'''Vietnam Airlines Flight 815''' was a scheduled [[Vietnam Airlines]] flight which crashed on final approach to [[Phnom Penh International Airport|Pochentong International Airport]] in Cambodia on 3 September 1997. The [[Soviet Union|Soviet]]-built [[Tupolev Tu-134|Tupolev Tu-134B-3]] airliner crashed approximately ((convert|800|m|ft yd|abbr=)) short of the Phnom Penh runway, killing 65 of the 66 people on board. As of February 2024, it remains the deadliest accident in Cambodian history.<ref name="asn">((Cite web|last=Ranter|first=Harro|title=ASN Aircraft accident Tupolev Tu-134B-3 VN-A120 Phnom Penh-Pochentong Airport (PNH)|url=https://aviation-safety.net/database/record.php?id=19970903-0|access-date=2019-05-02|website=Aviation Safety Network|publisher=[[Flight Safety Foundation]]))</ref> Upon investigation, the crash was determined to have been the result of [[pilot error|improper actions by the pilot]].

The aircraft was manufactured on 5 October 1984, registration number VN-A120, [[serial number]] 66360.<ref>((cite web|title=REGISTRATION DETAILS FOR VN-A120 (VIETNAM AIRLINES) TUPOLEV TU-134B-3|url=https://www.planelogger.com/Aircraft/Registration/VN-A120/798533|website=Planelogger|access-date = September 22, 2021))</ref>

==Accident==
((more citations needed section|date=September 2014))
Flight 815 departed Ho Chi Minh City around 1 o'clock in the afternoon for the 45-minute flight to Phnom Penh. The aircraft was approaching the Phnom Penh airport from the east in heavy rain. According to acting airport director and investigating committee chief Sok Sambour, the plane was supposed to be flying at ((Convert|14000|ft|m|abbr=)) when it began its approach, but was at ((Convert|10000|ft|m|abbr=)) when it reached the range of Pochentong's [[Non-Directional Beacon]] (NDB).

The airport previously had a [[VHF omnidirectional range|VOR]]/[[Distance measuring equipment|DME]] located on station, but it had been [[looting|looted]] the previous July.<ref>((cite news|author=Scroggins|first=Hurley|date=1997-09-26|title=Crash plane unable to use navigation gear|work=The Phnom Penh Post|url=http://www.phnompenhpost.com/national/crash-plane-unable-use-navigation-gear|access-date=2014-01-13))</ref> Because of this pilots had to use the NDB located ((Convert|5|km|mi nmi|abbr=)) west in order to get a general fix of the area, and had to keep descending until they could make visual contact with the airfield in inclement weather. As a result, the frequency of aborted landings had increased over the rainy season. The runway lights had also been looted, but were reportedly replaced and illuminated at the time.[[File:970903중앙119구조본부 베트남 항공 815편 추락 사고 출동2.jpg|thumb|Immediate aftermath of the crash]]

Once in range of the NDB, the pilot asked the control tower for permission to land at ((Convert|5000|ft|m|abbr=)). The control tower agreed, but requested the pilot remind the control tower often of its approach, due to the heavy weather. However, when the plane approached the airport it was at ((Convert|3000|ft|m|abbr=)) when the pilot again asked for permission to land, stating that he could not find the runway. The pilot was given permission to drop to ((Convert|2000|ft|m|abbr=)) and was told to keep in contact.<ref>((Cite news|url=https://www.phnompenhpost.com/national/we-cant-see-runway|title=We can't see the runway|last=Scroggins|first=Hurley|last2=Sotheacheath|first2=Chea|date=1997-09-12|work=The Phnom Penh Post|access-date=2019-12-13))</ref>

