MORGAN HILL — A small plane suffering engine failure made an emergency landing in the grassy median of northbound Highway 101 just south of Tennant Avenue on Sunday morning, authorities said.

Only the pilot had been on board, and he escaped injury, CHP said. No vehicles were struck by the aircraft, according to police.

The plane landed on the freeway around 11 a.m., CHP said. The Federal Aviation Administration cited engine failure as the reason for the emergency freeway landing. The plane was undamaged, FAA spokesman Ian Gregor said.

The six-seat, single-engine Piper propeller plane is registered to G&M Leasing LLC in Watsonville.
