According to track data recovered from a handheld GPS receiver found in the wreckage, the helicopter was on the final leg of a cross-country flight that had originated earlier in the day. According to fueling documentation, the helicopter was refueled, and the flight departed and proceeded on a southeast course toward the intended destination. According to the plotted GPS data, while enroute, about 600 feet above ground level (agl), the helicopter entered a descending left turn to an east-northeast course. About 30 seconds later, after descending about 100 feet, the helicopter entered a climb while on a northeast heading. During the climb, the helicopter's groundspeed decreased from 73 knots to 27 knots. The final GPS data point, recorded about 1 minute after the initial turn from the intended course, showed the helicopter about 800 feet agl at 27 knots groundspeed and about 0.2 mile north-northwest of the accident site. The helicopter wreckage was located in a sparsely populated area with hilly terrain. The debris path was orientated on a south-southeast heading, and the length and distribution of the debris path were consistent with the helicopter impacting rising terrain at cruise speed. Postaccident examination of the helicopter revealed no evidence of a preimpact failure or malfunction that would have precluded normal operation. A postaccident review of meteorological data established that marginal visual flight rules conditions likely existed in the vicinity of the accident site at the time of the accident. The weather data supported increasing low-level cloud development and scattered light rain showers. No strong outflow winds or severe storm signatures were associated with the observed rain showers. The accident flight was conducted in dark nighttime conditions with minimal illumination from ground light sources. The helicopter's flight path during the last minute of GPS data was consistent with the pilot becoming spatially disoriented due to the lack of a discernible horizon that he could use to maintain control of the helicopter. Although the helicopter was equipped with basic attitude instrumentation and avionics, it was not certified for flight under instrument flight rules (IFR). Additionally, although the pilot held an instrument rating for helicopters, his IFR currency could not be verified from available logbook data. According to FAA correspondence, about 5 months before the accident, the FAA had notified the pilot that he was ineligible to hold any class of medical certificate because of his multiple alcohol-related offenses. Although he had been advised multiple times of his ineligibility to hold a medical certificate, flight documentation established that the pilot continued to exercise the privileges of his commercial and flight instructor certificates. Toxicological test results for the pilot were negative for carbon monoxide, cyanide, ethanol, and all drugs and medications. The helicopter operator reported that the accident occurred during an instructional flight; however, a review of available evidence did not support that the front-seat passenger was receiving flight instruction on the accident flight. According to FAA records, the front-seat passenger had never applied for a student pilot certificate or an aviation medical certificate. Additionally, a pilot logbook was not recovered during the investigation for the front-seat passenger. According to a business associate of both passengers, the front-seat passenger had coordinated the flight to attend a business appointment. According to photographs recovered from the front-seat passenger's mobile phone, on earlier flight legs, he had been seated in the left front seat. According to the helicopter manufacturer, the flying pilot typically would be seated in the right front seat, especially during initial flight instruction. Additionally, a review of the front-seat passenger's mobile phone established that he had been exchanging text messages with a business colleague in the minutes preceding the accident. Specifically, the final outgoing text message was sent about 26 seconds before the helicopter deviated from the direct course toward the intended destination. Therefore, it is unlikely that the passenger was operating the helicopter at the time of the accident.
HISTORY OF FLIGHTOn October 11, 2012, about 1958 central daylight time, a Robinson Helicopter Company model R44 II, N474FA, was substantially damaged when it collided with terrain during cruise flight near Blanco, Texas. The pilot and two passengers were fatally injured. The helicopter was operated by Veracity Aviation LLC, under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. Night visual meteorological conditions prevailed for the flight that departed Gillespie County Airport (T82), Fredericksburg, Texas, about 1942, and was en route to Huber Airpark Civic Club LLC Airport (E70), Seguin, Texas. According to recovered GPS data, the roundtrip cross-country flight, from the operator's home base at E70, located in Seguin, Texas, to Midland International Airport (MAF), in Midland, Texas, originally departed at 1241. The helicopter landed at MAF about 1503. According to fueling documentation, the accident helicopter was fueled with 37.7 gallons of 100 low-lead aviation fuel before the return flight. The return flight departed MAF at 1735 and landed at T82 to refuel about 1936. There were no witnesses to the helicopter arriving at T82 nor while it was being refueled at the self-serve fueling stations. According to fueling documentation, at 1936, the accident helicopter was fueled with 15.92 gallons of 100 low-lead aviation fuel. According to GPS data, the flight departed T82 at 1942. A witness, who was also a helicopter pilot, reported seeing a Robinson R44 helicopter depart toward the southeast; however, due to the dark night conditions he was unable to discern the helicopter's registration number or paint color. He noted that the helicopter had departed from the self-service fueling station near the main airport building. The plotted GPS data indicated that the flight proceeded on a southeast course toward the intended destination (E70). According to the data, the helicopter