The pilot was not sure that the engine would continue to run if he diverted to the nearest grass strip, so he executed a precautionary landing to a field, which substantially damaged right wing ribs and spar. Postaccident examination of the airplane revealed that the oil cap was missing; it was later located at the last departure airport. The pilot stated that he was in a hurry to depart and did not properly reinstall or secure the oil cap. The did not reveal other mechanical anomalies that would have precluded normal operations.
