### Summary:

This report specifies the Fuel Airworthiness Limitation Items (Fuel ALIs) and the Critical Design Configuration Control Limitations (CDCCL) required to prevent the dev elopment of unsafe conditions within the fuel system.

This report is inserted into the Airworthiness Limitati ons 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.

### 1. General

During the F28 Mk0070 and F28 Mk0100 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. 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 compliance wi th the certification requirements as defined in JAR/FAR/CS 25.1309.

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

3. Safe Life Items (SLI's) SLI's are certain aircraft and engine parts with a retirement (replacement) life.

4. Fuel Airworthiness Limitation Items: as applied to the Fuel Tank system safety policy, this term means fuel system mandatory maintenance insp ections 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 maintena nce to ensure that an unsafe condition does not develop in the fuel system.

This report SE-672 specifies the Fuel ALI’s and CDCCL’s. Report SE-623 specifies both the ALI's and the SLI's as mentioned under 2 and 3. Report SE-473 specifies the CMR’s. These reports are inserted into t he Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA). For more details on the ALS, reference is made to the MRB report, Appendix 1.

Operators are expected to demonstrate to their Airworthiness Aut hority Maintenance Inspector that the required configuration control systems are in place to ensure that CDCCL’s are properly identified and managed.

### 2. Fuel Airworthiness Limitation Items (ALI)

2.1. General

As applied to Fuel Tank system safety policy, th is term means fuel system mandatory maintenance inspections determined necessary to ensure that uns afe conditions do not arise in the fuel system throughout the operational life of the aircraft.

2.2. Exceptional short-term extensions

Since Fuel ALI Maintenance/Inspection intervals are generally not determined from calculations in which failure rate data is known with a high level of confidence, an exceptional short-term extension for a specific Fuel ALI interval may be made on one aircraft for a limited period of time without jeopardizing safety.

The term 'exceptional short-term extension' is defined as an increase in a Fuel ALI interval that may be needed to cover an uncontrollable or unexpected situation. Repeated use of such extensions, either on the same aircraft or on similar aircraft in the operator's fleet, should not be used as a substitute for good management practices.

Unless noted adjacent to the task, for all Fuel ALI’s identified in this report, it has been accepted by the Primary Certification Office (EASA) that shor t-term extensions up to the following maximum values may be granted without consultation with that office. Requests for extensions in excess of these values must be submitted with full justificati on to the Primary Certification Office (EASA) such that approval, if granted, can be given prior to their use.

- Fuel ALI’s controlled by Flight Hours (FH)

Extensions up to 10% or 500 FH (whichever is the lesser) may exceptionally be granted on Fuel ALI intervals quoted in terms of flight hours.

- Fuel ALI’s controlled by Flight Cycles (FC)

Extensions up to 5% or 250 FC (whichever is the lesser) may exceptionally be granted on Fuel ALI intervals quoted in terms of flight cycles or landings.

- Fuel ALI’s controlled by Calendar Time (MO)

Where the repeat interval is 12 months or less, extensions up to 10% or 1 month (whichever is the lesser) may exceptionally be granted on Fuel ALI intervals quoted in terms of months.

Where the repeat interval is greater than 12 mont hs but less than 3 years, extensions up to 2 months may exceptionally be granted.

Where the repeat interval is 3 years or greater, extensions up to 3 months may exceptionally be granted.

### It is the responsibility of the operator to identify appropriate procedures with his local regulatory authority for the control and devel opment of his maintenance prog ram. (Note EASA: The operator should keep a record of short term extensions given for Fuel Airworthiness Limitation Items).

This paragraph is written to confirm to the loca l regulatory authority that exceptional short-term extensions of Fuel ALI intervals are permissible. Approval of such extensions rests with the local authority in the same way as it does for any other scheduled maintenance task interval extension.
