Maintenance Publications

Question 1

8492. Airworthiness Directives are issued primarily to
      A— provide information about malfunction or defect trends.
      B— present recommended maintenance procedures for correcting potentially hazardous defects.
      C— correct an unsafe condition.

Answer 1

C— correct an unsafe condition

The FAA issues ADs to correct unsafe conditions that have been discovered on certificated aircraft, engines, propellers, or appliances.
An unsafe condition causes the device to fail to meet the conditions for its certification. An AD specifies the corrective action that must be taken to return the device to the conditions specified for its certification.

Question 2

8493. (1) A Supplemental Type Certificate (STC) may be issued to more than one applicant for the same design change, providing each applicant shows compliance with the applicable airworthiness requirement.

(2) An installation of an item manufactured in accordance with the Technical Standard Order (TSO) system requires no further approval for installation in a particular aircraft. Regarding the above statements,
A— both 1 and 2 are true.
B— neither 1 nor 2 is true.
C— only 1 is true.

Answer 2

C— only 1 is true.

Statement 1 is true. More than one person may apply for a STC that covers the same change to an aircraft.
An STC is not a patent and it is not protected. Each applicant must furnish proof that their alteration meets all of the applicable airworthiness requirements.
Statement 2 is not true. A part produced according to a TSO requires specific approval for installation on a particular aircraft. Even though the part is built according to a TSO, it may be neither suitable nor approved for the particular aircraft.

Question 14

8503-1.
Which of the following are sometimes used as authorization to deviate from an aircraft’s original type design?
A— FAA Form 337, Supplemental Type Certificate, and Technical Standard Order.
B— Supplemental Type Certificate, Airworthiness Directive, and Technical Standard Order.
C— FAA Form 337, Supplemental Type Certificate, and Airworthiness Directive.

Answer 14

C— FAA Form 337, Supplemental Type Certificate, and Airworthiness Directive.

The FAA Form 337 is the form the FAA uses to authorize a major alteration that may deviate from the aircraft’s original type design.
An STC is an authorization for a major change in the type design that is not great enough to require a new application for a type certificate.
An AD identifies an unsafe condition that exists in a product and that is likely to exist or develop in other products of the same type design. ADs may require alterations that deviate from the aircraft’s original type design.
A TSO is a minimum performance standard used to evaluate an article. An article can be a material, part, component, process, or appliance (see 14 CFR §21.1(b) (2)). Each TSO covers a certain type of article. When authorized to manufacture an article to a TSO standard, this is referred to as a TSO authorization. Receiving a TSO authorization is both a design and production approval but is not used as an authorization to deviate from an aircraft’s original type design.

Question 15

8504. (1) The Federal Aviation Regulations require approval after compliance with the data of a Supplemental Type Certificate.

(2) An installation of an item manufactured in accordance with the Technical Standard Order system requires no further approval for installation in a particular aircraft.
Regarding the above statements,
A— only 2 is true.
B— neither 1 nor 2 is true.
