He indicated that those brakes with moderate wear had a tendency to grab and lock up. He went on to say that there has been a history of problems with the stearman brake system. privacy data omitted An airworthiness inspector inspected the disassembled brakes and noted moderate wear on the brake shoes and areas on the shoes that were glossed over with brake dust and dirt. privacy data omitted The pilot's privacy data omitted performance as described to me does not warrant a reexamination of his pilot certificate.
