Mcdonnell Douglas DC-9-32 accident near Minneapolis, Minnesota, September 22, 2002
On September 22, 2002 at about 11:52 pm local time, a Mcdonnell Douglas DC-9-32, registered N941N, was substantially damaged in an accident near Minneapolis, Minnesota (Minneapolis-St Paul Intl/Wold- airport). It was flown under scheduled airline rules (Part 121). No one was hurt; 85 people were on board or involved. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The fatigue failure of the main landing gear strut due to inclusions in the material, residual stresses, and dissolved hydrogen content.

The NTSB's narrative final · quoted from the NTSB record
The airplane was damaged when the right main landing gear failed and collapsed during taxi for takeoff. A dark spot observed on the fracture surface showed a region with intergranular fracture features at the origin of the fracture with other areas of fatigue and intergranular fracture. Outside of the dark spot, the fracture features were consistent with overstress. Examination of the fractured landing gear revealed that small subsurface inclusions were present in the area near the fracture origin. Dissolved hydrogen content testing revealed hydrogen content ranging from 1 to 5 ppm. Residual stress tests show that the cylinder had compressive stress layers at the outer surface consistent with shot peening. The stress profiles showed maximum compressive stresses of 200 to 250 ksi transitioning to residual tensile stresses between 0.01 and 0.02 inch below the surface.
