AirAsia plane engine cuts out minutes before takeoff in Indonesia – report . . .

In the latest in a string of incidents, an engine of an AirAsia aircraft with 120 passengers onboard cut out during taxiing before takeoff from Juanda International Airport in the Indonesian city of Surabaya, and passengers were forced to disembark.

The plane, scheduled to fly to Bandung, also on Java, at 9pm local time Saturday, was taxiing for a couple of minutes when suddenly one of its engines cut out with a loud noise, Indonesia's Metro TV reported.

“The plane was ready and moved, but suddenly a loud sound was heard, the sound of the engine disappeared and the plane moved backward. We were shocked and panicked. The plane was then pulled back to where it parked and we were asked by the stewardess to leave the plane,” passenger Yusuf Fitriadi was quoted as saying.

Some time later, a man in a pilot’s uniform came out to the passengers waiting at the terminal and told them that the plane’s starter monitor had malfunctioned.

Fitriadi told Metro TV that when the airline announced later that the flight would be resumed once the malfunction was repaired, some 90 percent of the passengers refused to get back on the plane.

Those passengers who declined to take the flight were refunded in full by the airline, the report said.

There were three more minor incidents with AirAsia flights last week, on December 28 and 30.

In a separate incident later Sunday, AirAsia flight AK6242, with over 150 passengers aboard, experienced a technical problem about 10 minutes after taking off from Penang, Malaysia, and had to return to the airport. The malfunction was soon corrected and the flight safely reached its short-haul destination of Langkawi Island.

An AirAsia Zest plane from Manila on December 30 rolled off the runway in bad weather conditions on arrival at the popular Philippines resort island of Boracay. All 153 passengers and crew of the Flight Z2272 were safely evacuated from the aircraft at Kalibo airport, but the small airport was shut down for some time.

AirAsia’s flight QZ8501, which crashed last Sunday, also took off from the Surabaya airport.

Bound for Singapore, flight QZ8501 crashed in the Java Sea. All 162 passengers and crew of the A320-200 are believed to be dead, and large pieces of debris have already been found on the seabed off the coast of Borneo Island. The bodies of up to 30 passengers have been recovered from the water.

Four ‘big’ parts of AirAsia QZ8501 plane found – Indonesian officials

Search teams have discovered four large parts of AirAsia QZ8501, and 30 bodies of victims have been recovered, Indonesian search officials said. The plane crashed Sunday into the Java Sea with 162 people onboard.

Earlier in the day, Indonesian search and rescue said that they had discovered two parts of the plane.

"With the discovery of an oil spill and two big parts of the aircraft, I can assure you these are the parts of the AirAsia plane we have been looking for," search and rescue chief Bambang Soelistyo told journalists.

The larger of the objects is 10 meters by five meters, and both are at a depth of about 30 meters, he said.

Mayat 12 orang telah meninggalkan Pangkalan Bun untuk Surabaya: lapan diterbangkan pada hari Sabtu, empat pada hari Jumaat. Sembilan daripada badan-badan adalah lelaki, tiga perempuan.

Sejumlah 60 kapal dan 20 pesawat mengambil bahagian dalam operasi, dengan carian yang sedang ditumpukan kepada 1,575 batu nautika persegi, AFP melaporkan.

However, a strong current is now hampering recovery efforts, he added.

Over the past few days, rough weather had made search operations difficult, but 30 bodies of victims have been recovered.

The bodies of 12 people were leaving Pangkalan Bun for Surabaya: eight were flown in on Saturday, four on Friday. Nine of the bodies are male, three female.

A total of 60 vessels and 20 aircraft are taking part in the operation, with the search currently narrowed down to 1,575 square nautical miles, AFP reported.

Sementara itu, jet yang hilang mungkin tidak mempunyai kebenaran untuk terbang dari Surabaya ke Singapura pada pagi Ahad, dan penerbangannya pada laluan ini telah secara rasmi digantung untuk hari itu dalam seminggu sejak Oktober.

"Kami juga akan menyiasat pihak yang memberi izin kepada AirAsia untuk terbang pada hari itu," Djoko Muratmodjo, yang bertindak Ketua Pengarah untuk penerban-gan udara Indonesia di Kementerian Pengangkutan berkata pada hari Sabtu.

Pegawai-pegawai akan menyiasat semua jadual penerbangan AirAsia.

