A fare-beating gunman has been busted for allegedly opening fire on a trio of MTA workers after they booted him from a bus in Brooklyn, cops said Thursday.

Samuel White, 49, was arrested Wednesday and charged with attempted murder, reckless endangerment and weapons charges, according to police.

White is accused of hiding behind a tree and firing off more than 10 rounds at three members of the MTA’s Eagle Team assigned to check that riders pay the fare on city buses.

Moments before White allegedly opened fire around 6:20 a.m. Tuesday, the inspectors kicked him off a B82 bus at the corner of Flatlands and Louisiana avenues in Canarsie for fare evasion .

One of the workers was grazed by a bullet, cops said.

White’s arraignment was expected Thursday.
