The accident happened at around 4PM. The crash site was reportedly one mile northeast of the Whiskey Creek Airport.

The weather sequence, recorded eight miles to the south at the regional airport, strongly suggests weather as a causal factor.

20140523.. [94E] satellite view of airportClouds and visibility were not an issue, but winds were strong, gusting, and shifting. The automated weather observations were being recorded at twenty-minute intervals, perhaps due to the rapidly changing winds. A half hour before the accident, a single observation offered nearly calm winds of just four knots, straight from the south (thus aligned with the runway). But, the calm was short-lived; the next observation marks the start of a substantial windshift, with strong and gusting crosswinds from the west. Some pilots would refer to this one anomalous weather report as a ‘sucker hole’. There is no report yet as to when the aircraft took off, or how long the flight had been in the air when it came back to land.

The privately owned airport is located 4 miles east of Silver City. The VFR sectional shows Black Peak is nine-miles to the north , looming nearly 3,000 feet above the 5,400 foot long runway surface. This geographic proximity typically increases the likelihood of intense windshifts.

This time of year is known for rapidly shifting weather. However, this accident may be an indicator of a slowly emerging trend that threatens General Aviation. The increased energy in our atmosphere may be causing more intense and more frequent shifts. Because of their low weight and low altitudes of operation, small aircraft may prove to be particularly vulnerable to intensified flight hazards related to climate change.20140523..
