Turkish Airlines (Istanbul) Boeing 737-800 crash at Amsterdam on February 25, 2009 has already been blamed on a faulty altimeter. The Dutch authorities investigating the accident have issued the quick preliminary report in order to alert other Boeing 737 operators. Boeing has also advised 737 operators of the potential danger. At 1,950 feet (594 meters) the auto pilot, with the incorrect data coming from the faulty altimeter (it was showing an altitude of -8 feet), shut down the engines. The crew attempted to restart the engines but they were already too low to recover. Nine people died in the crash.
