Hornslet wind-turbine collapse

[citation needed] After a malfunction from a worn brake mechanism, a service team from Vestas were called.

Vestas engineers checked and repaired the wind turbine brake on the morning of 22 February 2008.

After repair and several checks of the brake, the turbine was restarted in order to bring it back into normal operation.

After its generator was synchronized to the grid a noise from the nacelle prompted an attempt to stop the turbine manually.

[citation needed] A large crashing sound occurred, possibly as a result of the gear failing, at which point the turbine began to oscillate strongly.
