N837UA accident at Houston, TX

The failure of the cabin crew to activate the evacuation alarm and to maintain coordinated communication with the flight crew following the cabin crew’s decision to command an evacuation, which resulted in an engine running during the initial evacuation. Contributing to evacuation difficulties were passenger noncompliance with cabin crew instructions, including retrieving carry-on baggage, ignoring instructions to remain seated and to return items to the overhead bins, and to wait for the L2 slide to fully deploy.