After a moment the control tower inquired if the pilot had found the runway, to which the pilot replied that he could not see the runway. The control tower then informed the pilot that the wind direction was changing. The pilot was on an eastern approach to runway 23; the tower requested that the pilot instead approach runway 5 from the west. Continuing on the eastern approach would cause the pilot to attempt to land downwind. The pilot acknowledged the request, and had no further contact with the control tower.[[File:970903중앙119구조본부 베트남 항공 815편 추락 사고 출동1.jpg|thumb|Another angle of the crash site with bodies could be seen near the wreckage|left]]Two minutes later, Flight 815 was spotted still approaching from the east. The plane kept descending until it was ((Convert|200|ft|m|abbr=)) above the ground. The [[cockpit voice recorder]] (CVR) showed at that time the first officer, Hoang Van Dinh  (49), asked the captain, Pham Van Tieu (59), to pull up and abort the landing, as they still did not have visual of the runway. The captain said he would wait a little. The plane descended to ((Convert|100|ft|m|abbr=)), still with no visual of the runway, at which point the first officer and the flight engineer, again asked the captain to abort the landing. It was too late, however; four seconds later the left wing of the plane struck a palm tree. At that time they were not in line with the runway, having veered left across the military side of the airport. Striking the tree caused one engine to stop. The right wing skimmed across a house. The plane tilted to the left and hit the ground at ((Convert|270|kph|kn mph)).

Eyewitnesses state that flames began to spew out of the plane's tail after it struck the tree. One witness states he saw an emergency door open and could see passengers crowded at the door, but none jumped before the airplane struck the ground. The aircraft then slid ((convert|200|yd|ft m|abbr=)) through several dry [[rice paddies]] before exploding at around 1:40 pm.<ref name="ppp" />

Initially Vietnam Airlines and Phnom Penh airport workers argued over who was at fault. The airline stated that the navigational equipment at Phnom Penh airport was out of order and its control tower gave the pilots incorrect information prior to takeoff.
However, the report by Cambodia's Aircraft Accident Investigation Committee determined that the cause of the crash was pilot error.<ref>((Cite web|title=AIRCRAFT ACCIDENT INVESTIGATION REPORT, VIETNAM AIRLINES, TUPOLEV RUSSIA TU-134 B-3, VN-A120, NEAR POCHENTONG INTERNATIONAL AIRPORT, 03 SEPTEMBER 1997|url=http://www.civilaviation.gov.kh/images/pdf/AIG/Accident%20Final%20Reports.pdf|access-date=2021-06-09|publisher=Aircraft Accident Investigation Committee))</ref> The report concluded that the principal factors were:
<blockquote>
* the captain did not follow the instructions of the approach controller in the control tower and he made the decision to continue to descend in very bad weather
* the captain ignored the advice of his first officer and flight engineer 
* the captain's insistence in engaging the auto pilot even after passing the minimum height at which one should decide whether or not to land
* the captain's impulsive actions to continue his approach in the conditions revealed "his psychological unreadiness to abort the landing and go around"
</blockquote>

The captain continued his landing descent from an altitude of ((Convert|6600|ft|m|abbr=)) to ((Convert|100|ft|m|abbr=)) even though the runway was not in sight, and ignored pleas from his first officer and flight engineer to turn back. When the aircraft hit the trees, the captain finally realized the runway was not in sight and tried to abort the approach; the flight engineer pushed for full power, but the aircraft lost control and veered right; the right engine then failed, making it impossible to gain lift. The aircraft subsequently stalled and crashed.<ref name="asn" />

Examinations of the aircraft and records determined that there was no mechanical problem and all maintenance was up to date. The crew all had valid licenses and medical certificates.<ref>((cite news|author=Sainsbury|first=Peter|date=1998-06-05|title=Crash victims await payout|work=The Phnom Penh Post|url=http://www.phnompenhpost.com/national/crash-victims-await-payout|access-date=2014-01-13))</ref><ref>((cite news|author=Staff|first=Post|date=1998-06-05|title=The last words of Flight 815|work=The Phnom Penh Post|url=http://www.phnompenhpost.com/national/last-words-flight-815|access-date=2014-01-13))</ref><ref>((Cite news|url=https://www.flightglobal.com/news/articles/vietnam-airlines-tu-134-crashes-on-bad-weather-approach-at-phnom-20607/|title=Vietnam Airlines Tu-134 crashes on bad-weather approach at Phnom Penh|last=Learmount|first=David|date=1997-09-10|work=[[FlightGlobal]]|access-date=2019-02-07|url-status=live|archive-url=https://web.archive.org/web/20140724221709/http://www.flightglobal.com/news/articles/vietnam-airlines-tu-134-crashes-on-bad-weather-approach-at-phnom-20607/|archive-date=2014-07-24|publisher=[[Flight International]]|location=London))</ref>
