Under 14 CFR Part 39, what is an Airworthiness Directive (AD)?
Answer: A legally enforceable regulation requiring correction of an unsafe condition in a type-certificated product
Airworthiness Directives are legally enforceable regulations issued under 14 CFR Part 39 to correct unsafe conditions in type-certificated products.
An ASI finds that a recurring AD on an aircraft engine was last complied with 400 hours ago, and the AD requires compliance every 300 hours. What is the aircraft's airworthiness status?
Answer: Not airworthy due to non-compliance with a mandatory Airworthiness Directive
Failure to comply with a recurring AD within the specified interval renders the aircraft not airworthy, as ADs are mandatory federal regulations.
When an ASI encounters a Special Airworthiness Information Bulletin (SAIB), what action is required of the aircraft operator?
Answer: No mandatory action is required — SAIBs are informational and non-mandatory
SAIBs are non-mandatory informational documents that provide safety-related information but do not require compliance unlike Airworthiness Directives.
An aircraft owner requests a Special Flight Permit to fly an unairworthy aircraft to a maintenance facility. Under 14 CFR §21.197, which condition would disqualify the aircraft from receiving this permit?
Answer: The aircraft presents a hazard to persons or property in flight or on the ground
14 CFR §21.197 specifies that a Special Flight Permit cannot be issued if the aircraft presents a hazard to persons or property, as the permit is only for aircraft that can still be safely operated for a specific limited purpose.
During an inspection, an ASI discovers the aircraft's compass has not been swung (calibrated) after several avionics installations. What regulation governs compass calibration requirements?
Answer: 14 CFR §43 Appendix D — scope and detail of annual inspections
14 CFR Part 43, Appendix D specifies that the magnetic compass calibration (compass swing) is a required item in the scope of an annual inspection.
An ASI finds that an aircraft has a Supplemental Type Certificate (STC) modification installed, but the aircraft logbook shows the STC data package is missing. What is the most serious airworthiness concern?
Answer: The modification cannot be verified as properly approved and installed per the STC, potentially making the aircraft not airworthy
Without the STC data package, the ASI cannot verify the modification was installed in accordance with its approved data, which is a fundamental airworthiness concern.
Which section of 14 CFR defines what constitutes a 'major repair' versus a 'minor repair' for aircraft?
Answer: 14 CFR Part 43, Appendix A — major alterations, major repairs, and preventive maintenance
14 CFR Part 43, Appendix A provides the list and criteria that distinguish major repairs and major alterations from minor ones.
