You are assuming this is problem in the assembly and not in the design?

You are assuming this is problem in the assembly and not in the design?
- rpeden 3y agoThe same part was used on the 737-900 for quite a while and didn't (as far as we've heard, at least) have any similar issues there.
- dralley 3y agoAnd you seem to be assuming that the problem is in the design and not the assembly... The latter seems more likely.
- jacquesm 3y agoYou are both missing the 'faulty process' and 'faulty communications' options.
- local_crmdgeon 3y agoAnd: - "bad parts from vendor" - "bad programming on torque wrench from MRP" - "insufficient training on process" - "tooling was programmed correctly but bad sensors" - "lube mislabeled for 3 days" This is absolutely not some simple thing. This is why people don't take us seriously as engineers.
- adrian_b 3y agoFor loose bolts, incorrect assembly is by far the most likely cause. It can be a design problem if the bolts and associated parts like washers have been substituted recently or if the assembly instructions have been changed recently, e.g. by specifying a different torque. If any such engineering change has happened recently, then that would be the likely culprit. A resonance problem of the aircraft body as supposed by another poster seems extremely unlikely as that would have required significant recent changes to the aircraft body, which did not happen.
