N168PT

Robinson R44 II

Analysis

The helicopter descended into the ocean after encountering instrument meteorological conditions. The accident helicopter was one in a flight of two helicopters on a cross-country positioning flight. Visual meteorological conditions prevailed at the departure airport; however, the flight crews encountered low ceilings at the destination airport and elected to continue the flight to the west, over water, in an effort to find a break in the overcast. A passenger in the number 2 helicopter (non-accident helicopter) reported the pilots of both helicopters were in continuous contact with one another during the flight and that as the weather conditions deteriorated, the pilot of the number 2 helicopter stated "I'm going to go through it" followed by "stay right behind me." The pilot in the accident helicopter agreed. The witness reported that when the number 2 helicopter entered the fog, the accident helicopter was "behind and above us." The witness stated the pilot in the accident helicopter radioed the pilot of the number 2 helicopter asking, "How fast are you descending?" The pilot stated "very slow." The witness reported that approximately 30 seconds later; the pilot of the number 2 helicopter stated, "Go back up... it's too low. It's much lower than we thought. Go back up right now." Radio contact with the accident helicopter was lost. Approximately 15 minutes later, two orange life vests and miscellaneous wreckage debris were found floating in the water approximately 1 mile offshore. The hourly METAR observation at the destination airport included, a visibility of 5 statute miles in mist, and overcast clouds at 400 feet. Search and rescue personnel reported the weather in the area of the accident was, visibility 1 mile; overcast ceiling at 100 feet and winds from the northwest at 10 knots.

