Factual Information

HISTORY OF FLIGHT On June 25, 2003, at an estimated time of 1550 Alaska daylight time, a single engine, tundra tire-equipped Cessna 180 airplane, N91303, is presumed to have collided with the ocean waters of the Cook Inlet, about 7 miles southwest of Anchor Point, Alaska. No wreckage has been located, and the airplane is presumed to be destroyed. A fatally injured passenger was located on July 3, in ocean waters near Anchor Point. The airline transport certificated pilot, and the remaining passenger, were not located and are presumed to have received fatal injuries. The airplane was being operated as a visual flight rules (VFR) on-demand passenger flight under Title 14, CFR Part 135, when the accident occurred. The airplane was operated by Hallo Bay Air Inc., Palmer, Alaska. The accident flight originated from Hallo Bay, located on the eastern shore of the Alaska Peninsula, about 1430, for a flight to Homer, Alaska, located on the Kenai Peninsula. Visual meteorological conditions prevailed at Hallo Bay and at Homer. A VFR flight plan was filed, with an expected time of arrival in Homer of 1600. The Federal Aviation Administration (FAA) reported that earlier in the day, the pilot departed Homer and opened his flight plan at 1217 for a round-robin flight to the Hallo Bay Wilderness Camp, located within the Katmai National Park, about 100 miles south-southwest of Homer. The camp is located about 63 miles west-northwest of Kodiak, Alaska. On the pilot's flight plan, he indicated the expected route for the return flight was Hallo Bay, Cape Douglas, Augustine Island, Anchor Point, and then Homer. The airplane was observed to depart Hallo Bay for the return flight. The airplane did not arrive in Homer, and the FAA declared the flight overdue on June 25, at 1802. During search operations, search personnel learned the pilot verbally indicated to another pilot at Hallo Bay, a possible return route of Hallo Bay, Cape Douglas, Barren Islands, the lower end of the Kenai Peninsula, and then to Homer. The Barren Islands are about 27 miles east-northeast of Cape Douglas. The southern end of the Kenai Peninsula is about 13 miles north-northeast of the Barren Islands. No wreckage was located and the search was suspended on July 2, 2003. A fishing vessel spotted the passenger in the water on July 3. The passenger was not wearing a personal floatation device. No other debris was found. PERSONNEL INFORMATION Pilot Information The pilot held an airline transport pilot certificate with an airplane multiengine rating, a flight engineer certificate with a jet rating, commercial pilot privileges with airplane single-engine land, and airplane single-engine sea ratings, and airplane type ratings in B-727, B-747, and DC-10 airplanes. In addition, the pilot held a flight instructor certificate with an airplane single-engine rating. The pilot's previous first-class medical certificate was issued on November 29, 2001. In November 2002, the pilot was treated for coronary artery disease, and underwent surgery for a single vessel coronary artery bypass grafting. In the application for the pilot's most recent medical certificate, dated May 1, 2003, the pilot reported his treatment for coronary artery disease and surgery to the FAA's Alaska Regional Flight Surgeon. After a review of the pilot's medical information, the flight surgeon subsequently issued the pilot a second-class medical certificate on May 1, 2003, with a limitation that the pilot must wear lenses for distant vision, and possess glasses for near vision. In addition, the pilot's medical certificate had a restriction stating his certificate was not valid after July 31, 2003. No personal flight records were located for the pilot. On the pilot's application for medical certificate, dated May 1, 2003, the pilot indicated that his total aeronautical experience consisted of about 35,000 hours, of which 18 were accrued in the previous 6 months. Company Information The pilot held a single-pilot air taxi certificate. His primary flight operations were conducted between Homer and Hallo Bay Wilderness Lodge. AIRCRAFT INFORMATION Examination of the maintenance records revealed that the most recent annual inspection was accomplished on January 16, 2003. At that time, the airplane had accrued 3,464.3 hours, with a tachometer reading of 292.0. On July 6, 1998, a zero-time, rebuilt IO-520F engine was modified to a Texas Skyways O-520F/TS configuration by the installation of a carburetor, and then installed in the airplane. At that time, the airplane had accrued 3,171.37 hours, with a tachometer reading of zero. On May 9, 2003, with a tachometer reading of 294.14, the engine was again modified by removal of the carburetor and installation of a Bendix fuel injection system. The most recent maintenance record entry for the engine was an oil change at a tachometer reading of 340.53. The date was not specified.
