Wheel flies off United Airlines plane during takeoff in Los Angeles

One pilot said the wheel rolled across two runways into a cargo area.

(KTLA) -- A United Airlines Boeing 757-200 jet lost a wheel during takeoff at Los Angeles International Airport on Monday, the airline confirmed.

United Flight 1001, which was carrying 174 passengers and seven crewmembers from LAX to Denver, departed shortly after 7 a.m.

“The wheel has been recovered in Los Angeles, and we are investigating what caused this event,” said United spokesperson Anousha Rasta, adding that no injuries were reported on the aircraft or the ground.

According to FlightAware, the jet landed safely in Denver at 10:51 a.m. local time.

The pilot of an Allegiant Airlines flight witnessed the incident and immediately reported it to air LAX traffic control.

"A tire came off that B-75 that took off. We saw it rolling down past bravo-seven, bravo-eight [holding positions]," the pilot said in a recording shared by VASAviation.

An air traffic controller notified the pilot of United Flight 1001, who appeared to be unaware the jet had lost a tire, the recording indicates. Another pilot said the wheel rolled across two runways into a cargo area.

This prompted air traffic control to divert a taxiing Air Canada flight so crews could conduct a runway inspection.

In March, a United Airlines Boeing B777-200 jet traveling from San Francisco to Osaka, Japan, lost a tire during takeoff and was forced to make an emergency landing in Los Angeles. The tire slammed into cars in an airport employee parking lot.

Boeing’s 757-200 has four wheels on each main landing gear and two on the nose gear.
