This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On June 4, 2013, about 1540 Alaska daylight time, a float-equipped de Havilland DHC-2 (Beaver) airplane, N616W, sustained substantial damage when it collided with mountainous, tree-covered terrain, about 14 miles east of Petersburg, Alaska. The airplane was being operated by Pacific Wings LLC, as a visual flight rules (VFR) sightseeing flight under the provisions of 14 Code of Federal Regulations, Part 135, when the accident occurred. The certificated airline transport pilot and three passengers sustained minor injuries, two passengers sustained serious injuries, and one passenger was fatally injured. Visual meteorological conditions prevailed, and company flight following procedures were in effect. The flight originated at the Lloyd R. Roundtree Seaplane Facility, at the Petersburg Harbor, Petersburg, about 1519.
The flight was a sightseeing flight for cruise ship passengers, and the passengers cruise ship was docked in Petersburg.
During an interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on June 6, the pilot stated that the accident flight was his fourth flight of the day, and his third tour flight that day. He said that weather conditions had deteriorated throughout the day with a ceiling of approximately 2,000 feet, light rain, and fog along the mountain ridges. He had departed from the Petersburg harbor en route to LeConte Glacier, via Horn Cliffs. He reported that while attempting to transit a mountain pass en route to LeConte Glacier, he initiated a left turn to avoid rising terrain and subsequently impacted the tree-covered terrain. The pilot stated that there were no preaccident mechanical anomalies that would have precluded normal operation.
As part of their company flight following procedures, Pacific Wings incorporates Spidertracks, which provides company management personnel with a real-time, moving map display of the airplane's progress. After returning from a flight, the director of operations for Pacific Wings was alerted that the flight track for the accident airplane had stopped transmitting along the anticipated route to LeConte Glacier. Unable to establish radio contact with the pilot, he initiated a search for the missing airplane.
About 1547, approximately 7 minutes after the accident, the United States Coast Guard (USCG) Alaska received a 406 Mhz emergency locator transmitter (ELT) signal assigned to the accident airplane.
At approximately 1614, after being notified of an overdue airplane, and after learning about reports of an emergency locator transmitter (ELT) signal along the accident pilot's anticipated flight route, search and rescue personnel from the U.S. Coast Guard Air Station Sitka, began a search for the missing airplane.
About 1816, the crew of a U.S. Coast Guard HH-60 helicopter located the airplane's wreckage in an area of mountainous, tree-covered terrain. A rescue swimmer was lowered to the accident site and discovered that one of the airplane's occupants died at the scene, and six others survived the crash. The six survivors were hoisted aboard the HH-60 helicopter, and then transported to Petersburg.
The NTSB IIC, along with an Alaska State Trooper, two volunteers from Juneau Mountain Rescue, and while being assisted by the United States Coast Guard, reached the accident site on the afternoon of June 5. The accident site was in an area of steep, heavily forested, mountainous terrain, at an elevation of about 912 feet mean sea level. The team was unable to perform an in-depth wreckage examination on scene due to the instability of the wreckage. A detailed wreckage exam is pending following recovery of the airplane.
The closest weather reporting facility was Petersburg Airport, approximately 14 miles west of the accident site. At 1536, an aviation routine weather report (METAR) at Petersburg, Alaska, reported wind, calm, visibility, 2 1/2 statute miles with light rain and mist, scattered clouds at 500 feet, broken clouds at 1,300 feet, overcast clouds at 1,800 feet, temperature, 52 degrees F; dew point 48 degrees F; altimeter, 30.03 inHG.
