Probable cause & findings
FAILURE OF THE RIGHT MAIN LANDING GEAR DOOR ACTUATOR.
Factual narrative
DURING CLIMB, THE RIGHT MAIN LANDING GEAR DOOR ACTUATOR AND THE MAIN LANDING GEAR DOOR SEPARARTED FROM THE AIRPLANE. THE DOOR ACTUATOR COLLIDED WITH A RESIDENCE, PASSING THROUGH THE ROOF AND LODGING IN THE CEILING. DURING THE RETURN FLIGHT TO CHICAGO, THE AIRPLANE EXPERIENCED TOTAL HYDRAULIC PRESSURE AND FLUID LOSS, BUT LANDED WITHOUT INCIDENT. BOTH THE OPERATING GLAND HOUSING AND SHAFT, AND THE ACTUATOR ROD END OF THE RIGHT MAIN GEAR DOOR HAD FRACTURED. METALLUGICAL EXAMINATION OF THE GLAND SHAFT FRACTURE REVEALED BEACH MARKINGS AND OTHER SURFACE FEATURES THAT IN THE MOST PART WERE TYPICAL OF UNIDIRECTIONAL BENDING FATIGUE PROGRESSION.
