Details released for pair of Routt County plane crashes

STEAMBOAT SPRINGS — The National Transportation Safety Board has issued its reports on the probable causes of two deadly plane crashes that occurred in Routt County last year. Investigators concluded that a crash at Yampa Valley Regional Airport in Hayden likely was caused by snowy weather, and a pilot killed in a crash north of Milner was flying while impaired by alcohol and marijuana.

The crash at Yampa Valley Regional Airport killed two people and seriously injured four. The crash north of Milner killed the pilot.

According to reports, Peter Landherr was flying alone from Glenwood Springs back home to Minnesota on Aug. 24 to help his ex-wife and children say goodbye to their dying dog, Schuck, when he crashed in a remote area northwest of Milner. The wreckage of the Piper was discovered hours later by sheep herders.

In a report released last month, the NTSB determined Landherr was impaired by alcohol, marijuana and a lack of oxygen from flying above a safe altitude.

The report said an opened six-pack of beer was found in the cockpit within the pilot’s reach.

Investigators said tests showed Landherr likely was consuming the alcohol and smoking within one to two hours of the crash.

In a crash in February last year, Corpus Christi businessman Scott Humpal and his family were on their way to a ski vacation in Steamboat Springs when their private plane crashed short of the runway during a snowstorm.

The accident killed the pilot, Hans Vandervlugt, and Humpal’s wife, Gaby.

In a report released in May, the NTSB determined the probable cause of the crash was “the pilot’s inadvertent stall during a missed approach” that may have been caused by ice on the plane.

The crash seriously injured Scott Humpal and his three children.
