N992AA

HISTORY OF FLIGHT

On October 15, 2008, at 2358 central daylight time, a Bell 222 helicopter, N992AA, operated by Air Angels Inc., and piloted by a commercial pilot, was destroyed when it impacted a radio station tower and the ground in Aurora, Illinois. The tower stood 734 feet above ground level. A post crash fire ensued. The emergency medical services (EMS) transport flight was conducted under 14 Code of Federal Regulations Part 135, and was en route from the Valley West Hospital Heliport (0LL7), Sandwich, Illinois, to the Children’s Memorial Hospital Heliport (40IS), Chicago, Illinois, when the accident occurred. Night visual meteorological conditions prevailed in the area of the accident site. All four occupants, including the pilot, a flight paramedic, a flight nurse, and the 14 month old patient, were fatally injured. The flight originated about 10 minutes prior to the accident.

Reach dispatch (Air Angels flights were dispatched by Reach Air Medical Services in Santa Rosa, California) was notified of the need for EMS transport at 2112 and opened a case record at that time. At 2113, the flight was accepted by Air Angels; however, the flight did not depart the Air Angels base in Bolingbrook, Illinois until 2254. The flight had been delayed until a receiving hospital could be identified. At 2311, N992AA arrived at 0LL7. At 2338, the pilot made a flight following call to Reach dispatch as required in Reach/Air Angels protocol. The flight following call included the helicopter's takeoff weight of 7,635 pounds, the helicopter's center of gravity of 251.7 inches, center of gravity range of 247.65 to 256.0 inches, the planned initial heading of 080 degrees, distance of 38 miles, estimated time en route of 18 minutes, 4 people on board, 1.5 hours of fuel on board, and Children's Memorial Hospital as the destination. The flight following call was made prior to takeoff from 0LL7.

At 2355, the pilot checked in with the DuPage Airport (DPA) air traffic control tower (ATCT) and reported his position as "over Aurora," and that the helicopter was at 1,400 feet above mean sea level (msl). Radar data showed that at the time of the radio call to DPA ATCT, the helicopter was about 12 nautical miles (nm) northeast of the departure heliport. Radar data showed that the helicopter continued on a 072-degree magnetic course. The radar data showed the helicopter on a steady course at a constant altitude of 1,300 feet MSL. The radar track ended at 2358:25 and the location of the last radar return coincided with the location of a radio station antenna tower.

PERSONNEL INFORMATION

The pilot, age 69, held a commercial pilot certificate with rotorcraft-helicopter and instrument helicopter ratings. The certificate also listed private pilot privileges for single-engine land airplanes. The pilot's most recent second class medical certificate was issued in January 2008 and stated that the pilot must wear corrective lenses for near and distant vision.

The pilot was hired by Air Angels in July 2006. A review of the pilot's Air Angels training records indicated that he had accumulated 3,564.7 flight hours total time, including 3,182.7 hours in helicopters and 382 hours in fixed wing aircraft. While employed by Air Angels he had accumulated 282.7 hours in the Bell 222, including approximately 50 hours and 23 hours in the preceding 90 and 30 days respectively. During the month of October the pilot had flown 5.7 hours at night and made 20 night landings in Bell 222 helicopters.

Training records showed that the pilot completed new hire and initial training in July 2006 and his most recent recurrent training was accomplished in August 2008. The pilot's most recent annual line check (FAR Part 135.299) was completed on September 25, 2008.

The pilot resided in Carmel, Indiana, approximately 200 miles southeast of the Air Angels base of operations. Due to this, the pilot would not commute to his home during his duty week and would stay in a bunk room located at the Air Angels facility. On the night of the accident, the pilot was one day into his second week of night shift work. The pilot did not fly on the night before the accident and his most recent flight was on October 13, 2008, with 54 minutes of flight time. A review of the pilot's activities during the 72 hours prior to the accident revealed that he maintained his normal routine and stayed in the bunk room at Air Angels during the day. According to other employees at Air Angels, the pilot appeared well rested and his demeanor seemed normal when he reported for his shift on the accident date.

The Air Angels Director of Flight Operations (DFO) reported that the accident pilot was a very experienced helicopter pilot having flown helicopters during the Vietnam War. The DFO reported that the pilot looked forward to flying each day, was conscientious, and flew landing approaches in a slow meticulous manner. The DFO reported that during the pilot's most recent line check, they received a call for a patient transport and the pilot performed the flight in accordance with the company’s general operating manual. He observed that the pilot did use the helicopter's autopilot function during the en route phase of the flight.

AIRCRAFT INFORMATION

The helicopter was a Bell 222, serial number 47062. It was configured for medical transport of a single patient on a gurney. Air Angels acquired the helicopter in February 1999. The crew consisted of a single pilot, flight nurse, and paramedic. A review of the helicopter's maintenance records revealed that it had 5,302.6 hours total time as of October 14, 2008. The helicopter had two Honeywell (Lycoming) LTS-101-650C engines. The number 1 engine had 5,694.0 hours total time, and the number 2 engine had 3,717.1 hours total time. The most recent phase inspection was performed on September 24, 2008, at 5,270.9 hours total airframe time.

During the flight-following radio call to Reach Dispatch, the pilot reported the weight of the helicopter as 7,635 pounds, the center of gravity (CG) at 251.7 inches and a CG range of 247.65 to 256.0 inches. The Bell 222 Flight Manual, limitations section listed the maximum gross weight for takeoff and landing as 7,850 pounds. Referring to the Bell 222 Flight Manual gross weight center of gravity chart, the CG that the pilot reported was within the normal operating limits as defined by that chart.

The helicopter was equipped with a Garmin GNS 430, which has a combined GPS, navigation, and communications radio that was mounted into the instrument panel. The maintenance records included a FAA form 337 (Major Repair and Alteration) that documented the GNS 430 installation on April 8, 1999. According to the entry, a placard reading "GPS not approved for IFR operation" had been placed on the instrument panel. The GNS 430 software was updated on January 9, 2008. The DFO and Director of Maintenance (DM) stated that the GNS 430 was configured with the Jeppesen aviation database, last updated on June 1, 2008. Although the GNS 430 could display terrain and obstacles, the software for that function had never been installed. The DFO stated that the GNS 430 was their primary source of navigation information.

The helicopter was equipped with four communication radios, which were normally set to the following: local air traffic control (ATC) frequency, dispatch, and 123.025 (helicopter air-to-air common). The medical crewmembers had a Technisonic radio in the cabin that they would use to communicate with the hospital.
