This past week the National Transportation Safety Board (NTSB) published a report about the July 3, 2015 crash of an Airbus AS350B3e conducting Helicopter Air Ambulance (HAA) operations in Colorado. As seen in video at the base helipad, the aircraft yaws left while skids are on the ground and then continues to yaw left as the helicopter becomes airborne and goes out of camera view. The helicopter reappears as it crashes behind the site, and a post-crash fire develops almost instantly. What happened? What actions could the pilot have taken?
During some recent helicopter recurrent training we discussed various accidents and reviewed videos of said accidents. While analyzing accident video is an important method for learning ways to avoid making the same mistakes, something else can be gleaned from this available evidence: everybody is recording video or taking photos of our helicopter flight. We are in the public’s eyes at all times.
It never ceases to amaze me how frequently two aircraft, with so much airspace available, can converge and require a course/altitude adjustment to prevent collision. As pilots we have to maintain vigilance in scanning for traffic. While Traffic Collision Avoidance Systems (TCAS) and verbal traffic alerts from controllers help, they don’t replace the need to visually scan. At uncontrolled/non-towered airports this becomes even more vital as there are no controllers to help you, and inexperienced and/or poorly-trained pilots are drawn to these locations.
Thankfully, the month of December was light in helicopter accidents. The National Transportation Safety Board (NTSB) is still in the process of investigating the accidents listed, so myself nor other readers can really judge the cause of each accident without further information. However, based upon the preliminary information, we can get an idea about what related subjects we should review to help prevent such accidents on our end.
