Executive summary
Myanmar Witness has documented evidence suggesting that Czech Let Aircraft Industries, part of Omnipol, may have supplied the Myanmar Air Force (MAF) with three Let L410 UNVP-E20 aircraft.
According to tracking data, Let Aircraft Industries owned Let L410-UVP E20 Turbolet serial number 3413, registered in the Czech Republic as OK-JMA, flew from Kunovice Airport to the Yangon area in late September 2024. Then, two additional aircraft, OK-AMJ (serial number 3418) and OK-AMK (serial number 3419), followed a similar journey the following year. Tracking data recorded OK-AMJ (serial number 3418) departing on 9 June 2025, and OK-AMK (serial number 3419) leaving Kunovice airport on 8 July 2025.
As of 24 October 2024, tracking data from FlightRadar24 indicates that the Myanmar authorities have registered the OK-JMA (3413) aircraft as XY-AMV, and it has since belonged to the MAF. This aircraft has since been tracked flying across various locations in Myanmar.
However, at the time of writing, Myanmar Witness is unable to independently confirm the continuous presence of the other two aircraft (OK-AMJ and OK-AMK) since their arrival in Myanmar.
Myanmar Witness, however, has grounds to believe that the OK-AMJ and OK-AMK aircraft that flew in 2025 might now be with the MAF.
If a Czech Republic company has sold its aircraft to the MAF, this could be a violation of the EU sanctions against Myanmar. It is worth noting that Let Aircraft Industries also delivered two previous L-410 UVP-E20 (serial numbers 3411 and 3412) to Kazakhstan in December 2023 in a similar manner.
This investigation examines flight tracking data and satellite imagery concerning a single Let L410-UVP E20 Turbolet aircraft, identified by its unique serial number 3413. The records show the aircraft was first registered as OK-JMA and later re-registered as XY-AMV in Myanmar, strongly indicating that both registrations correspond to the same aircraft. The unchanging serial number further supports that these observations relate to one and the same plane.
While further confirmation is required, the convergence of tracking data and callsign use supports the hypothesis that the MAF could own three Let L410 UVP-E20 aircraft.
