Two Los Angeles Police Department officers sustained minor injuries in a helicopter training accident on Tuesday.

The LAPD aircraft was conducting a training exercise out of the Los Alamitos facility, located in the 4000 block of Doolittle Avenue, at about 1 p.m. when it "experienced a mechanical failure," said Officer Terzes.

The chopper made a hard landing with two aboard, though both officers were only minorly injured and were not taken to the hospital.

The Federal Aviation Administration is investigating the incident.
