What happened
During an early morning charter flight, a helicopter crashed while traveling from Ballynahinch Castle toward Shannon Airport. The aircraft struck the ground at a location situated north of its intended direct overland flight path. The impact, which occurred while the aircraft was being operated at a low altitude, resulted in five fatalities, including the pilot and all four passengers.
At the time of the accident, the area was experiencing widespread radiation fog, which led to fluctuating and highly restricted visibility levels during the flight.
The investigation
Investigators examined the aircraft and found no evidence of mechanical defects or pre-existing technical issues prior to the crash. The inquiry focused on the flight conditions and the pilot's navigation during the period of deteriorating visibility. The investigation established that the aircraft was maneuvering at low altitude under challenging atmospheric conditions.
Findings
- The accident was likely triggered by the pilot's loss of adequate visual references.
- The pilot may have experienced spatial disorientation due to induced false sensations caused by the changing environmental conditions.
- The pilot attempted to maintain the flight despite the worsening visibility.
- Factors such as the rapidly changing visual environment and potential pressure to complete the mission may have contributed to the outcome.
