The crash of Continental Express flight 2574 in 1991 (see also this question) was caused by faulty maintenance to the de-icing boot on the left horizontal stabilizer. This became detached in flight, leading to violent movements of the plane which caused the left wing to fail and the right wingtip to detach. Ultimately, the horizontal part of the T-tail detached and the plane crashed.
The NTSB report says (page 34, with essentially the same statement repeated on page 37):
The airplane then rolled to the right at a roll rate exceeding 160 degrees per second. The Safety Board believes that the lift produced by the intact right wing produced the extreme roll.
The report also says that the initial failure of the left stabilizer caused a 10–15° roll to the right, which makes sense: the loss of downforce from the stabilizer meant the left side of the plane was generating more net lift than the right. But how would the subsequent failure of the left wing produce a roll to the right? The natural assumption would be that, with the right wing generating lift and the left wing not, the plane would roll to the left.
Possibly relevant is that the left wing failed but didn't detach from the plane: the plane crashed right-way-up with the left wing folded under the fuselage and the inboard portion of the right wing.
