Sabena Technics SA v Singapore Airlines Ltd.

A statement of existing fact may constitute a collateral warranty where, objectively assessed in its contractual setting, the parties intended its truth to be enforceable. The assessment considers the totality of the circumstances, including the representor’s knowledge, the representee’s ability to verify the statement, its importance to the transaction and the language used.

Where an ETOPS service bulletin requires modification at the next specified maintenance event and by a later end date, the earlier event may operate as a mandatory time limit. An aircraft subject to the event but not modified cannot be operated on ETOPS routes without prior regulatory consent. A party may recover the reasonable cost of remedial work despite its maintenance contractor having performed it, where the claim represents genuine compensation rather than an uncovenanted profit.

Sabena Technics SA claimed as assignee of Middle East Airlines Airliban SAL’s rights against Singapore Airlines Ltd. The claim arose from a letter issued during negotiations concerning the delivery and maintenance of three Airbus aircraft. Singapore Airlines confirmed that the aircraft complied with the applicable 120-minute ETOPS requirements.

Four engines had undergone the relevant high-pressure turbine module exposure but had not incorporated Service Bulletin 72-382. The issues were whether the letter created an enforceable warranty, whether its statements were accurate, whether alternative misrepresentation claims succeeded, and whether the cost of remedial work was recoverable despite Sabena’s maintenance obligations.

1. Construction of the ETOPS requirement. The words requiring incorporation at the next high-pressure turbine module exposure, but no later than 31 December 1999, identified two points in time. The earlier maintenance event was an effective time limit. An engine exposed to that event after the relevant CMP revision, but not modified and not referred to the aviation authority for permission to derogate, could not subsequently be operated on ETOPS routes without prior consent. [52]-[55]
2. Contractual effect of the letter. The correct question was whether, in all the circumstances, the statement would be understood by a reasonable representee in the actual position of the representee as intended to be contractually enforceable. Singapore Airlines had exclusive knowledge of the modifications, knew that the statement would be relied upon, and supplied the letter as part of the negotiated solution to the delivery dispute. The totality of the circumstances established a collateral warranty as to the truth of the ETOPS statements. [70]-[75]; [82]-[88]
3. Article 11 of the Heads of Terms made only the specified articles legally binding on delivery. The obligation to exchange the letter was therefore not itself enforceable under the Heads of Terms. That did not prevent the letter, once supplied and relied upon by acceptance of delivery, from operating as a separate warranty. [76]-[87]
4. The phrase “in compliance with” required timely completion of the modifications. Regulatory permission to defer the work did not retrospectively make the aircraft compliant with the CMP. The four unmodified engines therefore caused Singapore Airlines to breach the warranty. [89]-[104]
5. MEA’s awareness of documents suggesting non-compliance did not defeat the warranty. A representee who performs the bargain may rely on an unwithdrawn contractual promise unless the circumstances showed that it was not intended to be contractually enforceable. The acceptance team relied on the letter and supporting schedule in accepting the third aircraft. [97]; [119]-[127]
6. The alternative claim under section 2(1) of the Misrepresentation Act 1967 failed because Singapore Airlines proved that it honestly held, and had reasonable grounds for holding, its interpretation of the ETOPS requirement. The negligent misrepresentation claim also failed: the reliance on the view expressed by the relevant aviation authority did not fall below the standard expected of a reasonably careful airline. [105]-[114]
7. MEA’s maintenance agreement with Sabena did not eliminate the recoverable loss. Applying both the wider genuine-compensation approach and the narrower Albazero approach, the cost of making the engines compliant was recoverable. The claim represented genuine compensation and not an uncovenanted profit. Judgment was therefore given for the claimant on the warranty claim, with substantial damages recoverable for the cost of incorporating the service bulletin into the four engines. [128]-[144]
