Analysis

During gear retraction after takeoff, the right main gear became jammed in a partially retracted psn & the respective in-transit gear light would not extinguish. Attempts to recycle the gear were unsuccessful. The flt crew diverted to atlanta, GA; then decided to land at Dobbins Afb, where there was a long, wide rwy that could be foamed. Foam was applied to aprx 300 ft of rwy 29. The acft was landed with the nose & left main gear extended & the right main gear partially retracted. Subsequently, the acft veered to the right & stopped with the nose gear aprx 70 ft off the rwy. Fire erupted in the area of the right main gear; however, the fire was quickly extinguished by fire dept personnel. An investigation revealed the clearance btn the main landing gear door hook, pn 803845-1, & the strut roller was excessive. The reason for the improper clearance was not determined. Lockheed service bulletin 88/SB-558 warned that excessive clearance combined with a drop in hydraulic pressure, gust or maneuver could result in the gear jamming.
