Circumstances:
While on the return leg of a non-scheduled 14 CFR Part 135 VFR cross-country flight, the airplane collided with mountainous terrain at approximately 9,100 feet above mean sea level. Prior to the accident, the pilot informed air traffic control that he was VFR and level at 8,500 feet MSL. Dark night conditions prevailed at the time of the accident. The aircraft crashed on the south-facing slope of the 9,100-foot mountain near the last recorded radar position. Wreckage and impact signatures at the crash site were indicative of high energy and shallow impact with the terrain. The investigation revealed no evidence of any aircraft mechanical problems.
Probable cause:
The pilot's failure to maintain adequate terrain clearance during cruise, which resulted in the in-flight collision with mountainous terrain. Dark night conditions and mountainous terrain were contributing factors.

Circumstances:
At 0906 Eastern Standard Time on 28 July 2004, a Piper Aircraft Corporation PA31T Cheyenne aircraft, registered VH-TNP, with one pilot and five passengers, departed Bankstown, New South Wales on a private, instrument flight rules (IFR) flight to Benalla, Victoria. Instrument meteorological conditions at the destination necessitated an instrument approach and the pilot reported commencing a Global Positioning System (GPS) non-precision approach (NPA) to Benalla. When the pilot had not reported landing at Benalla as expected, a search for the aircraft was commenced. Late that afternoon the crew of a search helicopter located the burning wreckage on the eastern slope of a tree covered ridge, approximately 34 km southeast of Benalla. All occupants were fatally injured and the aircraft was destroyed by impact forces and a post-impact fire.
Probable cause:
Significant factors:
1. The pilot was not aware that the aircraft had diverged from the intended track.
2. The route flown did not pass over any ground-based navigation aids.
3. The sector controller did not advise the pilot of the divergence from the cleared track.
4. The sector controller twice cancelled the route adherence monitoring alerts without confirming the pilot’s tracking intentions.
5. Cloud precluded the pilot from detecting, by external visual cues, that the aircraft was not flying the intended track.
6. The pilot commenced the approach at an incorrect location.
7. The aircraft’s radio altimeter did not provide the pilot with an adequate defence to avoid collision with terrain.
8. The aircraft was not fitted with a terrain awareness warning system (TAWS).

Aircraft flight hours:

Circumstances:
The airplane, which was not operating on a flight plan, was proceeding in clear skies to an airport where the passenger was joining his wife. After crossing a lake near the destination, the airplane flew over rising terrain, along a saddleback, until it struck a stand of old-growth trees that jutted above new-growth trees. During the last 48 seconds of radar coverage, the airplane climbed 600 feet with no erratic course deviations. From the accident location, the airport would have been about 5 nautical miles off the airplane's right wing. The pilot had 32,000 hours of flight experience. The passenger was under investigation for fraud, and attempted to obtain life insurance prior to the flight. The passenger had also loaned money to the pilot, and was receiving "flight services" in lieu of cash payment when the pilot failed to pay back the loan. A .380 caliber pistol magazine was found at the accident site with two rounds of ammunition missing; however, no weapon was located at the site, and no weapon of that caliber was known to be associated with either the pilot or the passenger. Premature ventricular complexes (PVCs) were found on electrocardiograms performed in conjunction with the pilot's airman medical certificate applications in 2002 and 2004. The pilot's autopsy report indicated "severe calcific... coronary disease, with 90 percent narrowing of the left anterior descending coronary artery and 75 percent narrowing of the right coronary artery." Cause of death, for both the pilot and passenger, was listed as "undetermined." The autopsy reports also noted that, "due to the inability to perform a complete autopsy...of either of the two aircraft occupants, it cannot be determined whether either the pilot or the passenger were alive or dead at the time of the crash." Post accident inspection of the airplane disclosed no evidence of any preimpact anomalies.
Probable cause:
Reason for occurrence undetermined.

