Which of the following is found in the "Instruction for Continued Airworthiness"?

The "Instructions for Continued Airworthiness" (ICA) is a critical document that outlines the maintenance, preventive maintenance, and alteration procedures necessary for the continued airworthiness of an aircraft. The Airworthiness Limitation Section, which is found in the ICA, specifically details the essential procedures and intervals for inspections, maintenance tasks, and checks that must be adhered to in order to maintain the aircraft’s airworthiness.

This section is crucial as it provides mandatory guidelines that ensure the aircraft remains safe and reliable for operation. Each aircraft model's ICA is developed based on the manufacturer’s specifications and requirements. The Airworthiness Limitation Section often includes information related to structural integrity and certain critical components that must undergo regular checks, reflecting the manufacturer's safety concerns and engineering judgments.

Other incorrect options, while relevant to airworthiness and maintenance practices, do not belong in the ICA. Manufacturer's Service Bulletins, for example, are typically advisories issued to inform operators about maintenance and service recommendations, but they do not form a part of the ICA. FAA regulations provide broader guidelines and legal requirements for aviation safety, guiding operational standards but are not specific to the airworthiness of individual aircraft models. Inspection checklists are practical tools used during inspections but are not formal sections within the ICA itself.
