NTSB calls out aviation agency on medical helicopter safety

Vote came during a meeting to update a list of "most wanted" transportation safety improvements.

The National Transportation Safety Board on Tuesday ruled "unacceptable" the Federal Aviation Administration's progress on installing terrain awareness warning systems in emergency medical helicopters.

The board ruled on the measure by a 3-2 vote.

The vote came during the board's meeting on updating the "Most Wanted" transportation safety improvements.

"I'm frustrated as hell about it," said Acting Commissioner Mark Rosenker, "[but] we have to look at reality."

The board unanimously decided to add EMS aviation issues to the most wanted list.
