The commercial pilot sustained minor injuries. The airplane was operated as a Title 14?Code of Federal Regulations Part 91 special flight for the purpose of production flight test. The pilot stated that the first two landings of the day with this airplane were uneventful, but on the third landing the left master cylinder failed while in a two-wheel landing configuration with the tail coming down. The airplane then swerved to the right at high speed. During the departure from the runway, the left tire came off of the rim which then dug into the runway surface followed by the dirt off of the runway, causing the tail of the airplane to pivot around the left main landing gear. Because of the side load force applied, the left main gear separated from the airplane during the ground loop. The propeller and left wing contacted the ground, and the airplane came to a stop. He then shut down and secured the airplane. Three days earlier during a production flight test in the same airplane, after touchdown the left brake master cylinder failed causing the airplane to depart the runway, resulting in only damage to the left main landing gear tire. That incident was not reported to NTSB at the time and was not investigated. ## Sequence of events The events NTSB coded, in order, by phase of flight.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
