42 b. The DAAO Inspector should exercise discretion when using the
term “representative number,” as this will vary with the type of application and the depth and complexity of the work performed.
c. An applicant would normally receive an airframe Class 4 rating after demonstrating the ability to maintain one of each make in that
class i.e., Boeing 747, Airbus A300, or MD-11. d. An accessory, radio, instrument, etc., class rating would differ from
the airframe rating because of the various makesmodels of valves, radios, instruments, and other articles that are very similar in
design and function.
e. The issuance of a class rating would be at the discretion of the applicant and agreeable to the DAAO Inspector when the applicant
has demonstrated the capability to maintain several different articles.
f. When a AMO with managerial control is issued a class rating, CASR Part 145.107a1 is not intended to preclude the satellite
from holding an associated limited rating. For example, it is acceptable for the AMO with managerial control to hold an airframe
Class 4 rating, while the associated satellite holds a limited airframe rating.
i. The list, by make, of the propeller for a Class 2 propeller rating. ii. A copy of the acceptableapproved specification for the work to
be performed for a specialized service rating, when applicable. iii. A copy of a capability list, if appropriate CASR Part 145.215.
c. Document Deficiencies. If any document has deficiencies, return it to the
applicant with a letter outlining the deficient areas. Inform the applicant that the certification process will not continue until all deficiencies are
resolved.
5. DEMONSTRATION AND INSPECTION PHASE.
During the demonstration and inspection phase, the CPM should verify that the AMO meets the requirements of CASR Part 145.51b.
Although the AMO is allowed to contract a maintenance function to an outside source, the CPM must verify that the AMO is capable of performing the
maintenance under the rating requested.
Contracted maintenance functions must not circumvent the certification requirements. Unless the DAAO indicates otherwise, personnel and
equipment from the certificated AMO with managerial control and from each of the satellite AMOs may be shared in accordance with CASR Part
July 2013
43 145.107b. Shared personnel must be qualified and familiar with any
procedural differences at each assigned location.
a. Coordinate and Schedule Inspection. Coordination is required between
the CPM, team members, and the applicant. 1 During the inspection phase, the team should verify that the AMO
manual and the QCM are followed. 2 The team should also use the AMO letter of compliance to confirm that
the facility meets all the requirements of the regulations.
b. Perform a Housing and Facility Inspection. During the demonstration
and inspection phase, inspect the AMO facilities to ensure that the work performed has protection from weather elements, dust, and heat. Ensure
that the control of temperature, humidity, and other climatic conditions allow personnel to perform maintenance functions to the standards
required by this staff instruction. In addition, inspect for the following:
1 Tooling and equipment are properly stored and maintained in good working order:
a Calibration is performed at established intervals and meets the requirements of CASR Part 145.109.
b If the AMO obtains special equipment and tools as needed in accordance with CASR Part 145.109, verify that a contract is
available for review to ensure that the tools and equipment will be available upon the AMO’s request.
NOTE: All tools and equipment must be in place at the time of initial certification or rating approval by the DAAO CASR Part 145.51b.
2 Material. Ensure that all materials needed for the rating are on the premises and under the AMO’s control during work performance.
a Ensure that the AMO has the proper controls for stored material and a recordkeeping system that has document traceability back to
the place of purchase. b Traceability of all materials in the supply room must have
documentation to show the material qualification e.g., invoice, process specifications, and supplier qualifications.
c If necessary, a AMO surveillance program of its suppliers to meet the above will meet these requirements.
