Pakistan International Airline's Flight 268 Crashes, Killing 167

Pakistan International Airlines Flight 268 was an Airbus A300B4-203, registration AP-BCP, which crashed on approach to Kathmandu's Tribhuvan International Airport on 28 September 1992.

All 167 on board were killed.

Flight 268 departed Karachi at 11:13 AM Pakistan Standard Time for Kathmandu. Upon contacting Nepalese air traffic control, the aircraft was cleared for an approach from the south called the Sierra approach. An aircraft cleared to use this approach was at the time directed to pass over a reporting point called "Romeo" located 41 miles south of the Kathmandu VOR (or at 41 DME) at an altitude of 15,000 feet. The aircraft was to then descend in seven steps to 5,800 feet, passing over a reporting point known as "Sierra" located at 10 DME at an altitude of 9,500 feet, before landing at Kathmandu. This approach allowed aircraft to pass over the Chure Hills directly south of Kathmandu (the crest of which is located just north of the Sierra reporting point) at a safe altitude.

PIA flight268 departed Karachi at 11.13h for a flight to Kathmandu. The en route portion of the flight was uneventful and the aircraft was cleared for a Sierra approach to Kathmandu Runway 02. The crew was instructed to maintain 11500ft and report at 16DME (16mls from the VOR/DME beacon, which is located 0,6nm short of the runway). The Kathmandu approach is very difficult, since the airport is located in an oval-shaped valley surrounded by mountains as high as 9,665ft. Runway elevation is 4313 amsl. The next approach fixes for PIA flight 268 were at 13 DME (at 10500ft), 10DME (at 9500ft) and 8 DME (at 8200ft). A few seconds after reporting 10 DME, the aircraft was descending through 8200ft (the altitude for 8 DME!). The Airbus crashed into a steep cloud-covered hillside at approx.7300ft amsl., at 9,16 DME.