maintained an average ground speed of about 80 knots while in cruise flight. At 1956:50 (hhmm:ss), the helicopter entered a descending left turn from a southeast course to an east-northeast course. The helicopter was at 2,517 feet GPS altitude, about 610 feet above ground level, and had a ground speed of 72 knots when it entered the descending left turn. At 1957:19, the recorded GPS altitude was 2,396 feet, about 500 feet above ground level, and the helicopter's ground speed was 73 knots. The helicopter then began to climb on a northeast heading. The GPS data indicated that, during the climb, the helicopter's ground speed decreased from 73 knots to 27 knots. The final GPS data point associated with the accident flight was recorded at 1957:49 and a GPS altitude of 2,643 feet, about 800 feet above the terrain, with a ground speed of 27 knots. The final data point was located about 0.2 miles north-northwest of the accident site. At 2006, the United States Air Force Rescue Coordination Center (AFRCC), located at Tyndall Air Force Base, Florida, received a 406 MHz emergency locator transmitter (ELT) signal assigned to the accident helicopter. About 18 minutes later, the AFRCC was received their first of several triangulated positions for the active ELT signal. The accident site was subsequently located, with the assistance of airborne and ground units, at 0824 the morning following the accident. The wreckage was located in a sparsely populated area that was comprised of hilly terrain. PERSONNEL INFORMATIONAccording to Federal Aviation Administration (FAA) records, the pilot, age 35, held a commercial pilot certificate with helicopter and instrument helicopter ratings. He also held a flight instructor certificate with helicopter and instrument helicopter ratings. His last aviation medical examination was completed on March 31, 2011, when he was issued a second-class medical certificate without limitations. The pilot's flight history was reconstructed using a partially completed pilot logbook, a spreadsheet flight history that was provided by the pilot's employer, and GPS flight data that was recorded on the day of the accident. A review of the pilot's flight logbook revealed that his last recorded flight was completed on May 24, 2012. At that time, he had accumulated 1,410.9 hours total flight experience, of which 1,348.1 hours were listed as pilot-in-command. All of his logged flight time had been completed in helicopters. He had accumulated 63.6 hours in simulated instrument conditions and 109.5 hours at night. According the spreadsheet flight history, the pilot had flown an additional 111.7 hours since his final logbook entry. According to recovered GPS data, the pilot had flown 4.7 hours on the day of the accident. The pilot's total flight experience was estimated to be about 1,527.3 hours, of which 543.7 hours were completed in the same make/model as the accident helicopter. He had accumulated 1,464.5 hours as pilot-in-command and 644.4 hours as a flight instructor. He had accumulated 422.6 hours during the past year, 149.4 hours during the prior 6 months, 95.0 hours during previous 90 days, and 27.4 hours in the last 30 days. The pilot had flown 5.6 hours within the 24 hour period before the accident. The pilot's employer, Veracity Aviation LLC, provided flight instruction, local air tours, on-demand air taxi services, and external load operations. The accident pilot was employed as a flight instructor and assistant chief pilot for their 14 CFR Part 141 flight school. According to FAA documentation, on November 7, 2011, the pilot demonstrated the skill and knowledge to operate as pilot-in-command for external-load helicopter operations. On November 8, 2011, the pilot passed a FAA regulatory checkride to become an assistant chief pilot for the 14 CFR Part 141 flight school. The pilot was not authorized to act as pilot-in-command for Veracity Aviation LLC's on-demand air taxi service under 14 CFR Part 135. On March 15, 2012, the pilot received a letter from the FAA Aerospace Medical Certification Division informing him that he was not eligible to hold any class of medical certificate because of multiple alcohol related offenses. The pilot had two arrests that were associated with driving while intoxicated (DWI). The first arrest, dated October 16, 2004, resulted in a DWI conviction. The second arrest, dated November 18, 2011, was not prosecuted by the State of Texas as a DWI offense. On March 19, 2012, the pilot replied to the FAA letter, stating that he intended to work with the FAA to regain his eligibility to hold a medical certificate. The pilot also wrote that he had included his current medical certificate with the correspondence; however, FAA documentation indicated that the pilot had not included his medical certificate with his response. On March 27, 2012, the FAA replied to the pilot in the form of another letter that identified the specific regulations by which his eligibility to hold a medical had been revoked. The FAA response also detailed what documentation was required to be sent to the Aerospace Medical Certification Division for additional review before his eligibility could be reconsidered. On June 25, 2012, the pilot replied to the FAA in the form of another letter in which he described the circumstances of both alcohol related driving arrests. He wrote that he continued to provide "ground instruction" to his former students. Additionally, the pilot wrote that the State of Texas had declined to prosecute the November 2011 arrest for the charge of driving while intoxicated; however, he had pleaded not-guilty to the charges of speeding and being in possession of an open alcoholic beverage while operating a motor vehicle. On October 9, 2012, the FAA sent another letter to the pilot that reiterated his ineligibility to hold a medical certificate until all of the previously requested documentation had been received and reviewed by the Aerospace Medical Certification Division. (The pilot had not received the latest correspondence from the FAA Aerospace Medical Certification Division when the accident occurred) The owner of Veracity Aviation LLC told the NTSB investigator that although he knew of the pilot's