Delta Air Lines announced one of its planes was towed to its gate upon arrival at Daniel K. Inouye International Airport today due to a potential mechanical issue after landing.

Flight 278, from Osaka, Japan, touched down on runway 8L in Honolulu at about 9 a.m. with 198 passengers onboard the Boeing 767 aircraft.

After landing safely, smoke was seen coming from one of the wheels or tires, said Federal Aviation Administration spokesman Ian Gregor in an email. Fire crews met the aircraft and it was towed to its gate at about 9:15 a.m., he said.

In a statement, Delta said the plane was towed “out of an abundance of caution due to a potential mechanical issue following landing.

“Customers deplaned without incident and maintenance technicians are reviewing the aircraft as customer safety remains Delta’s top priority,” the statement said.

The airline noted there was apparently a small hydraulic leak that dripped onto hot landing gear, causing the smoke.

The flight still made it to its gate ahead of its scheduled time, according to flightview.com.
