Circumstances:
The MD-82 arrived at Panama City-Tocumen after a flight from Medellín-José María Córdova Airport (MDE). The plane was then prepared to carry out a flight to the Caribbean island of Martinique. Flight WCW 708 departed Panama City at about 06:00 UTC and climbed to its cruising altitude of FL310. This altitude was reached at about 06:25 UTC. Sixteen minutes later the airplane began a normal climb to FL330. At 06:49 the speed began to steadily decrease from Mach 0.76. The horizontal stabilizer moved from about 2 units nose up to about 4 units nose up during this deceleration. At 06:51 UTC the crew reported at FL330 over the SIDOS waypoint, over the Colombian/Venezuelan border, and requested a direct course to the ONGAL waypoint. The controller instructed the crew to continue on the present heading and to await further clearance direct to ONGAL. The flight crew meanwhile discussed weather concerns that included possible icing conditions and the possible need to turn on engine and airfoil anti-ice. At 06:57 UTC the flight crew requested permission to descend to FL310, which was approved. The autopilot was disconnected and the airplane started to descend. As the airplane descended past about FL315, the airspeed continued to decrease and the engine EPR decreased to about flight idle. Two minutes later a further descent to FL290 was requested, but the controller at Maiquetía did not understand that this was a request from flight 708 and asked who was calling. Flight 708 responded and immediately requested descent to FL240. The controller inquired about the state of the aircraft, to which they responded that both engines had flamed out. The controller then cleared the flight to descent at pilot's discretion. In the meantime, the altitude alert warning had activated, followed by the stick shaker and the aural stall warning alert. The airspeed had reached a minimum of about 150 indicated air speed (IAS) knots at about FL250. The crew reported descending through FL140 and reported that they were not able to control the airplane. The aircraft descended at 7,000 ft/min, and finally crashed in a swampy area. The aircraft disintegrated on impact and all 160 occupants were killed. Debris were found on an area of 205 metres long and 110 metres wide. The entire descent from FL330 had taken approximately 3 minutes and 30 seconds.
Probable cause:
Given the aerodynamic and performance conditions, the aircraft was taken to a critical state, which led to a loss of lift. Consequently, the cockpit resource management (CRM) and decision-making during the development of emergency were misguided. This was caused by the following:
a) Awareness of environment (or situational awareness) insufficient or improper that allowed the cockpit crew, not being full and timely aware of what was happening regarding the performance and behavior of the aircraft.
b) Lack of effective communication between the cockpit crew that limited, within the decision making process, the possibility to timely choose appropriate alternatives and options and to set respective priorities in the actions taken at the time when it was established that there was a critical or emergency situation (stall condition at high altitude).
It is found that the cause of the accident is determined by the absence of appropriate action to correct the stall of the aircraft, and also in the emergency up to the impact with the ground, at an inappropriate hierarchy of priorities in implementing the procedures. Subsequently, the operations were conducted outside of the limits and parameters set by the manufacturer's manual performance, together with an inadequate flight planning by failing to consider meteorological aspects, in addition a misinterpretation and late of the energy state of the aircraft by the flight crew. Therefore, the evidence shows the classification of "Human Factor" as a cause of this accident.

Circumstances:
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.

Circumstances:
Following an uneventful flight from Miami-Intl Airport, the crew started the descent to Panama City-Tocumen Airport. Actual weather conditions were poor with low clouds, rain falls and turbulences. On final, the aircraft was not properly aligned on runway 03R but the crew continued the approach. Too high on the glide, the aircraft landed 750 metres past the runway threshold and after a course of about 2,500 feet, it veered to the left and departed the runway. While contacting taxiway Hotel, the nose gear collapsed and the aircraft came to rest 450 metres further. All 92 occupants evacuated safely and the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the crew who failed to initiate a go-around procedure while the aircraft was not properly aligned on runway 03R during an ILS approach. Poor crew coordination was a contributing factor.

Circumstances:
On the leg from Panama City to Medellín, the crew was approaching the Abejorral NDB at an altitude of 16,000 feet and was cleared to descend to FL120. Few minutes later, while descending to the altitude of 12,300 feet in poor weather conditions, the three engine aircraft struck the slope of Mt Páramo Frontino located about 85 km northwest of Medellín-José María Córdova Airport. The aircraft disintegrated on impact and all 132 occupants were killed. At the time of the accident, the visibility was poor due to clouds, mist and rain.
Probable cause:
It was determined that the accident was the consequence of a controlled flight into terrain after the crew mistakenly initiated the descent prematurely, causing the aircraft to descend below the minimum prescribed altitude. It was established that the crew reported to be over the Abejorral NDB while in fact, the aircraft did not reach already this beacon. Thunderstorm activity probably influenced some instruments and the RNG VOR was out of service since few month following a terrorist attack.

Circumstances:
The airplane departed Panama City-Tocumen Airport runway 21L at 2036LT bound for Cali, Colombia. While cruising at FL250, the crew was informed about poor weather conditions 30-50 miles ahead. Shortly later, there was an intermittent failure of the main attitude indicator due to a short circuit. This was not noticed by the flight crew, who attempted to adjust the aircraft attitude based on the false information from the attitude indicator. They lost control of the aircraft which entered a steep descent and started to disintegrate at FL100, and impacting the ground 80° nose down. The wreckage was found in the jungle about 13 km southwest of Tucití. All 47 occupants were killed.
Probable cause:
The following findings were reported:
- Loss of control of the aircraft because the flight crew followed false information from an attitude indicator that operated intermittently.
- Lack of visible horizon during cruise flight due to night and approaching bad weather.
- Insufficient cross-checking between the primary and emergency (standby) attitude indicators to identify intermittent attitude errors and to select a reliable source of (correct) attitude information.
- Non-standard cabin configurations between aircraft in the fleet of the company, which required the crew to determine how to set the switches based on the aircraft was being operated at the time.
- Incomplete ground crew training simulator, as it did not present 'differences between aircraft' and 'crew resource management' in sufficient detail to give the crew knowledge to overcome intermittent attitude indicator errors and to maintain control of the aircraft.
