Transportation secretary Sean Duffy and acting Federal Aviation Administration (FAA) head Chris Rocheleau made the comments at a news conference and said they had seen videos of the crash in India.

Duffy said he had spoken to National Transportation Safety Board (NTSB) chair Jennifer Homendy. An NTSB and FAA team, with support from Boeing and engine manufacturer GE Aerospace, was going to India, Duffy said.

“They have to get on the ground and take a look. But again right now it’d be way too premature,” Duffy said. “People are looking at videos and trying to assess what happened, which is never a strong, smart way to make decisions on what took place.”

Duffy said the FAA was reviewing information with Boeing and GE as part of the investigation into the crash.

Duffy also emphasised the US government “will not hesitate to implement any safety recommendations that may arise. We will follow the facts and put safety first.”

Rocheleau said, “As we proceed down this road with the investigation itself, if there’s any information that becomes available to us regarding any risk, we will mitigate those risks.”

Duffy said the FAA is “prepared to send additional resources to get the data we need to ensure the safety of the flying public.”
