Fort Worth Meacham (FTW) Departure Procedures
Notice Number: NOTC0768
There have been several instances of aircraft deviating from
their ATC clearance when departing Fort Worth Meacham
airport (FTW) over the last few months. The pilots involved
have generally been experienced instrument pilots flying
technically advanced aircraft.
In these instances, all of the aircraft have been cleared to
fly runway heading for radar vectors to a published
departure procedure in their clearance from departure
control. Each of the aircraft has made an inappropriate turn
after takeoff either to join the course for the departure
they were assigned or in following a procedure that is
printed on the chart.

They had a rash of that at Riverside, CA a few years ago. (For all I know, it
is still a problem there.)
