### 1. General

During the Fokker 70 and Fokker 100 certificati on process certain Maint enance Requirements have been identified which must be performed on ALL aircraft at or before the intervals or times specified in order to meet the certification requirements. Th ese mandatory Maintenance Requirements are identified as Airworthiness Limitations.

The Airworthiness Limitations are:

1. Certification Maintena nce Requirements (CMR's) CMR's are tasks on Systems & Power Plant where a limiting interval has been established from the System Safety Assessment to achieve comp liance with the certification requirements as defined in JAR/FAR 25.1309.

2. Airworthiness Limitation Items (ALI's) ALI's are tasks in the Structure and System & Power Plant Programs where a limiting interval has been established resulting from the Fatigue and Damage Tolerance Assessment to achieve compliance with the certification re quirements as defined in JAR/FAR 25.571.

3. Safe Life Items (SLI's) SLI's are certain aircraft and engine parts with a retirement (replacement) life. The retirement lives for the aircraft are specified in this report.

4. Fuel Airworthiness Limitation Items: as applied to the Fuel Tank system safety policy, this term means fuel system mandatory maintenance insp ections determined neces sary to ensure that unsafe conditions do not arise in the fuel system throughout the operational life of the aircraft.

5. Critical Design Configuration Control Limitations (CDCCL): as applied to the Fuel Tank system safety policy, this term refers to a feature of any aircraft system which must be retained during modification, change, repair or scheduled maint enance to ensure that an unsafe condition does not develop in the fuel system.

This report SE-623 specifies both the ALI's and the SL I's. Report SE-473 specifies the CMR’s and report SE-672 specifies the Fuel ALI’s and CDCCL’s. All reports are inserted into the Airworthiness Li mitations Section of the MRB document, Appendix 1. MRB Appendix 1 is referenced in the Type Certificate Data Sheet.

No Maintenance Task, specified herein may be c hanged or deleted and no intervals, thresholds and times specified may be escalated without the approval of the National Regulatory Authority after consultation with the manufact urer's certification authority.

### 2. Airworthiness Limitation Items (ALI's)

2.1. General

These are tasks in the Structur e or Systems and Powerplant Program where a limiting interval resulting from the Fatigue and Damage Tolerance Analysis has been established to achieve compliance with the certification regulations.

2.2. Airworthiness Limitation Items - Tasks and Intervals

ALI's with a life of 90000 FC or higher are not mentioned (except for landing gear components).

### 2.3. Conversion table of Nose Landing Gear and Main Landing Gear ALI's to next higher (sub-)assembly

Life limited components as given in paragraph 2. 2 do refer to the actual life limited components (ALI's bare partnumbers) and their retirement lives as established from the Fatigue and Damage Tolerance Analysis.

Common maintenance practice is to exchange a replaceable unit when retarding a life limited component. The replaceable unit could consist of the (actual) ALI, including parts such as bushes, wire meshes, grease nipples.

The following table shows the relation between the actual life limited components (ALI's) as given in the tables of paragraph 2.2 and the next higher (sub-) assemblies, i.e. replaceable unit.
