7. Work deadlines

7.1     Any deadlines are binding only if it has been expressly confirmed in writing as such by AES.

7.2     Observance of such binding deadlines shall be subject to the Customer having previously met all contractual obligations, in particular the due and timely delivery of the object of order including keys, aircraft papers, etc., any permits, approvals and clarifications, the settlement of technical questions, the remittance of advance payments demanded by AES and the prompt fulfilment of the Customer’s all other duties under the contract. If this is not the case, appropriate deadline postponements shall be specified or work stoppage may occur. 

Deadlines shall also be postponed if compliance with defined deadline is not possible because of force majeure or unforeseeable events.  AES shall not be liable to Customer for any failure to meet its obligations due to any cause beyond AES’s reasonable control and not occasioned by its fault or negligence (an “Excusable Delay”). Excusable Delay events may include but are not limited to: (i) delays or refusals to grant an export license or the suspension or revocation thereof; (ii) any other acts of any government that would limit the ability for contract performance; (iii) fires, earthquakes, floods, severe weather conditions, or any other acts of God; (iv) epidemic, quarantines or regional medical crisis;(v) labor strikes or lockouts; (vi) riots, strife, insurrection, civil disobedience, armed conflict, terrorism or war, declared or not (or impending threat of any of the foregoing, if such threat might be reasonably be expected to cause injury to people or property); and (vii) shortages or inability to obtain materials or components. If an Excusable Delay event causes AES delay, then the date of AES’s performance will be extended by the period of such delay.

7.3     In the event of a slot and/or work scope cancellation by the Customer, Customer shall be liable to pay to AES a cancellation fee equal to 5% of the total amount quoted for the project within 10 (ten) days of the cancellation notice. In addition, AES reserves the right to invoice and Customer agrees to pay for any restock charges incurred and any materials and components ordered to support the project, as well as labour, planning or any other direct costs related to project preparation. For the sake of clarity, if materials or components cannot be returned to their respective vendor(s), Customer will be billed in full for these items. 

7.4     The same applies in case that the aircraft replacement parts and ground support equipment or parts have to be delivered by a third party for the work and the party is delayed and purchase of the parts from a different source is not reasonably possible.

7.5     In case such extended deadline is not met for reasons which AES is responsible for, the Customer shall have the right to withdraw from the contract by written statement after paying full compensation for the work already performed by AES. The Customer shall have a claim for damages only in cases where the Customer’s losses, damages or expenses result directly from the wilful misconduct or gross negligence of AES.

8. Exchange and loaned parts


8.1     Exchange basis: If the Customer is supplied with exchange parts, he shall return the off-core parts to AES within 10 days of the receipt of such exchange parts. The costs of exchange shall be determined in advance by the manufacturer of the parts or by AES. If the expense of repairing the returned off-core parts exceeds the cost of the exchange, the Customer shall be charged with the difference. If for any reason whatsoever the Customer returns a part remitted to him by AES without having used it, such part shall only be accepted if serviceable upon arrival at AES. The Customer shall in addition be charged with a restocking and certification fee of 15% of the part's current list price or such charges that a supplier or OEM applies and invoices to AES, whichever is higher. If a returned part is found to be defective, the Customer shall be charged with the cost of repairing and recertification. If the part is not repairable, the Customer shall be debited with the full sales price.

8.2     Loan basis: The provisions of AES standard loan agreement shall be applicable to loaned parts even in cases in which no such agreement is specifically concluded. Loaned parts shall be returned serviceable in any event. If such is not the case, the repair and recertification costs or, if repairs are not cost-effective, the replacement cost of loaned parts shall be charged to the Customer.

9. Delivery, redelivery and acceptance


9.1     The Customer shall deliver at its own expenses the part or equipment to be repaired or maintained (“Subject of Order”) DDP (Incoterms 2010) AES facility where such repair or maintenance shall take place.

9.3     Acceptance of the Subject of Order will be approved in writing or earlier if the Customer utilizes it. Acceptance will be at the expense of the Customer. Acceptance is not permitted to be refused for flaws that do not interfere with the airworthiness or significantly interfere with the functional capability of the Subject of Order. 

9.4     Once AES has given the Customer written notice of completion of a repair or maintenance job, the Customer will pick up the Subject of Order and inspect the services within a period of no more than 3 working days from the date of notice, after which period the Customer will be in default and deemed to have accepted the Subject of Order and the aircraft parts will be entirely at his risk, and AES will only remain liable thereafter for destruction/damage to the parts arising directly from the wilful misconduct of AES.

9.5     In case the other Subject of Order remains at AES because (i)formal redelivery and/or acceptance has not occurred due to work stoppage by AES or (ii) the contract is terminated by either party , or (iii)  acceptance deadline as stated in 9.4 has lapsed, and in consequence the aircraft remains grounded then it will be the sole responsibility of the Customer to define and formally order to  AES any preventive or preservative maintenance measures to be applied to the parts during such extended grounding period of the aircraft to ensure continuing airworthiness and fitness for use of the component. AES hereby expressively excludes any liability for dilapidation of the aircraft component during any prolonged grounding period. The aircraft or Subject of Order will be entirely at Customer’s risk, and AES will only be liable for destruction/damage to the aircraft part arising directly from the wilful misconduct of AES.

9.6     In case Customer fails to advise on performance of maintenance measures per article 9.5, or if Customer does not respond to AES request on such measures and if AES in its reasonable judgement concludes that certain preventive maintenance actions would be advisable, Customer agrees that AES has the right, but not the obligation, to define and perform such actions. Customer will remain fully responsible for the cost of such actions.

10.2 Any resale by the Customer of Goods in which title has not passed to the Customer shall (as between

AES and the Customer only) be made by the Customer as agent for AES and the Customer shall be deemed to be holding any monies received from the resale of such Goods on trust for AES.

10.3 AES’s employees and agents shall be entitled to enter any land, buildings, vehicles or aircraft where the Goods or part of them are situated or are reasonably thought to be situated, and may take possession of them at any time, to the extent permissible under the Applicable Law.

11.  Right of lien


          In respect of all claims, whether due or not, resulting from contractual relations with its Customers, including claims resulting from prior business relations with the Customer concerned, AES shall have, in addition to its legal right of retention, a contractual right of lien on such objects in its possession, independently of the Customer’s proprietary rights. The Customer herewith gives its consent and approval to all measures reasonably taken by AES to secure its right of lien. The Customer agrees that AES has the right to retain the aircraft and / or to enforce such right of lien for the purpose of securing any of its claims against the Customer, including claims resulting from (i) prior business relations with the Customer concerned, and/or (ii) a business relationship between the Customer and any affiliate which is under the same ultimate control as AES.
