JAKARTA The NBO-105 helicopter belonging to the National Police with registration number P-1103 crashed in the waters of East Belitung, Bangka Belitung Islands on November 27, 2022. The National Police, to date, are still searching for victims and collecting the remaining fragments of helicopters.
Aircraft accidents are usually caused by three factors: humans, machines, and the media. Human factors, according to the Co-Founder Institute for Security and Strategic Studies (ISESS) Khairul Fahmi, include his ability, knowledge, experience, and readiness to fly.
The engine factor includes the feasibility of the aircraft including all its components. Meanwhile, media factors concern natural conditions related to weather.
However, in this case, the National Police Chief General Listyo Sigit Prabowo has confirmed that the Polairud helicopter type NBO-105 is in an airworthy condition. Thus, the main cause is not because of the engine or human error, but because of weather factors.
The weather problem is very important for flights. The weather is not always predictable. Especially, if the distance is long, for example. When you are about to travel, it is declared clear, but in the middle of the trip suddenly the conditions change, the storm arrives, while the position of the helicopter does not allow landing. This could happen," Khairul told VOI, Wednesday (30/11).
It could also be due to a combination of weather and humans, human error worsens the condition. When facing bad weather, the pilot must respond quickly and appropriately. If the decision taken is wrong, the result is very fatal, "continued Khairul.
Winds, air pressure, clouds, rain, and fog certainly greatly affect the flight situation and its movement sometimes changes rapidly. That's why, there needs to be further investigations to be sure.
"The accident, whatever the cause, needs to be an investigation. What is no less important, evaluation," said Khairul.
Evaluation must be carried out thoroughly. Starting from considerations in policies that involve the governance of defense equipment, such as use, maintenance, to human resource competencies.
I believe that regarding the maintenance, everything has a standard procedure. But still, it must be ensured again, whether it has really been ordered in the sense that nothing has been reduced or neglected. This must be evaluated in order to become a lesson and minimize the potential emergence of similar incidents," Khairul explained.
Likewise, HR competence. Pilots are also required to update their skills in dealing with flight conditions in various types of extreme weather scenarios. With the increase in pilot experience, it will help the pilot make the right decisions when needed.
The P-1103 and P-1113 take off helicopters from Palangkaraya, Central Kalimantan at around 08.15 WIB and arrived at Pangkalan Bun at around 11.00 WIB. Two helicopters then continued their journey to Tanjung Pandan, Belitung underwent assistance duties.
Then, said Karo Penmas Polri Brigadier General Ahmad Ramadhan, the weather worsened in the middle of the trip. P-1113 decided to go up to an altitude of 5,000 feet. Meanwhile, the P-1103 pilot failed to raise his altitude and continued to descend to an altitude of 3,500 feet.
After successfully avoiding bad weather, the pilot captain of the P-1113 helicopter communicated to the pilot P1103 via the radio frequency of the helicopter, but there was no answer.
The P-1113 helicopter landed at Tanjung Pandan Airport at 14.24 WIB. Meanwhile, P-1103 containing 4 people was declared missing on November 27 afternoon," said Brigadier General Ahmad Ramadhan.
The bodies of the three helicopter crews, Bripda Khoirul Anam, First Brigadier M Lasminto, and Aipda Joko M have been found. Police are still trying to find another helicopter crew, AKP Arif Saleh.
"Of course, for soldiers who die at their place of duty it is an honor. Therefore, of course, we pray for the deceased to be accepted in the best place by His side," said General Listyo Sigit, Wednesday (30/11).
