The Lease, the Register and the Missing Export Certificate

A Brunei operator proposes to acquire a used twin-engine aeroplane from a seller in another state and place it on the Brunei register. The seller offers a bill of sale, an export certificate of airworthiness from the exporting state, and a maintenance history with a gap of 14 months. The aircraft's last annual inspection was 13 months ago. The seller is willing to reduce the price if the operator accepts the aircraft "as inspected" and handles registration itself. The operator's lender requires the aircraft to be on the Brunei register and to have a valid Brunei certificate of airworthiness before drawdown, which is in 21 days.

1. Set out the steps and the risks in placing this aircraft on the Brunei register and obtaining a certificate of airworthiness within 21 days.

Registration. Registration requires evidence of ownership and of the aircraft's eligibility. The bill of sale must be examined for a clean chain of title, and any registered interests - mortgages, liens - must be identified, since the lender will require its interest to be recorded. The aircraft must not be on another state's register simultaneously; a deregistration or export certificate of airworthiness from the exporting state is the usual evidence of this. The operator should confirm the exact documentary requirements with the Brunei registry before submitting.

Airworthiness. An export certificate of airworthiness from the exporting state is a statement by that state, not by Brunei. The Brunei authority must be satisfied the aircraft meets the applicable airworthiness requirements, which normally means an inspection and certification process, not automatic acceptance. The 14-month gap in the maintenance history and the 13-month-old annual inspection are red flags: the aircraft has not been maintained in accordance with a recognised programme for over a year, and the gap may conceal unrecorded damage or overdue directives. Airworthiness directives and service bulletins must be reviewed for compliance status.

The 21-day constraint. Realistically, 21 days is tight. The correct approach is to start the authority's process immediately, commission a pre-purchase inspection by an approved organisation, and tell the lender that drawdown may need to be conditional on the C of A being issued. Accepting the aircraft "as inspected" transfers all the airworthiness risk to the operator and does not reduce the authority's requirements.

2. The lender asks what happens if the C of A is not issued by drawdown. Advise the operator on the options and their legal consequences.

The operator has three realistic options, and each has consequences.

1. Delay drawdown. The cleanest option. The lender's condition is a valid Brunei C of A; if it is not issued, the condition is not met and drawdown should be deferred. The commercial cost is to the operator's cash flow and possibly to the seller, who may claim under the sale contract. The operator should check whether the sale contract makes drawdown or C of A issuance a condition precedent.

2. Take delivery and register, but do not fly commercially. Registration and airworthiness certification are separate. The aircraft can be registered while the C of A process continues, but it must not be operated for commercial air transport without a valid C of A. The lender may accept this if its security is the registered aircraft rather than immediate operation.

3. Proceed on the seller's assurances. This is the option to avoid. Accepting the aircraft on the strength of a foreign export certificate and an incomplete maintenance history, and operating before the Brunei C of A is issued, would breach the airworthiness requirements and would likely void the operator's insurance. It would also expose the operator to enforcement action.

The operator should also consider whether the 14-month maintenance gap triggers a requirement for a full inspection or a return to a maintenance programme before certification, and should budget time and cost for that.
