ASI Aircraft Airworthiness Inspection 3

Question 1

Under 14 CFR Part 39, what is an Airworthiness Directive (AD)?

Accepted Answer

A legally enforceable regulation requiring correction of an unsafe condition in a type-certificated product

Answer

A voluntary service bulletin issued by the manufacturer to improve aircraft performance

Answer

An FAA advisory circular recommending but not requiring specific maintenance actions

Answer

A manufacturer's warranty requirement for maintaining aircraft in serviceable condition

Question 2

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?

Accepted Answer

Not airworthy due to non-compliance with a mandatory Airworthiness Directive

Answer

Airworthy, as long as no mechanical problems are evident

Answer

Conditionally airworthy pending an engine borescope inspection

Answer

Airworthy if the operator obtains an alternate means of compliance (AMOC)

Question 3

When an ASI encounters a Special Airworthiness Information Bulletin (SAIB), what action is required of the aircraft operator?

Accepted Answer

No mandatory action is required — SAIBs are informational and non-mandatory

Answer

Immediate compliance is required as SAIBs carry the same legal force as ADs

Answer

Compliance must be documented on FAA Form 337 within 30 days

Answer

The SAIB must be incorporated into the aircraft's approved maintenance program

Question 4

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?

Accepted Answer

The aircraft presents a hazard to persons or property in flight or on the ground

Answer

The aircraft has an expired annual inspection

Answer

The aircraft requires a part that will take more than 30 days to obtain

Answer

The aircraft's airworthiness certificate has been suspended for more than 60 days

Question 5

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?

Accepted Answer

14 CFR §43 Appendix D — scope and detail of annual inspections

Answer

14 CFR §91.205 — required instruments for VFR/IFR flight

Answer

14 CFR §91.413 — ATC transponder tests and inspections

Answer

14 CFR §43.13 — performance rules for maintenance

Question 6

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?

Accepted Answer

The modification cannot be verified as properly approved and installed per the STC, potentially making the aircraft not airworthy

Answer

The STC holder's warranty is void without the data package on board

Answer

The aircraft loses its ability to operate under IFR until the data package is located

Answer

Only the weight and balance data needs to be present, not the full STC package

Question 7

Which section of 14 CFR defines what constitutes a 'major repair' versus a 'minor repair' for aircraft?

Accepted Answer

14 CFR Part 43, Appendix A — major alterations, major repairs, and preventive maintenance

Answer

14 CFR §43.1 — applicability

Answer

14 CFR §91.409 — inspection requirements

Answer

14 CFR §65.95 — privileges and limitations of inspection authorizations
