Incident Overview
An aircraft experienced difficulties with elevator pitch control during the climb phase of flight after departing Reno. The aircraft had been on the ground for 36 minutes during a period of rain and wet snow. Following takeoff, as the aircraft climbed through below-freezing temperatures, the crew encountered problems controlling the elevator pitch. These difficulties continued until the aircraft began its descent into Seattle.
Post-Flight Examination
After landing, a detailed inspection of the elevator assemblies was conducted. The examination revealed the presence of water within the inboard section of both elevator assemblies. Additionally, sealant material was found to be missing from the upper surface of the left elevator panel. The combination of water ingress and missing sealant may have contributed to the control difficulties experienced during flight.
