Circumstances:
The accident flight was a scheduled domestic flight from Copenhagen Airport, Kastrup (EKCH) to Aalborg Airport (EKYT). The flight was uneventful until the landing gear was selected down during the approach to EKYT runway 26R. The nose landing gear and the left main landing gear (MLG) indicated down and locked. The right MLG indicated “in transit” (not down and locked). The Aalborg Tower was informed about the problem with the right MLG indication. A go-around was initiated at 1100 feet MSL with a climb towards 2000 ft. The flight crew consulted the Quick Reference Handbook (QRH). An alternate landing gear procedure was initiated. The right MLG indication remained in “transit”. A mayday call was made to Aalborg Tower and they were informed about the unsafe landing gear. The flight crew reset the alternate gear extension system and subsequently they tried to make a normal gear up selection. The nose landing gear and the left MLG retracted normally, however the right main landing gear indication remained in “transit”. A second attempt to use the alternate landing gear extension procedure was performed without any changes to the right MLG indication. The aircraft entered a holding pattern in order to reduce the amount of fuel and at the same time to brief the passengers about the situation and to prepare the passengers for an emergency landing. Passengers seated at rows 6, 7 and 8 seats D and F were reseated away from the right propeller area. During the approach the flaps were selected to 10° and the landing gear horn started. The warning horn continued throughout the remaining flight. During the emergency landing the left MLG touched down on the runway first, followed by the right MLG. Shortly after the right MLG contacted the runway the right MLG collapsed. The aircraft departed the runway to the right and came to rest on a heading of 340° at 1357:26 hrs.
Probable cause:
There were five factors’ leading to the accident:
1. There were no specified inspection tasks for inspection of the MLG retraction/extension actuator and rod end either in the MRB’s report or in the Maintenance Requirement Manual in so far as “L”, “A” and “C” checks.
2. The right and left MLG retraction/extension actuator piston and rod end were made of noble martensitic stainless steel and the less noble 4340 steel material, respectively.
3. Severe corrosion in the threaded connection between the right MLG actuator rod and rod end.
4. Separation of the right MLG retraction/extension actuator from the actuator piston rod end.
5. The right MLG stabilizer joint lugs failed.

Circumstances:
On September 8, 1989, LN-PAA was on a charter flight to Hamburg. The flight was due to depart at 1500 hrs. The call sign was Partnair (PAR) 394. The departure was delayed by almost an hour due to the Civil Aviation Administration, Norway (CAA/N) and the catering company having suspended PAS' credit. Once the financial problem was settled the crew was given permission to depart. During the period September 6-8, 1989 LN-PAA experienced some technical problems with the left AC power system. The AC generator was replaced, but the malfunction in the system remained. On the flight to Hamburg it was decided to use the APU generator as the electrical power source for the left AC system. LN-PAA took off at 1559:50 hrs. The flight proceeded normally to the planned cruise level, which was FL220. At 1604 hrs PAR 394 was cleared direct to AAL VOR/DME (Aalborg). When the aircraft climbed through FL 180 at 1616 hrs, the crew was informed by Oslo ACC about strong westerly winds at altitude. The air traffic controller suggested a 100 heading change to the right. At 1622 hrs PAR 394 was informed that the radar service from Oslo Ace terminated and that the flight would enter Danish-controlled air space in 2 minutes. PAR 394 was then requested to contact Copenhagen ACC. According to the aircraft's Flight Data Recorder (FOR), LNPAA reached its cruising level at 1623 hrs. Half a minute later the crew established contact with Copenhagen ACC and informed them that PAR 394 was maintaining FL220, whereupon Copenhagen ACC confirmed that they had radar contact. This was the last radio contact anyone had with PAR 394. The next control point was AAL VOR/DME. Apparently, the flight proceeded normally until the air traffic controller at Copenhagen ACC observed that the radar signals from PAR 394 showed an unexpected right turn and then disappeared from the radar scope. At 1640 hrs the air traffic controller tried to contact PAR 394, but there was no reply. He tried again several times. At 1642 hrs the ATS in both Denmark and Norway initiated an investigation to locate the aircraft. At 1659 hrs it was decided to inform the rescue authorities in Norway and Denmark. It turned out that a serious accident had occurred. None of the 55 persons on board survived.
Probable cause:
The accident was caused by loss of control due to the destruction of primary control surfaces in the tail section, which, in turn, was caused by aeroelastic oscillations initiated by abnormal clearances in the vertical stabiliser attachments to the fuselage structure. The condition of the attachments was a result of excessive wear in pins and sleeves used in this structural joint. The pins and sleeves were of an inferior quality and did not satisfy specified values for hardness and tensile strength. They had also been installed and inspected using sub-standard maintenance procedures. Undamped oscillations in the elevator contributed to the structural failure of the empennage.
