Scheduled Revenue Flight

During the last segment on approach to Ho Chi Minh-Ville-Tan Son Nhat Airport, at a height of about 30 feet, the aircraft lost height, causing the left main gear to struck the ground short of runway threshold. The aircraft then landed hard and came to a halt on the main runway. All 79 occupants were evacuated, among them five passengers were injured.

On final approach, the crew failed to realize his altitude was insufficient when the aircraft struck an embankment located 60 meters short of runway threshold. The nose gear was torn off and after touchdown, the aircraft veered off runway and came to rest, bursting into flames. All 43 occupants were rescued, among them 13 were injured.

On December 3, 1990, at 1345 est, Northwest flight 1482, a DC-9 (N3313L), and Northwest flight 299, a Boeing 727 (N278US), collided near the intersection of runway 09/27 and 03C/21C in dense fog at Detriot-Metropolitan-Wayne County Airport, MI. At the time of the collision, the B-727 was on its takeoff roll, and the DC-9 had just taxied onto the active runway. The B-727 was substantially damaged, and the DC-9 was destroyed. Seven of the 40 passengers and 1 crew member aboard the DC-9 received fatal injuries. None of the 146 passengers and 8 crewmembers aboard the B-727 were injured.

Following an uneventful flight from Krasnoyarsk, the crew started the approach to Dikson by night and marginal weather conditions. On short final, the aircraft was too high and landed too far down the runway with a tailwind component and at an excessive speed. Unable to stop within the remaining distance available, the aircraft overran, went through an embankment at a speed of 115 km/h and eventually came to rest in a ravine. All 35 occupants were rescued, among them 8 were injured. The aircraft was damaged beyond repair.

On final approach to Koh Samui Airport runway 35, the aircraft entered an area of heavy rain falls. As the crew was unable to locate the runway, the captain decided to initiate a go-around procedure. With flaps fully extended, the crew increased power and started to gain height when the aircraft rolled to the left to an angle of 75° then entered an uncontrolled descent and crashed at a speed of 147 knots about 5 km short of runway threshold. The aircraft disintegrated on impact and all 38 occupants were killed.

Following an uneventful flight from Moscow-Domodedovo Airport, the crew started the approach to Yakutsk-Intl Airport. Due to poor weather conditions and a visibility below minima, the crew diverted to Magan Airport. The aircraft overflew the runway threshold at a height of 22 meters and a speed of 297 km/h. It 'floated' for 22 seconds and eventually landed 1,647 meters past the runway threshold. For unknown reasons, the captain maintained the aircraft in a nose-up attitude and the nose gear landed nine seconds after the first touchdown only. Reverse thrust were not activated and the spoilers were finally deployed but too late. At a distance of 47 meters from the runway end, the captain shut down all four engine when the aircraft overran at a speed of 167 km/h. It went down an embankment, lost its undercarriage and came 538 meters past the runway end, 3,978 meters from the runway threshold and 2,331 meters from the touchdown point. Four passengers were injured and 185 other occupants were evacuated safely. The aircraft was damaged beyond repair.

The twin engine aircraft christened 'El Isleño' departed Quibdó-El Caraño Airport at 1243LT on a flight to Bogotá, carrying 12 passengers and for crew members. While cruising at an altitude of 11,500 pieds, the crew encountered poor weather conditions when the aircraft struck the slope of Mt San Nicolás. The wreckage was found few hours later and all 16 occupants were killed.

