On 1 July, 2010 the flight crew carried out a commercial flight from EPWA (Warszawa-Okęcie) to LSZH (Zürich). The flight was carried out on behalf of Swiss International Air Lines as flight LX1343. There were 84 passengers and 4 crew members on the board. The flight crew carried out the Soxer 1G departure from runway 29 and in accordance with the received clearance were climbing to FL 240. During the climb the flight crew could hear an impact sound from the nose bottom part of the fuselage and at the same time they noticed a malfunction of the Captain’s (CPT) air speed indicator (speed fluctuations +/-20 kt). Flight crew stopped climbing and reported their intention to return to the take off aerodrome. The aircraft was vectored by Approach to land on runway 33. During final approach the windshear warning was triggered. The flight crew performed a Go Around procedure followed by landing.

During the investigation SCAAI determined that the probable cause of the serious incident could be:
Reduced strength of the radome sandwich structure caused by gradual (over time) degradation of the material in fiberglass epoxy composite structures and their bonds.
Probable factor contributing to the incident could be:
- several bird strikes against the radome, which occurred earlier and could cause a progressive weakening of its structure. Maintenance of the radome and minor repairs made by the airplane user did not reveal weakening of the construction and did not maintain properly the composite structure and protect it from environmental factors despite they were carried out according to the procedures given in the aircraft maintenance manual.