"Kita tidak akan memberi tumpuan kepada lesen, hanya jadual," Muratmodjo sambil menambah ia adalah mungkin lesen syarikat itu di Indonesia mungkin dibatalkan.

Sebelum Oktober, syarikat penerbangan itu dibenarkan beroperasi di sepanjang laluan yang setiap hari, tetapi pada bulan Oktober, kementerian mengeluarkan permit bagi AirAsia untuk terbang laluan hanya pada hari Isnin, Selasa, Khamis & Sabtu, untuk musim sejuk tahun 2014-an hingga awal 2015, pengangkutan kementerian jurucakap JA Barata berkata.

Meanwhile, the missing jet might have had no permission to fly from Surabaya to Singapore on Sunday morning, and its flights on this route had been officially suspended for that day of the week since October.

"We will also investigate the party that gave permission to AirAsia to fly on that day," Djoko Muratmodjo, acting general director for Indonesia’s air navigation in the transport ministry said on Saturday.

Officials are going to investigate all AirAsia flight schedules.

“We won't focus on licenses, just schedules,” Muratmodjo said adding it was possible the company’s license in Indonesia might be revoked.

Before October, the airline was allowed to operate along that route daily, but in October, the ministry issued a permit for AirAsia to fly the route only on Mondays, Tuesdays, Thursdays and Saturdays, for the winter of late 2014 to early 2015, transportation ministry spokesman J.A. Barata said.

AirAsia flight search: 30 victims’ bodies recovered, 

some of them belted into seats

The bodies of 30 victims of the AirAsia Flight QZ8501 plane crash have been recovered as internationally-backed search operations attempt to locate the remainder of the wreckage amid rough weather conditions.

Five of the victims’ bodies which were recovered were still belted into their seats when they were found, Indonesian Navy official Col. Yayan Sofiyan told local channel Metro TV. Twenty-one bodies were found Friday, the majority by a US naval vessel.

Four bodies have been identified so far. Hayati Lutfiah Hamid was identified Sunday by her fingerprints, and three more bodies were found to be those of passengers Kevin Alexander Soetjipto and Grayson Herbert Linaksita, and crewmember Khairunnisa Haidar Fauzi.

Rear Marshal Henry Bambang Soelistyo, head of Indonesia's National Search and Rescue Agency, has said that bad weather is a concern as his staff attempt to safely conduct the search.

The search is also complicated by the fact that in 1942 one of the largest naval battles of World War II, the Battle of the Java Sea, took place in the area.

Pasukan carian kini menggunakan peralatan sonar dan logam pengesan canggih, AP melaporkan.

Krew berharap apabila fiuslaj terletak ia akan bersama-sama dengan kira-kira 150 penumpang dan kakitangan kabin masih hilang, membawa beberapa bentuk penutupan kepada saudara-mara.

"Kami akan memberi tumpuan kepada pengesanan dalam air," kata Soelistyo dan berikrar untuk mendapatkan semula mayat "saudara-saudara kami . . . apa-apa keadaan yang kita hadapi." Beliau menganggarkan fiuslaj kini pada kedalaman antara 80 dan 100 kaki.

The search team is currently using sophisticated sonar equipment and metal detectors, AP reported.

The crews hope that when the fuselage is located it will have along with it some 150 passengers and cabin staff still missing, bringing some form of closure to relatives.

“We will focus on underwater detection,” Soelistyo said and vowed to recover the bodies of "our brothers and sisters ... whatever the conditions we face." He estimated that the fuselage is currently at a depth of between 80 and 100 feet.

Penyelamat berharap fiuslaj akan mengandungi tinggalan majoriti penumpang dan anak kapal masih hilang dan ia akan memberikan jawapan kepada apa yang boleh menyebabkan Penerbangan 8501 turun ke bawah.

Penyiasat "sedang melihat setiap aspek" ketika mereka cuba untuk menentukan mengapa pesawat itu terhempas, berkata Toos Saniotoso, seorang warga Indonesia penyiasat keselamatan udara.

"Dari segi operasi, faktor manusia, bahagian teknikal, [kawalan trafik udara] yang - semuanya berharga kepada kami," katanya.

The wreckage of the Airbus 320-200 has been dispersed over an area spanning approximately 5 square kilometers. An oil slick has been sighted in a priority search area, according to the search and rescue chief.

