- [Maneuvering-low-alt flying: Low altitude operation/event](https://openairdocs.org/ntsb-events/220) (defining event); cases with it: [Air Tractor AT-602, 15 cases](https://openairdocs.org/ntsb-events/220/sequence.md?model=0390309), [All aircraft, 780 cases](https://openairdocs.org/ntsb-events/220/sequence.md)

## Analysis

The pilot reported that while maneuvering the airplane to set a starting line for aerial application to a field, the airplane’s right main landing gear struck a power line pole. The pilot immediately returned to the airport. Upon landing, the left main landing gear collapsed. The airplane sustained substantial damage to the fuselage and right wing. The pilot did not report any preaccident failures or malfunctions with the airplane that would have precluded normal operations.
