Circumstances:
Brand new, the aircraft was took over by ASA crew to be delivered to Atlanta, Georgia. He was cleared by the São José Tower controller to follow the 010° radial to the SJC VOR, and cross the VOR at 5,000 feet. Some time after takeoff São José Tower instructed the flight to climb to FL280 out of 5,000 feet and intercept the 352 radial of the SJC VOR. The flight crew failed to follow the instructions and continued at an altitude of 5,000 feet. In limited visibility due to low clouds, the airplane struck the slope of a mountain located in the Mantiqueira Mountain Range. The wreckage was found 700 feet below the summit. All five occupants were killed.
Probable cause:
The following findings were reported:
- The pilots did not plan the flight properly, though there was an AIS room with the necessary sources of consultation. Maintaining altitude of 5000 feet for too long a time, subject to the minimum safe altitudes in the are area in the available publications, and the discrepancies found in the flight plan confirm this thesis.
- The pilot did not properly collated the guidelines issued by the tower and remained incompatible altitude with instructions issued by the control.
- There are strong indications that the flight proceeded under instrument flight conditions.
- There was no proper coordination between the ACC BS and TWR SJ regarding the transference and control of the air traffic nor did TWR SJ requested receipt of the messages.

Circumstances:
The Fokker F-27, registration YN-BZF, was engaged on a delivery flight from North Yemen to Nicaragua. For the purpose of extended range two 200 US gal auxiliary ferry fuel tanks had been installed in the cabin of the aircraft. YN-BZF departed on 11 April 1985 from North Yemen (Sanaa) via Saudi Arabia (Jeddah), Egypt (Cairo) to Greece (Athens). The flight proceeded from Greece on 19 April 1985 via Italy (Genoa) to Scotland (Prestwick). On 20 April 1985 the flight proceeded from Prestwick via Stornoway to Reykjavik (Iceland) where it arrived at 15:48 hours. Since the crew had been unable to retrieve fuel from the auxiliary ferry fuel system during the preceding part of the flight, they checked the system during the stay at Reykjavik, and they found it to be in working order. An additional check was done by experienced Icelandic F-27 engineers. In the opinion of the ground engineers the auxiliary fuel system "was not very professionally looking" and they "got the feeling that the crew was not quite certain of how to operate it". They advised the crew on how to operate the fuel system and do a ground run to see if it worked. After having received weather information and ATC clearance, the crew took off at 17:21 hours, heading for Kangerlussuaq-Søndre Strømfjord Airport. At 18:32 the Pilot-in-Command transmitted a message to Iceland radio, whom he asked to extend his thanks to the Icelandic engineers with the message that the auxiliary ferry fuel system was working correctly. This message was transmitted prior to passage of Kulusuk at 19:35 hours. During the flight from Reykjavík, Iceland to Greenland the crew informed the air traffic control that problems had arisen with retrieving fuel from the auxiliary ferry fuel system. At 19:50, approximately 50 NM west of Kulusuk, the crew radioed to the radar station BIG GUN about fuel problems, as it had been discovered that the auxiliary ferry fuel system did not function after all. Thus encountering a reduction of fuel reserves by approximately 400 US gal together with a ground speed of only 180 knots the crew decided to return for landing at Kulusuk Airport. However, due to deteriorating weather conditions the aerodrome could not be located. The flight diverted hereafter westbound for an emergency landing at a radar station, "SOB STORY", on the icecap. During descent the aircraft collided with the icecap.
Probable cause:
The following findings were reported:
- The crew was properly certified for the flight,
- According to the crew the normal aircraft systems, except for the FDR and the cockpit right front window electrical deicing system, were functioning normally, which was also determined by the on site investigation,
- The auxiliary ferry fuel system was not functioning properly. The cause of this has not been conclusively established,
- The crew did not undertake a satisfactory functional airborne check of the auxiliary ferry fuel system to ensure that it worked prior to the essential appliance of the system for flight, (cause-factor),
- It is the opinion of this department from the evidence available that a deficiency in the procedures applied for operating the auxiliary ferry fuel system may have been a major factor,
- The assistance rendered to the flight of YN-BZF was active and generally professional. However, the AFIS operator erroneously stated the distance from the KK NDB of 3 NM to be 10 NM.,
- Furthermore the bearing from the KK NDB was not stated by the AFIS operator at BGKK on request from the crew of YN-BZF,
- In the opinion of this department the lack of this information does not seem to have had any important bearing on the possibility of locating the aerodrome,
- Weather conditions were a major factor in this accident, at the time of the approach into BGKK, as well as at the accident site, (cause-factor),
- The Search and Rescue operation was anticipated at an early stage and put into effect immediately after the aircraft was considered to have had an accident,
- The conditions offered on the accident site: low visibility approaching darkness, and consequently the inability to evaluate surface conditions, precluded successful rescue in the first attempt.

