Tuninter Airlines' safety record is primarily marked by one significant and fatal incident: Tuninter Flight 1153 on August 6, 2005. The ATR 72-202 aircraft, registered as TS-LBB, ditched into the Mediterranean Sea approximately 18 miles (29 km) from Palermo, Italy, resulting in 16 fatalities out of 39 people on board. This was the first fatal accident in the company's 14-year history.

The accident was caused by fuel exhaustion, which occurred due to the inadvertent installation of a fuel quantity indicator (FQI) designed for a smaller ATR 42 aircraft into the larger ATR 72. This led ground crews and the flight engineer to load an inadequate amount of fuel, as the incorrect gauge showed an ample supply even after all usable fuel was consumed. The investigation highlighted several contributing factors, including errors by ground mechanics, errors by the flight crew in not adhering to operational procedures, inadequate checks by the airline regarding crew compliance, inaccuracies in the aircraft management and spares information system, and unsatisfactory maintenance and organizational standards of the operator. It also pointed to a lack of an adequate quality assurance system and insufficient surveillance by the competent Tunisian authority.

Following the 2005 crash, the Italian government banned Tuninter from flying into Italian airspace. There is no information available regarding specific regulatory certifications like IOSA or FAA compliance for Tuninter Airlines prior to its rebranding. The accident aircraft was 14 years old at the time of the incident. Overall, Tuninter's safety assessment is heavily influenced by the 2005 accident, which exposed critical failures in maintenance protocols, operational procedures, and regulatory oversight within the airline. No safety awards or recognitions for Tuninter Airlines were found.
