1.- AIRWORTHINESS LIMITATIONS 1.1 INTRODUCTION During the CN-235-300 MP (Maritime Patrol) certification program certain maintenance tasks have been

identified that must be performed on all aircraft at, or before, the required interval, in order to meet certification requirements. These task intervals must not be escalated without the approval of the EADS-CASA Engineering Division (División de Proyectos) and the Airworthiness Authorities.

1.2 SCOPE Three types of tasks are included in the Airworthiness Limitations: a) SYSTEMS related tasks where a limiting interval has been calculated in a safety assessment to

achieve compliance with certification regulations. For ease of identification, systems tasks are identified in the MRB CN-235 PV01 Document. In the event of conflicting information, the present (Airworthiness Limitations) Document will be the final authority.

b) STRUCTURES related tasks where inspections must be performed at, or before, the prescribed

thresholds/intervals in order to detect fatigue cracks before the critical crack length is reached. c) Discard tasks for safe life STRUCTURAL items. 1.3 RULES APPLICABLE TO THE AIRWORTHINESS LIMITATIONS LIST a) No task may be deleted, and no task interval may be escalated without the approval of the EADS-

CASA Engineering Division and Airworthiness Authorities. b) Systems Maintenance tasks and Fatigue Damage tasks identified in the Airworthiness Limitations

may only have the task deleted or the threshold/interval escalated with the approval of the EADS-CASA Engineering Division and Airworthiness Authorities.

c) Items that are life limited will be discarded according to the life limits published in the Airworthiness

Limitations. These limits may be revised per the manufacturers recommended guidelines with the approval of the regulatory authority.

regulation.

1.4.2 Structural Inspection Limitations

A Damage Tolerance Analysis (Fatigue, crack growth, and residual strength analyses) has been made in order to obtain for each SSE a particular threshold and interval for inspection that will assure the economic and safe operation of the aircraft.

Structures maintenance tasks and their associated inspection thresholds and intervals arising from damage tolerance evaluation (FAR 25.571) will be identified following review of the results of the relevant full scale fatigue testing. Values (thresholds and intervals) to be corfirmed when final analysis of test results is completed.