Circumstances:
The aircraft crashed after starting a go-around or aborted landing at Norman, OK. The aircraft was on a cross-country flight from Dallas to Wichita. There was no radio communication with the aircraft after it was cleared to land. The approach looked ok but on short final the aircraft suddenly turned right, leveled then entered a steep climbing right turn and continue to roll until inverted then pitched nose down until crashing. The pilot in the right seat had reportedly worked late the night before installing what appeared to be an auxiliary fuel system in the cabin. The aircraft had just been sold and the identity and location of the owner was not established. No one claimed the wreckage. Evidence revealed that both propellers were rotating at high rpm at impact. The fire after impact burned most intensely and persistently in the center of the cabin where the remains of what appeared to be an auxiliary fuel system were found. No pre-impact malfunctions or failures were found. Both occupants were killed.
Probable cause:
Occurrence #1: loss of control - in flight
Phase of operation: go-around (VFR)
Findings
1. (c) reason for occurrence undetermined - pilot in command

Circumstances:
The airplane was just coming out from the PZL-Mielec factory in Mielec, Poland. Three crew members and one passenger were in charge to deliver the plane to Novosibirsk via Lvov, Samara and Omsk. The crew departed Omsk at noon on the last leg to Novosibirsk and continued in good weather conditions bound to the east. While approaching Tatarsk, weather conditions deteriorated with clouds down to 150 meters above the ground. The pilot-in-command reduced his altitude in an attempt to maintain visual contact with the ground. At an altitude of 199 meters, the single engine airplane struck with its both right wings a relay antenna (202 meters high) located about 5 km northeast of Tatarsk. Out of control, the aircraft lost height and crashed 280 meters further in a snow covered field, bursting into flames. All four occupants were killed.
Probable cause:
The crew failed to prepare the flight properly and took the decision to continue to fly under VFR mode into low clouds with a below-minima visibility. The people in charge to transmit to the crew weather bulletin failed to ensure that information were accurate. A lack of discipline and wrong in-flight decisions on part of the crew were considered as contributing factors.

Circumstances:
The aircraft had been on sales demonstration flights and was on a delivery flight from Memphis, TN to Dallas, TX. The plane was observed departing at 1550 CDT in a max performance climb. Radar info from mode C of the transponder returns indicated that the aircraft climbed from 1,000 to 16,000 feet in 7 min and 14 seconds. Level flight was indicated at 16,300 ft from 1558:16 to 1601:17 CDT. The last alt return was from 16,000 ft at 2201:07. Two more returns were received at 2201:49 and 2202:08, but with no altitude readout. At about that time, the aircraft was observed spiraling down, counterclockwise, with a portion of the left wing missing. The wing tip (outer wing panel outboard from about wing station 190), left aileron and left engine tail cone panel were found about 3 miles from the main wreckage impact point. An examination revealed that the wing panel separation occurred upward from positive overload forces. No evidence was found of fatigue or pre-existing failure. Light to moderate turbulence was reported between 14,000 and 18,000 ft msl. The pilot, sole on board, was killed.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: unknown
Findings
1. Weather condition - turbulence
2. (c) wing, spar - overload
