The NTSB's narrative final · quoted from the NTSB record

The pilot reported that while in cruise flight, he noticed that his heavy keychain was pulling the key out of the ignition switch. He reached down to push the key back in, but inadvertently moved the key to the off position due to the thick glove on his hand, which resulted in a loss of engine power. When he attempted to reinsert the key and restart the engine, the key broke inside the ignition switch. He was unable to use the broken key to restart the engine. During the forced landing, the airplane sustained substantial damage to the right wing. The pilot reported that there were no other mechanical malfunctions or failures with the airplane that would have precluded normal operation.
