IAI 1124 Westwind

On 18 November 2009, the flight crew of an Israel Aircraft Industries Westwind 1124A aircraft, registered VH-NGA, was attempting a night approach and landing at Norfolk Island on an aeromedical flight from Apia, Samoa. On board were the pilot in command and copilot, and a doctor, nurse, patient and one passenger. On arrival, weather conditions prevented the crew from seeing the runway or its visual aids and therefore from landing. The pilot in command elected to ditch the aircraft in the sea before the aircraft’s fuel was exhausted. The aircraft broke in two after ditching. All the occupants escaped from the aircraft and were rescued by boat.

At 0444Z On May 24 2006, Miami Centre (George Town Sector) informed Nassau ATC That Lifeguard Flight N475AT, a Westwind Jet (WW-1124), en-route from San Juan, Puerto Rico to Norfolk, Virginia reported that it had developed generator problems and the aircraft was looking to land at the nearest airport to its position. Miami Air Traffic Center vectored the aircraft to Exuma International Airport at Great Exuma, Bahamas, as that was the nearest airport. Attempts were made by Nassau ATC to contact the authorities at Exuma International Airport to have the runway lights turned on. At 0454Z, Miami ATC reported loss of contact with the aircraft; therefore, N475AT proceeded with an emergency landing, before Miami ATC could give further instructions. The uncontrolled aircraft came to rest approximately 800 feet beyond the end of runway 30 and approximately 300 feet right of the extended centre line of the runway. The aircraft landing gears were sheered off when the aircraft exited the runway, hence traveling into the clearing and then eventually into the bushes on the right side of the runway. The right wing of the aircraft collided with a mound of dirt, causing it to spin uncontrollably, resulting in it coming to rest on an easterly heading at an approximate 30 degree incline. The occupants were evacuated from the wreckage and received minor injuries while making their way thru the thick brush and shrubbery while being led to safety. All Crew members were ATP rated and both proficiency checks found to be were valid and current neither of the pilots was available for an interview at the time of the field investigation at Exuma International Airport.

The aircraft departed Toluca Airport at 1516LT on a flight to Colima, carrying five members of the Colima Government and two pilots. Fifteen minutes into the flight, while cruising at an altitude of 16,000 feet, the crew informed ATC about control problems and was cleared to divert to Morelia Airport via radial 160. Shortly later, the aircraft entered an uncontrolled descent and crashed in a wooded and mountainous terrain located near El Devanador. The aircraft was totally destroyed and all seven occupants were killed.

On July 2, 2004, at 1338 eastern standard time, a U.S. registered Westwind model 1124 corporate jet, N280AT, operated by Air Trek, Inc., as a Part 135 commercial air ambulance flight, impacted terrain and crashed into a building after departing from the Tocumen International Airport (MPTY), Tocumen, Panama. The airplane was destroyed by impact forces and post-crash fire. All six occupants on the airplane were fatally injured. A seventh person was also fatally injured on the ground. Visual meteorological conditions prevailed, and an instrument flight rules (IFR) flight plan was filed. The flight originated from Quito, Ecuador, and stopped in Tocumen for fuel. The flight was destined for Milan, Italy, via another fuel and crew-change stop at the Dulles International Airport, near Washington, DC. According to the operator, the airplane was flown with the two pilots and two flight nurses from Punta Gorda, Florida, to Guayaquil, Ecuador, on July 1, 2004. The airplane was refueled with 450 gallons of Jet A upon arrival, and remained overnight. On July 2, 2004, the airplane was fueled with an additional 150 gallons of Jet A, and subsequently departed for Quito, Ecuador. Upon arriving in Quito, two passengers were boarded, and the flight departed for Panama, where it would be refueled. The airplane was not fueled during the stop in Quito. According to the Panama Autoridad Aeronautica Civil, the flight landed in Panama uneventfully, and proceeded to the north ramp at the main terminal. The flightcrew requested from ground service personnel that the airplane be refueled with 600 gallons of Jet A. The flightcrew specifically requested that 500 gallons of fuel be added utilizing the pressure point fueling station, and 100 gallons be added to the auxiliary tank, utilizing a gravity filler port. After refueling, the airplane was started and taxied to runway 03L. An air traffic controller observed the airplane as it began to takeoff. He recalled that, "It pitched up vertically, the nose then lowered, and the wings rocked side to side. The airplane then veered to the right and descended out of view." A witness, who was located north of the accident site, observed the airplane veering to the right, before descending from his view. The airplane impacted the ground on taxiway Hotel, north of taxiway Bravo, and a fire ensued. The right wing and right engine separated from the fuselage and fragmented into multiple pieces. The vertical stabilizer impacted the ground, and separated from the fuselage. The main fuselage, left wing, and left engine continued across a grass field, where it struck an airport worker, and impacted a concrete wall. The airplane continued through the wall, and came to rest inverted inside a building. Airport crash fire and rescue responded to the accident, and contained the post crash fire within 3 minutes. The wreckage path was oriented on a heading of about 80 degrees. Ground scars on the taxiway were consistent with the right wing tip tank impacting the taxiway surface with the airplane in a nose high attitude, banked 90 degrees to the horizon. The scars continued forward, with the airplane rolling onto its back, collapsing the vertical stabilizer. About 35 feet beyond the vertical stabilizer impact point, scars were observed from the left tip tank. Debris from the cockpit and forward cabin area was observed in the grass area along the wreckage path. Airport personnel tested the fuel truck used to refuel the airplane for contamination after the accident. No abnormalities were noted. The cockpit voice recorder (CVR) was forwarded to the National Transportation Safety Board, Washington, D.C. for further review. The left and right engines, the horizontal stabilizer trim actuator, and the airplane's annunciator warning panel, were also retained for further examination.

After passing the initial approach fix, during an instrument approach to the destination airport, radar and radio contact were lost with the business jet. One witness reported hearing "distressed engine noises overhead," and looked up and saw what appeared to be a small private jet flying overhead. The engine seemed to be "cutting in and out." The witness further reported observing the airplane in a left descending turn until his view was blocked by a ridge. The witness then heard an explosion and saw a big cloud of smoke rising over the ridge. A second witness heard a loud noise and looked up and saw a small white airplane with two engines. The witness stated that the airplane started to turn left with the nose of the airplane slightly pointing toward the ground. The airplane appeared to be trying to land on a road. A third witness heard the roar of the airplane's engines, and looked toward the noise and observed the airplane in a vertical descent (nose dive) impact the ground. The witness "heard the engines all the way to the ground." Examination of the airframe and engines did not disclose any structural or mechanical anomalies that would have prevented normal operation. The National Weather Service had issued a SIGMET for severe turbulence and mountain wave activity. Satellite images depicted bands of altocumulus undulates and/or rotor clouds over the accident site.

During the activation of the crew oxygen system a fire erupted which consumed the entire pressure vessel. Representatives from the National Aeronautics and Space Administration's (NASA) Johnson Space Center (JSC), White Sands Testing Facility (WSTF), Las Cruces, New Mexico, examined the retained oxygen system components. Examination of these components revealed that the fire's initiation location was the first stage pressure reducer located in the oxygen regulator assembly.
