Incident Overview
On 9 September 2016, a Cessna 150 aircraft was conducting a training flight in the Katowice control zone (CTR EPKM). The crew consisted of a student pilot and an instructor. The flight was part of task C14, which involves training flights along routes using radio navigation aids. The flight was conducted under VFR rules in accordance with the filed flight plan, with two-way communication between the aircraft and the Katowice airport control tower (TWR EPKT).
Sequence of Events
The controller of TWR EPKT issued clearance for a training approach to runway 09 with the intention of performing a touch-and-go landing. Shortly after, communication between the aircraft and the tower was interrupted. The pilot's readback was not received by the tower. In response, the instructor decided to abort the approach and directed the aircraft to point X, then to point G, as specified in the flight plan. After leaving the Katowice control zone, the aircraft landed at the departure airport, EPKM. The crew contacted TWR EPKT via telephone to report the failure of the onboard radio and their return to the departure airport.
Consequences
The incident did not disrupt air traffic and had no impact on flight safety. No injuries were reported; both occupants were uninjured.
Investigation Findings
The investigation, conducted by the operator, determined that the cause of the communication loss was a blown fuse. No recommendations were issued as a result of the investigation.
