Still Can't Build Planes

Remember when Boeing spun off its Wichita facilities as Spirit in order to boost the profit numbers?

A classic example of unproductive financial engineering to hit the numbers, because that always works so well.

They may have to reacquire the firm because the quality situation is so dire.

Spirit Aerosystems delivered a bunch of rear pressure bulkheads where the holes were miss-drilled, and they just drilled new holes.

So some additional holes in the rear Pressure Bulkhead, and some of these new holes were, "Snowmen," where the holes overlap.

From now on, it's Airbus for me:

Boeing is reviewing a newly disclosed 737 Max production issue to determine if the problem might keep it from meeting its 2023 aircraft-delivery target.

The company on 23 August said a problem involving mis-drilled holes in 737 Max 8 aft-pressure bulkheads would impact its “near-term” deliveries.

………

The problem involves “fastener holes that did not conform to our specifications in the aft-pressure bulkhead on certain” 737s, Boeing said on 23 August. “This issue will impact near-term 737 deliveries as we conduct inspections to determine the number of airplanes affected, and complete required rework on those airplanes.”

Spirit says the defect involves “elongated” fasteners. It has implemented “changes to its manufacturing process to address this issue” and does not expect the problem to cause a “material impact to our delivery range for the year”. Also, multiple companies supply the affected parts to Spirit, which is why not all airframes are affected, it adds.

………

Also, in April, Boeing disclosed having halted some 737 deliveries due to “non-conforming’ fuselage components.

Boeing has outsourced its quality checks to its vendors, who are generally disinclined to report on themselves, because it boosts the quarterly numbers.

Corporate murder by MBA.
