Circumstances:
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.
Probable cause:
Cause of the Accident:
- The air defense's launching two surface-to-air missiles at the flight PS752, UR-PSR aircraft the detonation of the first missile warhead in proximity of the aircraft caused damage to the aircraft systems and the intensification of damage led the aircraft to crash into the ground and explode instantly.

Other Contributing Factors:
- The mitigating measures and defense layers in risk management proved to be ineffective due to the occurrence of an unanticipated error in threat identifications, and ultimately failed to protect the flight safety against the threats caused by the alertness of defense forces.

Circumstances:
On August 10,2014, at 04:52 UTC daylight time, an AN-140-100 aircraft , Iranian registration EP-GPA ( MSN 90-05), operated by Sepahan Airlines flight # 5915, experienced engine number 2 shutdown just about 2 seconds before lift-off and crashed shortly after take-off nearby Mehrabad International Airport (THR), TEHRAN; IR. Of IRAN; the aircraft was on lift off from runway 29L. The airplane was completely destroyed by impact forces and post-crash fire. Fatality incorporates 34 of the 40 passengers; 4 of the 4 flight attendants, and 2 of the 2 flight crewmembers. The 11 passengers received serious injuries, which finally as a result of that accident there are 40 fatalities and 8 passengers recovered from injury. Sepahan Airline was operating under the provisions of CAO.IRI operational requirement for commercial air transport. Before the accident flight the airplane dispatch from Isfahan and arrived at Tehran about 03:30. The dispatcher and PIC perform the load calculation using the aircraft FM performance charts. Because of load limitation for 15° flap position, load sheet change and re-write with 10° flap position and re-calculated MTOM. The aircraft was enrouted to Airport Tabbas Visual meteorological conditions (VMC) prevailed, and an instrument flight rules (IFR) flight plan was filed. Figure 1 below is a map showing the location of the accident and the aircraft flight path. Figure 2 shows THR runway 29L SID and figure 3 show timeline of event in the flight path. According to overview of flight crew performance, it is indicated that the crewmembers were provided with the flight release paperwork, which included weather information, notices to airmen (NOTAM), and the flight plan.
Probable cause:
The accident investigation team determined that the main cause of this accident was combination of:
1. Electronic engine control (SAY-2000) failure simultaneously with engine No: 2 shutdown, just about 2 seconds before aircraft lift-off.
2. AFM Confusing performance chart resulted the pilots relying on performance calculation that, significantly over-estimate the aircraft MTOM.
Contributing Factors to the accident were:
1. Aircraft flight manual unclear procedure, including the procedure for calculating maximum allowable take-off weight, VR and V2 and ambiguity in the climb segment definition and applications.
2. Crew performance, including:
- PIC rotated the aircraft at the speed of about 219 km/h (whereas 224 km/h is the speed recommended by the AFM table 4.2.3),
- The crew failed to perform the manual propeller feathering procedure for the failed engine,
- The PIC's decision to fly with the aircraft, notwithstanding, had about 190 kgf overweight,
- Aircraft fuel was about 500 kg more than required fuel for the accident flight.
3. The appearance of negative thrust from the unfeathered propeller blades at takeoff were not considered during the aircraft certification tests, as it was considered improbable. However, in
the accident flight the negative thrust did appear and affected the flight performance.

Circumstances:
While preparing the flight at Tehran-Mehrabad Airport, the copilot proceeded with a walk around check of the airplane. As the OAT was near freezing level and there were some light snow showers, he requested a deicing. Nevertheless, as there were already a few number of aircraft waiting for deicing, the captain decided to takeoff without deicing. At 0731LT, the crew was cleared for takeoff and started the takeoff procedure. After liftoff, the aircraft started to roll to the left then to the right. Losing altitude, the left wing impacted ground and the aircraft crash landed, coming to rest and bursting into flames. All 113 occupants were rescued, among them 11 were seriously injured including four crew members.
Probable cause:
It was determined that the accident was the consequence of an aerodynamic stall after lift off due to a loss of lift because the wings were contaminated and that the aircraft had not been deiced prior to takeoff.
The following contributing factors were identified:
- Poor crew resources management,
- Poor flight preparation,
- Lack of knowledge about winter operations on part of the operator.
