NOTE 2: A combination of storing equipment, tools, parts, etc., and having AMO personnel permanently positioned at a site and performing
maintenance on a daily basis away from its permanent fixed base indicates a continuous, uninterrupted operation. An AMO that operates in
this fashion no longer meets the intent of CASR Part 145.203. If the AMO is to continue its operations in this manner, then it must apply for
certification as a satellite or stand-alone AMO.
d. Permanent Fixed Location. Additionally, work that is to be performed at another
location does not include other authorizations, such as having a line maintenance authorization to perform work for an air carrier. Work performed at locations away
from their fixed base allows AMOs the flexibility to meet industry needs and to be mobile when necessary. AMOs must still maintain a permanent fixed location
even if the majority of their work is done at another facility.
6. MAINTENANCE,
PREVENTIVE MAINTENANCE,
AND ALTERATIONS
PERFORMED FOR AIR CARRIERS UNDER PARTS 121, 129, AND 135. a. Reference.
CASR Part 145.205.
b. Requirements.
Some AMOs perform maintenance, preventive maintenance, or alterations for air carriers conducting operations under parts 121, 129, and 135.
In this case, this section of the manual must describe the procedures to ensure that maintenance is performed in accordance with the air carrier’s program and
maintenance manual. These procedures must ensure that the air carrier has provided the AMO with the information necessary to ensure compliance with this
requirement. The air carrier may provide the AMO with the applicable sections of its maintenance program or manuals at the time the work is performed. On the
other hand, the purchase order or other contractual documents from the air carrier could clearly state the source of the data manufacturer’s or air carrier’s
manual used to perform the requested maintenance along with any other requirements of its program or maintenance manual. Again, the operator may
provide the AMO with the applicable sections of its inspection program or clearly outline the requirements on the purchase order.
c. Identify Responsibilities. The procedures should identify who is responsible by
title for keeping all of the operators’ data current, and where these manualssections will be located if retained at the AMO. The procedures also
must explain what air carrier or commercial operator information must be available to maintenance personnel when the work is performed. Additional
procedures will be required to ensure that purchase orders are thoroughly reviewed. This review will be necessary to ensure that the air carrier has clearly
specified what technical data to use for performing the maintenance. Employees may need additional training to properly perform this review. The traveler or
work-order system of the AMO may be used to integrate this information into the quality control system. If the AMO transfers requirements from the air carrier or
commercial operator to its maintenance personnel by special instructions on the
