Several survivors of the Turkish Airlines crash at Amsterdam’s Schiphol airport in February are to sue Boeing in the US, law firm AKD Prinsen van Wijmen said on Monday.

According to news agency Reuters, victims are to demand up to $20m.
In total, nine people were killed when a morning flight from Istanbul crashed while approaching the airport. Air traffic investigators say a fault in an altitude gauge shut down the engine of the Boeing 737-800, causing it to drop out of the sky.
Boeing issued a reminder to all 737 operators to ‘carefully monitor primary flight instruments during critical phases of flight’ after the crash. But there are claims Boeing already knew there were problems with equipment measuring the altitude of 737-800s.
The law office said 10 survivors of the crash have agreed to ask Clifford Law Offices to start proceedings in the United States against Boeing. The case could be lodged in two to six weeks.
Other lawyers in the United States are also preparing cases against Boeing.
Settlement
Boeing has so far refused to consider a settlement, the Dutch law firm said on its website.
It is not clear what nationality the survivors planning to sue Boeing are. Earlier this year the AD said judges in the US must first rule that Dutch nationals can sue in their courts. Several US nationals were also on board the plane.
Last year, Dutch patients who used the painkiller Vioxx were told to sue in their own country.
