ELBA, N.Y. (WIVB) — The National Transportation Safety Board has released more information regarding the April 26 Mercy Flight crash, which killed Mercy Flight pilot James Sauer and Bell pilot Stewart Dietrick.
The report said the instructional flight was a “flight review,” with multiple reviews scheduled throughout the day. Sauer’s flight review was the second flight of the day. The helicopter was reportedly in the air from 11:10 a.m., until its crash around 1 p.m., performing multiple maneuvers in that time.
The helicopter reached as high as 2,600 feet mean sea level (msl), ascending and descending, while completing maneuvers. Prior to the crash, the helicopter was last reported at 1,975 feet msl; it is said to have hit the earth at 1,220 feet msl.
The report also detailed eyewitness accounts:
Several eyewitnesses observed and heard the helicopter flying overhead before to the accident. One stated that he observed the helicopter “almost stationary” after it flew over, and then as it started to fly away, he heard a loud “bang”, and the helicopter began to descend out of control. An additional witness stated that the helicopter was hovering before it “fell apart” with the fuselage falling separately and another witness stated she did not see the helicopter but heard what sounded like an engine making a “whooshing” sound, then “three loud and rapid cracks” in succession. She further stated that she heard the helicopter impact the ground and heard the rotor blades striking the ground rapidly.NTSB Accident Report
