Evaluation Framework for Grounding and Review of Aircraft Operating in Singapore

Mr Desmond Choo asked the Minister for Transport (a) what is the Ministry's evaluation framework and process in deciding whether to ground a particular model of aircraft; and (b) how are aircraft types regularly reviewed before they are allowed to operate in Singapore.

The Civil Aviation Authority of Singapore (CAAS) evaluates an aircraft type for operation to Singapore based on an established framework that is in accordance with international regulations and processes. It includes assessments of the aircraft design, the maturity of the technologies used, and the resolution of all known safety issues with the aircraft. The evaluation is carried out by a multi-disciplinary team of CAAS officers, including engineers and officers with pilot qualifications.

After an aircraft is approved for operation to Singapore, CAAS continues to review the reliability and airworthiness of in-service aircraft through regular inspections, monitoring of technical defects and incidents, and review of safety information provided by aircraft manufacturers, airline operators and counterpart regulatory authorities.

CAAS will ground an aircraft type if it determines that the continued operation of the aircraft presents a safety risk.