Circumstances:
An IFR flight plan and slot reservation were filed for the planned flight over mountainous terrain. The flightcrew intended to reposition to an airport about 30 miles southeast of the departure airport, pick up passengers, and then complete a revenue flight to another airport. The airplane departed VFR, and the flightcrew never activated the flight plan. A debris path was located, consistent with straight and level flight, near the peak of a mountain at 3,475 feet msl. Examination of the wreckage did not reveal any pre-impact mechanical malfunctions. Instrument meteorological conditions prevailed near the accident site, about the time of the accident. Further investigation revealed the aircraft operator was involved in two prior weather related accidents, both of which resulted in fatalities. A third accident went unreported, and the weather at the time of that accident was unknown. Over a period of 14 years, the same FAA principal operations inspector was assigned to the operator during all four accidents; however, no actions were ever initiated as a result of any of the accidents.
Probable cause:
The pilot-in-command's improper decision to continue VFR flight into IMC conditions, which resulted in controlled flight into terrain. Factors were the FAA Principle Operations Inspector's inadequate surveillance of the operator, and a low ceiling.

Circumstances:
The twin engine aircraft departed Skopje on an official flight to Mostar, carrying two pilots and seven passengers, among them Boris Trajkovski, President of the Republic of Macedonia. He was flying to Mostar with members of his government to take part to an economic conference. On approach by night and limited visibility due to marginal weather conditions, the aircraft struck the slope of a mountain located near Berkovići, about 32 km southeast of the airport. The aircraft was destroyed by impact forces and a post crash fire and all nine occupants were killed.
Probable cause:
The accident was the consequence of a controlled flight into terrain after the crew initiated the approach prematurely. The following contributing factors were identified:
- Poor approach and landing preparation and planning,
- The crew ignored ATC information about the current meteorological situation at Mostar Airport,
- The crew misinterpreted the Final Approach Fix (FAF) with the Intermediate Approach Fix (IAF), causing the aircraft to start the descent prematurely,
- The crew disengaged the autopilot system during the approach while descending in complex meteorological conditions,
- Poor crew resources management,
- Lack of crew communication,
- The crew failed to comply with SOP's,
- Failure of the pilot-in-command to maintain flight level when the aircraft reached the MDA and failure of the second pilot to give adequate assistance.

Circumstances:
The aircraft departed Rome-Ciampino Airport on an ambulance flight to Cagliari, carrying three pilots, three doctors and a cooler containing a heart for a patient. The descent to Cagliari-Elmas Airport was initiated by night under VFR mode. After the crew was cleared to descend to 2,500 feet, ATC reported runway 32 in use and asked the crew to report on short final. About two minutes later, at an altitude of 3,333 feet, the aircraft struck the slope of Mt Su Baccu Malu located 32 km northeast of Cagliari Airport. The aircraft was totally destroyed by impact forces and all six occupants were killed.
Probable cause:
The accident, classified as CFIT, was caused by the conduct of the flight at a height significantly below the Area Minimum Altitude, insufficient to maintain the separation from the ground during a night visual approach in the absence of adequate visual reference.
possible contributory factors that have been identified:
- The aircraft instrumentation did not include a GPWS or TAWS, whose installation is not required by law;
- The erroneous descent by visual flight references, confusing the Elmas runway lights, given that the crew had no special familiarity with the area of Cagliari, the onset of a perspective illusions phenomena, with specific reference to the so-called "black hole approach";
- The misunderstanding by crew members, of the Cagliari Approach controllers instruction to transfer to Elmas TWR ('CIT 124 continue not below 2500 feet, further descent with Elmas TWR 120.6 bye') which may have created the impression, despite the crew had confirmed that they are able to separate themselves from the obstacles that the descent down was free of obstructions;
- Failure to use published procedures and available instruments in a descent to a closer airport and in an unfamiliar area , under conditions of total darkness;
- The anticipation of the deviation from the airway perhaps caused [the crew] to try to speed up the arrival at destination, which determined overflying areas of higher elevation;
- Read errors of the elevations listed in the maps consulted, facilitated by the non representation of the ground color;
- The extended period of wakefulness without adequate rest, which may have contributed to a reduction in the performance of the crew.
Final Report:
