National Transportation Safety Board investigators were in North Collins Monday as they continued their investigation into the weekend's fatal plane crash.
Three people died when the two small planes collided mid-air. The Erie County Sheriff's Office says 60-year-old Paul Rosiek of Hamburg was killed, along with Eden residents Richard and Kathleen Walker, who were both 69-years-old.
A representative from the NTSB tells 7 Eyewitness News the planes will be preserved and moved from their location so the investigation can continue. A preliminary report is expected to be completed within the next 10 days, but it will take between six months and a year for the full report to be released.
These small planes don't have black boxes, so investigators with the NTSB will be looking at the pilots' experience, as well as the planes themselves and weather conditions the day of the crash.
Witness statements and radar data will also be used to determine what happened.
