1969 Yukhnov mid-air collision

Template:Unreliable sources Template:Infobox aircraft occurrence The 1969 Yukhnov mid-air collision transpired on 23 June 1969 when an Ilyushin Il-14M operating as Aeroflot Flight 831—a scheduled domestic service from Moscow’s Bykovo Airport to Simferopol International Airport in Crimea—collided mid-flight with a Soviet Air Force Antonov An-12BP above the Yukhnovsky district of Kaluga Oblast within the Russian SFSR of the Soviet Union. Tragically, all 120 individuals aboard both planes lost their lives in this accident.

Aeroflot Flight 831

The aircraft engaged was an Ilyushin Il-14M bearing registration CCCP-52018, assigned to Aeroflot’s Ukrainian division. Prior to the incident, it had accumulated a total of 24,653 flight hours. Onboard Flight 831 were five crew members and nineteen passengers. The flight deck was commanded by Captain Georgy Pavlenko with First Officer Viktor Pavlovich Buyanov serving as copilot.

Soviet Air Force Antonov An-12BP

The Antonov An-12, operated by the Soviet Air Force and identified by callsign 08525, was part of a quartet of aircraft performing tactical flight demonstrations for the Minister of Defense, Andrei Grechko. Among these, two planes were tasked with transporting equipment, while the other two—including the ill-fated An-12—were carrying paratroopers from the 7th Guards Mountain Air Assault Division. All five crew members and 91 paratroopers aboard the aircraft lost their lives in the crash. The cockpit team comprised Major Alexei Ryabtsev, Junior Lieutenant Vladimir Priplov, and Captain Nikolai Mikhailovich Maslyuk.

Crash details

At 13:25, the An-12 with callsign 08525 departed from Kėdainiai Air Base, being the last to take off in a formation of four aircraft. These four An-12s launched at intervals ranging from eight to ten minutes and maintained flight levels between 3,000 and 3,600 m (9,800 and 11,800 ft).

The Ilyushin Il-14 took off from Bykovo Airport at 14:07, ascending to its assigned altitude of 2,700 m (8,900 ft).

At 14:40:55, the Il-14 crew contacted air traffic control requesting clearance to climb to 3,300 m (10,800 ft) to avoid intense turbulence and cumulus cloud formations. Since the An-12 formation was operating at 3,000 m (9,800 ft), controllers proposed that the Il-14 descend to 2,700 m (8,900 ft) instead; however, the Il-14 pilots rejected this suggestion due to concerns about worsening turbulence at lower levels.

At 14:50:17, after passing over Yukhnov, the An-12 crew switched communication to a different controller and confirmed their altitude at 3,000 m (9,800 ft).

The collision occurred over Yukhnov at 14:52. The An-12 was traveling on a heading between 106° and 121° at speeds ranging from 500–529 km/h (311–329 mph; 270–286 kn), while the Il-14 was on a course between 235° and 245°, moving at speeds between 324–360 km/h (201–224 mph; 175–194 kn). Initial contact happened at the wingtips; subsequently, the nose of the An-12 struck the right horizontal stabilizer of the Il-14. This impact caused the An-12 to lose its right wing along with both right-side engines, resulting in an uncontrollable spin toward the ground. The Il-14 sustained damage to part of its right wing and upper fuselage. The An-12 crashed near Vypolzovo village, while the Il-14 came down near Trinity village, with wreckage approximately 3,800 m (12,500 ft) apart. Tragically, all 120 individuals on both aircraft were killed.

Causes

The investigation revealed that the Ilyushin Il-14 pilots disregarded air traffic control directives by climbing to approximately 3,000 m (9,800 ft) in an attempt to evade clouds and turbulence—altitude occupied by the Antonov An-12 formation. The collision took place between 2,910–2,960 m (9,550–9,710 ft), whereas the Il-14 was supposed to maintain an altitude of 2,700 m (8,900 ft). Additionally, it was determined that the An-12 crew contributed to the accident by flying slightly below their assigned flight level of 3,000 m (9,800 ft).

Memorial

Monument dedicated to the fallen servicemen.

The decision to erect a memorial honoring the deceased soldiers was made by Vasily Margelov, Commander of the Airborne Forces and General of the Army. Funds were gathered to finance the creation of a monument commemorating the soldiers who lost their lives, totaling 250 thousand rubles. One year following the tragedy, a memorial was unveiled at the location where the An-12 aircraft went down. Crafted by Yevgeny Vuchetich, the monument features a sculptural group of a paratrooper alongside a kneeling mother, inscribed with the words: Eternal memory to the heroes-paratroopers and pilots. Adjacent to this statue lies a platform displaying 96 marble plaques, each bearing the name of a soldier who perished in the incident.

A separate monument stands at the crash site of the Ilyushin Il-14, paying tribute to both pilots and passengers.
