Faulty B737 Slat Tracks: FAA Proposal to Fine Boeing $US 3.7m

Mods: If this has already been covered in the multitude of threads and posts related to Boeing's apparent failures, then please feel free to delete. Otherwise, let's add this the unfortunately increasing list of Boeing's questionable self certifying practices. |

The agency said the weakened components could allow the slats "to depart and potentially strike the aircraft, resulting in injury to aircraft occupants and/or preventing continued safe flight and landing." |

Who am I to argue with the FAA, but my biggest worry here would be the asymmetrical lift effect of a leading edge device departing one side of the airplane.
But who in their right mind would put cad plating in contact with titanium especially with long known embrittlement issues. Titanium is a poor heat conductor and a very poor friction surface under best of conditions - but great for friction welding ! https://www.finishing.com/38/92.shtml |
It appears to me that the Boeing Executive management group has been operating without integrity for some time now. Have they run a broom through it since the Max debacle or has there just been one or two sacrificial lambs? |
For an entirely different reason having to do with a poor design of slat track and lever , on the first or second 767 flight, the LE slats jammed on on side. result was the landing at paine field was at a much higher speed than planned now when you lose the whole leading edge device (especially an outboard slat) and the one on the other wing is still attached, that’s something completely different. Again, who am I to argue with FAA, but personally I would be more worried about uncontrollable roll. |
Looking at it from a slightly different angle, $3.7mil is small change not only for Boeing but even for any of its executives. Punishment for this kind of violations must be MUCH stricter. How about $3.7 billion for each "desgn flaw"?

https://en.wikipedia.org/wiki/Metal-..._embrittlement https://www.faa.gov/documentLibrary/...r/AC_43-4B.pdf 3.2.5 Titanium. Titanium is prone to cause severe corrosion of adjacent parts through galvanic corrosion. Titanium parts may be galvanically isolated from adjacent parts through barrier coatings or films. Frequent inspection for degradation of these barrier films and inspection for corrosion of adjacent parts is recommended. Contact with zinc and cadmium-plated parts can promote cracking of the titanium. |
Boeing has shown that the release of one slat section does not cause excessive asymetric lift |

I suspect that some fairly senior Boeing manager decided to just keep the production line going, keep moving the fifty-two airframes a month out the door, and "we'll fix them in a few weeks / months when the new parts come in". KPIs met, bonuses paid: what's a little falsifying of documents between friends? Boeing fails the ethics test again Why didn't the FAA suspend the authorisations of the responsible parties for say six or twelve months, and put them on a Final Warning: any repetition and they will never again hold an FAA delegation / authorisation? FAA fails the spinelessness test again, I'm afraid |
FAA: Boeing Knowingly Installed Faulty 737 Parts 233 sets of slat tracks made in mid-2018 were effected, the regulator revealed in a civil penalty letter sent to the OEM last week. |
