Aviation Accident Summary WPR15LA089

Maui, PO, USA

Aircraft #1

N7YT

CIRRUS SR22 - NO SERIES

Analysis

The pilot reported that, during the transpacific flight, he was unable to transfer fuel from the aft auxiliary fuel tank to the main fuel tanks. Despite multiple attempts to troubleshoot the fuel system issue, he was unable to correct the situation. After transferring fuel from the forward auxiliary fuel tank to both main fuel tanks, he estimated that there was only enough fuel in the main tanks to reach within about 200 miles of land, so he decided to divert to a nearby cruise ship. Once the airplane was in the immediate vicinity of the cruise ship, the pilot activated the airplane's parachute system, the parachute deployed, and the airplane descended under the canopy into the ocean. The pilot immediately exited the airplane and inflated an emergency life raft; he was recovered from the water a short time later. The airplane subsequently became submerged in the water and was not recovered. The reason for the pilot's inability to transfer fuel from the aft auxiliary fuel tank to the main fuel tanks could not be determined.

Factual Information

On January 25, 2015, about 1644 Hawaiian standard time, a Cirrus Design Corporation SR22, N7YT, ditched into the waters of the Pacific Ocean about 230 miles east of Maui, Hawaii. The airplane was registered to Cirrus Design Corporation, Duluth, Minnesota, and operated by The Flight Academy, Kirkland, Washington, under the provisions of Title 14 Code of Federal Regulations Part 91. The commercial pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed for the repositioning flight. The cross-country flight originated from Tracy, California, about 0530, with an intended destination of Maui.In a written statement to the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot reported that the flight was uneventful, and a previous fuel transfer from the front and aft auxiliary fuel tanks was successful as the flight was about 200 miles offshore. However, as the flight passed the BILLO intersection, the pilot opened the valves to transfer fuel from the aft auxiliary fuel tank to the right wing fuel tank and did not observe any fuel flow. Upon verifying that the pressure line was open, he closed the valve to the aft tank and opened the valve for the forward auxiliary fuel tank, and observed that fuel immediately began flowing to the right wing fuel tank. The pilot further stated that as he was well past the half-way point to Hawaii, he performed various maneuvers in an attempt to get fuel to flow from the aft auxiliary fuel tank to either the left or right main wing fuel tanks with no success. The pilot utilized a satellite phone and obtained further troubleshooting assistance from company personnel. After transferring fuel from the forward auxiliary fuel tank to both left and right wing fuel tanks, he estimated that he had about enough fuel onboard to be about 200 miles short of Hawaii. The pilot stated that numerous attempts to transfer fuel from the aft auxiliary fuel tank to the main fuel tanks were unsuccessful, and siphoning fuel from the aft auxiliary to the forward auxiliary fuel tank was partially successful, however, eventually fuel would not transfer into either wing fuel tank. While in contact with the United States Coast Guard, the pilot made the decision that he would eventually have to deploy the Cirrus Airframe Parachute System (CAPS). The pilot was informed of a cruise ship near his location, and subsequently diverted towards that location. He further reported that once he was in the immediate vicinity of the cruise ship, he activated the CAPS and the parachute deployed. The airplane descended under the canopy into the waters of the Pacific Ocean. The pilot stated that he immediately exited the airplane and inflated an emergency life raft; he was extracted from the water a short time later. The airplane became submerged within the water shortly thereafter. At the time of this report, there is no intention of recovering the wreckage.

Probable Cause and Findings

The pilot's inability to transfer fuel from the aft auxiliary fuel tank to the main fuel tanks for reasons that could not be determined because the airplane was ditched and not recovered.
