Federal Aviation Administration Monthly Accident & Incident Data for the Month of March 2015


Preliminary Injuries: 1 Fatal


On March 6, 2015, at 2310 central standard time, an Airbus Helicopters


(Eurocopter) EC-


130-B4, N356AM, operated by an EMS provider, struck the edge of a hospital building and impacted its parking lot during a visual approach to the St Louis University Hospital elevated


rooftop helipad


(MO55), St Louis, Missouri. During the approach, the helicopter experienced a loss of directional control and entered an uncontrolled descent. The helicopter was destroyed by impact forces and a post-crash


fi re. The commercial pilot, who was the sole occupant, sustained fatal injuries. The helicopter was operated under Title 14 CFR Part 91 as an air medical positioning fl ight that was operating on a company fl ight plan. Night visual meteorological conditions prevailed at the time of the accident. The fl ight was returning to MO55 after it had been refueled at the operator’s base in St. Louis, Missouri.


The fl ight’s fi rst approach and landing at MO55 was to drop off a medic, nurse, and a patient. During the approach, the pilot reported to the fl ight


nurse and medic that winds were gusting to 25 knots. The fl ight nurse stated that the helicopter was yawing quite a bit and there was a noticeable roll side to side during landing. The helicopter landed without incident during the fi rst approach and landing. The fl ight then departed to obtain fuel at the operator’s base, and then departed to return to MO55 to pick up the medic and fl ight nurse.


The accident occurred during the return’s approach for landing at MO55.


Examination of the wreckage confi rmed fl ight control continuity


of the tail consistent
