Aircrash investigation Season 7 Episode 3
Best of my knowledge.
On 8 September 1989, Partnair Flight 394 loses control, breaks up in mid-air, and crashes into the North Sea, killing all 55 people on board. The aircraft's vertical stabilizer had vibrated loose during flight due to excessive wear on sub-standard bolts, sleeves, and pins that had been illegally sold as "aircraft-grade."
