(ABCNews) MANILA, Philippines — The wreckage of a small plane carrying two Filipino pilots and two Australian passengers was identified Tuesday on one of the Philippines’ most active volcanoes, officials said.

An aerial search found no sign of those aboard the Cessna 340, which crashed into a gully on the slope of Mayon volcano in Albay province, where it went missing after taking off Saturday enroute to Manila, aviation officials said.

“The condition of the crew and passengers are not yet known as the exact site has not yet been reached by the search and rescue team due to bad weather,” the Civil Aviation Authority of the Philippines said. It said investigators spotted the wreckage after three failed aerial searches Tuesday morning due to thick clouds.