Factual Information

HISTORY OF FLIGHT On August 13, 2006, about 0825 Pacific daylight time, a Robinson R44 II (Raven) helicopter, N168PT, impacted the ocean waters approximately 1 mile west of Camp Rilea, Warrenton, Oregon. The helicopter was destroyed and the three occupants, a private pilot seated in the front right seat (first pilot), a commercial pilot/flight instructor seated in the left front seat (second pilot) and passenger seated in the rear seat, were killed. Civic Helicopters of Carlsbad, California operated the helicopter, which was on a 14 CFR Part 91 positioning flight when the accident occurred. The flight departed Pearson Field Airport, Vancouver, Washington, about 0730 with an intended intermediate destination of Astoria, Oregon. Visual meteorological conditions prevailed at the departure airport and instrument meteorological conditions prevailed at the accident site. No flight plan was filed for the cross-country flight. The accident helicopter was one in a flight of two that departed Vancouver. The second helicopter was a Bell 206B Jet Ranger (N2183Y). Both helicopters were participating in "Flight of Discovery" to film a local event commemorating the Lewis and Clark expedition. The pilots planned to land in Astoria, Oregon, for fuel and then continue to Long Beach, Washington. In a written statement to the National Transportation Safety Board's Investigator-in-Charge, the pilot seated in the right seat of the Jet Ranger stated there was an overcast layer over Astoria when the two helicopters arrived, and they elected to continue the flight to the west, over water, in an effort to find a break in the overcast. The passenger seated in the aft seat of the Jet Ranger reported that the first pilot in the R44 was a recently certificated private pilot. The first pilot hired the second pilot to provide instruction during the flight as needed. The Jet Ranger flight crew consisted of two pilots, a private pilot seated in the right front seat, and a commercial pilot/certified flight instructor seated in the left front seat. The Jet Ranger passenger reported that the pilot in the right seat was manipulating the controls of the Jet Ranger when they departed Vancouver. However, later in the flight when the weather deteriorated, the pilot in the left seat assumed control of the helicopter. The Jet Ranger passenger also reported that the pilots of both helicopters were in continuous contact with one another during the flight and that as the weather conditions deteriorated, the second pilot in the accident helicopter queried the left seat pilot in the Jet Ranger as to what they should do with respect to the weather. The witness reported that the second pilot in the accident helicopter repeated the request a second time before receiving a response. The witness reported the left seat pilot in the Jet Ranger "took the controls" and stated "I'm going to go through it" followed by "stay right behind me." The second pilot in the accident helicopter agreed. The witness reported that when the Jet Ranger entered the fog, the accident helicopter was "behind and above us." The witness stated the second pilot in the accident helicopter radioed the left seat pilot asking, "How fast are you descending?" The Jet Ranger instructor pilot stated "very slow." The witness reported that approximately 30 seconds later; the instructor pilot of the Jet Ranger stated, "Go back up... it's too low. It's much lower than we thought. Go back up right now." The witness stated that as the Jet Ranger ascended, the left seat pilot attempted to contact the accident helicopter, however the attempts were unsuccessful and the Jet Ranger departed the area and landed in Astoria. After landing in Astoria, the instructor pilot in the Jet Ranger contacted emergency personnel via 911 and reported he had lost communications with the accident helicopter and believed that it had crashed. A search for the helicopter was initiated and about 0845 two orange "life vests" and miscellaneous debris were located floating in the water at N 46:07.499 and W 123:58.906. The bodies of both pilots and passenger were recovered in the general area later that day. Numerous smaller pieces of helicopter wreckage were recovered from the water, however a majority of the wreckage was not located. PERSONNEL INFORMATION Robinson R44 (Accident Helicopter) The pilot seated in the left seat of the R44 held a commercial pilot certificate with rotorcraft-helicopter and instrument ratings. The pilot also held a flight instructor certificate with helicopter and instrument helicopter privileges. The pilot seated in the right seat held a private pilot certificate with a rotorcraft-helicopter rating. The certificate was issued on May 10, 2006. Both pilots held current FAA medical certificates. Bell Jet Ranger The pilot seated in the right seat of the Jet Ranger held a private pilot certificate with a rotorcraft-helicopter rating. The pilot in the left seat held, among other certificates and ratings, a commercial pilot certificate with rotorcraft-helicopter and instrument ratings. The pilot also held a flight instructor certificate with helicopter and instrument helicopter privileges. Both pilots held current FAA medical certificates. AIRCRAFT INFORMATION The 2005 model R44 II helicopter, S/N 10775, was powered by a 245-horsepower Lycoming IO-540 engine, which drove a two bladed main rotor system and a two bladed tail rotor. An instrument flight training avionics package, that included a Gamin GNS 430 global positioning system, was installed in the helicopter. The helicopter was not certified for flight in instrument meteorological conditions. The helicopter's last 100-hour inspection was completed on July 18, 2006. The aircraft had accrued approximately 40 hours between the inspection completion date and the time of the crash. The operator reported no open maintenance discrepancies with the helicopter at the time of the accident. METEOROLOGICAL INFORMATION The 0755 hourly METAR observation at Astoria was, in part, visibility 5 statute miles and mist, overcast clouds at 400 feet, temperature 13 degrees C; dew point 12 degrees C. At 0905 Coast Guard search and rescue (SAR) personnel reported the weather one mile west of Camp Rilea was, in part, visibility 1 mile; overcast ceiling at 100 feet and winds from the northwest at 10 knots. MEDICAL AND PATHOLOGICAL INFORMATION A postmortem examination of both pilots was conducted on August 14, 2006. According to the postmortem reports, the cause of death for both pilots was attributed to multiple blunt force injuries. The manner of death, in both cases, was listed as accidental. Toxicology testing on both pilots was conducted by the FAA's Forensic Toxicology Research Team, Oklahoma City, Oklahoma. Both pilots tested negative for carbon monoxide, cyanide, ethanol and a wide range of drugs, including drugs of abuse. The final forensic toxicology report, which includes specific test parameters and results, is contained in the public docket for this case. ADDITIONAL INFORMATION Based on the available evidence, it could not be determined whether the first or second pilot was flying the helicopter at the time of the accident. The recovered wreckage was released to a representative of the owner on February 21, 2007.

Probable Cause and Findings

The pilot's intentional flight into instrument meteorological conditions while maneuvering which resulted in an in flight collision with terrain/water.
