Ukraine International Airlines flight 752, a Boeing 737-800, crashed near Sabashahr, 7 minutes after takeoff from Tehran Imam Khomeini International Airport, Iran. Al 167 passengers and nine crew members on board were killed.
The Boeing 737-800, registration UR-PSR, had landed on schedule at 00:57 hours local time at Tehran. The return leg back to Kiev was due to depart at 05:15 local time (01:45 UTC).

In the meantime, around 02:15 hours local time in Iran, numerous ballistic missiles were fired from Iran towards U.S. bases in Iraq in response to the killing of Major General Qasem Soleimani by a United States drone strike.
As a result this military operation changed the alertness level of Iran’s air defense. At approximately 04:00 the military sector informed the civil sector of the country’s Airspace Control that only the flights already detected and cleared for flight operations by the defense network could be permitted to start up. This would ensure the correct identification of civil flights by the defense network and avoiding targeting them by mistake.

At 05:49 the doors were closed and the aircraft was ready to depart. Two minuts later the flight requested the to start up the engines.

After contacting the Area Control Center, the ATC unit requested clearance for the Ukrainian flight at 05:52. The Area Control Center forwarded the request for flight PS752 to the Air Defense Coordination Center, which subsequently issued the clearance accordingly.

The aircraft then taxied to runway 29R and commenced the takeoff roll at 06:11. After takeoff the flight contacted Mehrabad Radar and was cleared to climb to FL260 and turn right after reaching 6000 feet, heading direct to the PAROT reporting point.
As the aircraft was climbing after departure, it appeared on the air defense system. However, a wrong initialisation procedure of the system’s north alignment had induced a 107-degree error in the system. Thus, the direction of objects and targets detected by this system was being observed with an increase of 107 degrees by the operator.
At 06:13:56, the air defense unit operator detected a target at his 250-degree azimuth, flying on a 52-degree course. At the same time, PS752 had been flying towards the defense system from a 143-degree azimuth. The aircraft was flying a 309-degree course.

At 06:14:21, the operator notified the specifications of the detected target to the Coordination Center over the communication network. The notification was not communicated successfully.

Meanwhile the system operator began analyzing the observable information and categorized the detected target as a threat. At 06:14:41, without receiving any response from the Coordination Center, the air defense unit operator fired a missile at the threatening target he had detected.

Under the applicable procedures, if the defense system operator cannot establish communication with the Coordination Center and does not receive the fire command, they are not authorized to fire.

The missile radio fuse was activated at 06:14:59. At that point flight PS752 was at 8100 feet at a position about 20 km west-northwest of the airport.

After the first missile radio fuse was activated, the air defense unit radar still locked on the target, and the defense system kept detecting and tracking it. By observing the continuity of trajectory of detected target, the second missile was fired at the aircraft by the operator of defense system at 06:15:11.

At 06:45:24, the last communication between the missile and the defense system was recorded in a place close to the aircraft route. After that, the defense system showed a message indicating the strike had failed, with the aircraft clearing from the radar lock-on after some time.

The aircraft turned to the right and about 06:16:11, a fire broke out on the aircraft, which was intensifying. Altitude was lost and at 06:18:23, the aircraft crashed into a playground in Khalajabad near Shahedshahr area, 15 km north of the airport. It disintegrated completely and wreckage was strewn along a 300 m long path.

Air India flight was at full speed while landing at Calicut Airport: DGCA

An Air India Express flight with over 190 passengers and crew members onboard skidded off the runway at the Kozhikode International airport in Kerala on Friday evening. DGCA officials told news agency ANI that the Dubai-Kozhikode aircraft was at “full speed” while landing at the Karipur Airport and overshot the runway.

At least 19 were killed after an Air India Express flight with over 190 passengers and crew members onboard skidded off the tabletop runway at the Kozhikode International airport in Kerala, also known as the Karipur Airport, on Friday evening.

The Air India Express flight skidded off the tabletop runway and fell into a 35-ft-deep valley breaking up into two parts on Friday evening, police sources said.

Both pilot and the co-pilot are among the 19 killed in the flight mishap.

The flight was coming from Dubai and was part of India’s Vande Bharat mission, an initiative to bring back stranded Indians from foreign countries.

The fuselage broke into two after the aircraft overshot the runway at Kalipur airport. The aircraft has been identified as IX 344.

Civil Aviation Minister Hardeep Singh Puri said that the flight, on its way from Dubai to Kozhikode, “overshot the runway in rainy conditions and went down 35 ft into a slope before breaking up into two pieces”.

