On May 30, 2014, about 0930 Alaska daylight time, a de Havilland DHC-3T airplane, equipped with a Honeywell TPE331 turbine engine, experienced an anomalous in-flight vibration and uncommanded nose-down pitch during cruise flight in the vicinity of Homer, Alaska. The personal flight was operated by Alaska Air Taxi under the provisions of 14 Code of Federal Regulations Part 91 with no flight plan filed. The airline transport pilot and the two passengers were not injured, and the airplane sustained substantial damage to the right elevator. Visual meteorological conditions prevailed. The flight departed Seldovia, Alaska, about 0900, en route to Anchorage, Alaska.

According to the pilot, during cruise flight, the airplane vibrated and subsequently pitched nose-down. The pilot applied corrections and continued the flight to the destination. After landing, the pilot and a mechanic examined the airplane and found that the skin on the right elevator servo tab was separated from the hinge, and spar structures inside the right elevator were cracked.

The elevator servo tab skin and hinge were retained for further examination.
