2006-06-01: DE Havilland DHC-3T (N606KA) — Port Townsend, WA

Port Townsend, WA, US

On June 1, 2006, a DE Havilland DHC-3T (registration N606KA) was involved in an aviation accident near Port Townsend, WA. Investigators recorded the probable cause as: The pilot's misjudgment of the airplane's height above the water during a precautionary landing which resulted in a hard landing. Contributing factors were glassy water conditions, fog, and the pilot's inadvertent VFR flight into IMC. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot executed a precautionary landing on glassy-smooth water after weather conditions deteriorated, misjudging altitude due to lack of visual definition. The hard landing caused fuselage and stabilizer damage.

Flight and Weather Conditions

The airplane was operating under a company-activated visual flight rules (VFR) flight plan over ocean waters. The pilot reported that weather conditions worsened, with a lowering ceiling and reduced visibility. He noted that the water surface was glassy smooth, offering no visual definition, which made it increasingly difficult to maintain forward visibility.

Pilot's Actions

Attempting to return to better VFR conditions, the pilot began a turn but conditions continued to deteriorate. He believed he inadvertently entered a fog bank. In response, he elected to perform a precautionary landing on the water.

Landing and Damage

During the landing, the pilot misjudged his altitude due to the lack of visual definition, resulting in a hard impact. The aircraft sustained significant structural damage: the fuselage was bent and deformed, the fuselage skin was wrinkled, and the dorsal stabilizer was bent and wrinkled.

Weather Observations

At 0655, weather conditions approximately 14 nautical miles north of the landing site reported calm wind, visibility of 7 statute miles with shallow fog, and cloud layers at 900 feet scattered, 2,000 feet scattered, 5,000 feet broken, and 20,000 feet broken. Temperature was 55°F, dew point 54°F, and altimeter setting 29.95 inches of mercury. The pilot reported that at the time of the attempted landing, visibility, wind, and ceiling were all zero.
