File Classification No. : Z 5000-35
RDIMS No. : 15798630
Document No. : CASA 2019-08
Issue No. : 01

This Civil Aviation Safety Alert (CASA) is to alert owners, operators, maintainers and distributors to suspected unapproved parts distributed by Sofly Aviation Services, Inc. of Miami Lakes, Florida, United States of America.


Several service difficulty reports have been submitted to Transport Canada Civil Aviation (TCCA) stating that Sofly Aviation Services, Inc. seems to have distributed parts with falsified Authorized Release Certificates (ARCs).

The falsified ARCs appear to have been, but were not actually, signed by approved manufacturing or maintenance organisations outside of Canada using a Federal Aviation Administration (FAA) 8130-3 or European Aviation Safety Agency (EASA) Form 1. The organisations named on the ARCs deny manufacturing or maintaining the parts in question and deny that the personnel who certified the parts ever worked for their organisations.

A falsified ARC renders the affected part as being unapproved for installation on Canadian registered aircraft in accordance with Subpart 571 of the Canadian Aviation Regulations (CARs) and puts the part’s airworthiness in question.

TCCA is working closely with both the FAA and EASA who are also investigating these reports. Through this cooperation, TCCA has learned that Sofly Aviation Services, Inc. has suspended operations in the United States.

Recommended action:

Aircraft owners, operators, maintainers, and distributors are encouraged to inspect their aircraft and inventories for parts obtained from Sofly Aviation Services, Inc.

If parts are found then the ARC that came with the affected part obtained from Sofly Aviation Services Inc., such as a FAA  8130-3 or EASA Form 1, should be verified to determine whether or not the certification is false. Confirmation from the organisation that issued the certification may be required to ensure that they in fact did manufacture or maintain the part in question and whether the person that certified the part was authorized by the organisation.

If it is determined that an ARC has been falsified then the affected unapproved part should be removed and replaced. Unapproved parts found in inventory should not be sold, distributed or installed on an aeronautical product and should be quarantined as unairworthy parts.

Any person who believes a part was not manufactured or certified in accordance with the applicable regulations of the state of production, is improperly marked, or is documented in such a manner as to mislead, shall submit to Transport Canada a report of the suspected unapproved part via the Web Service Difficulty Reporting System (WSDRS) at:
