The NTSB is asking the FAA to require more frequent inspections of aileron linkages on Bombardier regional jets after its investigation of a 2003 incident in which the crew briefly lost control of an RJ and had to make an emergency landing. The NTSB looked at 79 aircraft similar to the CL-600-2B19 in the incident and found that 19 percent of the planes had too much slop in their aileron linkages. The FAA currently requires inspections every 4,000 hours.
