What happened
On August 22, 2014, an air traffic controller at Warsaw Chopin Airport (EPPW) observed unauthorized aerial activity within the MATZ airspace. The controller identified four ultralight aircraft traveling from a northeasterly direction toward the southwest. This movement intersected the approach path for runway 28L at a distance of approximately 1 nautical mile from the runway threshold.
At the time of the incursion, a PZL M-28 was performing a standard circuit pattern within the same controlled airspace. To ensure safety, the air traffic controller immediately notified the pilot of the PZL M-28 regarding the presence of the unidentified aircraft. The pilot monitored the other aircraft in the vicinity and successfully maintained separation, completing the planned flight maneuvers without further incident.
The investigation
The PKBWL investigation focused on identifying the four ultralight aircraft and determining how they entered the controlled airspace. Despite the efforts of the commission, the identities of the other airspace users involved in the incursion could not be established.
