1. General 

During the Fokker 70 and Fokker 100 certification process certain Maintenance 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. These mandatory Maintenance Requirements are identified 

as Airworthiness Limitations. 

The Airworthiness Limitations are: 

1. Certification Maintenance 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 compliance 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 requirements 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 inspections determined necessary 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 maintenance to ensure that an unsafe condition does 

not develop in the fuel system. 

This report SE-623 specifies both the ALI's and the SLI'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 Limitations 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 changed or deleted and no intervals, thresholds and 

times specified may be escalated without the approval of the National Regulatory Authority after 

consultation with the manufacturer's certification authority.

2. Airworthiness Limitation Items (ALI's) 

2.1. General 

These are tasks in the Structure 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.
