WASHINGTON (AP) -- Federal aviation officials say they are investigating 17 cases in which 11 air carriers did not comply with safety directives.
An inquiry earlier this year found seven instances in which four carriers had not complied with directives issued by the Federal Aviation Administration.
FAA officials declined to identify the carriers and said they did not know if some of the new cases involve carriers already under investigation.
The inquiries were announced Friday by FAA administrator Robert Sturgell, who said 98 percent of the 5,600 safety directives audited by the agency had been followed by the carriers.
Earlier this year, audits of maintenance records were ordered for all domestic airlines following reports of missed safety inspections at Southwest Airlines.
