If you continue the open source article it says "While NDB approaches are essentially obsolete in the United States, they are still used widely in other parts of the world. Because of their infrequent use in the United States, many American pilots are not fully proficient in performing them (a NASA survey showed that 60% of American transport-rated pilots had not flown an NDB approach in the last year).
[2] The investigation board determined that the approach used was not approved for
Department of Defense aircraft, and should not have been used by the aircraft crew.
[6] The board determined that the particular NDB approach used required two operating
ADFs, the instrument used to fly such an approach, on board the aircraft, but this aircraft only had one ADF installed. To successfully fly the approach, one ADF was required to track the outbound course of 119° from the Koločep NDB (KLP), while another ADF was required to observe when the aircraft had flown beyond the
Cavtat NDB (CV), which marked the
missed approach point.
[7] Further, the board noted that the approach was rushed. The aircraft passed the final approach fix at 80 knots (150 km/h) above the proper approach speed and had not received the proper clearance from the control tower to initiate the approach.

They didn't goof up an NDB approach, they didn't have the proper equipment to fly a procedure in the weather, in the mountains, so they improvised based off an illegal approach plate, had an unstable approach, didn't initiate a missed approach even though they were past the MAP, and smacked into a mountain. That's not the NDB's fault, thats just horrible ADM.
