Why FAA issues Airworthiness Directives?
FAA issues Airworthiness Directives to correct an unsafe conditions that have been discovered on certificated aircraft, engines, propellers, or appliance.
How is an unsafe condition defined?
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.
A part produced according to a TSO requires special approval for installation on a particular aircraft. Even though the part is built according to a TSO, what may be the case?
It may be neither suitable nor approved for the particular aircraft.
14 CFR Part 21
CERTIFICATION PROCEDURES FOR PRODUCTS AND ARTICLES
governs the issuance of an Airworthiness Certificate.
TSOs are issued by the Administrator under this CFR
Why Control surface movement is important?
The amount of control surface movement determines the structural load that can be put on an aircraft and also the flight characteristic of the aircraft, and this information is also so critical that’s why its included on the TCDS.
What’s an STC (Supplement Type Certificate)?
An STC is an authorization for a major change in the type design that is not great to require a new application for a type certificate.
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.
FAA Form 337
The form the FAA uses to authorize a major alteration that may deviate from the aircraft’s original design.
AD
Airworthiness Directive: 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
What’s a TSO (Technical Standard order)?
A TSO is a minimum performance standard used to evaluate an article. an article can be a material, Part, component, process, or appliance.
(Or an approval for the manufacture of a component for use on certificated aircraft.)
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
14 CFR Part 23
AIRWORTHINESS STANDARDS: NORMAL CATEGORY AIRPLANES
Airworthiness standard for normal, utility, acrobatic, and commuter category airplanes.
14 CFR Part 25
AIRWORTHINESS STANDARDS: TRANSPORT CATEGORY AIRPLANES
Provide airworthiness standards for transport category airplanes.
14 CFR Part 27
AIRWORTHINESS STANDARDS: NORMAL CATEGORY ROTORCRAFT
Provides the airworthiness standard for normal category rotorcraft.
What are the two types of data the FAA issue for aircraft?
1- Regulatory data is approved data that specifies teh way something will be done. it is specific and it must be complied with as it applies.
2- Data in advisory circular, such as thet in AC 43.13-2A, is advisory in nature and is “acceptable data”
What must an entry in the maintenance record of a piece of equipment include?
The method of compliance and the date of compliance.
Aviation Maintenance Alerts
Provide a common communication channel through which the aviation community can economically interchange service experience and thereby cooperate in the improvement of aeronautical product durability, reliability, and safety. The contents include items that have been reported to be significant but have not been evaluated by the time the material went to press.
What a doubler -102 made of ?
it is made of .40 7075-O Alclad, this material is in its annealed (-O) condition, it must be heat treated to its -T6 condition before itis installed.
What a doubler -101 made of?
it is made of 2024-T3 Alclad which is already heat-treated.
How many hours it take to complete an AD?
The AD must be complied with each 200 hours of time in service.
The action required by an AD may take what form?
Inspection
Parts replacement
Design modification
Change in operating procedure
Overall change in the content, form and disposition of aircraft maintenance records
14 CFR 125
CERTIFICATION AND OPERATIONS: AIRCRAFT HAVING A SEATING CAPACITY OF 20 OR MORE PASSENGERS OR A MAXIMUM PAYLOAD CAPACITY OF 6,000 POUNDS OR MORE; AND RULES GOVERNING PERSONS ON BOARD SUCH AIRCRAFT
14 CFR 135
OPERATING REQUIREMENTS: COMMUTER AND ON DEMAND OPERATIONS AND RULES GOVERNING PERSONS ON BOARD SUCH AIRCRAFT
14 CFR 91.417(b)(2)
State that the record of the current status of applicable AD including, for each, the method of compliance, the AD number, and revision date be retained and transferred with the aircraft at the time the aircraft is sold.
14 CFR Part 1
Defines maintenance as inspection, over-haul, repair, presevation, and the replacement of parts, but exludes preventive maintenance.
14 CFR Part 65.18(b)
States that no person who cheats, give or reveives help from another, takes a part of the test for another, uses unauthorized material during the test is eligible for many airman or ground instuctor certificate or rating for a period of one year after the date of that act. in addition, the commission of the act is a basis for suspending or revoking any airman or ground instructor certificate held by that person.
