Question 8Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

An airworthiness directive is issued when the FAA finds that

  1. an operator has requested an extension of a maintenance interval
  2. a repair station lacks a current quality manual
  3. an unsafe condition is likely to exist in other products of the same design Correct answer.
  4. a single aircraft has been operated beyond its approved maintenance interval

Explanation

An airworthiness directive addresses an unsafe condition found in an aircraft, engine, propeller, or appliance. The FAA issues it when the unsafe condition is likely to exist or develop in other products of the same type design. ADs are mandatory and enforceable.

Question 9Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

  4. Six months after the work is performed

Explanation

Part 91.417 requires maintenance records to be retained for at least one year after the work is performed or until the work is repeated or superseded by another record. Certain other records, such as AD compliance records, have different retention requirements.

Question 13Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

  1. parked indefinitely
  2. used exclusively for personal pleasure
  3. operated for compensation or hire Correct answer.
  4. used only for training without compensation

Explanation

Part 91.409 requires a 100-hour inspection for aircraft operated for compensation or hire or used for flight instruction for hire, subject to certain exceptions. Personal and non-compensated operations generally fall under the annual inspection requirement instead.

Question 20Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

If an annual inspection finds an aircraft unairworthy, what must the inspector provide to the owner?

  1. Only the owner's written approval
  2. No data, so the repair cannot be performed
  3. Data acceptable to the FAA Administrator Correct answer.
  4. Any data from the internet

Explanation

Part 43.13 allows a person performing maintenance to use data acceptable to the Administrator when the manufacturer's manual or instructions for continued airworthiness do not contain the needed method. The data must be appropriate for the task and approved as required.

  2. Perform an annual inspection
  3. Approve a major repair for return to service without further authorization
  4. Approve a major alteration for return to service

Explanation

Part 65.81 allows a certificated mechanic to perform maintenance and alterations but prohibits approving a major repair or major alteration for return to service unless authorized under Part 43. An inspection authorization is one route to that approval authority.

Question 25Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

For an experimental amateur-built aircraft certificate, the major portion of the aircraft must be

  1. designed by the FAA
  2. assembled by a Part 121 certificate holder
  3. built and assembled by the amateur builder Correct answer.
  4. manufactured by a certificated repair station

Explanation

Part 21 provides for an experimental certificate for amateur-built aircraft when the major portion of the aircraft has been fabricated and assembled by the amateur builder for education or recreation. The aircraft is not eligible for this category if the major portion is commercially built.

Question 26Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

Question 29Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

Under Part 39, no person may operate a product to which an airworthiness directive applies unless the product is operated and maintained in accordance with which of the following?

  1. A field approval issued by the local FAA office
  2. The manufacturer's service bulletin covering the same subject
  3. The requirements of the airworthiness directive Correct answer.
  4. An inspection performed by an inspection authorization holder

Explanation

Part 39 prohibits operation of a product to which an AD applies unless the product is operated and maintained in accordance with the AD's requirements. A service bulletin or field approval does not substitute for compliance with the AD.

Question 30Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

Which task is classified as preventive maintenance under Part 43 Appendix A?

  2. Conforms to its type certificate and is in condition for safe operation Correct answer.
  3. Has been approved by the manufacturer's quality control system
  4. Is operated only under Part 91

Explanation

A standard airworthiness certificate is issued when the FAA finds that the aircraft conforms to its approved type design and is in condition for safe operation. Completion of a 100-hour inspection or the operator's part 91 status does not itself establish eligibility for the certificate.

Question 33Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

  1. In the pilot's logbook
  2. In the aircraft maintenance records Correct answer.
  3. Only in the engine logbook
  4. On FAA Form 337

Explanation

Section 91.417 requires the owner or operator to keep a record of the current status of applicable airworthiness directives, including the method of compliance and the date and time in service, if recurring. That record is part of the aircraft maintenance records.

Question 36Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

Technical data for a major repair must be approved by which of the following?

  1. Returned to service without a maintenance record
  2. Inspected only by the manufacturer
  3. Inspected in segments at specified intervals instead of in a single annual inspection Correct answer.
  4. Operated without any annual inspection

Explanation

A progressive inspection program allows the aircraft to be inspected in segments at specified intervals, provided the program is approved by the FAA. It replaces the single annual inspection while maintaining equivalent inspection coverage.

Question 39Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

Explanation

A major alteration is an alteration not listed in the aircraft specifications or made in accordance with accepted practices that might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or airworthiness. Changing wing spar structure affects structural strength and is a major alteration.

Question 40Regulations (14 CFR parts 1, 21, 39, 43, 45, 65, 91, 121, 135) and Airworthiness Directives

After a major alteration on an aircraft operated under Part 91, who may approve the aircraft for return to service?

  1. The parts supplier
  2. The aircraft owner
  3. An inspection authorization holder or a certificated repair station Correct answer.
  4. Any pilot holding a private pilot certificate

Explanation

Return to service after a major alteration requires approval by a person authorized under Part 43, such as an inspection authorization holder or an appropriately rated certificated repair station. The owner, a private pilot, or a parts supplier does not have that authority.

Explanation

Section 43.9(a) requires the entry to contain a description of the work or a reference to acceptable data, the date of completion, the name of the person performing the work, and the signature and certificate number of the person approving it for return to service. Weight and balance data may be revised after some alterations, but it is not an element of the 43.9 entry itself.
