|--------|----|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | b) | [***]                   the                  Aircraft was not operated or maintained in accordance with the                  Technical                  Data listed in Attachment A of Annex A-1 and the manufacturer’s                  documentation furnished to Buyer (including Service Bulletins and                  airworthiness directives) [***] |
|--------|----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | c) | [***]                   the                  Aircraft was not operated under normal airline use [***] |

|-----|-------------------------------|

|   | Normal                  wear and tear and the need for regular maintenance and overhaul                  shall not                  constitute a Defect or failure under this warranty. |
|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 1.10 | Overhaul                  of Warranty Parts |
|------|---------------------------------------------|

|   | Bombardier’s                  liability for a Bombardier Part which has a Defect and is overhauled                  by                  Buyer within the Warranty Period shall be limited only to that                  portion of                  the labour and material replacement related to the Defect. |
|--------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 1.11 | No                  Fault Found |
|------|---------------------------------|

|   | In                  the event that a Bombardier Part returned under a warranty claim                  is                  subsequently established to be serviceable then Bombardier shall                  be                  entitled to charge and recover from Buyer any reasonable costs                  incurred by                  Bombardier in connection with such warranty claim. Providing, however,                  in                  the event that repetitive in-service failure occurs on the particular                  Bombardier Part which is subsequently identified by Bombardier                  on a                  repeated basis to be “no fault found”, then Bombardier and Buyer shall                  discuss and mutually agree a course of further action to help identify                  the                  problem.  In the event the fault is ultimately confirmed to be a                  legitimate warranty claim then the above mentioned costs incurred                  by                  Bombardier and charged to Buyer shall be waived or, if already                  paid,                  refunded to Buyer. |
