On July 19, 1967, a Boeing 727 took off from Asheville Municipal Airport in North Carolina on Piedmont Airlines Flight 22 to Roanoke Municipal Airport in Virginia . A short time later it collided with an approaching Cessna 310 . Both planes crashed, killing all 82 occupants. The main reason for the accident was that the Cessna deviated from its approved course, due to failure by air traffic control.

course
In its investigation report published in September 1968, the US Accident Investigation Authority NTSB came to the following conclusions:
The Cessna 310 N3121S had taken off from Charlotte Airport, North Carolina at around 11:30 a.m. for its destination Asheville Municipal Airport , some 150 km to the west .
Flight 22 took off at 11:58 am from Runway 16 at Asheville Regional Airport for an instrument flight to Roanoke Municipal Airport in Virginia, with instructions from the air traffic controller to maintain the runway course until you pass 5000 ft (1524 m ) and then continue to 21,000 ft to rise. At 11:51 am, the pilots of the Cessna received the information to prepare for an ILS approach , which they did.
While the Boeing 727 was still taxiing, the Cessna confirmed that it had reached the rotating beacon (VOR) Asheville and was cleared to descend to 6000 ft (1830 m ). At 11:59:44, the air traffic controller cleared flight 22 for a further climb directly to VOR Asheville. Only after they had overflighted the VOR did he give the Cessna pilots clearance for an unexpected ADF- 2 approach to runway 16; this was a completely different procedure than the planned ILS approach.
The Boeing 727 was making a left turn when the collision between the Boeing 727 and the Cessna 310 occurred at an altitude of 6132 ft (1870 m ) at 12:01:18 p.m. This was not on the course prescribed for the ADF-2 approach.
The following were named as possible causes in the accident report: Confusion or misinterpretation on the part of the Cessna pilots, due to the very short-term change to a completely different approach procedure, or deliberate deviation from the last clearance.
In summary, the main cause was the deviation of the Cessna from its approved course, also due to insufficient flight preparation. The contributing cause was the failure of air traffic control to issue correct approach clearance in good time.
