### SUMMARY

This document contains the system Certification Ma intenance Requirements for the Fokker F28 Mk0070 and the F28 Mk0100 aircraft. The selection of the CMR tasks from the System Safety Analysis tasks (CS/JAR/FAR 25.1309) is based on FAA AC 25-19 and JAA AMJ 25-19.

This report is inserted into the Airworthiness Limita tions Section (ALS) of the Instructions for Continued Airworthiness (ICA).

Please take notice of the following:

As from MRB report revision 14, the Airworthiness Limi tations Section (ALS) is removed from the MRB report and published separately in order to harmonize the MR B with other manufacturer platforms and to clearly distinguish tasks selected from t he MSG-3 process (MRB) from tasks required to meet certification requirements (ALS).

As soon as the ALS is revised an e-mail notification will be sent to the Operators. To receive such a notification, “Notification of updates in the Documentation download Center (pdf files)” needs to be selected in the personal mailing list on the myfokkerfleet.c om website. Furthermore the Airworthiness Recommendation Catalogue (A RC) will be updated. As soon as the (new / revised) ALS Airworthiness Directive is available; the ARC will be updated again.

*CMR 783500-CM-01

 First CMR inspection has to be accomplished:

within one year or 3000 FH (whichever comes fi rst) from the issue date of this report SE-473, issue 11 (but not later than 10000 FH since la st accomplishment of MRB task 783500-02-01)

OR

within 8889 FH since last MRB in spection if this comes later.

## SECTION 0

1. SCOPE

This document contains the system Certif ication Maintenance Requirements (CMR's), for the Fokker F28 Mk0070 and the F28 Mk0100.

IMPORTANT: The requirements given in this document ar e mandatory, except in sofar that interval escalations, can be justified in accordan ce with the procedure stated herein. Non-compliance suspends the validity of the Airworthiness Certificate.

The identification of CMR tasks in no way diminish es the importance of non-CMR tasks and changes to these are subject to normal practices and procedures between the operator and the National Regulatory Authority.

This document does not take into account Airworthin ess Directives (BLA/ADs) wh ich, if issued against a system CMR, supersede the specific requirement given in this document.

2. APPLICABILITY

This document is applicable fo r the Fokker F28 Mk0070 and the F28 Mk0100 model aircraft, the effectivity of each individual CMR task is identified.

## SECTION 1: SYSTEM CMR's

1. CRITERIA FOR IDENTIFICATION

System Certification Main tenance Requirements (CMR's) are tasks arising from the Type Certification process which are associated with the most significant failure conditions. These have been shown to be necessary ei ther by System Safety Assessment (e.g.: CS/JAR/FAR 25.1309 compliance) or, in a minority of cases, by engineering judgment. These requirements are allocated to one of two categories (identified as One Star or Two Star) according to AC/AMJ 25-19.

Tasks associated with the following cr iteria are 'not identified' as CMR's:

(1) Tasks related to failure condit ions with minor and major effects. These tasks are considered as important as all other tasks to keep the airc raft in good condition and do not need special emphasis.

(2) Maintenance actions (for simple and for c onventional systems) considered to be routine maintenance activity (MRB tasks) based on engineering judgment and experience on similar airplane types.

(3) Tasks, as part of the crew check list, in cluded in the approved Airplane Flight Manual.

2. HANDLING OF SYSTEM CMR's

2.1. CMR "One Star" task

The tasks and intervals specified are mandatory and cannot be changed, escalated, or deleted without the concurrence of the responsible Certificating Authority.

2.2. CMR "Two Star" task

Task intervals may be adjusted in accordance with an operator's approved escalation practices or an approved reliability program, but the task may not be ch anged or deleted without prior approval by the responsible Certification Authority.
