CASS support

Support for your CASS program.

A Continuing Analysis and Surveillance System (CASS) is an operator's system for continuously analyzing and monitoring the performance and effectiveness of its inspection and maintenance programs, and for correcting any deficiencies in them. We support the analysis and reporting behind CASS programs for Part 121 and Part 135 certificate holders.

14 CFR 121.373

The CASS requirement for Part 121 certificate holders.

The CASS requirement for Part 135 certificate holders whose aircraft are maintained under §135.411(a)(2).
