and posed a hazard to large ships. On Aug. 22, 1983, the wreck was refloated and towed upside down out to deeper water where it remains to this day. Three divers were killed in the effort to refloat the sunken rig. Also this from the CBC archives, its long but quite interesting: http://archives.cbc.ca/environment/extreme_weather/topics/349/

You just have to get rid of the bad juju with some wolf's hair and the tears of a virgin. Anyway, I wish I had taken pictures of it, but when I was working at an independent shop a couple years ago a guy came in with a Pontiac Vibe that was "leaking". He threw a rod out the side of the block. Why? He bought it new and proceded to put 20,000 miles on the factory oil and filter. So we put in a used Matrix engine. Guess what happened 20,000 miles later. Except it was #3 instead of #2 that time.

I've since gotten the right-side head off completely except for one blind bolt in the back strapped to a cable harness that I just can't get leverage to break loose; I'll probably just cut the damned harness bracket tomorrow and replace it with some wire when I reassemble. I haven't hit the left side head bolts yet, but they should be pretty straightforward- plenty of clearance for a breaker bar. One last exhaust manifold bolt has thus far defeated me, though, it's the last thing between me and a brand new headgasket. I'm hoping inspiration will strike me tonight on some way to get it loose. Slack3r posted:Just undo the flanges at the "donuts" and pull the manifolds with the heads. Been doing that for years now. Much nicer pulling 4-6 fairly reachable bolts with real tools than undoing a bunch of hard to reach seized exhaust/head bolts. grover fucked around with this message at 02:36 on Jun 1, 2010 |

Not to horrible, but it is a stripped main gear on a mazda M50D five speed Click here for the full 1024x768 image. It came out of a '91 ford explorer with the 4.0L v6. It went out when when diving down the highway (it was pulling a '96 ford taurus wagon). Started making grinding noises and then power loss and a little while later just terrible grinding noises. When I pulled it apart there was still oil in it, however it is possible that some leaked out because the explorer spent about two hours on it's side a couple days before.

It starts when the spring perch starts pulling off, as it does so it rips the frame, weakening it until it fails completely. Looks like he's been driving it like that for a while. Not sure where you are located, but I'd look for something like this: http://stlouis.craigslist.org/cto/1749810109.html The bodies actually come off pretty drat easy. Bulkhead connectors, shifters, steering column, brake lines, fuel line, radiator hoses and six body mounts. That's pretty much it if you can lift it.

Last Sunday, Boeing ran into a problem with the 747-8 flight test program. The problem in this case being a 20-ton aircraft tug: No one was hurt and the engine itself was undamaged, but it's still going to be a rather expensive fix, both in terms of money and time (which is in short supply on the 747-8 program).

I still don't understand how the driver towing the 748 didn't see that tug sitting there. Guess they don't bother using wingwalkers. At least it's just the nacelle and not the fan or any of the internals.

What I was curious about though is if anyone actually had the numbers on the cost to say repair a turbine on one of those planes. I could imagine even the sheetmetal on that thing is expensive as hell to be flight rated.

All of those maintenance costs are buried miles deep in "leasing agreements". I'm sure somewhere, someone at GE knows what it actually costs to repair an engine if the front fan gets damaged...not that they'll ever let anyone outside the company know because they make so much money on the upkeep. Alternatively, in keeping with the spirit of the Aeronautical Insanity thread, "Put a

Hard numbers are hard to come by, but I've seen some ballpark estimates on the GEnx engine and its component cost: -Unit cost per GEnx engine is roughly $15 million per engine; -Each fan blade (there are 18 per engine) is about $200,000; -The damaged engine cowling seen in those pictures is about half a million dollars to replace. maxallen posted:I would think with that much damage on the engine housing there's a significant danger of... anything going wrong with that jet engine. At that point what do they do? Scrap it or does GE rebuild it? Like the GE90, the GEnx engine can be broken into two modules - the core engine (where the actual combustion occurs) and the propulsor (the fan section). If the fan case was damaged, they'd swap the damaged engine off the wing and install a new engine, then replace the propulsor unit on the damaged engine. while it's still a big job, a team of mechanics could have the swap done overnight if need be. Incidentally, the damaged aircraft has been repaired and flew again yesterday. MrChips fucked around with this message at 20:14 on Jun 8, 2010 |

It still doesn't look good for Boeing. They can't get their engine test off the ground because "WHO PARKED THIS HERE!" Someone, somewhere, in that entire operation had to have had the responsibility to clear the taxi way. It's rather silly that they couldn't get that right.
