The reason for the stars' emergency landing: new discoveries from the investigation of the failures in the owl helicopters

The details of the investigation into the crash in the chief of staff's helicopter that made an emergency landing last month show that the plane's engine was contaminated with corrosion, apparently due to moisture accumulating in it. Corps officials are examining whether the helicopters are being held at Palmachim base. "Proximity to sea accelerates wear and tear."

New findings from the Air Force's investigation into a series of technical faults in the Owl (Blackhawk) helicopters shed light on the emergency landing on Chief of Staff Aviv Kochavi's flight last month. The details of the investigation reached Walla! NEWS, the fault was probably due to accumulation of engine corrosion. generally high humidity. air Force officials said they have also examined the proximity of helicopters into the sea, because the pilot location Palmachim base on the beach.

details of the investigation indicate that the helicopter of the stars on July 8 defined by squadron 124 C"hmorh. "this is because After taking off from the "Elder" landing pad, at a height of one hundred meters above the ground, the air crew experienced a "compressor stand", accompanied by an explosion and continuous buzzing from the engine area.

Following the explosion and buzz, the helicopter pilot decided to make the coffee in the air, with a crew meanwhile identifying one engine malfunctioning. The pilot decided to reduce the load on the other engine, resulting in a RPM (engine speed per minute) decreased, but the heat in the engine increased. Due to this, the pilot decided to replace throttles and make an emergency landing, when only a single engine was running. The compressor, apparently due to corrosion (oxidation of the metal in contact with moisture).

Due to a series of failures in helicopters of the same type recently, Air Force Commander Maj. Gen. Amikam Nurkin decided to ground the entire helicopter array from training and transport until further notice. In the last two months in the Owl Helicopters array, the last of which was discovered on Sunday this week, during tests performed on the helicopter, while it was on the ground.

Air Force officials told Walla! NEWS that equipment crew officers who inspected the helicopter focused the mechanics' attention on the squadron in the engine. "It is estimated that the source of the faults begins with the control and regulation of the air and fuel in the engine," the sources said. "Now they will be sent for a very in-depth inspection, to see if it is a defective series of parts or problematic maintenance and unexpected wear and tear."

Sources claimed that the crew appointed to inspect the helicopter parts and the faults mentioned, should also check the proximity of the aircraft to the sea. This is due to the location of the squadron at the Palmachim base on the coast. In the past, the squadron was stationed at the base of yards in completely different weather conditions, and the corps suspects that this is what led to the engine wear out.

"Proximity to the sea accelerates corrosion processes in helicopters," explained one source. He added that "grounding the owl array is a drama in the Air Force. It is a workhorse. The veteran stormtrooper cannot replace him in any mission."

Lockheed Martin, the maker of Blackhawk helicopters, said: "Safety is our top priority, and we have offered our help to the Israeli Air Force in this regard. Blackhawk helicopters have been designed and manufactured to meet the toughest flight conditions and stringent operational and safety requirements of the Air Force. Cumulative flight hours around the world, Blackhawk helicopters are the world's proven and best platform for multi-purpose assault helicopters around the world. "

The array of owl helicopters, defined as assault helicopters, performs transport missions of VIPs, but its core mission is to rescue air crews and fighters from enemy territory or complex areas, evacuate wounded from enemy territory or civilians and seriously wounded, and mobilize fighters for operations, with special operations. , In which secrecy is a necessary part of the mission.
