Rescuers combed a jungle swamp Wednesday for victims of a Peruvian airliner crash that killed at least 31 people, including one American, after the jet split in two during an emergency landing in a hailstorm.

Officials said 57 others escaped the burning wreckage, wading away through knee-deep mud. Ten people remain missing.

TANS Peru Flight 204 was the world's fifth major airline accident in August, making it the deadliest month for plane disasters in three years. At least 330 people died in crashes in Venezuela, Greece and off the coast of Sicily. All those aboard a plane landing in Toronto survived a runway accident.

The plane that crashed in Peru, a Boeing 737-200, was carrying 98 people on a flight from the Lima, the capital, to the Amazon city of Pucallpa. It crashed in Pucallpa, about 300 miles northeast of Lima.

In strong winds and torrential rains, the pilot circled the airport, then tried to make an emergency landing about 20 miles away. He aimed for the marsh to soften the impact, but the landing split the aircraft, said Edwin Vasquez, president of the Ucayali region.

Wind shear -- a sudden change in wind speed or direction -- possibly doomed the emergency landing, said TANS spokesman Jorge Belevan. He said there did not appear to have been a technical failure in the 22-year-old aircraft.

Police Lt. David Mori said 56 survivors were being treated at hospitals. Rescue efforts late Tuesday were suspended until Wednesday morning because of darkness and bad weather. Officials had said Tuesday night that 41 bodies had been recovered.

Among the dead were at least three foreigners -- an American woman, an Italian man and a Colombian woman, Mori said. Many bodies could not immediately be identified.

According to officials and radio reports, the plane circled the airport, then crash-landed near a highway after the pilot radioed that he could not land because of strong winds and torrential rains.

"I felt a strong impact and a light and fire," survivor Yuri Gonzalez told the broadcaster Radioprogramas. She said she thought she "was in the middle of flames around the cabin, until I saw to my left a hole to escape through."

Rescue workers and locals remove part of a jetliner that crashed in Peru's northern jungle. Officials said at least 31 people were killed; 10 remain missing.
