On November 20, 2013, at 1030 eastern standard time, a Beech C90A, N702DK, was substantially damaged during a landing gear collapse after a precautionary landing at Roanoke Regional Airport (ROA), Roanoke, Virginia. The pilot, copilot, and the two passengers were uninjured. Visual meteorological conditions prevailed, and no flight plan was filed for the air taxi flight conducted under Title 14 Code of Federal Regulations Part 135 which departed Chesterfield County Airport (FCI), Richmond, Virginia, originally destined for Montgomery Executive Airport (BCB), Blacksburg, Virginia.
According to the pilot, after departing FCI for BCB, the flight was uneventful until the landing gear was lowered while on the downwind leg of the traffic pattern for runway 12 at BCB, when the pilot realized that the right main landing gear was not down and locked in position for landing. The landing gear annunciator panel indicated that both the nose landing gear and left main landing gear were in the proper position but, the right main landing gear "green light" was not illuminated.
The pilot and copilot then tested the light to ensure that it was operating properly and it illuminated when pressed. The landing gear "handle" was then moved to the up position with no change in the landing gear position indication. It was then was placed back into the "down" position with no change in indication. At this point the pilot decided to abort the landing.
Further attempts to extend the right main landing gear were unsuccessful and the pilot made a decision to divert to ROA since the runways were longer than the ones at FCI or BCB. After executing the manual gear extension checklist the flight crew made a low pass down runway 24 at ROA and the air traffic controller who was in the control tower advised that from his vantage point it appeared the landing gear appeared to be in the down position. The pilot then made a decision to land without flaps and to shutdown the right engine and feather the propeller to minimize damage should the right main landing collapse.
During the landing the touchdown was normal and no "abnormal feelings" were observed. After applying the brakes and adding reverse thrust on the operating engine the airplane slowed normally however as the airplane exited the runway the right main landing gear collapsed.
Post accident examination of the airplane revealed that the right main landing gear actuator support bracket was broken and had separated from its mounting position. Further examination revealed the presence of discoloration on its mounting surfaces around the fasteners on the outboard side of the support bracket which attached it to the airplane's structure.
The right main landing gear actuator support bracket, and portions of the right main landing gear assembly were retained by the NTSB for further examination.
