The plane's occupants, a 31-year-old woman and a 29-year-old man, walked under their own power to a waiting ambulance after being brought to Maunalua Bay Beach Park in Hawai'i Kai.

There were the only people aboard the plane, fire department officials said.

The plane radioed that it had an inflight emergency and ditched about 5:53 p.m., the Coast Guard said.

Ian Gregor, a spokesman for the FAA, said the plane was a Cessna 150 with two people aboard.

"The pilot declared an emergency due to engine problems before he ditched his plane," Gregor said. "The aircraft was destroyed."

Gregor also said, "An aircraft in the vicinity passing by reported seeing two people in a raft."

An emergency radio transmission said an orange life raft was in the water.

There was no flight plan filed, Gregor said.

The fire department and Coast Guard launched rescue crews, and the plane's occupants were picked up quickly from the raft a mile southeast of the China Wall area of Koko Head, the fire department said.

Both of the plane's occupants were able to get into a life raft, the Coast Guard said. The fire department's Air One helicopter brought the woman to shore, while the HFD boat picked the man up from the raft.

A yellow fire department helicopter dropped off the woman in the parking lot at Maunalua Bay Beach Park shortly before 6:30.

About 10 minutes later, a fire department rescue boat brought her husband to the park. They were taken to an ambulance but declined medical treatment, said Bryan Cheplic, spokesman for the city Department of Emergency Services.

The plane's emergency location transmitter has not emitted a signal and there is no sign of pollution or wreckage, the Coast Guard said.

A National Transportation Safety Board database shows just one previous Hawai'i incident involving a variant of the Cessna 150 since 2002.

No one was injured when a Cessna 152, a newer version of the Cessna 150, collided with trees during a forced landing caused by engine trouble near Hana on Maui.