Rescuers hope the fuselage will contain the remains of the majority of passengers and crew still missing as well as it would give answers to what could have caused Flight 8501 to go down.

Investigators "are looking at every aspect" as they try to determine why the plane crashed, said Toos Saniotoso, an Indonesian air safety investigator.

"From the operational side, the human factor, the technical side, the [air-traffic control] — everything is valuable to us," he said.

Because of the World War II battle, the Java Sea is the site of several naval wrecks. Indonesian search and rescue agency official S.B. Supriyadi told AFP on Friday that during the hunt for the AirAsia plane, they had located a metal structure but it was found to be an unrelated piece of debris - “possibly a ship which sank.”

INSTRUMEN Beku, KEMALANGAN Sengaja? AirAsia VERSI Nahas kapal terbang MEMBIAK . . .

Reuters/Enny Nuraheni

iLMu2lautan - Penemuan fiuslaj pesawat AirAsia di Laut Jawa yg menimbulkan persoalan baru tentang apa yang menyebabkan kemalangan itu. Versi mungkin terdiri daripada instrumen salah membaca yang membawa kepada sebuah gerai untuk pembunuhan-bunuh diri.

Penerbangan QZ8501 AirAsia tiba-tiba pergi radar pada hari Ahad di Laut Jawa lama selepas perintis yang diminta kawalan udara di Jakarta bagi kebenaran untuk naik lebih tinggi utk mengelakkan ribut. 

Kebenaran itu diberikan 2 minit kemudian, tetapi tiada jawapan dari anak-anak kapal yang diikuti.

Pesawat itu hilang dari skrin radar 3 minit kemudian. Tiada panggilan kecemasan dihantar oleh pesawat. Kedua-dua fakta menunjukkan bahawa ia jatuh dengan cepat, dengan spekulasi awal mengatakan bahawa ia boleh telah mengalami kemusnahan yang teruk dalam masa pertengahan udara. 

Tetapi penemuan badan pesawat berbaring di dalam satu bahagian di dasar laut itu membuktikan sebaliknya.

Memulihkan data dari penerbangan dan perakam kokpit akan menjadi penting untuk mewujudkan kebenaran tentang nasib QZ8501, tetapi beberapa pakar penerbangan menunjukkan bahawa kemalangan AirAsia Airbus A320 mempunyai persamaan dengan satu lagi kejadian penerbangan, iaitu penerbangan AF447 Air France pada tahun 2009.

Pesawat itu telah secara rasmi dikelaskan sebagai hilang selama 2 tahun dan telah ditemui hanya pada tahun 2011. Siasatan menunjukkan instrumen yang dipanggil tiub pitot beku dan memberikan bacaan laju udara palsu kepada anak-anak kapal. Mereka gagal untuk bertindak balas kepada masalah itu dengan sewajarnya dan tidak melihat bahawa kapal terbang adalah kira-kira untuk gerai atau cuba untuk mendapatkannya kembali.

Frozen instruments, deliberate crash? AirAsia plane crash versions multiply . . .

The discovery of the AirAsia airliner’s fuselage in the Java Sea raises new questions about what caused the crash. Possible versions range from misread instruments leading to a stall to a murder-suicide.

AirAsia flight QZ8501 abruptly went off radar on Sunday over the Java Sea shortly after the pilot requested air control in Jakarta for permission to climb higher to avoid a storm. The permission was granted two minutes later, but no response from the crew followed.

The plane disappeared from radar screens three minutes later. No distress call was sent by the plane. Both facts indicated that it fell very quickly, with initial speculation saying that it could have suffered catastrophic destruction in mid-air. But the discovery of the plane’s body lying in one piece on the seabed proved otherwise.

Recovering data from flight and cockpit recorders would be crucial for establishing the truth about the fate of QZ8501, but some flight experts point out that the AirAsia Airbus A320 crash has similarities with another flight incident, that of Air France flight AF447 in 2009.

The plane was officially classed as missing for two years and was found only in 2011. The investigation showed instruments called pitot tubes froze and gave false airspeed readings to the crew. They failed to respond to the problem accordingly and didn’t notice that the plane was about to stall or to try to recover it.

"Tidak ada 2 kemalangan yang sama. Tetapi terdapat syarat-syarat yang sama seperti cuaca, dan kita harus melihat ke dalam dengan teliti," bekas penyiasat nahas udara di Indonesia kepada Reuters.

