NOTE:  In ADs prior to March 1, 2002, “Model DC-9 series airplanes,” as listed in the applicability of the AD, 
included those models listed in rows one through five above, but did not include DC -9-81 (MD-81), -82 (MD-82), -
83, (MD-83), and -87 (MD-97) airplanes.  If all Model DC-9 series airplanes are NOT subject to the requirements of 
the AD, the applicability of the AD lists each affected model.  Also, with respect to ADs issued prior to March 1, 
2002, the information provided in the table is very general and should not be the only information utilized to 
determine the applicability of ADs to specific airplane models.  The ADs contain separate applicability statements 
that rely heavily on service bulletins for determination of the applicability.

Configuration: (Approved March 3, 1998) 
 
The Saudi Arabian Airlines MD-90-30 configuration is equipped with six-across flight deck Liquid 
Crystal Displays.  For this configuration, an additional certification basis was established. 
 
Based on the date of notification of major changes, April 5, 1996, in conjunction with the MD -90-30 
certification basis, the certification basis for the Saudi Arabian Airlines MD-90-30 configuration is 
Federal Aviation Regulations Part 25, effective February 1, 1965, as amended by Amendments 25-1 
through 25-84.  In addition, a new Special Condition concerning aircraft operations without normal 
electrical power has been applied to the MD-90-30 model equipped with Enhanced Flight Deck 
Configuration.  For those areas and components for which, as part of the original MD -90-30 
certification, exceptions were granted and are not impacted by the changes, no additional justification 
is required.

Certification Basis: (cont’d) 
Model MD-90-30 (cont’d) 
There are four significant changes that constitute a substantial flight deck change and are required to be 
certified to Federal Aviation Regulations Part 25 as amended by Amendments 25 -1 through 25-84. 
These changes relate to the incorporation of the new Electronic Display System which feature an 
integrated flight deck display system with six-across Liquid Crystal Displays. These changes are: 
 
• Six Across Liquid Crystal Displays / Electronic Instrument System 
• Dual Pegasus Flight Management Computers 
• Improved Overhead Control Panel 
• Integrated Standby Instrument System 
 
(Note: Takeoff Operation System / Host Performance Computer portion was canceled and is not 
installed in the Saudi Arabian Airlines Enhanced Flight Deck Configuration.) 
In addition, there are eight major changes that support the flight deck changes.  These are for systems 
and components where a fundamental design change was not made to the system but certain changes 
were necessary for interfacing these systems and components to the new flight deck.  These changes 
do not constitute a substantial change and therefore compliance was substantiated to the certification 
basis of the baseline MD-90-30. 
• Brake Temperature Monitor System 
• Pneumatic System Controller Part Number Change 
• Fuel System Interface to Electronic Instrument System (EIS) 
• Flight Deck Lighting 
• Cabin Pressure Acquisition Module 
• Landing Gear Control Handle 
• Control Wheel Interface to EIS

(d) The "unusable" fuel is that amount of fuel, including tank trapped fuel, in the tanks which is 
unavailable to the engines under critical flight conditions as defined in CAR 4b.416 (DC -9-11 
thru -51) or FAR 25.959 (DC-9-81, -82, -83, -87, MD-88 , MD-90-30 and 717-200) and may 
be obtained by taking the differences between the "total" and "usable" tank capacities shown 
under "fuel capacity."  This "unusable" fuel is included in system fuel as indicated in 1(c) 
above and need not be accounted for separately. 
 
(e) All weight in excess of the maximum certificated zero fuel weight must be fuel in the main 
tanks, except for Models DC-9-31, -32, -32F, -33F, -34, -34F, -41, -51, -81, -82, -83, -87,
