Prachuap Khiri Khan: The National Police Inspector General has released the findings of the investigation into the Bell 212 helicopter crash that occurred in Prachuap Khiri Khan. Initial results indicate that two bolts securing the tail rotor had come loose, leading to the helicopter losing stability and severing the tail. The report is set to be submitted to the National Police Chief, confirming that there was no falsification to mislead the public.
According to Thai News Agency, Pol. Gen. Thatchai Pitaneelabut, Inspector-General of the Royal Thai Police, convened a meeting to assess the progress of the investigation into the tragic helicopter crash, which claimed the lives of three pilots and a mechanic. The meeting, attended by Pol. Lt. Gen. Itthiphol Atchariyapradit, Deputy Inspector-General, Pol. Maj. Gen. Amnat Detbunlueang, Commander of the Police Aviation Division, pilots, and related agencies, was aimed at identifying the cause of the accident. Following the meeting, the Inspector-General and participants examined the wreckage of the helicopter, which was then transported to the police station for evidence collection.
Pol. Gen. Thatchai reported that he was tasked by the National Police Commissioner to investigate the incident thoroughly by collaborating with the air force commander, pilots, and mechanics. The investigation explores various factors, including the helicopter manufacturer's involvement and budget allocations for maintenance, to determine the accident's precise cause. The Police Investigation Bureau has been invited to assist in uncovering the truth.
The preliminary findings suggest that the large tail rotor failed due to loose bolts, resulting in the rotor's imbalance and severing of the helicopter's tail rotor, crucial for directional control. The investigation is ongoing to determine whether the bolts loosened from use or maintenance, despite having over 600 hours of service life remaining. Thai Airways, a contracted partner for maintenance, and the Royal Thai Police are both involved in maintenance processes, with minor repairs conducted by the police themselves.
The Inspector-General emphasized the importance of identifying whether the fault lies in manufacturing or maintenance, assuring accountability for the incident both criminally and civilly. The investigation seeks to confirm whether maintenance was ever outsourced to the Air Force, as such documentation can be scientifically and clearly verified.
Pol. Maj. Gen. Amnat Detbunlueang reiterated the importance of pilot and aircraft safety, highlighting that the crash is a significant concern due to two incidents occurring within 30 days. The division is actively gathering evidence to ascertain the true cause of the crash, whether it be material failure or maintenance issues.
In light of the crash, the police aviation division will opt for Euro aircraft for upcoming missions, while emphasizing thorough inspections to prevent future mishaps. When questioned about the choice of aircraft, a stuttering response indicated the ongoing caution and safety prioritization in aircraft selection.
