The pilot of a small airplane that crashed in Leslie County April 27 told air-traffic controllers he was "dropping like a rock" just before the crash, according to the National Transportation Safety Board.
The crash killed Stephen J. Reardon, 68, and his wife Beverly Reardon, 59, of Woodbine, Md.
Instrument-flight conditions were in place at the time. The NTSB said Reardon had reported problems with his airspeed indicator.
There were notices for icing and turbulance along the plane's flight path and elevation, the NTSB said in a preliminary investigation report on its Web site.
The plane, a Hawker Beechcraft 58, came almost straight down in a remote, heavily wooded section of the Daniel Boone National Forest.
