(CNN) -- Boeing is asking pilots who fly its 737 jets to pay careful attention to flight instruments after Dutch investigators said a faulty altimeter contributed to the recent crash of a 737 in the Netherlands.
Turkish Airlines Flight 1951 broke into three pieces near Schiphol Airport on February 25.
The 737 is the most widely flown jet in commercial aviation. More than 6,000 have been sold, according to Boeing."
