A small airplane crashed into the water just off Ocean City on Sunday afternoon, authorities said.

The search was suspended just before 9 p.m. Sunday night due to dangerous conditions, the Maryland State Police said.

They cited darkness, a hazardous current and high waves.

They said no one from the plane had been located. However, divers from the police underwater recovery team believed that they had located the debris from the plane.

The crash was reported about 4 p.m. by people on the beach near 133rd Street, according to the Maryland state police. The plane went into the water about one half mile from the shore, the police said.

The Ocean City police were to maintain a presence on the beach near the crash site throughout the night, state police said.

The state police said the plane may be one that can carry one passenger along with the pilot, using tandem seats. It was not known if anyone but a pilot was on board.

They said police investigators believed the plane, driven by a single propeller, may be one designed originally as a trainer for the air force of the People’s Republic of China. It has reportedly became popular as a hobby plane in the United States.

Police asked witnesses, particularly those with pictures, to contact them at 410-641-3101.