On the 14th November 1990 ALITALIA flight 404, aircraft type DC-9-32 registration I-ATJA, took off from runway 36R at LIN bound for ZRH. The flight was a scheduled commercial flight. The clearance was to the destination airport Zürich, via a CANNE IC departure to Flight Level 120, the transponder code 0302. The PIC assumed the duties of assisting pilot and dealt with the radio-telephony. The First Officer was the handling pilot. The take-off was at 1836 hrs. The standard climb via CANNE towards Airway A9 to the cruising flight level of 200 was trouble free. About 2 minutes after reaching Flight Level 200 the crew listened to Zürich VOLMET. From this they gathered that the surface wind at Zürich was 240/08 kt. This led the PIC forsee a landing on runway 28. Having heard from the ATIS that the landing runway was 14, the crew still discussed a right hand circling approach for a landing on runway 28. The discussion continued considering a left hand circling to runway 28. At 1852.53 hrs, from a QNH of 1019 hPa the crew worked out a QFE of 970 hPa. During the descent, the crew discussed the approach procédure for runway 14, where the Copilot mentioned the Outer Marker height for runway 16. After the discussion about the setting of the navigation aids, they also discussed the procédure to be followed in the event of a communications failure. The crew were instructed that following radar vectors they should fly an ILS approach to runway 14. At 1900.01 hrs the Copilot said "We perform a CAT JJ (approach)". The PIC was in agreement because the navigation equipment had to be checked. Whilst verifying the décision height, it transpired that the Copilot was still Consulting the approach chart for runway 16. Further lengthy discussions about the setting of the required navigation aids followed. As the aircraft passed abeam Zürich descending to Flight Level 90, the PIC noted: "We are by KLOTEN, FL 90. He is bringing us in high". Clearance to descend to Flight Level 60 followed at 1902.28 hrs. At 1902.50 hrs ALITALIA 404 was instructed to fly heading 325. VHF NAV 1 was tuned to Trasadingen VOR (TRA), VHF NAV 2 to Kloten VOR (KLO). To define the fix at EKRON, the course 068 was also set. At 1904.32 hrs the PIC repeated "The outer marker is at 1200 ft (QFE), it can be verified by 3.8 [NM] from Kloten. Rhein (RHI NDB) 5.6 [NM]...". At 1905.15 hrs a new heading was required which the PIC confirmed. The identification of the ILS - 14 was registered on the CVR at 1905.32 hrs. At 1906.20 hrs, together with the approach clearance to runway 14, a new heading of 110, descent to 4000 ft and the QNH of 1019 hPa was given. The PIC confirmed this clearance, however the heading was read back as 120. The incorrect readback of the clearance by the PIC caused the Copilot some uncertainty of the required heading to be flown. The PIC confirmed the approach clearance and the cleared altitude 4000 ft to the COPI, whereby the COPI ordered "RADIO APPROACH...". At this point an altitude of about 5000 ft (QNH) was passed. One of the pilots asked the other whether he had a Glide Path indication. The aircraft position was just before interception of the Localiser passing an altitude of about 4700 ft (QNH) (according to radar and DFDR). It was already about 1300 ft below the Glide Path. Answering the question about the Glide Path, the other pilot replied (hardly understandable) "On 1...I don't have...." Consequently the PIC said: "Good, so let's do it on 1". The COPI then ordered "RADIO 1". The flaps were probably set to 15°. In the meantime, the aircraft had passed through the localiser and was now slightly east of it. About the same time as the PIC said "Capture LOC capture glide path capture - so we are on the localiser, a little off track but..." (translated from Italian) the aircraft descended through 4000 ft (QNH) (about 11.5 NM from the threshold runway 14). It was thus about 1200 ft below the glide path. The QFE 970 hPa was also set by the COPI. About 5 seconds later the Altitude Exit Alert was heard (Descent through 3700 ft [QNH]). The PIC cancelled the warning by setting 5000 ft (Go Around Altitude) on the Altitude Preselect. The PIC said to the COPI: "There is another one (Finnair 863) in front quite close. You can reduce even further to 150 (kt) otherwise we'll end up with a "go around". A discussion followed about possible icing. After this the flaps were set to 25 during which no Landing Gear horn was heard. At this point the aircraft was established on the localiser. The altitude was about 3000 ft QNH - ca. 1200 feet below the glide path. The PIC: "Outer Marker check is at 1250 ft [QFE]". The height was now about 1600 ft QFE. 10 seconds after Flaps 25, the flaps were set to 50. The Outer Marker height of 1250 ft QFE was now passed. The PIC said "Bravo" followed by sounds of switching. At 8 NM final the PIC mentioned "3.8 almost 4 miles". At about 7 NM final, (15 seconds after the PIC's words "Almost 4 miles") the COPI asked "... haven't we passed it?". After a further 12 seconds the COPI asked once again "Didn't we pass the outer marker?" The height was now 670 ft QFE. The PIC's answer was "No no it hasn't changed yet. At 6.6 NM final the PIC said "Oh it shows 7 The crew was now ordered by Zürich ARR to change frequency to Zürich TWR. At 6.25 NM final the pilots conversed as follows: "... That doesn't make sense to me "Nor to me ...". 2 seconds after this conversation the PIC called out "Pull, pull, pull, pull! ". Simultaneously autopilot disconnection could be heard. The position was now about 500 ft AGL overhead Weiach - about 350 ft QFE. 2 seconds later the COPI called out "GO AROUND" the PIC responded with "No no no no ... catch the glide". At this point the DFDR shows a pitch change from -2° [AND] to +5.4° [ANU]. At the same time the thrust was increased from 1.3 to 1.7 EPR. The sink rate decreased from 1100 ft/min. to 190 ft/min. After 11 seconds (the pitch oscillated at +1° [ANU]) the PIC asked "Can you hold it?" to which the COPI replied "Yes". One second after the COPI's answer the Radio Altimeter warning (pip pip pip) indicating 200 ft/AGL could be heard. During this, the PIC said "Hold on let's try to At 1911.18 hrs the aircraft Struck the north em slope of the Stadlerberg at a altitude of 1660 ft QNH. All 46 occupants were killed.

Crashed in unknown circumstances on a mountain located near Escalera. All 12 occupants were injured.

The descent to Santiago de Cuba-Antonio Maceo Airport was started by night and poor weather conditions. As the crew was unable to locate the airport, he decided to abandon the approach and initiated a go-around. Few minutes later, a second attempt to land was also abandoned. During the third approach completed under VFR mode, the crew failed to realize he was not properly aligned when the aircraft struck at a speed of 280 km/h the top of a hill and crashed 4 km short of runway 27. Two crew members and 9 passengers were killed while 20 other occupants were rescued, among them 12 were seriously injured.
