A. SCOPE

The scheduled maintenance requirements described in this section result from Model 767 airplane certification activities with th

Administration (FAA). Accordingly, this FAA approved Airworthiness Limitations and Certification Maintenance Requirements dreferenced in the Model 767 Type Certificate Data Sheet. These maintenance actions are mandatory.This Airworthiness Limitations Section is FAA approved and specifies maintenance required under Federal Aviation Regulation unless an alternative program has been FAA approved.AIRWORTHINESS LIMITATIONS – STRUCTURAL INSPECTIONSThe Airworthiness Limitations may only be revised with the approval of the Seattle FAA Aircraft Certification Office (ACO).If the inspections cannot be accomplished due to repairs and/or modifications, an alternate inspection approved by the Seattle 

CERTIFICATION MAINTENANCE REQUIREMENTS (CMRs)These scheduled maintenance tasks may only be revised by the Seattle FAA ACO (appropriate regulatory authority). Principal (local regulatory authority) may not change these requirements or the intervals associated with these requirements.

B. AIRWORTHINESS LIMITATIONS – STRUCTURAL INSPECTIONS

The Structural Inspection Program approved in Section 3 of the 767 Maintenance Review Board (MRB) Report and contained i

describes an initial baseline structural maintenance program for all Structural Significant Items (SSIs). This program was deve

the guidelines of MSG-3 and partially satisfies the requirements of FAR 25.571 by providing accidental and environmental dam

for all SSIs, and in some cases, fatigue damage detection opportunity until the supplemental inspection threshold is reached. T

inspections listed in this Section 9 “Airworthiness Limitations” are for those SSIs that do not receive adequate fatigue damage dthe initial baseline structural program that is listed in Section 2 and in Appendix K. The inspections shown in this section and Ap

accomplished in conjunction with and not as a substitute for the existing structural maintenance program found in Section 2.

The supplemental structural inspection program uses the Damage Tolerance Rating (DTR) system to determine the inspection

necessary to provide adequate fatigue damage detection. The DTR system defines a required DTR (a numerical value) that mSSI. DTR Check Forms which define the inspection options and the required DTR are contained in Document D622T001-DTRTHRESHOLDThe certifying authority (Seattle FAA ACO) requires designation of all SSIs into two categories. These two categories are refer

If part usage history data is not available, but records indicate that no part changes have occurred between history data can be used to start a tracking program for the supplemental inspections.

In addition to the thresholds described above, a calendar threshold of 20 years applies unless an initial inspection of an FAA apPrevention and Control Program (CPCP) has occurred, constituting CPCP implementation.The information contained in Appendix K has been added to comply with the AD 2003-18-10 requirements when an airplane re

Appendix K contains the 1995-1999 versions of MPD SeInspection Program, and is the baseline structural inspection program associated with the October 2002 MPD Section 9, AirwoCMRs.

The airworthiness limitations listed in Section 9 are supplemental structural inspections of the SSIs for wnot satisfied by the baseline structural inspections defined in Appendix K. Any continued escalation beyond the MPD baseline sresult in additional structure not meeting the required DTR which was the basis of certification. The inspections shown in Sectio

D. AIRWORTHINESS LIMITATIONS – SYSTEMS

INTRODUCTION

This section of the Airworthiness Limitations contains an FAA approved program of scheduled inspections and design limitation

incorporate into their maintenance program for this type design to meet the new standards and assumptions introduced by § 25Aviation Regulation No. 88 (SFAR 88). SFAR 88 – Fuel Tank System Fault Tolerance Evaluation Requirements and Title 14 C

§ 25.981 – Fuel Tank Ignition Prevention require maintenance instructions, and control limitations for certain fuel tank critical de

