After applying the fourth load, the pilot returned to the airstrip for another load. During the landing the pilot applied both brakes; however, there was no response from the right brake. The pilot reported that he pumped the brake several times, but it still did not function. The pilot then applied full left brake and the airplane spun 180-degrees, collapsing the right main landing gear. The airplane impacted a ditch and electrical pole, before coming to rest. The reason for the loss of brake pressure was not determined. ## Factual narrative The operator was conducting an aerial spraying operation from a private airstrip, and had completed three loads, earlier in the morning. After applying the fourth load, the pilot returned to the airstrip for another load. During the landing the pilot applied both brakes; however, there was no response from the right-side brake. The pilot reported that he pumped the brake several times, but still no response. The pilot then applied full left brake and the airplane spun 180-degrees, collapsing the right (main) landing gear with the propeller striking the ground. The airplane impacted a ditch and electrical pole, before coming to rest. The reason for the loss of brake pressure was not determined ## Aircraft - Registration: [N63E](https://openairdocs.org/aircraft/N63E), registered now, S/N 305B, built 1977 (OpenAirDocs) - Reported make and model: GRUMMAN ACFT ENG COR-SCHWEIZER G-164B - Registry model: [Grumman Acft ENG Cor-Schweizer G-164B](https://openairdocs.org/model/grumman-acft-eng-cor-schweizer-g-164b) (registry code 3952802) (OpenAirDocs) - Registry engine: [Walter M601 series](https://openairdocs.org/engine/walter-m601-series) (registry code 64002, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 305B - Engines: WALTER M601 SER 751 horsepower turbo prop - Damage: Substantial damage - Flight: Aerial application, Part 137 - Operator: Kinder Ag Service - Registered owner: Kingrey William S III - Airworthiness certificate: Special, Restricted (Special) - Departed: Pvt, Basile, LA - Destination: Pvt, Basile, LA - Airport: Pvt, Private ## Flight crew As NTSB recorded them.
