Billionaire entrepreneur Elon Musk's&nbsp;company SpaceX has received a warning from the US&nbsp;Federal Aviation Administration (FAA) that its environmental review of a new tower at its Boca Chica launch site in Texas is incomplete.

The largest transportation agency of the US government could&nbsp;order SpaceX to take down the tower.

An FAA spokesman said on Wednesday that the agency's environmental review underway of SpaceX’s proposed rocket assembly "integration tower" is "underway," and added that "the company is building the tower at its own risk."

A letter from the FAA to SpaceX sent on May 6&nbsp;said recent construction activity on one of the two proposed towers "may complicate the ongoing environmental review process for the Starship/Super Heavy Launch Vehicle Program." The FAA letter said the tower could be as high as 480 feet.

Based on the environmental review, the FAA could order SpaceX to take down the tower.&nbsp;"It is possible that changes would have to be made at the launch site, including to the integration towers to mitigate significant impacts," the May 6 letter said, adding the FAA learned of the tower's construction "based on publicly available video footage."

SpaceX did not respond to a request for comment but Musk has repeatedly criticized the FAA and the US&nbsp;regulatory system.

SpaceX told the FAA in May that it did not believe the review was necessary because it only intends to use the "integration tower for production, research, and development purposes and not for FAA-licensed or -permitted launches," the FAA said.

But the agency said description in documents "indicates otherwise."

The FAA cited a SpaceX document that the towers would be used to integrate the Starship/Super Heavy launch vehicle. "Super Heavy would be mated to the launch mount, followed by Starship mated to Super Heavy," the FAA letter said quoting SpaceX's May 5 submission.

The FAA and Musk have clashed on several occasions.

On June 29, Musk lamented the delay of the launch of the Transporter-2 mission in Florida. He tweeted "an aircraft entered the ‘keep out zone’, which is unreasonably gigantic. There is simply no way that humanity can become a spacefaring civilization without major regulatory reform."

Earlier this year, the FAA said SpaceX's December launch of Starship SN8 violated its license requirements.

Effective March 12, the FAA began requiring an agency safety inspector at all SpaceX launches to "ensure compliance with federal regulations to protect public safety."

FAA Administrator Steve Dickson spoke with Musk on March 12 for 30 minutes to stress "the FAA’s role in protecting public safety by ensuring regulatory compliance. He made it clear that the FAA expected SpaceX to develop and foster a robust safety culture that stresses adherence to FAA rules," the agency said in April.

FAA warns SpaceX that massive Starship launch tower in Texas is unapproved

A meeting of international aviation officials due to be held in&nbsp;Singapore&nbsp;on the&nbsp;eve&nbsp;of Asia's largest annual aerospace&nbsp;event has been&nbsp;canceled&nbsp;because of&nbsp;coronavirus&nbsp;fears, participants said, raising doubts that the broader&nbsp;event will go ahead.

The UN&nbsp;International Civil Aviation Organization (<a href="https://www.wionews.com/india-news/india-has-rightly-complained-against-pakistan-to-icao-defence-experts-258517">ICAO</a>) and three industry sources confirmed on Monday that February.

10&nbsp;Singapore&nbsp;Airshow&nbsp;Aviation Leadership&nbsp;Summit&nbsp;had been abandoned.

The news adds to a series of pullouts by companies from the main&nbsp;Singapore&nbsp;Airshow, which is scheduled to begin on February 11, under the shadow of the fast-spreading virus.

Speakers at the Leadership&nbsp;Summit&nbsp;were due to include ICAO President Salvatore Sciacchitano, US&nbsp;Federal Aviation Administration (FAA) Administrator Steve&nbsp;Dickson and International Air Transport Association (<a href="https://www.wionews.com/world/airlines-globally-produced-67-million-tons-of-waste-each-year-iata-study-271872">IATA</a>) Director General Alexandre de Juniac.

Organisers said on Monday the broader show would go ahead, albeit with reduced attendance due to travel restrictions. Organisers of both the show and the&nbsp;summit&nbsp;could not immediately be reached for comment after an ICAO spokesman confirmed the&nbsp;summit&nbsp;cancellation.

Singapore&nbsp;has denied entry to all Chinese visitors and foreigners with a recent history of travel to China, where the virus originated.

Commercial Aircraft Corp of China (<a href="https://www.wionews.com/world/china-russia-developing-jet-to-compete-with-boeing-and-airbus-8304">COMAC</a>), which is developing the C919 narrowbody jet, along with nine other Chinese companies, would no longer be participating in the show, organisers said.

Other companies to announce their non-attendance in recent days include business jet manufacturers Bombardier Inc, Textron Inc and General Dynamics Corp's&nbsp;Gulfstream division.

"Out of an abundance of caution," Bombardier will not have any business jets on display at the show, a company spokeswoman told Reuters by email.

However, Boeing, Airbus and Lockheed Martin Corp among the biggest exhibitors said on Monday they still plan to attend the show.

The death toll from the&nbsp;coronavirus&nbsp;has risen to 361 in China, bringing the number of confirmed infections to 17,205. The flu-like virus, which can be transmitted from person to person, has spread to more than two dozen other nations and regions.

Experia&nbsp;Events, the organiser of the&nbsp;Singapore&nbsp;Airshow, said last week the show would continue as planned, but the government measures meant it would "undoubtedly see a reduction in terms of the number of expected exhibitors and visitors this year."

The organiser said there would be doctors and medics on standby to attend to visitors who were feeling unwell.

In 2018, there were 54,000 trade attendees from 147 countries and 1,062 participating companies who come to network, examine products and sign deals covering commercial aviation, defence, maintenance and repair operations, and business jets.

Typically, it is not a&nbsp;major&nbsp;show for commercial plane orders but talks during the show can set the stage for deals that are completed later in the year.

Bombardier, Textron and Gulfstream said their decision to not attend this year was a precautionary measure to protect the health of employees.

South Korea's air force said on Monday it had decided not to participate as part of broader precautions against the&nbsp;coronavirus. Its Black Eagles aerobatic team has taken part in the flying display at&nbsp;Singapore&nbsp;airshows in recent years.

Russian aerospace group Rostec plans to send a reduced delegation to the show, Russian media reported. Rostec did not respond immediately to a request for comment.

The FAA said Dickson, who had been scheduled to speak at the conference, still plans to go to&nbsp;Singapore&nbsp;as of now.

Dickson, however, canceled a trip this week to Brussels following a declaration on Friday of&nbsp;coronavirus&nbsp;as a health emergency of international concern, the FAA said in a statement.

The outbreak of the new virus has sent shivers through financial markets, with investors drawing comparisons to the 2003 outbreak of <a href="https://www.wionews.com/world/sars-like-virus-spreading-across-china-amid-140-new-cases-third-death-275342">Severe Acute Respiratory Syndrome</a> (SARS) that also started in China and killed 800 people globally.

Singapore, a Southeast Asian tourism hub where Chinese nationals make up the largest share of visitors, was among the worst-hit outside of China during the SARS outbreak.
