Feb. 14 (UPI) -- A United Airlines flight bound for Hawaii made an emergency landing Tuesday after a piece of the jet's engine cover was torn off in flight.
An hour before United Airlines Flight 1175 was set to land in Honolulu, the cover fell apart and passengers experienced 40 minutes of shaking before the aircraft touched down.
"United flight 1175 traveling to Honolulu from San Francisco landed safely after the pilots called for an emergency landing because of a loss of the engine cowling (the covering of the engine)," United said in a statement.
"The flight landed safely and all passengers deplaned normally at the gate."
Passenger Erik Haddad, tweeted, "that looks bad, plane and simple," when describing the missing engine cover.
"There was a loud bang ... and then the plane really started shaking," passenger Allison Sudiacal said to Hawaii News Now. "It was like rattling and the plane was kind of shaking like boom, boom, boom."
No one was injured and the plane landed at Daniel K. Inouye International Airport and taxied to the gate.
The jetliner carried 363 passengers and 10 crew members.
The Federal Aviation Administration and National Transportation Safety Board are investigating the incident.
