A tragic accident happened with a mechanic at Chabahar Konark Airport in Iran. Actually, the mechanic realized that he had forgotten a tool on the engine, and before the engine caught fire, he went to the plane to get the tool, then he got inside the turbine. The fire brigade has been reported to have recovered his remains after reaching the spot.

A mechanic became stuck in the engine of a Boeing plane at Chabahar Konark Airport in Iran. This incident is reported on July 3. Reports say Abolfazl Amiri was sucked into the engine of Varesh Airlines' Boeing 737-500 when he went to the plane to get the engine-related tool. The engine was on a test run.
The aircraft flew in from Tehran at 7.15 am on July 3, and the passengers had alighted when the right engine was started for the test run. The cover flaps were open, and a safety zone ringed the device around the engine. He then realized he had left a tool on the engine and went to the plane to get the tool, after which it caught fire when he got inside the turbine. He died in this. His remains have been reported to have been recovered by the fire brigade at its arrival at the spot.
It is known that on the morning of 3 July, one of the specialists of Varesh Airlines, during the powering up of the pilot for reasons that require investigation and analysis by air accident experts at the scene of the accident, suddenly found himself in the air suction path of the engine intake, and was drawn into the CFM56-3 turboprop engine mounted on the Boeing 737.
This would not be the first case of an individual getting stuck in the engine of an aircraft. A person died in May by getting stuck in the engine of a KLM Cityhopper Embraer E190 at Amsterdam's main airport. This happened in front of many passengers, with a person being caught in the engine. Today at Schiphol, a horrific incident took place in which a man was trapped inside the engine of a moving plane.
