MIA02FA161

The pilot stated that during the takeoff he became distracted by a large section of torn awning which was flapping in the wind due to the rotor's downwash, and the helicopter's main rotors impacted the top corner of the building on the right. The helicopter stopped climbing and began to settle, and the pilot said he lowered the collective, and navigated between the building and the parking garage, to the street below, applying full collective pitch to cushion the landing on the street. He then performed the emergency shutdown procedures, and he and his crew egressed from the helicopter. The helicopter incurred damage to the main rotors and fuselage. The copilot stated that he was seated on the left side clearing for obstructions and heard a bump on the right side, followed by repetitive bumps, and saw chunks of helicopter pieces fly by, as the helicopter started to settle. The copilot said that the helistop is largely surrounded by buildings and every takeoff using the accident helicopter from the Miami Children's hospital was a maximum performance takeoff, with very little margin for error. He stated that the departure required the helicopter to be flown from the helipad over an awning covering a walkway and in between buildings on both sides down a street with very little clearance from the buildings, while executing a maximum performance takeoff to climb to gain altitude as quickly as possible. He stated that the operation at the Miami Children's Hospital had been a new contract, and that his management had told the flight crews that they knew it was "tight in there, but to deal with it since they needed the work." The copilot stated that he had not received any site specific training to operate at the Miami Children's hospital helipad since his employment by the operator through the date of the accident. He said that flight related training was not conducted at the Miami Children's helistop due to the hospital's desire to reduce the noise in the residential neighborhood. On September 5, 2002, a Florida Department of Transportation (FL DOT) official and a FAA inspector examined the Miami Children's Hospital helistop, and noted that a significant amount of construction related changes had taken place since the last helistop inspection. FL DOT official stated that the construction included an elevated helipad, and that based on the new construction she requested that Miami Children's Hospital conduct a survey to determine whether the required clearance requirements to retain the helistop license had changed since issuance of the license. The Vice President/Chief Nursing Officer of the Miami Children's Hospital stated that at FL DOT's request, a survey of the helistop was performed, and upon review of the survey by the management of the Miami Children's Hospital, management's impression was that the clearance requirements for the helistop had not been met due to the new construction/expansion, and helicopter operations at the hospital was suspended until the elevated helipad was completed. A review of FAA records showed that prior to the accident, no reviews/oversight of flight operations at the Miami Children's Hospital's helistop had been conducted by the FAA. An FAA inspector stated that the operator had recently obtained the contract to operate the accident helicopter at the Miami Children's Hospital, and that prior to the accident no evaluation/oversight of the Title 14 CFR part 135 operation had not yet been performed due to it having been a new operation.

History of flight

On August 31, 2002, about 1219 eastern daylight time, a Sikorsky, S-76 A+, N15460, registered to Variety Children's Hospital, also known as Miami Children's Hospital, and operated by Air Methods Inc., as a Title 14 CFR Part 91 aeromedical flight, collided with a corner of a multi-story parking garage at Miami Children's Hospital, Miami, Florida, during takeoff/initial climb. Visual meteorological conditions prevailed, and a company visual flight rules flight plan was filed. The airline transport-rated pilot and two medical crewmembers employed by the hospital, received minor injuries, and the commercial-rated copilot received a serious injury. The helicopter incurred substantial damage. The flight was originating at the time of the accident.

The pilot stated that after receiving a request for aeromedical transport, he and his crew were proceeding to Marathon, Florida, to embark a patient and return to the Miami Children's Hospital. The pilot further stated that he was the pilot flying, and the copilot was monitoring the takeoff and clearing for obstacles on the left side. He said that prior to the accident, all events had been normal. The departure path from the helipad is to the east, over an awning which covers a walkway , and which also crosses a street, between an office building, and a multi-story parking garage. The pilot stated that since a raised helipad was presently under construction, exit from the current helipad comprised of the path he had followed, over the awning, while climbing over the street between the building and the parking garage. According to the pilot, as the helicopter was about to pass over the awning he became distracted by a large section of torn awning which was flapping in the wind due to the rotor's downwash. He said he was concerned that the awning not be drawn into the tail rotor as the helicopter passed over the awning, and while he was momentarily distracted, the helicopter's main rotors impacted the top corner of the parking garage on the right side. The helicopter stopped climbing and began to settle, and the pilot said he lowered the collective, and navigated between the building and the parking garage, to the street below, applying full collective pitch to cushion his forced landing on the street. He then performed the emergency shutdown procedures, and he and his crew egressed from the helicopter. The helicopter incurred damage to its main rotors and fuselage. The pilot stated that prior to the accident, there had been no mechanical failure or malfunction to the helicopter or any of its systems.

The copilot stated that the pilot was flying the helicopter, and he was seated on the left side, clearing for obstructions. He said that he heard the sound of, and felt a bump on the right side, and then he heard and felt repetitive bumping, and saw chunks of helicopter pieces fly by, as the helicopter started to settle. He said the pilot steered the helicopter between the buildings, and after the helicopter impacted the ground he heard the pilot say don't get out until everything had stopped. After everything had stopped the copilot said he exited the helicopter and while doing so, tripped on the sidewalk. The copilot also stated that from the helipad's position, the helistop consists of an area largely surrounded by buildings which made every takeoff using the accident helicopter from the Miami Children's hospital, always a maximum performance takeoff, and which left little margin for error. He stated that the helicopter contained all kinds of medical equipment, and with the medical crewmembers on board, it is normally heavy. According to the copilot, the departure required the helicopter to be flown from the helipad over the awning covering a walkway, and after flying over the awning, the helicopter must be flown toward and between the building and parking garage on both sides down a street, while attempting to climb. He added that there is very little clearance from the walls of the building and the parking garage on both sides, while executing a maximum performance takeoff to climb to gain altitude as quickly as possible. The copilot said that the operation at the Miami Children's Hospital had been a new contract, and added that he remembered Air Method's management telling him and the pilot that they knew it was "tight in there, but to deal with it since they needed the work." The copilot stated that he never received any site specific training to operate at the Miami Children's hospital helistop from the date of his initial employment, through the date of the accident. He added that that flight training was not conducted at the Miami Children's helistop due to the hospital's desire to restrict noise in the residential neighborhood and maintain good community relations.

Wreckage and impact information

The helicopter's main rotors impacted the top corner of the parking garage on the right while departing to the east. As the rotors successively hit the parking garage, pieces of the main rotor were thrown, and impacted both the office building, and parking garage that lined the street over which the departure was being flown. The helicopter settled, and came to rest on the lawn adjoining the south edge of the street, in between the bui
