Los Angeles (CNN) An update from the National Transportation Safety Board into the January 26 helicopter crash that killed Kobe Bryant and eight other people in Southern California appears to point the investigation away from engine failure and toward the weather and the actions of the pilot, according to one aviation expert.

Friday's update covered several topics, such as the flight history of the pilot and of the Sikorsky S-76B, the weather on that morning and the interaction with air traffic controllers.

"These (updates) are usually a little bit of a road map of where the investigation is going to go," said CNN transportation expert Peter Goelz, a former managing director of the NTSB. "If there were concerns about the equipment or anything else, it would be mentioned.

"In this case, they focused in on the weather, they focused in on the pilot's interaction with air traffic control, and in the end I'm afraid the spotlight is going to be on the pilot and his decision-making."

The NTSB update focused on the facts of the case, including photographs, but did not include analysis. The board will release a determination on the cause of the crash in its final report months from now.