Paragraph 2(a) of SFAR 88 requires certain design approval holders of Type Certificates (TCs) and Supplemental Type Certific

transport airplanes to conduct a safety review of the fuel tank systems. The purpose of the safety review is to identify design fe

development of ignition sources in the fuel tank systems. Fuel System Airworthiness Limitations (AWLs) are mandatory mainten

accordance with § 25.981, to ensure that unsafe conditions identified by the safety review do not occur or are not introduced inresult of configuration changes, repairs, alterations, or deficiencies in the maintenance program throughout the operational life 

may be an Airworthiness Limitation Instruction (ALI) or a Critical Design Configuration Control Limitation (CDCCL).CDCCLs are a means of identifying certain design configuration features intended to preclude a fuel tank ignition source for the airplane. CDCCLs are mandatory and cannot be changed or deleted without the approval of the Seattle FAA ACO or applicable 

critical fuel tank ignition source prevention feature may exist in the fuel system and its related installation or in systems that, if a 

develop, could interact with the fuel system in such a way that an unsafe condition would develop without this limitation. Strict a

methods, techniques, and practices as prescribed is required to ensure compliance with the CDCCL. Any use of parts, method

not contained in the applicable CDCCL must be approved by the Seattle FAA ACO or applicable regulatory agency.ALIs identify inspection tasks related to fuel tank ignition source prevention which must be done to maintain the design level of life of the airplane. These ALIs are mandatory and cannot be changed or deleted without the approval of the Seattle FAA ACO agency. Strict adherence to methods, techniques and practices as prescribed is required to ensure the ALI is complied with. Atechniques or practices not contained in these ALIs must be approved by the Seattle FAA ACO or applicable regulatory agency

USE OF ALTERNATE OR EQUIVALENT TOOLS, TEST EQUIPMENT OR MATERIALSFor AWLs which list the use of certain tools, test equipment or materials, use of alternate or equivalent tools, test equipment or approval from the Seattle FAA ACO.The Component Maintenance Manuals (CMM) listed in the AWLs are currently FAA Seattle ACO approved. If the CMM allows equivalent tools, test equipment or materials, use of an alternate or equivalent tool, test equipment or material does not require FAA Seattle ACO.EXCEPTIONAL SHORT-TERM EXTENSIONSSince AWL intervals are based on estimations of the probability of an event, an exceptional short-term extension for each fuel sdocument may be made without jeopardizing safety. The local regulatory authority (e.g. a Principal Maintenance Inspector) mexceptional short-term extensions before they take place using procedures established with the local regulatory authority in the “exceptional short-term extension” process is applicable to AWL intervals. It should not be confused with the operator’s “short-tnormal maintenance tasks described in the operators’ manuals and in the Flight Standards Handbook 8900.1.The Seattle FAA ACO has accepted that these exceptional short-term extensions may be granted without consultation with tha1. The term "exceptional short-term extension" is defined as an increase in a fuel system AWL interval that may be needed to

management practices. Exceptional short-term extensions must not be used for fleet AWL extensions. 

After a fuel system AWL has experienced an exceptional short-term extension, the AWL interval will revert back to its interval liSeattle FAA ACO must approve, prior to its use, any desired extension not explicitly listed above.This exceptional short-term extension listed above applies to airlines that fall under the United States FAA jurisdiction only. Op

the U.S FAA jurisdiction should obtain interval extension approvals from their local regulatory agency.

Title 14 Code of Federal Regulations Sections 121.703 and 135.415 state that “each certificate holder shall report any failure, m

aircraft, system, component, or powerplant that occurs or is detected at any time if, in its opinion, that failure, malfunction, or de

may endanger the safe operation of an aircraft”. Section 125.409 also requires reporting of failures, malfunctions or defects. In 

failure or malfunction will be obvious, but there are some failure modes related to uncontrolled high thrust that are reportable bufollowing information is provided, as required by FAA Exemption No. 8119, to assist the operators in identifying reportable malfuncontrolled high thrust.The FAA has concluded that the loss of capability to control thrust due to a failure of the engine thrust control system may enda

includes any malfunctions having one or more of the following characteristics:• Auto-acceleration or uncommanded thrust change to higher power• Stuck thrust lever above idle power• Inability to reduce thrustAlthough some of these incidents may not appear to be safety related, documenting the events is important to ensure the prese

phrases:• “thrust control”• “no response to thrust lever”• “auto-acceleration”• “uncontrolled high thrust”
