AIRFRAME AND ***

***

relating to

BOEING MODEL 737-10 AIRCRAFT

For the purposes of this AE2, the term Aircraft shall mean 737-10 Aircraft.

 

1. Formula.

Airframe and *** price adjustments (Airframe Price Adjustment) are used to ***
to be *** in *** at the signing of this Purchase Agreement and to *** to be ***
at *** for the *** of ***. The Airframe Price Adjustment will be *** at the ***
of *** in accordance with the following formula:

***

Where:

*** = ***.

*** = *** plus the *** of the *** (as set forth in Table *** of this Purchase
Agreement).

***

Where:

*** is the *** (as set forth in Table *** of this Purchase Agreement);

*** is a *** determined using the ***, calculated by establishing a ***
arithmetic average *** (expressed as a decimal and rounded to the nearest tenth)
using the *** for the *** of scheduled delivery of the applicable Aircraft. As
the *** values are only released on a *** basis, the value released for the ***
will be used for the ***; the *** released for the *** will be used for the ***;
the *** released for the *** will be used for the ***; the *** released for the
*** will be used for the ***.

***

Where:

*** is the *** (as set forth in Table *** of this Purchase Agreement); and

 

UAL-PA-03776-AE2

BOEING PROPRIETARY

--------------------------------------------------------------------------------

*** is a *** determined using the ***, calculated as a *** arithmetic average of
the released *** (expressed as a decimal and rounded to the nearest tenth) using
the *** for the *** of scheduled delivery of the applicable Aircraft.

As an example, for an Aircraft scheduled to be delivered in the ***, the *** of
the *** will be utilized in determining the value of *** and ***.

Note:

 

  (i) In determining the values of *** and ***, all calculations and resulting
*** will be expressed as a decimal rounded to the nearest ten-thousandth.

 

  (ii) *** is the numeric ratio attributed to *** in the Airframe Price
Adjustment formula.

 

  (iii) *** is the numeric ratio attributed to *** in the Airframe Price
Adjustment formula.

 

  (iv) The *** are the actual average *** reported by ***. The actual average
*** are calculated as a *** arithmetic average of the released *** values
(expressed as a decimal and rounded to the nearest tenth) using the *** for the
*** the airframe base year. The applicable base year and corresponding
denominator is provided by Boeing in Table *** of this Purchase Agreement.

 

  (v) The final value of *** will be rounded to the nearest dollar.

 

  (vi) The *** if it will *** in the ***`.

 

2. Values to be Utilized in the Event of Unavailability.

2.1 If the *** substantially revises the methodology used for the determination
of the values to be used to determine the *** and *** values (in contrast to
benchmark adjustments or other corrections of previously released values), or
for any reason has not released values needed to determine the applicable ***,
the parties will, prior to the *** of any such Aircraft, select a substitute
from other *** or ***. Such substitute will result in the same adjustment,
insofar as possible, as would have been calculated utilizing the original values
adjusted for fluctuation during the applicable time period. However, if within

3 AIRCRAFT CONFIGURATION

 

  3.1 The guarantees contained in this Attachment are based on the Aircraft
configuration as defined in ***, dated ***, plus any changes mutually agreed
upon or otherwise allowed by the Purchase Agreement to be incorporated into the
Customer’s Detail Specification (herein referred to as the Detail
Specification). Appropriate adjustment will be made for changes in such Detail
Specification approved by the Customer and Boeing or otherwise allowed by the
Purchase Agreement which cause changes to the flight performance and/or weight
and balance of the Aircraft. Such adjustment will be accounted for by Boeing in
its evidence of compliance with the guarantees.

 

  3.2 The guarantee payloads of paragraphs 2.5.1, 2.5.2, 2.5.3, and 2.5.4, and
the specified payload in the *** guarantee of paragraph 2.5.5 will be adjusted
by Boeing for the effect of the following on OEW in its evidence of compliance
with the guarantees:

(1) Changes to the Detail Specification or any other changes mutually agreed
upon between the Customer and Boeing or otherwise allowed by the Purchase
Agreement.

(2) The difference between the component weight allowances given in Appendix E
of the Detail Specification and the actual weights.

 

4 GUARANTEE CONDITIONS

 

  4.1 All guaranteed performance data are based on the International Standard
Atmosphere (ISA) and specified variations therefrom; altitudes are pressure
altitudes.

