CAA
U.S. federal law regulating air emissions and quality standards
AS9110C
Aerospace standard for MRO quality management systems.
Quick Verdict
CAA mandates air quality compliance for all industries via emissions standards and permits, enforced by EPA penalties. AS9110C is a voluntary QMS certification for aerospace MROs ensuring safe maintenance. Companies adopt CAA for legal survival, AS9110C for market access.

CAA Details
What It Is
Clean Air Act (CAA), codified at 42 U.S.C. §7401 et seq., is a comprehensive U.S. federal statute governing air pollution from stationary and mobile sources. Its primary purpose is protecting public health and welfare via ambient standards and emission controls. Key approach: cooperative federalism, where EPA sets national floors (NAAQS, NSPS) and states implement through SIPs and permits.
Key Components
- NAAQS for six criteria pollutants (ozone, PM, CO, Pb, SO2, NO2) with primary/secondary levels.
- SIPs, nonattainment planning, NSR/PSD.
- Technology standards: NSPS, NESHAPs/MACT.
- Title V operating permits, Title II mobile sources, Title IV/VI special programs.
- Enforcement via §113 penalties, sanctions. No central certification; compliance via enforceable permits/SIPs.
Why Organizations Use It
Mandatory for emitters to avoid civil/criminal penalties, sanctions, FIPs. Manages risks from nonattainment, permitting delays. Strategic benefits: ESG performance, efficiency via trading, stakeholder trust, operational flexibility.
Implementation Overview
Phased: regulatory gap analysis, emissions inventory, permitting (Title V/NSR), control installs, CEMS monitoring, reporting (CEDRI/ECMPS). Applies to major sources nationwide; ongoing audits, renewals every 5 years.
AS9110C Details
What It Is
AS9110C (Quality Management Systems Requirements for Aviation Maintenance Organizations) is a certification standard derived from ISO 9001:2015, tailored for Maintenance, Repair, and Overhaul (MRO) organizations. Its primary purpose is to ensure safe, compliant aviation maintenance through risk-based thinking (RBT) and PDCA cycles, addressing aerospace-specific risks like configuration and counterfeit parts.
Key Components
- 10 clauses in ISO High Level Structure (HLS): Context, Leadership, Planning, Support, Operation, Performance Evaluation, Improvement.
- Core areas: configuration management, counterfeit prevention, human factors, traceability, supplier controls.
- Built on ISO 9001 with MRO additions; requires certification via accredited audits demonstrating operational effectiveness.
Why Organizations Use It
- Meets customer/OEM contracts, regulatory alignment (FAA/EASA Part-145).
- Mitigates safety risks, reduces rework/AOG events.
- Enhances market access, efficiency (5-12% labor cost reduction), stakeholder trust.
Implementation Overview
- Phased: gap analysis, process design, pilot, audits, certification (6-12 months typical).
- Applies to MROs globally; involves training, eQMS, internal audits.
