Panicky pilots caused Adam Air tragedy

AN Indonesian jetliner smashed into the ocean, obliterating all trace of its 102 occupants, after its pilots accidentally disengaged the autopilot while they were trying to reset a failed navigational system, an inquiry has found.

The Adam Air Boeing 737 was en route from Surabaya, East Java, to Manado, North Sulawesi, when it foundered on New Year’s Day last year.

The investigation details the terrifying final moments as the two inexperienced and poorly trained pilots veered off course in stormy weather, tried to reset their malfunctioning instruments using a guide book that had been downloaded from an unauthorised website and then failed to right the craft as it banked and dived almost 25,000 feet in just over a minute.

The findings probably come too late to affect the company: Adam Air was grounded last week on safety concerns, days after announcing it was insolvent and needed tens of billions of rupiah to continue operating.

The operator, founded by parliamentary speaker Agung Laksono and businesswoman Sandra Ang – and named for her chief executive son Adam, 27, – has a history of going off course at the strategic and operational level.

The pilots of the doomed flight DHI 574 can be heard on the cockpit voice recorder expressing panic that they were heading in the wrong direction and into a violent storm.

The two became so fixated on rectifying the problem that they ignored automated cockpit warnings to take control of the plane as it banked 100 degrees to the right and then pitched 60 degrees forward.

One year previously, an Adam Air flight had veered hundreds of kilometres from its intended route and landed on a little-used airstrip in Sumbawa, eastern Indonesia. Investigations into the instrument failure that caused that incident were criticised as cursory and part of a political cover-up.

A National Transportation Safety Committee senior director Mardjono Siswosuwarno admitted yesterday it was possible the same equipment failure that caused the 2006 incident was behind last year’s disaster.

The crashed aircraft’s Inertial Reference System, which helps the autopilot system maintain its bearing, had failed multiple times in the months before the disaster, according to Adam Air maintenance records.

However, investigators found senior pilots at the airline were unable to explain how the IRS system worked. Nor did the airline provide training in IRS system failure or in how to right an upset aircraft.

The report notes a range of failings in individual pilot abilities and the airline’s training and maintenance regimes.

It suggests the entire industry has a long way to go before an estimated 34 million passengers per annum can fly with any expectation of safety.

Indonesia recently signed a $22 million transport safety assistance package with Australia, and trains with the International Aviation Safety Commission. Last month, it received a surprise award for its air traffic control systems from the prestigious Jane’s Airport Review, although a European Union ban remains on Indonesian aircraft flying in its airspace.

Herman Mulyadi, an air force colonel and medical doctor who is also a member of the National Transportation Safety Committee, said yesterday the Adam Air crash should not be regarded as the result of “human error” but rather of “human failing … because this is one of the risks of flying”.

“There was a failure in human performance and to err is human,” he said. [Stephen Fitzpatrick]

  1. “Aku tahu, bahwa Engkau sanggup melakukan segala sesuatu, dan tidak ada rencana-Mu yang gagal.
    Firman-Mu: Siapakah dia yang menyelubungi keputusan tanpa pengetahuan? Itulah sebabnya, tanpa pengertian aku telah bercerita tentang hal-hal yang sangat ajaib bagiku dan yang tidak kuketahui.
    Firman-Mu: Dengarlah, maka Akulah yang akan berfirman; Aku akan menanyai engkau, supaya engkau memberitahu Aku.
    Hanya dari kata orang saja aku mendengar tentang Engkau, tetapi sekarang mataku sendiri memandang Engkau.
    Oleh sebab itu aku mencabut perkataanku dan dengan menyesal aku duduk dalam debu dan abu.”

    Setelah TUHAN mengucapkan firman itu kepada Ayub, maka firman TUHAN kepada Elifas, orang Teman: “Murka-Ku menyala terhadap engkau dan terhadap kedua sahabatmu, karena kamu tidak berkata benar tentang Aku seperti hamba-Ku Ayub.
    Oleh sebab itu, ambillah tujuh ekor lembu jantan dan tujuh ekor domba jantan dan pergilah kepada hamba-Ku Ayub, lalu persembahkanlah semuanya itu sebagai korban bakaran untuk dirimu, dan baiklah hamba-Ku Ayub meminta doa untuk kamu, karena hanya permintaannyalah yang akan Kuterima, supaya Aku tidak melakukan aniaya terhadap kamu, sebab kamu tidak berkata benar tentang Aku seperti hamba-Ku Ayub.”
    Maka pergilah Elifas, orang Teman, Bildad, orang Suah, dan Zofar, orang Naama, lalu mereka melakukan seperti apa yang difirmankan TUHAN kepada mereka. Dan TUHAN menerima permintaan Ayub.

    Lalu TUHAN memulihkan keadaan Ayub, setelah ia meminta doa untuk sahabat-sahabatnya, dan TUHAN memberikan kepada Ayub dua kali lipat dari segala kepunyaannya dahulu.
    Kemudian datanglah kepadanya semua saudaranya laki-laki dan perempuan dan semua kenalannya yang lama, dan makan bersama-sama dengan dia di rumahnya. Mereka menyatakan turut berdukacita dan menghibur dia oleh karena segala malapetaka yang telah ditimpakan TUHAN kepadanya, dan mereka masing-masing memberi dia uang satu kesita dan sebuah cincin emas.
    TUHAN memberkati Ayub dalam hidupnya yang selanjutnya lebih dari pada dalam hidupnya yang dahulu; ia mendapat empat belas ribu ekor kambing domba, dan enam ribu unta, seribu pasang lembu, dan seribu ekor keledai betina.
    Ia juga mendapat tujuh orang anak laki-laki dan tiga orang anak perempuan;
    dan anak perempuan yang pertama diberinya nama Yemima, yang kedua Kezia dan yang ketiga Kerenhapukh.
    Di seluruh negeri tidak terdapat perempuan yang secantik anak-anak Ayub, dan mereka diberi ayahnya milik pusaka di tengah-tengah saudara-saudaranya laki-laki.
    Sesudah itu Ayub masih hidup seratus empat puluh tahun lamanya; ia melihat anak-anaknya dan cucu-cucunya sampai keturunan yang keempat.
    Maka matilah Ayub, tua dan lanjut umur.
