AIRCRAFT COMPONENTS AND PARTS SUPPLIED BY ROTOR MAXX SUPPORT LTD.

PURPOSE:

This advisory deals with parts and components certified as new, overhauled, or repaired by Rotor Maxx Support Ltd. Approved Maintenance Organization (AMO) # 86-06 (“Rotor Maxx”) between June 15, 2011 and April 22, 2014.

BACKGROUND:

The Canadian Aviation Regulations (CARs) require that parts conform to their type design to be eligible for installation on civil aviation aeronautical products. It also must be determined that new parts were manufactured by a manufacturer certificate holder approved under CAR 561, or equivalent and that they are airworthy. This is normally accomplished by the issuance of a statement of conformity by the manufacturer that accompanies the part.

When used parts are maintained and certified, the previous installation of the part is used as evidence that the part met the requirements for a new part at some previous time. Therefore, only the airworthiness of the used parts needs to be ascertained. The parts are assumed to have been manufactured by an organization authorized to do so and to have met their type design because of their previous installation. These assumptions are based on the fact that the only way a part could have been installed originally was in accordance with the new part requirements.

AMO approved manuals may contain procedures to assess and certify parts that no longer have evidence of certification from a manufacturer or that there is no traceability to a previous installation. AMOs use a variety of resources and data to determine that such a part was indeed manufactured by an organization holding a manufacturer certificate in accordance with CAR 561. Once a determination had been made that the part conforms to its design data, the ICAs (Instructions for Continued Airworthiness) are to be used to ensure the part conforms from a wear perspective as the part was undocumented. Once these activities are complete, the maintenance organization can certify the part.

Rotor Maxx Support Ltd., AMO # 86-06 certified undocumented parts during the period between June 15, 2011 and April 22, 2014. Transport Canada Civil Aviation (TCCA) has found that Rotor Maxx Support Ltd. did not consistently determine that the parts they were certifying for installation on components or parts that were for sale met their approved type design.

RECOMMENDED ACTION:

Aircraft owners, operators, maintenance organizations, parts suppliers, parts distributors, and related personnel should inspect their aircraft, aircraft records, and parts inventories for any parts certified by Rotor Maxx Support Ltd. AMO # 86-06 between June 15, 2011 and April 22, 2014. If you find any of these parts installed on aircraft, you should take appropriate action to verify the airworthiness of the parts or remove them from service. If these parts are located in an existing inventory, it is recommended that these parts be quarantined to prevent installation until a determination can be made as to their airworthiness.
