AC 43.13-1B and 2B
For large aircraft over 12,500 lbs. is there anything preventing the use of the following documents in the absence of specifics called out in the manufactures maintenance manuals?
"Acceptable Methods, Techniques, and Practices - Aircraft Repairs and Inspections" or AC 43.13-2B
"Acceptable Methods, Techniques, and Practices - Aircraft Alterations" ANSWER:
There is nothing to prevent you from using those documents as a reference. AC 43.13-1B says:
"This advisory circular (AC) pertains to aircraft repairs and inspections. The repair data in this AC is for minor repairs to non-pressurized areas of an aircraft. This data can be used if there is no repair or maintenance instructions published by the manufacturer for a needed repair.
The aircraft repairs and inspections outlined here may be used as approved data, and the AC chapter, page, and paragraph listed in block 8 of the FAA Form 337 when:
a. the user has determined that it is appropriate to the product being repaired;
b. it is directly applicable to the repair being made; and
c. it is not contrary to manufacturers data.
* The data here may also be used as a basis
for FAA approval for major aircraft repairs.
FAR 43.13(a) states that each person performing maintenance, alterations, or preventive maintenance on an aircraft, engine, propeller, or appliance shall use the methods, techniques, and practices prescribed in the current manufacturers maintenance manual or Instructions for Continued Airworthiness prepared by its manufacturer, or other methods, techniques, or practices acceptable to the FAA.
The methods, techniques, and practices outlined in this advisory circular are considered acceptable to the FAA."Does it matter if the aircraft is operated under 121 or 135 and maintained under a Continuous Airworthiness Maintenance Program (CAMP)?ANSWER:
No, but I would first refer to the manufacturers Standard Operating Practices Manual (SOPM) for the aircraft in question (if one exists), then if nothing is referenced, use AC 43.13-1B or 2B as a reference. You should also check with your FAA representative to see if he/she would want you to make reference to the use of these AC's in your company maintenance manual.NOTE:
We have put both AC 43.13-1B and AC 43.13-2B online at our Aviation Safety Bureau website
for easy reference. It's FREE to access these documents, but you must first register.
