Factual and Procedural Background
This action concerns the lease of a Boeing 737-300 aircraft for five years by its owners, Company A, to Defendant, a national airline now in liquidation. The aircraft was redelivered to Company A by a prior lessee and subsequently delivered to Defendant in Singapore on 19 August 2008, entering commercial service shortly thereafter. On 6 September 2008, a defect was discovered during a pre-flight inspection in The City, leading to the suspension of the aircraft's airworthiness certificate by the national aviation authority. The aircraft was sent to a maintenance facility in France for repairs, which took longer than expected, and the airworthiness certificate was not restored. Defendant ceased trading in October 2009 and entered liquidation. Company A served termination and redelivery notices in March 2010, and the aircraft was redelivered in November 2010. Subsequently, Company A leased the aircraft to another operator in 2011 after the aircraft was certified airworthy by the Federal Aviation Authority in the United States.
Company A claims unpaid rent and maintenance reserves totaling approximately US$4.6 million up to November 2010, plus damages for loss of rent until the end of the lease term, alternatively for conversion, amounting to about US$6.9 million, less amounts received from the subsequent lessee and mitigation costs. Defendant counterclaims damages for breach of contract by Company A in failing to deliver the aircraft in the contractual condition, specifically alleging non-airworthiness, seeking damages of approximately Euros 6.8 million for costs of substitute aircraft and attempts to restore airworthiness.
Legal Issues Presented
- Whether the aircraft was delivered in the condition required by the lease, in particular whether it was airworthy on delivery.
- The legal effect of the Certificate of Acceptance signed by Defendant, including whether it constitutes conclusive proof or estoppel regarding the condition of the aircraft on delivery.
- Whether Defendant is estopped from alleging breach of the delivery condition due to its representation in the Certificate of Acceptance.
- Whether Defendant is liable to pay rent and maintenance reserves despite alleged defects.
- Whether there was a total failure of consideration entitling Defendant to recover payments made.
- Whether the lease was frustrated by the suspension or refusal to reinstate the airworthiness certificate.
Arguments of the Parties
Company A's Arguments
- The aircraft was delivered and accepted by Defendant in accordance with the lease terms, including airworthiness.
- If the aircraft was not airworthy, Defendant is estopped by the Certificate of Acceptance or by law from asserting non-compliance.
- Defendant's failure to pay rent and maintenance reserves constitutes repudiatory breach of the lease.
- The Certificate of Acceptance signed by Defendant is conclusive proof of acceptance and satisfaction with the aircraft condition, precluding claims for breach.
- The lease terms impose absolute obligations on Defendant irrespective of events such as suspension of airworthiness certificate, negating frustration claims.
Defendant's Arguments
- The aircraft was not delivered in the condition required by the lease, specifically it was not airworthy.
- The Certificate of Acceptance does not preclude Defendant from claiming non-compliance with delivery conditions and Defendant is not estopped.
- Defendant was never obliged to pay rent or maintenance reserves due to breach and alternatively is entitled to recover any payments on grounds of total failure of consideration.
- The lease was frustrated by the suspension and non-renewal of the airworthiness certificate, discharging Defendant's obligations.

Court's Reasoning and Analysis
The court carefully examined the factual background and the contractual terms, focusing on the condition of the aircraft on delivery and the legal effect of the Certificate of Acceptance. It found that the aircraft was not airworthy on delivery due to corrosion and defects in flight control cables, pulleys, fuselage damage, and contamination in fuel tanks, among others. However, the court held that the Defendant was estopped from alleging breach of the delivery condition because it had irrevocably and unconditionally accepted the aircraft in the Certificate of Acceptance, which contained a clear, unambiguous, and unequivocal representation that the aircraft complied with the delivery condition under the lease.
The court distinguished the estoppel in this case from that in Lowe v Lombank, emphasizing the commercial context, the prior inspections by Defendant’s maintenance organization, and the reliance by Company A on Defendant’s representation. It found that the estoppel prevented Defendant from pursuing its claim for damages for breach of delivery condition.
On the question of rent liability, the court held that Defendant’s obligation to pay rent and maintenance reserves was triggered by acceptance and was not negated by alleged non-compliance, due to estoppel.
The court considered Defendant’s alternative claims for total failure of consideration and frustration. It found no total failure of consideration because Defendant had possession and was estopped from denying delivery condition compliance. The frustration claim was rejected because the lease expressly allocated the risk of suspension or loss of airworthiness certificate to Defendant, who had absolute obligations irrespective of contingencies. The events did not render Defendant’s obligations radically different from those originally undertaken.
Regarding damages, the court found that the breach by Company A caused the aircraft to be sent to the French maintenance facility and that some costs incurred there were recoverable. However, some costs would have been incurred anyway during the lease term. The court also found that certain defects and failures to comply with maintenance directives were not attributable to Company A but to the previous lessee. The court rejected claims for certain costs such as insurance after termination and deposits related to other aircraft.
Overall, the court’s reasoning balanced the contractual allocations of risk, the factual findings on aircraft condition, and the legal effects of contractual representations and estoppel.
Holding and Implications
The court held in favor of Company A and against Defendant. Company A is entitled to judgment on its claim for unpaid rent, maintenance reserves, and damages for repudiatory breach of lease by Defendant. Defendant’s counterclaim for damages for breach of delivery condition is dismissed due to estoppel arising from the Certificate of Acceptance.
The direct effect is that Defendant must pay amounts owed under the lease and cannot challenge the delivery condition of the aircraft. No new precedent was established beyond the application of established principles of estoppel, contractual interpretation, and frustration in the context of aircraft leasing. The case underscores the importance of formal acceptance documents and the allocation of risk in commercial aircraft leases.
