Ong Siqi, 22, a salesperson at JD Works, a supplier of commercial equipment including solar panels, was sentenced in a Singapore court on 16 September 2026 to 12 months’ probation and 50 hours of community service. Her parents had to post a 5,000-Singapore-dollar bond for her good behaviour. She faced 31 charges under the Air Navigation Act, pleaded guilty to four, and had the rest taken into consideration. The aircraft was a DJI Mini 2 Pro of about 249 grams, bought in the company director’s name and released to staff for recreation if they followed the rules. Between 13 March and 10 July 2025 she flew it for work on ten occasions without the licences and permits commercial use requires. One charge sheet places her near Jalan Demak off Upper Changi Road East on the morning of 10 July, surveying a roof for a customer interested in the firm’s solar products. Another flight, on 26 August, lasted about two minutes near MacPherson Road, inside five kilometres of Paya Lebar Air Base, without a Class 2 activity permit. The director, the court record says, did not know the drone had left recreation. That fact did not move the offence. The purpose of the flight did.
Singapore’s Civil Aviation Authority splits unmanned aircraft use into recreation, education and business. Registration is required when the aircraft weighs more than 250 grams. That line is why Mini-class airframes are marketed as light enough to skip a label. It is not a licence to sell a survey. For business flying outdoors, CAAS requires an Unmanned Aircraft Pilot Licence regardless of weight, an Operator Permit for the person or firm, and a Class 1 Activity Permit for the job. Recreational flying near an aerodrome or above 200 feet still needs a Class 2 permit. Failure to hold a pilot licence can draw a first-offence fine of up to 50,000 dollars or two years’ jail, or both. The 249-gram airframe therefore saved Ong a registration sticker. It did not save her a pilot licence, an operator permit or an activity permit the moment the flight became a customer roof survey. Location added a second trap. Five kilometres from a military airbase is not a park. Altitude, airspace class and proximity to people sit on the same form. Hobby language on a company Telegram chat does not rewrite the purpose.
India’s Digital Sky and Drone Rules 2021 use a similar 250-gram cut, and the same misunderstanding travels with the Mini. Nano aircraft at or below 250 grams need no Unique Identification Number and no remote-pilot certificate for recreational flight in a green zone at low height, commonly described as 15 metres or 50 feet. That exemption is why a tourist or a student treats the class as unregulated. Commercial use is a different column. A paid inspection, a real-estate video, a solar survey or monetised footage is operator work. Micro and heavier classes already demand a UIN. Commercial work across classes pulls in a remote-pilot certificate from an authorised organisation and, for organised firms, an operator permit, insurance and zone permissions through Digital Sky or the later eGCA workflows. Flying a Nano in a red or yellow zone, over a gathering, or near an airport is not free because the scale read 249 grams. India’s public-education gap is the same sentence Singapore has now prosecuted. Under 250 grams changes registration. It does not erase purpose, place or height.
The useful warning for Indian and other Asian operators is therefore not that Singapore is harsh. It is that a sales pitch built around 'no registration under 250 grams' is incomplete. A firm that leaves a Mini in a cupboard 'for staff recreation' has already created the fact pattern in this case. The first commercial sortie needs a named pilot with a licence, an operator permit, an activity permit, insurance and a logged site. A parent’s bond and a curfew are a young-offender sentence, not a template for a company. A company that repeats the same ten flights would meet the fine and jail table, not probation. Weight is one field on the form. Purpose, location, altitude, airspace, people, airports, registration, qualifications and permits are the rest. The 249-gram drone was legal to own. The commercial flight was not.
