	2)  Letter Agreement SWA-PA-03729-LA-1106469R1, ***




This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement.  All capitalized terms used but not defined in this Letter Agreement will have the same meaning as in the Purchase Agreement.


1.Service Ready Operational Validation. 


In order to ensure that the Aircraft is ready for entry into service upon delivery, Boeing and Customer will implement a service ready operational validation program (SROV) which will aid in validating the combination of the Aircraft, support products and services as well as Customer’s own preparation for entry into service.  The SROV will use *** to accomplish the validation.




2.    Validation Planning and Execution.


2.1    The SROV Plan will be carried out over the course of five (5) or fewer calendar days and simulate in-service operations. 


2.2    The primary objectives of the SROV include validation in the following areas:(i) normal flight operations, (ii) limited non-normal flight operations, (iii) routine maintenance activities, (iv) select non-routine maintenance activities, (v) airplane connectivity options both on-ground and in-flight utilizing Customer’s IT infrastructure, (vi) typical aircraft operations (e.g. servicing, cargo operations), and (vii) aircraft support products (e.g. flight data, maintenance data, parts data and ground support equipment/tooling).


2.2.1    SROV planning documentation will describe SROV conditions and activities (SROV Plan).  Boeing and Customer will jointly develop the SROV Plan in accordance with the following outline and constraints, to represent in-service operation.

***
















2.2.2    Prior to the start date of the SROV, a Boeing SROV project leader (SROV Project Lead) will be the primary point of contact for communication and coordination between Customer and Boeing relating to the SROV Plan.  After the SROV begins, a Boeing test director (Boeing Test Director) will direct the SROV Plan and will serve as the primary contact for Customer to discuss any matters relating to the SROV.


2.2.3    After the SROV begins, Customer will coordinate with the Boeing Test Director regarding any suggested changes to the SROV Plan or additional validation conditions, examples of which are listed below.  Inclusion of such additional validation conditions will be at the discretion of the Boeing Test Director.  If Boeing desires to make any changes to the SROV Plan, then Boeing will coordinate such changes with Customer’s designated representative.


		
	a)
	Non-routine activities - flaps-15 landing, simulated removal and replacement of an LRU or other “one-off” or contingency scenarios related to normal operations.


		
	b)
	Routine activities with intervals longer than the SROV execution duration - “A-check equivalent” maintenance activity or demonstration of new (i) ground support equipment (GSE) or (ii) maintenance procedures.


		
	c)
	Airline-specific scenarios - passenger-related preparations that depend on aircraft/airlines systems or procedures to be successful. 




3.    Operation of the SROV Aircraft.

3.2    ***














3.3    Customer's Participation in the SROV.


3.3.1    Customer will submit to Boeing a list of personnel who may participate in flight activities as Essential Crew under the conditions of 3.2 above, including a description of each person’s proposed role.


3.3.2    All Customer Essential Crew scheduled to participate in a given validation block will be required to attend a mandatory preflight briefing scheduled by the Boeing Test Director which will be conducted prior to each validation block. 


3.3.3    Customer will assist Boeing with any emergency arrangements or contingency arrangements in the event of incident or damage to the SROV Aircraft or other difficulties.


3.3.4    Customer will appropriately familiarize Boeing personnel with Customer's operations and procedures, at no charge to Boeing (including but not limited to Boeing flight crew and maintenance personnel).


3.4    Maintenance of the SROV Aircraft.


3.4.1    ***


























3.4.2    Records.


Boeing records will be the only official documentation of the SROV Aircraft.

3.4.3    Fuel and Other Goods and Services.


3.4.3.1    Customer and Boeing will work together to ensure that appropriate landing slots, gates and other operational requirements and services are arranged in advance at all airports where the SROV Aircraft will land.  Where Customer's established relationships and on‐site personnel and resources will enable Customer to make more advantageous arrangements, Customer will, upon Boeing request, make necessary arrangements on Boeing's behalf or will assist Boeing in making such arrangements, as appropriate.

5.    Realization of Additional Objectives during SROV.


The primary objectives of the SROV are described in Paragraph 2.1 above.  Other objectives are secondary, and may be pursued when, in Boeing's and Customer’s reasonable judgment, such secondary objective will not: (i) interfere with nor jeopardize the primary objectives, (ii) lengthen the SROV schedule or (iii) ***

6.    Contingencies.


6.1    SROV Aircraft Airworthiness Certification.


Boeing shall make reasonable and timely efforts to obtain an experimental airworthiness certificate or make other arrangements for airworthiness certification of the SROV Aircraft in order to conduct the SROV Plan.  In the event that Boeing is not successful in obtaining the necessary airworthiness certification and cannot make alternate arrangements in support of the SROV Plan, Boeing and Customer will mutually agree to revisions to the SROV Plan to facilitate such airworthiness certification of the SROV Aircraft.  If Boeing and Customer (i) cannot agree on such revisions to the SROV Plan or (ii) Boeing is unable to obtain an airworthiness certification of the SROV Aircraft, then Boeing may cancel any part or all of the SROV.


6.2    Boeing Type Certificate Flight Testing.


Boeing will make every reasonable effort to ensure the SROV Aircraft is no longer required to support 737-8 type certification during the SROV period.  However, in the event that unplanned type certification testing requires use of the SROV Aircraft during the period the parties plan to conduct the SROV, Boeing may (i) cancel the SROV (ii) re-schedule the SROV and/ or (iii) adjust the scope of the SROV Plan as appropriate.
