Maintenance Technician and Inspection Authorization

Inspection Task

• Review of the Inspection tasks will assist you in performing the task of a maintenance technician and Inspection Authorization to the requirements of the Federal Aviation Regulations

• Recurrent training is the key to your success and the key to maintaining a safe aircraft.

• Lets take a look at those tasks that we are required to do as a maintenance technician.

INSPECTIONS

III-4

Inspections are the most important task that we perform. It is also important that we build a working relationship with the owner and operator aircraft so we can complete the requirements ofthe inspection to determine that all the airworthiness requirements are met.

It is just as important that the owner/operator understand their responsibility in maintaining the aircraft . Take the opportunity to explain the requirements of the regulations and assist the owner/operator in making sure that all the requirements of the regulation are met.

III-5

CUSTOMER RELATIONS... GET IT STRAIGHT

III-6

Explain to the customer the requirement of the inspection and what it is going to take to accomplishthe entire inspection. Remember maintenance includes inspection and items found during the inspection must have a corrective action.

III-7

Many times there is a misunderstanding that the owner/operator has an option not to fix discrepancies found during the inspection. The regulation does not allow items to be deferred except in accordance with inoperative equipment procedures. Therefore, once you have determined it to be a discrepancy, a corrective action must be taken. Set it straight before you start the inspection.

3. AIRCRAFT SERIAL NUMBER 4. CATEGORY

5. AUTHORITY AND BASIS FOR ISSUANCE

This airworthiness certificate is issued pursuant to the Federal aviation Act of 1958 and certifies that, as of the date of issuance, theaircraft to which issued has been inspected and found to conform to the type certificate therefor, to be in a condition for safe operation, and had been shown to meet the requirements of the applicable comprehensive and detailed airworthiness code asprovided in Annex 8 to the Convention on International Civil Aviation, except as noted herein.Exceptions:

6. TERM AND CONDITIONS

Unless sooner surrendered, suspended, revoked, or a termination date is otherwise established by the Administrator, thisAIRWORTHINESS certificate is effective as long as the maintenance, preventive maintenance, and ALTERATIONS are performed inaccordance with Parts 21, 43, and 91 of the Federal Aviation Regulations, as appropriate, and the aircraft is registered in the United States.

DATE OF ISSUANCE FAA REPRESENTATIVE DESIGNATION NUMBER

Any alteration, PRODUCTION, or misuse of this certificate may be punishable by a fine not exceeding $1,000 or imprisonment not exceeding 3years or both. THIS CERTIFICATE MUST BE DISPLAYED IN THE AIRCRAFT IN ACCORDANCE WITH APPLICABLE FEDERALAVIATION REGULATIONS.

III-10

The first thing we need to do in our research is to determine the aircraft had been registered and that is has an airworthiness certificate.

FAR 91.203 Civil Aircraft: Certification Requirements.

If these are not present, we must informthe owner/operator of their responsibility.

III-12

Maintenance record research is a time consuming task but is a must. It is important to review the work that may have been accomplished since the last inspection. As part of the inspection you will be taking responsibility for the condition of the item being inspected and you want to make sure the work accomplished meets all the regulation and airworthiness requirements.

If additional equipment is to be installed, it must be done in accordance with the reference drawing, accessory kit instructions, or a separate FAA approval.

NOTE

III-43

A complete equipment list will also assist in the task of accomplishing a weight and balance, Airworthiness Directive review and compliance listing.

If your aircraft does not have a current equipment list it is impossible to know all the equipment make, model and serial numbers of the equipment installed.

III-44

Airworthiness Directives

• Let’s take a look at Airworthiness Directives and the compliance requirements. Guidance and information can be found in AC39-7C Airworthiness Directives

• Airworthiness Directives are mandatory and it is the responsibility of the owner/operator to assure the AD’s are complied with. Additionally, the maintenance technician performing an inspection is responsible to see the AD’s are complied with.

III-45

Airworthiness Directives

• The person performing the compliance of an airworthiness directive is responsible to assure all airworthiness requirements are met.

• Airworthiness Directive research is a must when performing any inspection.
