Don't know much about this airline, but it would appear as if they were recently in the news for maintenance issues:

The Colombian airline West Caribbean Airways temporarily suspended its operations after Colombian authorities grounded the MD-80 fleet of the airline reportedly because of non-compliance with an airworthiness directive. The AD ordered the operator to install fire retarding insulation material. (Diario la Republica)"
