The pilot said that during the takeoff roll, the airplane veered to the left, and he applied right rudder to correct the veer, but the airplane subsequently ground looped to the left. The right main landing gear collapsed, and the right wing and right horizontal stabilizer struck the ground. The airplane sustained substantial damage to the right wing, right horizontal stabilizer and fuselage. The pilot said that there were no preaccident mechanical problems with the airplane. ## Factual narrative The pilot was departing from a dry, paved runway in a tailwheel-equipped airplane, which required a correction for a 5 knot, right crosswind. The pilot said that during the takeoff roll the airplane began to veer to the left, and he applied right rudder to correct the veer, but the airplane subsequently ground-looped to the left. The right main landing gear collapsed, and the right wing and right horizontal stabilizer struck the ground. The airplane sustained substantial damage to the right wing, right horizontal stabilizer and fuselage. The pilot indicated that there were no preaccident mechanical problems with the airplane. The pilot elected not to complete and submit an NTSB form 6120.1 as requested. ## Aircraft - Registration: [N378X](https://openairdocs.org/deregistered/N378X-2018-05-30), registration cancelled 2018-05-30, S/N 6178C, built 1976 (OpenAirDocs) - Reported make and model: MAULE M-5-210C - Registry model: [Maule M-5-210C](https://openairdocs.org/model/maule-m-5-210c) (registry code 5460134) (OpenAirDocs) - Registry engine: [Continental IO-360 series](https://openairdocs.org/engine/continental-io-360-series) (registry code 17025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 6178C - Engines: CONT MOTOR IO-360 SER 210 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pending - Registered owner: Pending - Airworthiness certificate: Standard, Normal - Departed: PAJN, Juneau, AK - Destination: PAJN, Juneau, AK - Flight plan: Unknown - Airport: PAJN, Juneau International, runway 26, 8,457 × 150 ft, asphalt ## Flight crew As NTSB recorded them.
