Airworthiness Requirements

1. Airworthiness Limitations General

This appendix provides a complete listing of structural and systems Airworthiness Limitations

(AWL). The Airworthiness Limitations comprise a section of the Instructions for Continued

Airworthiness and list each mandatory replacement time and structural inspection interval arising

out of the Damage Tolerance certification activities and equipment qualification testing.

The Structural AWLs are applicable to the Principal Structural Elements (PSEs) of the primary

structure, which are identified in the Task Description column of the Structural Airworthiness

Limitations table in Appendix B.

For High Altitude Airfield Operation (HAAO) aircraft, an inspection interval has been defined for

selected AWL items. Refer to the Post−Modsum TC601R15827 inspection interval, where

applicable, in the Structural Airworthiness Limitations table.

The information contained in this appendix may be changed to reflect service and/or test

experience or new analysis methods. Any change(s) to task or intervals listed in this appendix

must be done in conjunction with the appropriate regulatory agency(ies).

The tasks are also listed in the Regional Jet Maintenance Review Board Report, Part 1, Section

3, Structures Maintenance Program, for reference purposes. The inspection thresholds and

repeat intervals are not listed in the MRB Report.

The Threshold period and Repeat inspection intervals are expressed in number of landings. A

flight is equivalent to a landing cycle. The Threshold period is the initial period of aircraft utilization

up to the first inspection. The Repeat inspection interval is the period between each subsequent

inspection.

The Threshold inspection shall be calculated from the time of aircraft manufacture (0 landings).

The Repeat inspection interval shall commence after the Threshold inspection is accomplished.

For AWL items that include an EFFECTIVITY statement (example; Post−Modsum TC601R15054

or Post−SB 601R−53−059), the Threshold inspection shall be calculated from the time of aircraft

modification, unless otherwise stated.

Inspections of AWL items can be accomplished at any time prior to reaching the specified

threshold and/or subsequent inspection intervals. However, if a task is carried out prior to the

specified airworthiness limitation in Part 2, the next subsequent interval starts counting

immediately.

2. Structural and Systems Component Life Limits General

The structural and systems discard times are also initial conservative estimates. The Structural

Life Limit discard times are to be calculated from the number of landings on the aircraft when the

component was installed.

For High Altitude Airfield Operation (HAAO) aircraft, a life limit has been defined for selected Main

Landing Gear (MLG) components. Refer to the STRUCTURAL LIFE LIMITS − HIGH ALTITUDE

AIRFIELD OPERATION (HAAO) − POST−MODSUM TC601R15827 AIRCRAFT ONLY" table for

Life Limit discard times applicable to HAAO aircraft.

The System Components Life Limits discard times are to be calculated from the number of Flight

Hours or APU Hours (as applicable) on the aircraft when the component was installed. The discard

times apply to the part numbers and dash numbers as indicated in this appendix. As analysis and

testing continues, the times will be escalated or the discard requirement will be eliminated entirely.

3. Supplementary Requirements General

This appendix lists supplementary maintenance requirements from a variety of diverse sources,

such as Service Information Letters, Service Bulletins and Canadian issued Airworthiness

Directives applicable to the Regional Jet aircraft (CL600−2B19).

These listings are effective up to, and including, the latest Maintenance Requirements Manual

revision date.

The information contained in this appendix is to be used as a guide only and not to be construed

as all inclusive. Should a discrepancy occur between this Section and a regulatory authority

issued document, the latter will always take precedence.

4. Structural Repair Limitations General

This appendix lists inspection requirements for aircraft damaged during production or during fleet

operations. These inspections comprise a section of the Continued Airworthiness for the aircraft

indicated. The inspection level and inspection threshold/repeat intervals will be incorporated as

they become available. The inspection intervals for these limitations are to be calculated from the

landings at the time of repair.

5. Notes Applicable to the Airworthiness Limitations

NOTE 1 Interim value; Evaluation and test to continue.

NOTE 2 AC Motor Pump 601R75154−5 is replaced by 601R75154−7, which has no life 

limit.

NOTE 3 This task is against optional equipment and may not be installed on all aircraft.

NOTE 4 Detailed Visual or Special Detailed Inspection may be chosen. However, 

whichever inspection method is chosen, the method MUST be adhered to. An 

operator cannot alternate between either method.

NOTE 5 Return to vendor for required inspection.

NOTE 6 Aircraft that have the option of limiting the maximum take−off weight (MTOW) to

52000 lb will apply the inspection program and life limits of the 53000 lb MTOW 

aircraft.

NOTE 7 The part number listed is not serialized or the serial number is not visible 

in−service. The operator can track the flight cycles on this sub−component by the

serial number of the next higher assembly, as identified in brackets within the Part

Name.

6. Safe Life of Landing Gear Components Re−Certified for Revised Maximum Take−Off Weight

(MTOW)

The Safe Life Limit of landing gear components re−certified for revised maximum take−off weight

(MTOW), are to be calculated using the following formula.

STRUCTURAL REPAIR LIMITATIONS FOR THE WING LOWER−PLANK ACCESS−HOLES

DESCRIPTION IN

Structural Repair Limitations for wing lower plank access holes repaired in accordance with the RepairEngineering Orders (REO) listed in Table 1, are detailed as follows:For all access holes, a maximum blend−out limit of 0.082 inch is permitted.A critical region for damage tolerance is defined to be four inches at either side of the access hole minordiameter axis for both forward and aft hole edges. Refer to Figure 2. Blends outside of this region do notaffect the existing inspection requirements in the Maintenance Requirements Manual (AWLs 57−21−146,57−21−147, 57−21−148, and 57−21−149).The operator may elect to inspect repairs in the critical region as follows:OPTION 1 − At time of repair, do an inspection of the repaired area only. The next inspection

interval shall be as per MRM (AWLs 57−21−146, 57−21−147, 57−21−148, and57−21−149) or per Table 2 or 3, whichever comes first. The subsequentinspections are per Table 2 or 3 for both threshold and repeat intervals.

OPTION 2 − At time of repair, do an inspection of the entire circumference of the access hole as

per MRM (AWLs 57−21−146, 57−21−147, 57−21−148, and 57−21−149). Thesubsequent inspections are per Table 2 or 3 for both threshold and repeat intervals.If corrosion lies outside the critical region, do an inspection of the repaired area only.The subsequent inspections shall be per the MRM (AWLs 57−21−146, 57−21−147,57−21−148, and 57−21−149).