Tidak seperti kemalangan penerbangan AirAsia, Air France pesawat terhenti pada waktu malam apabila anak-anak kapal tidak dapat melihat garis ufuk dan melihat bahawa pesawat telah kehilangan ketinggian.

QZ8501 telah dipandu oleh yang berpengalaman berusia 53 tahun bekas Tentera Udara Indonesia perintis dikenal dengan nama tunggal Iriyanto, yang mempunyai 20,000 jam penerbangan di bawah tali pinggang beliau, termasuk 6,100 jam di Airbuses. Pembantu juruterbang adalah Perancis Remi Plesel dengan 2,275 jam penerbangan.

Ketua Pegawai Eksekutif AirAsia Tony Fernandes melahirkan keyakinan dalam perintis, mengatakan dia adalah salah seorang graduan yang terbaik di sekolah penerbangan tentera. 

Airbus A320 adalah pesawat yang boleh dipercayai dengan hanya 0.14 kemalangan maut setiap juta berlepas, menurut satu kajian kesela-matan diterbitkan oleh Boeing pada bulan Ogos. 

Dengan tidak kesilapan manusia atau kegagalan teknikal serta-merta dihempap sebagai sebab yang mungkin, teori lebih jahat tentang kemalangan yang telah timbul.

Pesawat itu boleh rosak oleh bom kecil meletup di atas kapal, John Nance, bekas juruterbang Tentera Udara Amerika Syarikat, kepada ABC News.

"Mungkin salah satu yang tidak cukup kuat untuk meniup kapal terbang ke dalam keping pada ketinggian, tetapi mungkin salah satu yang meniup kabel kawalan daripada hidraulik," katanya.

Satu versi yang lebih eksotik akan menjadi kemalangan sengaja oleh juruterbang dalam pembunuhan-bunuh diri, ditambah Nance. Sekurang-kurangnya 3 kemalangan dalam 20 tahun yang lalu adalah disebabkan oleh ini.

Satu contoh ialah Penerbangan 185 SilkAir, juga dari Indonesia, yang terhempas ke dalam sungai di selatan Sumatera pada tahun 1997. 

Penyiasat Indonesia melaporkan bahawa mereka tidak dapat mengumpul bukti kukuh untuk membuat keputusan mengenai punca kejadian itu.

Tetapi Lembaga Keselamatan Pengangkutan Kebangsaan Amerika Syarikat, yang telah mengambil bahagian dalam penyiasatan kerana pesawat berkenaan ialah Boeing 737, berkata pesawat itu terhempas kerana input sengaja dari kokpit, kemungkinan besar oleh kapten.

"No two accidents are the same. But there are similar conditions like the weather, and we must look into it very closely," a former air crash investigator in Indonesia told Reuters.

Unlike the AirAsia flight crash, Air France airliner stalled at nighttime when the crew couldn’t see the horizon line and see that the aircraft was losing altitude.

QZ8501 was piloted by an experienced 53-year-old ex-Indonesian Air Force pilot known by the single name Iriyanto, who had 20,000 flying hours under his belt, including 6,100 hours in Airbuses. The co-pilot was Frenchman Remi Plesel with 2,275 flying hours.

AirAsia CEO Tony Fernandes expressed confidence in his pilot, saying he was one of the best graduates at his military flight school. The Airbus A320 is a reliable aircraft with just 0.14 fatal accidents per million takeoffs, according to a safety study published by Boeing in August. With neither human error nor technical failure immediately pinned down as a likely cause, more sinister theories about the crash have arisen.

The plane could have been damaged by a small bomb exploding onboard, John Nance, a former US Air Force pilot, told ABC News.

"Maybe one that wasn't strong enough to blow the airplane into pieces at altitude, but maybe one that blew the control cables from the hydraulics," he said.

An even more exotic version would be a deliberate crash by the pilot in a murder-suicide, Nance added. At least three crashes in the past 20 years were caused by this.

One example is SilkAir Flight 185, also from Indonesia, which crashed into a river in southern Sumatra in 1997. Indonesian investigators reported that they couldn’t collect conclusive evidence to rule on the cause of the incident.

But the US National Transportation Safety Board, which participated in the investigation because the aircraft in question was a Boeing 737, said the plane crashed due to deliberate input from the cockpit, most likely by the captain.
