Purpose and scope
The purpose of this Certification Memorandum is to supplement the existing guidance for compliance with CS 27/29.602 – Critical Parts, detailing the need for post certification actions to verify the continued integrity of critical parts. These actions should ensure that critical parts are controlled throughout their service life in order to maintain the critical characteristics on which certification is based. In addition, the effectiveness of any associated design, maintenance and monitoring provisions, which either help ensure the continued integrity or provide advance indication of impending failure of critical parts, should be assessed. The CM-S-007 issue 2 has limited the applicability of CIVP to critical parts (compared to issue 1). This is an interim action prior to the publication of the policy related to CIVP that will be defined as part of RMT.0752 where the applicability will be also assessed through an impact assessment.
