What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) A/c struck static wire of high voltage transmission lines during aerial application operations. Pilot was conducting pullup manuever after swath run when line was encountered. Pilot indicated that he did overfly and review the area prior to application operations for this field but did not see this wire. Wire strick damage was primarily to the propellor, which immediately affected the pitch change mechanism for at least one blade. This resulted in a severe vibration aand loss of oil through the propellor hub. As pilot was no longer able to generate safe thrust through the propellor an emergency landing was affected, resulting in the eventual encounter with mature orchard trees, resulting in substantial damage to a/c
