WASHINGTON (Reuters) - National Transportation Safety Board chair Jennifer Homendy said staff at the agency would like to complete its probe into the Jan. 5 Alaska Airlines Boeing 737 MAX 9 mid-air emergency by early next year.

"I think they would like to finish in 12 to 14 months" from the time of the incident, Homendy told Reuters late Wednesday, adding it depends on the NTSB getting the information it needs. The NTSB also needs to complete a safety culture survey of employees at Boeing's ( BA ) 737 MAX factory in Renton, Washington that it plans to begin soon.
