Scheduled Revenue Flight

On 9 January 2021, a Boeing 737-500 aircraft, registration PK-CLC, was being operated by PT. Sriwijaya Air on a scheduled passenger flight from Soekarno-Hatta International Airport (WIII), Jakarta to Supadio International Airport (WIOO), Pontianak . The flight number was SJY182. According to the flight plan filed, the fuel endurance was 3 hours 50 minutes. At 0736 UTC (1436 LT) in daylight conditions, Flight SJY182 departed from Runway 25R of Jakarta. There were two pilots, four flight attendants, and 56 passengers onboard the aircraft. At 14:36:46 LT, the SJY182 pilot contacted the Terminal East (TE) controller and was instructed “SJY182 identified on departure, via SID (Standard Instrument Departure) unrestricted climb level 290”. The instruction was read back by the pilot. At 14:36:51 LT, the Flight Data Recorder (FDR) data recorded that the Autopilot (AP) system engaged at altitude of 1,980 feet. At 14:38:42 LT, the FDR data recorded that as the aircraft climbed past 8,150 feet, the thrust lever of the left engine started reducing, while the thrust lever position of the right engine remained. The FDR data also recorded the left engine N1 was decreasing whereas the right engine N1 remained. At 14:38:51 LT, the SJY182 pilot requested to the TE controller for a heading change to 075° to avoid weather conditions and the TE controller approved the request. At 14:39:01 LT, the TE controller instructed SJY182 pilot to stop their climb at 11,000 feet to avoid conflict with another aircraft with the same destination that was departing from Runway 25L. The instruction was read back by the SJY182 pilot. At 14:39:47 LT, the FDR data recorded the aircraft’s altitude was about 10,600 feet with a heading of 046° and continuously decreasing (i.e., the aircraft was turning to the left). The thrust lever of the left engine continued decreasing. The thrust lever of the right engine remained. At 14:39:54 LT, the TE controller instructed SJY182 to climb to an altitude of 13,000 feet, and the instruction was read back by an SJY182 pilot at 14:39:59 LT. This was the last known recorded radio transmission by the flight. At 14:40:05 LT, the FDR data recorded the aircraft altitude was about 10,900 feet, which was the highest altitude recorded in the FDR before the aircraft started its descent. The AP system then disengaged at that point with a heading of 016°, the pitch angle was about 4.5° nose up, and the aircraft rolled to the left to more than 45°. The thrust lever position of the left engine continued decreasing while the right engine thrust lever remained. At 14:40:10 LT, the FDR data recorded the autothrottle (A/T) system disengaged and the pitch angle was more than 10° nose down. About 20 seconds later the FDR stopped recording. The last aircraft coordinate recorded was 5°57'56.21" S 106°34'24.86" E. At 14:40:37 LT, the TE controller called SJY182 to request for the aircraft heading but did not receive any response from the pilot. At 14:40:48 LT, the radar target of the aircraft disappeared from the TE controller radar screen. At 14:40:46 LT, the TE controller again called SJY182 but did not receive any response from the pilot. The TE controller then put a measurement vector on the last known position of SJY182 and advised the supervisor of the disappearance of SJY182. The supervisor then reported the occurrence to the operation manager. The TE controller repeatedly called SJY182 several times and also asked other aircraft that flew near the last known location of SJY182 to call the SJY182. The TE controller then activated the emergency frequency of 121.5 MHz and called SJY182 on that frequency. All efforts were unsuccessful to get any responses from the SJY182 pilot. About 1455 LT, the operation manager reported the occurrence to the Indonesian Search and Rescue Agency (Badan Nasional Pencarian dan Pertolongan/BNPP). At 1542 LT, the Air Traffic Services (ATS) provider declared the uncertainty phase (INCERFA) of the SJY182. The distress phase of SJY182 (DETRESFA) was subsequently declared at 1643 LT.

The aircraft departed Djibouti on a regular schedule service to Mogadishu with intermediate stops in Hargeisa and Garowe. There were 31 passengers and 8 crew members on board. On short final approach to Garowe Airport Runway 06, the aircraft was too low, causing the right main gear to struck the ground just short of runway threshold (concrete). The right main gear collapsed and the airplane slid on the runway until it turned to the right and came to rest on the runway with the right engine cowling contacting the runway surface. All 39 occupants evacuated safely and the aircraft was damaged beyond repair.

