Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The noncertificated pilot was flying the helicopter at an altitude of 40 to 50 feet. The pilot commented to the passengers that he was concerned about the amount of fuel remaining onboard, then the helicopter impacted the water. Although the pilot reported a flashing light on the control panel and a buzzer indicating there was a problem with the helicopter, neither passenger reported seeing any warning lights or hearing any alarms before the impact. According to Robinson Helicopters, the aural warning is loud enough that anyone in the helicopter would hear it. A postaccident inspection revealed that both fuel tanks were empty but it could not be determined if the fuel lines were intact. Both passengers reported drinking alcohol prior to the accident and the passengers provided conflicting reports to local authorities as to whether the pilot had consumed alcohol prior to the flight. The pilot was taken to his father’s residence immediately following the accident, prior to the arrival of local authorities. The pilot subsequently refused to speak with the local authorities when they arrived at the residence. Multiple cans and bottles of beer were recovered from the accident site. The pilot’s attorney reported that there was no reason to believe there was a failure or malfunction of the helicopter airframe or its engine prior to the impact.

Factual narrative

On September 30, 2012, at 1845 central daylight time, a Robinson Helicopter R44, N8341W, impacted Lake Nocona, Nocona, Texas. The non-certificated pilot and one passenger received minor injuries. A second passenger was not injured. The helicopter was substantially damaged. The helicopter was registered to the pilot and was being operated under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The flight originated from Montague, Texas, about 1745. The non-certificated pilot reported to a Texas Parks and Wildlife officer that they were flying over the lake when the helicopter suffered a “complete engine failure.” He stated that a buzzer was sounding and a flashing light on the control panel was illuminated indicating there was a problem with the helicopter. The helicopter then struck the water. All three occupants were able to exit the helicopter and they were picked up by a boat and transported to the shore. Following the accident, prior to the arrival of local authorities, the pilot had friends take him to his father’s home where he refused to speak with local authorities. The two passengers were transported to the hospital. One of the passengers stated to the National Transportation Safety Board (NTSB) that he and the other passenger drove to a friend's house earlier in the day, and that the pilot flew the helicopter to this same friend’s house where he landed. He stated that he consumed about 6 beers. He stated that he did not see the pilot consume any alcohol; however, in a statement to local authorities he stated "they had all been hanging out together and drinking beer before they loaded up in [the pilot's] helicopter." The passenger stated he was seated in the right rear seat during the flight. He stated they flew around for about one hour and they were at an altitude of 40 to 50 above the lake just prior to the accident. He stated that the pilot mentioned that they needed to head back in order to have enough fuel to drop the passengers off in Montague and get back to the airport. This passenger stated that he did not hear any warning alarms in the helicopter prior to impacting the water, but that something did sound different to him prior to impact. The other passenger who was seated in the front of the helicopter stated to local authorities that he consumed about six beers prior to the flight and he estimated that the others drank about the same. He stated that he did not hear any “buzzers” sounding or lights flashing inside the helicopter prior to it impacting the water. The non-certificated pilot did not provide a statement to either the NTSB or the Federal Aviation Administration (FAA); however, the pilot's attorney did provide a statement that he spoke with the pilot and there was no reason to believe that there was a failure or malfunction with either the helicopter or the engine. According the FAA, thepilot was issued a third-class airmen medical certificate in 2008. The medical certificate was subsequently revoked due to falsification of records. A postaccident inspection of the wreckage revealed that the right fuel tank was intact, but was partially pulled away from the fuselage. The left fuel tank was intact and it remained attached in place. Both fuel tanks were empty. It was not determined if the fuel lines from the tanks to the engine were compromised. Local authorities reported that multiple cans and bottles of beer were recovered as they floated out from the wreckage.
