Incident Overview
While conducting a chemical application flight over a field, the pilot inadvertently allowed the aircraft's right main landing gear to contact a 20-foot-high post. Following the impact, the pilot continued the application, dispersing the remainder of the chemical load before returning to the airstrip being used as a base of operations.
Landing and Collapse
Aware that the right main landing gear had been damaged, the pilot intentionally held the right wing higher than the left for as long as possible during the landing roll. However, when the right main gear eventually made contact with the landing surface, it collapsed. The collapse caused the right wing to strike the ground, resulting in substantial damage to the right wing's main spar.
Damage Assessment
The aircraft sustained substantial damage to the right wing main spar. No other damage or injuries were reported in the source material. The pilot's actions to mitigate the situation were limited to holding the right wing up during landing, but the gear failure was unavoidable given the prior damage.
