What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On July 12, 2006, at 1510Z, a Lear model 31A, N569SC, on approach to southern Wisconsin regional airport, Janesville, WI, experienced a hard roll to the right when the flaps were lowered to 8 degrees. Opposite aileron input did not correct roll. The flaps were retracted and normal flight was resumed. The crew performed a go around and made a no flap landing without incident. Investigation on the ground revealed the right flap inboard nose roller separated from the flap structure. As a result, the flap, when lowered shifted outboard contacting the right aileron and restricting aileron travel. The aircraft was being operated as a repositioning ferry flight by SC aviation, inc. under 14 CFR part 135 when the incident occurred. Visual meteorological conditions prevailed at the time.
