Incident Description
The pilot, who held an airline transport certificate, was preparing to land a multiengine, retractable gear airplane. Upon lowering the landing gear, the cockpit provided no indication that the right main landing gear had extended. The pilot executed the emergency gear extension procedures, which included activating the emergency blow-down system, but the right main gear remained retracted.
Subsequently, the pilot landed the airplane with only the left main landing gear and nose gear extended. During the landing roll, the pilot shut down the right engine. As the airplane decelerated, the right wing and fuselage contacted the runway surface.
Postaccident Examination
A postaccident examination of the airplane revealed scraping and scuffing damage to the underside of the right wing and aileron. The right main landing gear strut was found fully compressed. The gear extension and retraction components appeared undamaged.
The operator's maintenance personnel reported that proposed repairs to the airplane included removal and replacement of the right wingtip, aileron, and flap, as well as patching of the fuselage skin.
Further Findings
An FAA inspector reported that during a subsequent examination of the landing gear, the right gear hydraulic actuator was found contaminated with water. The temperature at the accident location was -2 degrees Fahrenheit. The inspector indicated that the actuator was probably frozen.
