NTSB slaps American

Federal officials have banned American Airlines from an investigation into Wednesday’s runway overrun at Jackson Hole Airport after airline workers inappropriately accessed flight recorder information from the 757.

While en route to the National Transportation Safety Board’s recorder laboratory in Washington, D.C., American Airlines personnel diverted the digital flight information recorder and the cockpit voice recorder to Tulsa, Oklahoma, the NTSB announced Friday.

“During this incident investigation, the security Board learned that the recorders were flown to Tulsa, Oklahoma, where American Airlines technicians downloaded information from the [digital flight data recorder]; the [cockpit voice recorder] was not accessed by American,” NTSB officials told in a statement Friday.
