Search and rescue teams have found the flight recorder for a Trigana Air passenger aircraft that crashed in eastern Indonesia, killing all 54 on board, according to officials.

“At 1:40 local time the Trigana Air black box was found,” Transportation Ministry official Julius Arivada Barata told the Reuters news agency by text message on Tuesday.

Major-General Heronimus Guru, operations director at Indonesia’s National Search and Rescue Agency, told a news conference in the capital, Jakarta, on the same day that all passengers on the plane were dead and their remains were being put into body bags and recovered.

Officials have declined to comment on the cause of Sunday’s crash until the results of an investigation by the national transport safety committee, but Guru said the terrain in Indonesia’s easternmost province may have been a factor.

“There’s a possibility the aircraft hit a peak and then fell into a ravine because the place that it was found is steep,” Guru said.

Earlier, the National Search and Rescue Agency said the twin turboprop ATR-42-300 probably hit a peak on Sunday before crashing into a ravine in the Bintang Mountains district, about seven nautical miles from Oksibil.

ATR is a joint venture between Airbus and Alenia Aermacchi, a subsidiary of Italian aerospace firm Finmeccanica.

Plane was carrying money

There were 44 adult passengers, five children and infants and five crew on the short-haul flight from provincial capital Jayapura south to Oksibil town.

The aircraft was also carrying about $470,000 destined for remote villages, as part of an assistance programme. There was no suggestion the money was somehow linked to the crash.

Officials from Trigana were not immediately available to respond to questions from Reuters. The airliner has been placed on a European Union list of banned carriers since 2007 over safety or regulatory concerns.

All on board were Indonesian, officials said.

The aircraft made its first flight 27 years ago, the Aviation Safety Network says. Trigana Air Service has a fleet of 14 aircraft, aged 26.6 years on average, according to the airfleets.net database.

Trigana has had 14 serious incidents since it began operations in 1991, online database Aviation Safety Network says. Besides the latest crash, it has written off 10 aircraft.

Indonesia has a patchy aviation record, with other two major crashes in the past year.

In December, an AirAsia flight went down in the Java Sea, killing all 162 aboard. More than 100 people died in June in a crash of a military transport plane.

An Indonesian passenger plane that crashed at the weekend in Papua was transporting about 6.5 billion rupiah ($470,000) in cash to distribute to poor families in the eastern province, a post office official has said.

“Four of our personnel were escorting the funds,” said Haryono, the head of Jayapura post office, who goes by one name. The money was in four bags, he added, according to the AFP news agency.

An Indonesian search and rescue plane spotted debris believed to be from the aircraft that went missing on Sunday with 54 people on board in Papua province.

The wreckage thought to be from the Trigana Air Service plane was sighted on Monday morning in the heavily-forested Bintang Mountains region, local police chief Yunus Wally said.

Al Jazeera’s Step Vaessen, reporting from Jakarta, said a rescue plane had identified smoking wreckage and another smaller plane was on its way to get a closer look.

“At the same time two teams have gone overland but it’s a very mountainous area and they’re not sure how long this journey is going to take to get there,” our correspondent said.

A helicopter may also be sent – depending on what the smaller plane finds – to see if it is possible to land near the crash site.

The Trigana Air Service ATR 42-300 plane’s disappearance is the latest in a string of aviation disasters in Southeast Asia.

The passengers on the plane, reported to be an ATR-42 model, include 44 adults, two children, three toddlers and five crew members.

Hours after the plane’s disappearance, villagers in eastern Indonesia’s Papua region claimed to have found the wreckage, the transport ministry’s director-general of air transportation, Suprasetyo, who goes by one name, said.

“The plane has been found [by villagers]. According to residents, the flight had crashed into a mountain. Verification is still in process,” Suprasetyo said.

According a tweet by Indonesia’s National Agency Search and Rescue agency, the aircraft lost contact while flying over the remote eastern Papua region at 2:55pm local time.

The plane had been scheduled to land at a small airport in Oksibil around 3pm local time (06.00 GMT).

Oksibil is a remote town near the country’s border with Papua New Guinea.

Our correspondent said reports indicated that “the weather was very bad” in Papua at the time the plane was in the air.

“It is also known as quite a spooky area to fly in and planes go missing there.”

On Wednesday, a Cessna propeller plane operated by Indonesian company Komala Air crashed in Papua’s Yahukimo district, killing one person and seriously injuring the five others on board.

Officials suspect that the crash was caused by bad weather.