 

  4.2 For the purposes of these 737-10 guarantees the Federal Aviation
Administration (FAA) regulations referred to in this Attachment are, unless
otherwise specified, 14 CFR Part 25 effective February 1, 1965, including
Amendments 25-1 through 25-141 with the exceptions permitted by 14CFR21.101.

  4.3 In the event a change is made to any law, governmental regulation or
requirement, or in the interpretation of any such law, governmental regulation
or requirement that affects the certification basis for the Aircraft as
described in Paragraph 4.2, and as a result thereof, a change is made to the
configuration and/or the performance of the Aircraft in order to obtain
certification, the guarantees set forth in this Attachment will be appropriately
modified to reflect any such change.

 

  4.4 The takeoff and landing guarantees, and the takeoff portion of the mission
guarantees are based on hard surface, level and dry runways with no wind or
obstacles, no clearway or stopway, *** mph tires, with *** brakes, anti-skid
operative, alternate go-around flap procedure (option to select Flaps 5 when
performing a return to land check), and with the Aircraft center of gravity at
the most forward limit unless otherwise specified. If the guarantee condition
specifies an alternate forward center of gravity, the performance will reflect
the more aft center of gravity of the alternate forward center of gravity
specified in the guarantee condition or the forward center of gravity limit. The
takeoff performance is based on no engine bleed for air conditioning or thermal
anti-icing and ***. The Power Management Control (PMC) is turned on. Unbalanced
field length calculations and the improved climb performance procedure will be
used for takeoff as required. The landing performance is based on the use of
automatic spoilers.

 

  4.5 The enroute one-engine-inoperative altitude guarantee is based on engine
bleed for air conditioning with one pack operating. No engine bleed for thermal
anti-icing is provided unless otherwise specified. ***.

 

  4.6 The altitude capability guarantee and the climb, cruise and descent
portions of the mission guarantees includes allowances for normal power
extraction and engine bleed for normal operation of the air conditioning system.
The digital bleed is set for the Customer interior in Paragraph 2.5.7. No bleed
or power extraction for thermal anti-icing is provided unless otherwise
specified. ***.

 

  4.7 The altitude capability guarantee and the climb, cruise and descent
portions of the mission guarantees is based on an Aircraft center of gravity
location, as determined by Boeing, not to be aft of *** percent of the mean
aerodynamic chord.

 

  4.8 Performance, where applicable, is based on a fuel Lower Heating Value
(LHV) of *** BTU per pound and a fuel density of *** pounds per U.S. gallon.

 

5 GUARANTEE COMPLIANCE

 

  5.1 Compliance with the guarantees of Section 2 will be based on the
conditions specified in those sections, the Aircraft configuration of Section 3
and the guarantee conditions of Section 4.

 

  5.2 Compliance with the following guarantees or portions of such guarantees
will be based on the FAA-approved Airplane Flight Manual for the Model 737-10
aircraft:

 

  •   Takeoff

 

  •   Landing

 

  •   Enroute One-Engine-Inoperative Altitude

 

  •   The initial buffet portion of All Engines Operating Altitude Capability

 

  •   The takeoff portion of the mission conditions

  5.3 Compliance with the takeoff guarantee and the takeoff portion of the
mission guarantee will not be contingent upon acceptance of a Change Request,
Master Change or Change Order to allow operation at an alternate forward center
of gravity limit or selection of the alternate go-around flap procedure (Flaps
5).

 

  5.4 Compliance with the altitude capability guarantee and with the climb,
cruise and descent portions of the mission guarantees will be established by
calculations based on flight test data obtained from an aircraft in a
configuration similar to that defined by the Detail Specification.

 

  5.5 Compliance with the mission *** guarantee may exceed the design weights in
the FAA-approved Airplane Flight Manual for convenience of calculating *** for
the specified payload. Such exceedance is not to be construed as authorization
to operate the aircraft above the weights in the FAA-approved Airplane Flight
Manual.

 

  5.6 The OEW used for compliance with the mission guarantees will be the actual
MEW plus the Standard and Operational Items Allowance in Appendix E of the
Detail Specification.

 

  5.7 The data derived from tests will be adjusted as required by conventional
methods of correction, interpolation or extrapolation in accordance with
established engineering practices to show compliance with these guarantees.

 

  5.8 Compliance will be based on the performance of the airframe and engines in
combination, and will not be contingent on the engine meeting its manufacturer’s
performance specification.

 

6 EXCLUSIVE GUARANTEES

 

    The only performance guarantees applicable to the Aircraft are those set
forth in this Attachment.
