SANTA CLARA — For the second consecutive home game, an airplane flew over Levi’s Stadium carrying a banner condemning 49ers CEO Jed York.

“HOLD JED ACCOUNTABLE,” read Sunday’s banner, some two hours before kickoff against the Cincinnati Bengals.

Prior to the 49ers’ previous home game — on Nov. 29 against the Arizona Cardinals — frustrated fans sponsored a banner that read: “Jed & 49ers should mutually part ways.”

At a news conference last December, following the “mutual parting” with coach Jim Harbaugh, York invited the public to “hold me accountable.”

York has barely spoken publicly this season.

The 49ers (4-9) have clinched their first losing season since 2010, when they went 6-10.
