BANDAR SERI BEGAWAN
A BOARD of inquiry has found that"human error" was to blame for the fatal crash of a Royal Brunei Air Force (RBAirF) helicopter last July, stating that the aircraft was flying at an "unauthorised low level" causing it to collide with two trees in the Belait jungle.
Initial findings released by the Ministry of Defence yesterday also said that the Department of Civil Aviation did not follow procedure when it failed to notify the military that the Bell 212 chopper had not made contact with air traffic control for more than 30 minutes.
The helicopter was carrying 14 military personnel back from jungle training in Mukim Labi when it crashed killing 12 onboard.
There was no evidence of bad weather or technical error, said Commander of the Royal Brunei Navy First Admiral Dato Seri Pahlawan Hj Abd Halim Hj Mohd Hanifah, who headed the military's investigation.
This was confirmed by three independent investigation teams Pratt and Whitney Canada, Bell Textron United States and the United States Army Combat Readiness Center Air Accident Investigation Team who were engaged to assist the inquiry.
Speaking to reporters, Dato Hj Abd Halim said piecing together the closest scenario without the help of a black box which Bell 212 choppers are not equipped with was a difficult task.
According to evidence gathered during the investigation, it is believed the pilot was flying at an "unauthorised low level" with speeds around 60-80 knots near Wasai Wang Tebadak. The aircraft banked at a 45 degree angle in order to follow the path of the river and strayed from its original height due to "g-force" factors. The pilot was unable to raise the aircraft's altitude causing it to collide with two trees.
The Bell 212 is believed to have crashed at 10.15am, more than an hour after it took off at 8.55am. The last radio contact made with air traffic control was at 9.17am.
According to Department of Civil Aviation procedure, each aircraft is required to make the an "Ops Normal Call" every 30 minutes but air traffic control did not inform RBAirF when the Bell 212 had not made contact for more than 30 minutes. Due to this, the "INCEFRA" (uncertainty phase) was not executed nor RBAF distress procedure.
The search and rescue mission only began at 1.53pm, when the aircraft was confirmed missing. Aircraft debris was first found in the area near Wasai Wang Tebadak at 3:55pm.
In the wake of the crash, Dato Hj Abd Halim said safety procedures would need to be "tightened" to prevent similar incidents from recurring.
"The procedures need tightening up, the training, and time maybe. Also we look at this holistically it will be a process that will be painful but there is no other way."
When asked how the accounts of the two survivors, who have been discharged from hospital, factored into the investigation, he said: "We listened to the statements of the survivors but as you all know they are also facing a difficult time to recap what was going on. And all statements must be backed with evidence at the crash site."
A full report complete with recommendations will be submitted to the Commander of the Royal Brunei Armed Forces (RBAF) on September 16.
A briefing for families of the crash victims was also held yesterday at the officers' mess at Bolkiah Garrison.
RBAF Commander Major General Dato Paduka Seri Hj Aminuddin Ihsan Pehin Orang Kaya Saiful Mulok Dato Seri Paduka Hj Abidin said families of the deceased officers would receive their pensions and other benefits.
"We will take care of the welfare of the families... The families of the officers and trained soldiers will be getting their pensions and gratuities and we will hasten the process."
When asked how the families reacted to the inquiry's findings, he said: "I have to say that things are being taken in a good way, in a very calm situation. The families are sad, and that is also what the armed forces are feeling in facing this tragedy. I think that the information is being made transparent to them, which is what we are trying to highlight here."
Dato Hj Abd Halim added: "It is something that is very difficult to swallow... But we have worked very hard to come to the nearest picture (from the evidence) we can collect."

LIPUTAN MEDIA PESAWAT BELL 212 TERHEMPAS DI ULU RAMPAYOH MUKIM LABI PADA 20 JULAI 2012
Assalamu’alaikum Warahmatullahi Wabarakatuh
Bismillahir Rahmanir Rahim
Berikut adalah hasil penemuan Lembaga Penyiasatan:
Pesawat Bell 212 milik Tentera Udara Diraja Brunei bersama 14 orang anggota (3 krew pesawat dan 2 jurulatih, 1 kakitangan dan 8 Pegawai Kadet, Sekolah Pegawai Kadet) telah terhempas berdekatan dengan Wasai Wang Tebadak, Mukim Labi pada hari Jumaat, 20 Julai 2012 ketika membuat penugasan pengangkutan balik anggota yang telah menjalani latihan ketenteraan dari Tapak Pendaratan KB 404 ke Tapak Pendaratan KB 199. Pesawat tersebut dipercayai terhempas kira-kira jam 10.15 pagi.
