Except for the specific purposes of this Clause 18.1.2, the term “BFE Supplier” will be deemed to include Approved
BFE Suppliers. 
  

	 18.1.3
	 The Seller will advise the Buyer of the dates by which, in the planned release of engineering for the

The BFE Engineering Definition will include the description of the dimensions and weight of BFE, the information related to
its certification and the information necessary for the installation and operation thereof, including when applicable 3D models compatible with the Seller’s systems. The Buyer will furnish, or cause the BFE Suppliers to furnish, the BFE
Engineering Definition by the dates advised by the Seller pursuant to the preceding paragraph after which the BFE Engineering Definition will not be revised, except through an SCN executed in accordance with Clause 2. 

 

	 18.1.4
	 The Seller will also provide in due time to the Buyer a schedule of dates and the shipping addresses for
delivery of the BFE and, where reasonably requested by the Seller, additional spare BFE to permit installation in the Aircraft in a timely manner. The Buyer will provide, or cause the BFE Suppliers to provide, the BFE by such dates in a serviceable
condition. The Buyer will, upon the Seller’s request, provide to the Seller dates and references of all BFE purchase orders placed by the Buyer.

including but not limited to those set forth in the Customization Milestone Chart; 


  

	 	 (ii)
	 that, should a timeframe, quality or other type of risk be identified at a given BFE Supplier, the Buyer
will allocate resources to such BFE Supplier so as not to jeopardize the industrial schedule of the Aircraft; 


  

	 	 (iii)
	 for major BFE, including, but not being limited to, seats, galleys and IFE (“Major BFE”) to
participate on a mandatory basis in the specific meetings that take place between BFE Supplier selection and BFE delivery, namely:

	 Preliminary Design Review (“PDR”), 



 

	 	 (b)
	 Critical Design Review (“CDR”); 



 

	 	 (iv)
	 to attend the First Article Inspection (“FAI”) for the first shipset of all Major BFE.
Should the Buyer not attend such FAI, the Buyer will delegate the FAI to the BFE Supplier thereof and confirmation thereof will be supplied to the Seller in writing; 



 

	 	 (v)
	 to attend the Source Inspection (“SI”) that takes place at the BFE Supplier’s premises
prior to shipping, for each shipset of all Major BFE. Should the Buyer not attend such SI, the Buyer will delegate the SI to the BFE Supplier and confirmation thereof will be supplied to the Seller in writing. Should the Buyer not attend the SI, the
Buyer will be deemed to have accepted the conclusions of the BFE Supplier with respect to such SI. 


 The
Seller will be entitled to attend the PDR, the CDR and the FAI. In doing so, the Seller’s employees will be acting in an advisory capacity only and at no time will they be deemed to be acting as Buyer’s employees or agents, either directly
or indirectly.
