NTSB Factual Report

On July 26, 2016, at 1509 central daylight time, an Embraer EMB-505 airplane, N362FX, was substantially damaged during a runway excursion on landing at the Sugar Land Regional Airport (SGR), Sugar Land, Texas. The two pilots sustained minor injuries; the sole passenger was not injured. The airplane was registered to FlexJet LLC and operated by Flight Options LLC under the provisions of 14 Code of Federal Regulations Part 135 as a corporate/executive flight. Visual meteorological conditions were reported at the airport; however, instrument meteorological conditions prevailed in the local area. The flight was operated on an instrument flight rules flight plan. The flight originated from the Scottsdale Airport (SDL), Scottsdale, Arizona, at 1029 mountain standard time.

The pilot-in-command reported that he flew an instrument landing system (ILS) approach to runway 35 (8,000 feet by 100 feet, concrete) and then transitioned to a visual approach. The approach and landing were normal; however, after touchdown the brakes seemed ineffective. He subsequently activated the emergency brake at which time the airplane started to slide. The airplane ultimately departed the end of the runway and encountered a small creek before coming to rest.
