Three days later on September 12, Scandinavian Airlines Flight 2748 from Copenhagen to Palanga had a similar problem with the landing gear, forcing the aircraft to land in Vilnius international airport ( Lithuania ). No passengers or crew were injured.  Immediately after this incident SAS grounded all 33 Q400 airliners in its fleet and, a few hours later, Bombardier recommended that all Q400s with more than 10,000 flights be grounded until further notice.  This affected about 60 aircraft, out of 140 Q400s then in service.
Dizziness is a general, non-specific term often used to describe a variety of associated symptoms, such as feeling faint, lightheaded, nauseous, weak, or unsteady. If your dizziness is creating the sense that you or your surroundings are spinning, then that is more accurately called vertigo.  Dizziness is a common reason for doctor visits and is certainly uncomfortable and/or annoying to experience, but it's unlikely to represent a serious, life-threatening condition. There are many ways to overcome dizziness at home, but be aware of the "red flags" that signal the need for medical intervention.
