Emergency landing goes badly

Aircraft: Glasair III. Injuries: None. Location: Darby, Mont. Aircraft damage: Substantial.

What reportedly happened: According to the pilot, approximately two hours into a VFR cross-country flight, he noted indications of excessive cylinder head and exhaust gas temperatures.

He attempted to correct the issue by enrichening the mixture, which resulted in a higher fuel burn than he had planned, so he diverted to a closer airport.

While en route to his amended destination, he encountered instrument meteorological conditions. A subsequent buildup of ice resulted in a loss of 100 knots of airspeed as the airplane entered a controlled descent.

The pilot executed a 180° turn and broke out of the clouds over a valley. During the next 50 minutes, he made several attempts to exit the valley, however, mountain peak obscuration and a thunderstorm prevented him doing so.

With the airplane very close to fuel exhaustion, he elected to land on a two-lane highway. During the landing roll the airplane went off the side of the road, into a tree and came to rest in a concrete drainage culvert.

Probable cause: The pilot’s loss of directional control during an emergency landing on a paved highway.