On 22 May 2020 at 13:05 hrs PST, the Pakistan International Airlines aircraft Airbus A320-214, registration number AP-BLD, took off from Lahore (Allama Iqbal International Airport – AIIAP) Pakistan to perform a regular commercial passenger flight (PK8303) to Karachi (Jinnah International Airport – JIAP) Pakistan, with 8 crew members (01 Captain, 01 First Officer, and 06 flight attendants) and 91 passengers on board. At 14:35 hrs the aircraft performed an ILS approach for runway 25L and touched down without landing gears, resting on the engines. Both engines scrubbed the runway at high speed. Flight crew initiated a go-around and informed “Karachi Approach” that they intend to make a second approach. About four minutes later, during downwind leg, at an altitude of around 2000 ft, flight crew declared an emergency and stated that both engines had failed. The aircraft started losing altitude. It crashed in a populated area, short of runway 25L by about 1340 meters. An immediate subsequent post impact fire initiated. Out of 99 souls on-board, 97 were fatally injured and 02 passengers survived. On ground 04 persons were injured however 01 out of these reportedly expired later at a hospital.

Below, the preliminary report published by the Pakistan AAIB.

Following an uneventful flight from Moscow-Vnukovo Airport, the crew initiated the descent to Usinsk Airport Runway 13. On short final, the aircraft hit a snow bank (1,1 metre high) located 32 metres short of runway threshold, still on the concrete zone. Upon impact, both main gears were torn off and the airplane belly landed and slid for few hundred metres before coming to rest. All 100 occupants evacuated safely and the aircraft was damaged beyond repair.

Following an uneventful flight from Izmir-Adnan Menderes Airport, the crew initiated the approach to Istanbul-Sabiha Gökçen Airport runway 06. Weather conditions were poor with thunderstorm activity, rain, CB's and a wind from 290 gusting to 37 knots. After touchdown on a wet runway, the airplane was unable to stop within the remaining distance. It overran, turned slightly to the left then went down an embankment (25 meters high) and came to rest, broken in three. Three passengers were killed while all 180 other occupants were evacuated to local hospitals. It is understood that the airplane apparently landed 1,500 meters past the runway threshold (runway 06 is 3,000 meters long) with a non negligible tailwind component that must be confirmed.

On Jan. 27, 2020, at 03:12 UTC Caspian Airlines (CPN) Flight 6936, an MD83, EP-CPZ took off from Mehrabad International Airport and climbed to FL320 as final cruising level. At about 03:45:37 UTC, the aircraft was flying according to the flight plan route on Airway B417 at an assigned FL320. Due to another traffic departing flight, an A320, IRA356 from Abadan Airport (OIAA) to destination Mashhad International Airport (OIMM), the ACC controller issued direct routing to the flight CPN 6936 position GODMO. At 03:49:34 UTC, CPN6936 requested descent clearance, so the flight was cleared to FL100. At 03:52:30 UTC, the pilot called Mahshahr AFISO and reported position 50 nm inbound GODMO and estimated time over GODMO at 03:59 UTC. At 03:52:51 UTC, Mahshahr AFISO reported necessary information as below: "RWY active is 31; wind is now 280/08kts, CAVOK, temperature +06, DP 04 and QNH 1023, expected VOR approach RWY 31 via GODMO 1E ARRIVAL" At 03:53: 33 UTC, the pilot requested RWY 13 and Mahshahr AFISO performed VOR/DME approach RWY 13, via GODMO 1F arrival. At 03:59:39 UTC, the pilot reported, “we are approaching position GODMO in contact with destination Mahshahr.” At 04:00:41UTC, the pilot reported his position “GODMO” to Mahshahr AFISO. At 04:02:46 UTC, the pilot reported leaving of IAF and received landing clearance for RWY13. Finally, at 04:06:11 UTC, the aircraft landed on RWY 13, passed two-thirds of RWY length and ran off the end of runway13 after landing at Mahshahr Airport at 04:06 UTC, Khuzestan province. The accident flight was being operated on an Instrument Flight Rules (IFR) flight plan in a Visual Meteorological Condition (VMC). The main door of the accident aircraft was opened in emergency condition, but the slide skid did not operate automatically. The cabin floor was just too close to the ground (grass surface) due to the impact of the nose and main landing gears strut which were broken after the runway overrun. The evacuation was performed from the main door, and all 136 passengers and 8 crew members disembarked.