November 2011 arrest, he was unaware that the FAA had revoked his medical certificate. Additionally, he was unaware that the pilot had been working with the FAA to reestablish his eligibility to hold a medical certificate. According to flight documentation provided by Veracity Aviation LLC and the pilot's personal logbook, the pilot had accumulated 218.1 hours since March 15, 2012, when he received the initial letter from the FAA Aerospace Medical Certification Division notifying him of his ineligibility to hold a medical certificate. Additionally, the flight records indicated that the pilot continued to act as pilot-in-command and as a flight instructor during the same time period. (Federal regulation 14 CFR Part 61.23 required a flight instructor to hold at least a third-class medical certificate if they acted as the pilot-in-command of any instructional flight) AIRCRAFT INFORMATIONThe accident aircraft was Robinson Helicopter Company model R44 II, serial number (s/n) 12517. The helicopter was a four-seat, single-engine helicopter that was equipped with a skid type landing gear. The FAA type certificate required one flight crew member (pilot) and permitted operations under day or night visual flight rules (VFR). Although the cockpit was equipped with flight attitude instrumentation and avionics, the accident helicopter was not certified for flight under instrument flight rules. The helicopter was equipped with dual cyclic controls and anti-torque pedals located at both the right and left cockpit positions. The helicopter was powered by a 245-horsepower Lycoming model IO-540-AE1A5, s/n L-33161-48E, reciprocating engine. The helicopter was issued a Standard Airworthiness Certificate on October 14, 2008. A review of the maintenance records revealed that the helicopter had undergone an annual inspection on October 3, 2012, at 993.5 hours total time. At the time of the accident, the airframe and engine had accumulated 1,003.0 hours in service. The helicopter had accumulated 9.5 hours since the last maintenance inspection. A review of maintenance documentation did not reveal any unresolved airworthiness issues. According to maintenance documentation, the accident helicopter had a basic empty weight of 1,530.5 pounds (lbs), a center-of-gravity location of 106.9-inches, and a useful load of 969.5 lbs. According to autopsy data, the pilot weighed 200 lbs, the front seat passenger weighed 325 lbs, and the rear seat passenger weighed 200 lbs. According to the Robinson R44 II Pilot Operating Handbook, the seats were limited to 300 lbs. According to GPS flight data and refueling documentation, the accident helicopter had about 36 gallons of fuel onboard when it departed on the accident flight. The additional personal property and cargo found onboard the helicopter weighed about 30 lbs. According to postaccident weight and balance calculations, the helicopter weighed about 2,501.5 lbs and had a center-of-gravity location of 91.85-inches when it departed on the accident flight. As such, at the time of departure, the helicopter likely exceeded the maximum gross weight limitation of 2,500 lbs and had a center-of-gravity located forward of the allowable limit. METEOROLOGICAL INFORMATIONAt 1900, a National Weather Service (NWS) Surface Analysis Chart depicted a low pressure system over eastern Kansas with a cold front extending southwest through Kansas and into the Oklahoma panhandle. A warm front extended southeast from the low into eastern Oklahoma and Arkansas. A high pressure region was located over Alabama. The resultant pressure gradient resulted in a general southeasterly wind flow that supported a warm moist air mass originating from the Gulf of Mexico. At 2000, the NWS Weather Depiction Chart depicted a small area of marginal visual flight rule (MVFR) conditions in the vicinity of the accident site. The observed conditions near the accident site supported increasing low-level cloud development and scattered rain showers and thunderstorms. A review of weather radar data revealed that, between 1956 and 1958, the helicopter's recorded GPS flight track bordered an area of very light intensity echoes. During the same time period, there was an area of light radar echoes that had developed immediately south of the accident site. The radar images revealed the potential of lower clouds and restricted visibility with light rain. Following the accident, several small areas of moderate-to-strong rain showers developed about 2 miles south of the accident site. These rain showers moved northward at 10 knots with time. No strong outflow winds or severe storm signatures were associated with the observed rain showers. The closest weather observing station was located at the Gillespie County Airport (T82), Fredericksburg, Texas, about 22 miles northwest of the accident site. At 1955, the automated surface observing system reported: wind 140 degrees magnetic at 5 knots, visibility 10 miles, scattered clouds at 1,900 feet above ground level, temperature 23 degrees Celsius, dew point 22 degrees Celsius, and an altimeter setting of 30.10 inches of mercury. The United States Naval Observatory reported that the sunset and end of civil twilight at the departure airport was at 1908 and 1932, respectively. At the time of the accident, the moon was more than 15 degrees below the horizon and, as such, did not provide any illumination. Additionally, the accident site was located in a sparsely populated area with minimal illumination from ground light sources. As such, dark nighttime conditions existed at the time of the accident. The owner of the property where the accident occurred reported that it had been overcast a majority of the day with a noticeable lower cloud layer at the time of the accident. Between 1910 and 1915, as he was driving east on Farm-To-Market Road, approximately 2 to 4 miles west of his property and approximately 4 miles north of the accident site, he observed a dark cloud to the south and southeast, which he thought was associated with an area of rain. He did not recall seeing any lightning at that time. After arriving home, about 2030, it began to rain lightly to the point where it was necessary to close his house windows.
