What happened
The pilot was cleared for the ILS Runway 27 approach. During the final approach, the airplane encountered light to occasional moderate turbulence, necessitating a 30-40 degree drift correction to stay on course. At approximately 2 miles from the runway, the tower controller reported winds of 300 degrees at 18 knots.
As the aircraft descended to between 100 and 50 feet above the ground, the pilot noted that the crosswind subsided dramatically, allowing for runway alignment without further wind correction. The landing proceeded normally until the airplane was 3-5 feet above the runway surface, at which point the pilot experienced significant and abrupt buffeting.
The aircraft then weather-vaned to the right and rolled to the left, causing it to drift left of the centerline. Despite corrective actions taken by the pilot, the airplane touched down nose wheel first, bounced back into the air, and subsequently touched down nose wheel first a second time. This sequence resulted in the nose gear collapse and caused the propellers to contact the runway.
