Investigating agency: ASC
Narrative:
The helicopter, engaged in an aerial photography mission, crashed under unknown circumstances. Post-impact fire. All three occupants died in the crash.

Findings Related to Probable Causes
1. The collected evidences show that the captain encountered the following conditions: possible side effect of Chlorpheniramine, one kind of antihistamine, a minimum rest period allowed by regulations before the occurrence, high flight time, long duration of helicopter vibration, low altitude and mountainous area operation, high temperature in cockpit, which possibly caused the captain fatigued, or was in a state of reduced mental or physical performance. However no direct evidence is able to illustrate effects of the above issues that could impair captainís alertness and ability to safely operate the helicopter.
2. Weather information near crash site and flight simulation results both show that wind condition was within the operational limits; however, the actual weather condition cannot be confirmed due to fast-changing weather at the mountainous area, and simulated results were not validated with observed data.
3. Without flight information from flight recorder(s), no wreckage and powerplant examinations due to post-impact fire, flight control system and powerplant conditions cannot be determined.