Pesawat berlepas dari pangkalan TUDB sekitar jam 8.55 pagi dan perhubungan radio terakhir pesawat dengan Brunei Radar ialah pada jam 9.17 pagi. Mengikut prosedur penerbangan Kawalan Lalulintas Udara, Jabatan Penerbangan Awam, setiap pesawat yang beroperasi di ruang udara negara adalah dikehendaki membuat perhubungan ‘ops normal call’ setiap 30 minit. Akan tetapi tidak ada sebarang perhubungan yang dibuat selepas itu dan pihak Kawalan Lalulintas Udara, Jabatan Penerbangan Awam tidak melakukan tindakan ‘INCERFA’ (uncertainty phase) dan memaklumkan kepada pihak ABDB untuk melaksanakan distress procedure. Ini berlarutan sehingga beberapa jam kemudian mengakibatkan tindakan ‘alerting service’ tidak dilaksanakan mengikut prosedur.
Operasi Mencari dan Menyelamat hanya dimulakan sejurus pesawat tersebut disahkan hilang oleh pihak Tentera Udara Diraja Brunei kira-kira jam 1.53 petang. Serpihan pesawat ditemui di kawasan berdekatan Wasai Wang Tebadak kira-kira jam 3.55 petang.
Kementerian Pertahanan dan ABDB telah menubuhkan satu Lembaga Penyiasatan Tertinggi pada 25 Julai 2012. Lembaga ini dipertanggungjawabkan untuk menjalankan penyiasatan ke atas pesawat yang terhempas dan mencari punca serta fakta-fakta yang berhubung kait dengan kemalangan tersebut serta membuat saranan-saranan yang perlu diambil agar kemalangan seumpama ini tidak berulang lagi.
Lembaga Penyiasatan ini juga dibantu oleh beberapa buah organisasi pakar penyiasatan pesawat dari luar negeri iaitu Pratt and Whitney Canada dan Bell Textron United States dan United States Army Combat Readiness Center – Air Accident Investigation Team.
Lembaga Penyiasatan telah mendapati fakta-fakta berikut:
a. Environment. Cuaca semasa kejadian adalah baik dan tidak menjejaskan operasi penerbangan.
b. Material. ‘Airworthiness’ pesawat tersebut adalah di tahap yang sepatutnya. Tiada bukti yang menjurus kepada pesawat menghadapi sebarang masalah teknikal sebelum pesawat terhempas. Perkara ini turut disahkan oleh 3 tim penyiasat luar negara yang berasingan.
Fakta punca kemalangan adalah seperti berikut:
a. Human Factor. Punca utama pesawat tersebut terhempas ialah atas kesilapan manusia (Human Error). Pesawat berkenaan terlibat dalam Controlled Flight into Terrain (CFIT) semasa membuat penerbangan unauthorised low level flying.
b. Procedure. Juruterbang telah melakukan penerbangan yang bertentangan dengan prosedur iaitu unauthorised low level flying.
Lembaga Penyiasatan secara gambaran terdekat mendapati bahawa sebelum kejadian, juruterbang telah melakukan unauthorised low level flying dengan kelajuan sekitar 60-80 knots di kawasan Wasai Wang Tebadak (LP KB 195A) dan seterusnya telah mengerengkan (banking) pesawat dengan anggaran 45 darjah untuk mengikuti laluan sungai. Pesawat telah tersasar dan terturun dari ketinggian asal disebabkan faktor g-force. Pesawat merempuh dahan-dahan kayu pokok pertama dan tidak melalui laluan yang dihasratkan setelah di dalam keadaan straight and level. Pada saat-saat akhir pesawat cuba untuk menaikkan ketinggian tetapi tidak berhasil dan terus merempuh dua pokok besar.
Beberapa saranan tegas telah diajukan dalam laporan awal pertama pada 6 Ogos 2012 dan beberapa tindakan khususnya dalam menguatkan lagi proses dan prosedur serta aspek keselamatan telah diambil. Laporan lengkap akan dihadapkan pada 16 September 2012, termasuk saranan-saranan bagi memastikan kejadian seperti ini tidak akan berulang lagi. Insya’Allah.
