Era Aviation has resumed some limited service in Alaska after the commuter airline grounded 12 airplanes over the weekend.
Airline spokesman Steve Smith says flights Monday morning were being routed by dispatchers to provide service to those most affected by the weekend grounding.
The planes were grounded after Federal Aviation Administration officers determined cockpit voice recorders were out-of-date and needed to be upgraded. Era says high winds also affected some flights in Southcentral Alaska.
Some passengers were put up in Anchorage hotels or on other carriers to continue their flights. Era serves a number of Alaska communities.
The federal investigation stems from an incident this month when an Era plane traveling from Anchorage to Homer dropped 5,000 feet before pilots regained control.
