The airline transport certificated pilot was preparing to land a multiengine, retractable gear airplane, and as he lowered the landing gear, he did not receive a cockpit indication that the right main landing gear was extended. The pilot performed the emergency gear extension procedures, including the use of the emergency blow-down system, but the right main gear failed to extend. The pilot then landed with the left main landing gear and nose gear extended, and during the landing roll, shutdown the right engine. As the airplane slowed, the right wing and fuselage contacted the runway surface. A postaccident examination of the airplane revealed scraping/scuffing damage to the underside of the right wing and aileron. The right main landing gear strut was fully compressed. The gear extension and retraction components appeared to be undamaged. The operator's maintenance personnel reported that proposed repairs to the airplane included removal and replacement of the right wingtip, aileron and flap, and patching of fuselage skin. An FAA inspector reported that during further examination of the landing gear, the right gear hydraulic actuator was found contaminated with water. The temperature at the accident location was -2 degrees F. The FAA inspector indicated the actuator was probably frozen.
Probable Cause: Water contamination and freezing of the landing gear actuator that prevented the extension of the right main landing gear, resulting in a gear-up landing. Factors contributing to the accident were freezing temperatures at the accident location, and inadequate maintenance/servicing of the landing gear system by company maintenance personnel.