On Wednesday, January 08, 2020, at 00:53, the inbound flight No. 751 of Ukraine International, Boeing 737-800, UR-PSR, en route to Tehran Imam Khomeini INTL. Airport from Kyiv Boryspyl INTL. Airport was cleared for landing, and after four minutes landed on the IKA runway. After disembarking 58 passengers and refueling, the flight crew went on to check into the hotel located at IKA. From 01:16 to 01:38, the aircraft was refueled with 9510 kg (11800 liters) of fuel. Once the total weight of the cargo received from passengers (310 packages weighing 6794 kg) was determined, in order to comply with the maximum takeoff weight allowed for aircraft, 82 packages in 2094 kg in weight, were separated by Airport Service Company, that is, they were not loaded. Initially, 78 packages of the passenger's luggage were not loaded first, then due to the large volume of passengers' hand luggage, the flight attendants passed some of them on to the Airport Service Company personnel to be placed in the aircraft cargo. After that, 4 packages belonging to the passengers were removed from the aft cargo door, where the hand luggage was placed. At 04:35, the flight crew embarked on the aircraft. After checking the aircraft and cabin, boarding was announced at 04:45, and passengers started to board the plane. Based on the available documents, 167 passengers proceeded to the Airport Services Co. counter at the airport terminal, all of whom went on board. Only one of the passengers who received the boarding pass online the night before the flight, due to the delay in arriving in Tehran from another city did not go to the airport in person, and therefore had been removed from the list of passengers provided by the UIA. At 05:13, the pilot made his first radio contact with the IKA's control tower ground unit and requested the initial clearance for flying, which was issued by the controller subsequently. At 05:48, all the aircraft documents required to start the flight operations were filled out, and all the doors were then closed at 05:49. The flight was initially scheduled for 05:15, and based on the flight coordinator's report form, the reason given for its delay was the aircraft being overweight and the decision not to load the passengers' lugga for reducing the aircraft weight. At 05:51 the pilot notified his position at the airport parking, declared his readiness to exit the parking and start up the aircraft. The IKA tower asked him to wait for receiving the clearance since they wanted to make the coordination required with other relevant units. At 05:52, the IKA tower made the necessary coordination with the Mehrabad approach unit, who contacted Tehran ACC asking for clearance. Accordingly, the controller in ACC made coordination on Ukrainian flight clearance with the CMOCC. The clearance was issued by the CMOCC. At 05:54, the Mehrabad approach unit, received the FL260 clearance for the flight AUI752 from ACC, and forwarded it to IKA via the telecommunication system. Flight no. 752 was detached from the A1 Jet Bridge and at about 05:55 started to leave its parking position, NO 116 on the right, by a pushback truck. Following that, at 05:55 the ground controller cleared the AUI752 flight for startup and exiting the parking, which was read back by the pilot. At 06:12, the aircraft took off from the Runway 29 Right of IKA and was delivered to the Mehrabad approach unit. The pilot contacted the approach unit, and announced the IKA 1A radar procedure as SID procedure. Next, the Mehrabad approach identified and cleared the flight to climb to FL260. The controller instructed the pilot to turn to the right after 6,000 feet, and continue straight to PAROT. After it was read back by the pilot, the controller again instructed the pilot to continue to PAROT point once passing the 6000-foot altitude, which was read back by the pilot. From 06:17 onwards, upon the disappearance of the PS752 information from the radarscope, the controller called the captain repeatedly, but received no response. According to the data extracted from the surveillance systems and FDR, the aircraft climbed to an altitude of 8,100 feet; thereafter, the label including the call sign and altitude of aircraft disappeared from the radarscope, yet no radio contact indicating unusual conditions was received from the pilot. FDR recording terminated at 06:14:56. This time corresponds to the termination of Secondary Surveillance Radar (SSR) and ADS-B information. After the mentioned time, the aircraft was still being detected by the Primary Surveillance Radar (PSR), according to which the aircraft veered right and after approximately three minutes of flying, it disappeared from the PSR at 06:18 too. The aircraft was conducting the flight under the Instrument Flight Rules (IFR) and the accident occurred around half an hour before the sunset.

After touchdown on a wet earth runway, the airplane went out of control. It veered off runway to the right, struck a shoulder and lost its nose gear before coming to rest. All 18 occupants escaped uninjured while the airplane was substantially damaged.

The Fokker 100 departed Almaty Airport on a regular schedule service (flight Z92100) to Astana-Nursultan Nazarbayev Airport, carrying 93 passengers and a crew of five. During the takeoff roll on runway 05R with flaps at zero, after a course of 36 seconds and at a speed of 148 knots, the crew started the rotation. Immediately after liftoff, the airplane rolled to the right at an angle of 5° then to the left at an angle of 19° without an increase of the indicated airspeed. After reaching the height of 20 feet in a pitch angle of 14°, the airplane started to descend then hit the runway surface with the base of the tail. It landed on its main landing gear and rolled for about 15 seconds with the nose gear still in the air. The airplane took off again at a speed of 138 knots then the crew retracted the landing gear. In a pitch angle of 19°, the airplane lost speed (130 knots), veered to the right, belly landed and slid for about 850 metres, went through a fence and eventually crashed into a house located near the perimeter fence, some 80 metres to the right of the extended center line. 47 occupants were injured, 39 escaped unhurt and 12 others were killed, among them the captain. The aircraft was destroyed. There was not fire.

The single engine airplane departed Hermosillo-General Ignacio Pesqueira García Airport at 0700LT on a schedule service (CFV872) to Guerrero Negro, Baja California del Sur, with one passenger and one pilot on board. About half an hour into the flight, radio and radar contact were lost with the airplane. Debris were found two days later in an uninhabited area located in the region of Tastiota, about 30 km southwest of Miguel Alemán. The aircraft was totally destroyed upon impact and both occupants were killed.
