Location: Chino, CA
Accident Number: GAA19CA493
Date & Time: 08/10/2019, 1254 PDT
Registration: N6432D
Aircraft: North American AT 6D
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot reported that, during his ninth touch and go, shortly after touchdown, the airplane bounced. He wanted to apply partial power and continue to land but he heard the safety pilot declare, "I have," the pilot response, "you have", and gave up controls to the safety pilot. Shortly after, the airplane rolled to the right, the right wing struck the ground, the airplane exited the runway and impacted terrain.

The safety pilot reported that during landing, the left main landing gear touched down on the runway first, followed by the right main landing gear, and the airplane "popped up" with a nose high attitude. The airplane started to climb, continued to pitch higher and rolled to the right, so he "took" controls, applied power, and lowered the nose, but the right-wing tip struck the ground and the airplane impacted terrain.

The airplane sustained substantial damage to the engine mount and truss.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

  1. 9 Touch and Goes???? That's enough mental fatigue for any pilot with only 34 hours in a new complex airplane. We're not 18 year old WWII trainees at 55 years of age!

  2. Hamamatsu Okamoto is a commercial pilot and Certified Flight Instructor with a residence and business in Shizuoka, Japan. When Okamoto visits the United States he is a private pilot.

    Certified Flight Instructor Yanagida plan was to invest to own and have training on T-6 Texan N6432D. Okamoto applied to join and accepted. The plan involved three people, CFI Yanagida, Mr. Matsumoto and Okamoto. Mr. Matsumoto would be ATP in Japan, not sure the status in Japan but never Certified Flight Instructor.

    Okamoto training started just one year before. Okamoto stayed in the United States about a week or less at once, 2018 August, December, 2019 February and August, it was fourth training period.

    After receiving CFI Yanagida's dual instruction of T-6, Okamoto performed training flights in front seat, with so-called safety pilot, Mr. Matsumoto, in rear seat. At start of Okamoto training, he insisted safety pilot not to take his control over, because he should be PIC, otherwise the responsibility could be uncertain in case of accident. But Yanagida and Matsumoto refused to accept Okamoto offer. CFI Yanagida said that he'll be responsible for everything, and requested to believe and follow him. So Okamoto followed their advice, in case safety pilot declare "I have", Okamoto reply "you have" and give all control to him and make no interference to the control. The flight should be Okamoto training, but who will be PIC? If no accident, PIC will be Okamoto. But what in case of accident? The accident happened in such situation.
