The NTSB's narrative final · quoted from the NTSB record
The pilot said that as they raised the landing gear on takeoff, and the right main landing gear (MLG) door did not retract. He said that the checklist instructed him to cycle the landing gear; when he cycled the landing gear, the right MLG became jammed in the half down position. The pilot performed a low fly-by, and maintenance personnel on the ground photographed the bottom of the airplane. Gulfstream Aerospace engineers reviewed the photograph and advised the pilot in how to extend the landing gear. The pilot was then able to extend the landing gear. Six hours and ten minutes after takeoff, the airplane landed successfully. Post-incident examination of the right MLG revealed a black/rubber skid mark on the inside of the MLG door; the skid mark terminated at a row of 27 bolts which hold a gap seal in place. The outboard tire of the right MLG truck exhibited seven evenly spaced gouges which matched the spacing of the gap seal bolts. The MLG door uplock linkage bungee/actuator's (P/N 1159L50903-1) exterior exhibited advanced exfoliating corrosion.
