Narrative:
The pilot had flown the aerial application flight for 12 minutes when he began to 'get oil on [the] windshield, and [began] losing oil pressure'. A precautionary landing ensued. During the landing roll, the right wing struck a tree. The airplane spun around and slid aideways, collapsing the left landing gear. The left wing was also 'wrinkled.' The pilot said he found the oil dipstick had not been secured.

Probable Cause: The pilot's inadequate preflight inspection of the airplane. Factors were the unsecured oil dipstick, the loss of engine oil pressure necessitating a precautionary landing on unsuitable terrain, and the collision with the tree.