“Weather conditions being what they are, I’m told aircraft couldn’t be brought to a halt. As a tabletop airport, it imposes a challenge. There was a 30-feet drop to the ground below. Fortunately, the plane that broke into two from fuselage didn’t catch fire,” Hardeep Singh Puri told India Today TV.ADVERTISEMENT

Directorate General of Civil Aviation (DGCA) told news agency ANI that the Dubai-Kozhikode aircraft was at “full speed” while landing at the Karipur Airport and overshot the runway.

Inputs suggest that a missed approach was carried out first followed by a second attempt to land the aircraft when it overshot the runway.

The Kozhikode is a tabletop airport with deep gorges at both ends of the runway. The tabletop runway of the Kozhikode airport is said to be one of the riskiest runways for landings in India.


Air India Express B737-800, suffered a runway excursion on landing at Kozhikode-Calicut Airport, at least 17 fatalities

Air India Express flight 1344, a Boeing 737-800, suffered a runway excursion on landing at Kozhikode-Calicut Airport, India. Local media report at least 17 fatalities.
The flight departed Dubai Airport, United Arab Emirates at 10:15 UTC on a passenger service to Kozhikode-Calicut Airport.
The aircraft arrived from the west, overflying the airport at 13:42 UTC. It then performed a teardrop approach to runway 28. This approach was discontinued and the aircraft subsequently flew a teardrop approach to runway 10. The aircraft touched down at 14:11 UTC (19:41 local time) but reportedly suffered a runway excursion. Photos from the scene show the nose section had separated from the fuselage after the aircraft went down a slope.

DGCA officials told news agency ANI that the Dubai-Kozhikode aircraft was at “full speed” while landing at the Karipur Airport and overshot the runway.

Weather at the time of the approaches and landing was poor. At 14:00 UTC scattered clouds were reported at 300 and 1200 feet with a few Cumulonimbus clouds at 2500 feet and overcast clouds at 8000 feet. The wind was from 260 degrees at 12 knots. Visibility was 2000 m in rain.

Airport and runway
The airport has a single runway (10/28) which is located on a flattened hill. The Landing Distance Available (LDA) for both directions is 2850 m. The runway strip extended to 60 m beyond the threshold. After the paved surface, there is a runway end
safety area (RESA), measuring 93 m x 90 m. The ICAO required RESA length is 90 m, whereas the recommended length is 240 m.
Past the RESA there is a 35 m drop off.

Reckless pilot flies with one engine, ignores regulations


Czech Air Accidents Investigation institute (or UZPLN) released a final report revealing that the pilot in command of a Smartwings Boeing 737-800 deliberately ignored engine failure mid-flight and his co-pilot’s continuous assertions to land, and proceeded to the flight’s original destination.

On August 22, 2019, a Smartwings Boeing 737-800, registration OK-TVO performed the flight QS-1125 from Samos (Greece) to Prague (Czech Republic) with 170 people on board. The aircraft was over the Aegean Sea northeast of Athens (Greece) when it drifted down to FL240 and continued to Prague at the same altitude before landing 2 hours later without incident.

Reportedly, this sudden drop in altitude was the consequence of a spontaneous shutdown of one of the aircraft’s engines. The onboard crew attempted to relight the engine twice using different methods but without any success. Due to tankering, the aircraft had a sufficient amount of fuel to make the journey, prompting the captain to continue towards Prague.

According to the investigator’s report, this course of action was an “obvious disregard and violation of applicable Operation Manual Air Traffic Procedures as well as applicable regulations, provisions and safety recommendations,” especially when it was revealed that the first officer stressed to land within the first two minutes following engine failure. The captain refused to comply with Cockpit Resource Management, rendering his co-pilot incapable of participating in the decision-making process.

According to the report, the captain could not have known whether the shutdown was due to contaminated fuel and failed to adopt a safety strategy if the second engine failed as well.

If, for any reason, the aircraft would have needed to divert from Prague to its alternative, the captain would have been required to declare mayday as the fuel reserves were insufficient for single-engine operation. Luckily the aircraft carrying 170 passengers landed safely in Prague and was cleared for service a mere 17 hours later.

According to the UZPLN, the captain on board during the flight continues to believe that his decision-making process was carried out correctly. The investigators recommended Smartwings to perform a psychological examination of the captain at the Institute of Aviation medicine in Prague.
