SES - Power to fly now

SES Products

At SES we remain committed to growing our pool of CFM56 engines in order to provide comprehensive customer support through a variety of flexible engine lease services. We currently offer a wide range of CFM56 engine lease options:

Short Term Lease

The most basic option, but also one of the most unique, is the 'ad hoc short-term lease'. SES offers customers a genuine short-term lease product whereby no minimum lease term applies. You pay for the number of days you need and redeliver when finished, no hidden costs or extras built in. This product is structured on a daily charge basis whereby the customer is billed for the days used. To reduce lease time and hence costs for an airline, SES does not typically request a test cell run at end of a short term lease provided that the engine has had a regular operation and demonstrates normal performance deterioration at redelivery.

Operating Lease

A more common product which generally runs over a longer term 3+ years. There is an agreed Delivery and redelivery Condition and the lease term is fixed. The airline pays for the engine regardless of whether it is installed and typically takes maintenance responsibility during the lease term. Operating Leases are an effective solution where expected utilisation is high over a given period and where an airline is not in a position to purchase its own spares.

Engine Sales & Exchange

SES can offer its customers a wide range of CFM56 assets for sale at any given time. In addition we can offer an engine exchange programme whereby an asset owner/operator may elect to swap out its unserviceable or older generation CFM56 engines with similar asset types that have greater on-wing life remaining. With a large portfolio of CFM56 engines to select from, SES can tailor a number of sale & exchange packages to suit specific customer requirements.

Guaranteed Availability

This service is unique to SES and more commonly known as "GAF". It is an insurance type product devised to protect airlines against the risk of an AOG. An annual access fee, calculated using the technical details of the supported fleet, provides the airline with guaranteed availability of one or more engines at pre-agreed terms and conditions. Engines are made available for lease within 24 hours of request.
