STANDARD OPERATING PROCEDURE (SOP)

Annual Maintenance Contract (AMC) and Comprehensive Maintenance Contract (CMC)

SOP No. ENG/QC/SOP/___ Effective Date ___
Revision No. 00 Department Engineering / Quality Control

1. Purpose

To establish a controlled and systematic procedure for planning, execution, monitoring, and review of Annual Maintenance Contracts (AMC) and Comprehensive Maintenance Contracts (CMC) for laboratory instruments and equipment to ensure consistent performance, regulatory compliance, and minimization of breakdowns.

2. Scope

This SOP applies to all GMP-critical and non-critical laboratory instruments and equipment covered under AMC or CMC agreements in Quality Control, Quality Assurance, Engineering, and related departments.

3. Definitions

AMC (Annual Maintenance Contract): A contract covering preventive maintenance and limited corrective services excluding major spare parts.

CMC (Comprehensive Maintenance Contract): A contract covering preventive maintenance, corrective maintenance, labor, and spare parts.

4. Responsibilities

  • Engineering Head: Overall control of AMC/CMC program.
  • QC / User Department: Reporting issues and verifying equipment performance.
  • Service Provider: Timely execution of maintenance activities.
  • Quality Assurance: Oversight, compliance verification, and audit support.

5. Detailed Procedure

5.1 Identification of Equipment for AMC / CMC

The Engineering Department shall prepare and maintain a list of laboratory instruments requiring AMC or CMC based on equipment criticality, usage frequency, complexity, and regulatory impact. GMP-critical instruments shall be prioritized.

5.2 Selection of Service Provider

Approved and qualified service providers shall be selected based on technical competence, OEM authorization (where applicable), service capability, and past performance. Vendor qualification records shall be maintained.

5.3 Finalization of AMC / CMC Agreement

The AMC/CMC agreement shall clearly define scope of services, frequency of preventive maintenance, response time, breakdown support, spare parts coverage, documentation requirements, and contract duration. Agreements shall be approved by Engineering Head and QA.

5.4 Scheduling of Preventive Maintenance

Preventive maintenance schedules shall be prepared at the beginning of the contract period. Maintenance activities shall be planned to avoid impact on laboratory operations. The user department shall be informed in advance.

5.5 Execution of Preventive Maintenance

Preventive maintenance shall be carried out as per the approved schedule and OEM recommendations. Activities may include cleaning, lubrication, inspection, calibration verification, software checks, and functional testing. All activities shall be documented in equipment logs.

5.6 Breakdown Maintenance

In case of equipment failure, the user department shall inform Engineering. Service requests shall be logged and attended as per defined response time. Root cause shall be identified, corrective action taken, and documented.

5.7 Acceptance Criteria After Maintenance

  • Equipment operates without error or alarm
  • System suitability meets method requirements
  • Calibration status remains valid
  • No adverse impact on analytical results

5.8 Review and Performance Evaluation

Engineering and QA shall periodically review service provider performance based on response time, effectiveness of repairs, repeat failures, and documentation quality. Unsatisfactory performance shall trigger corrective actions.

5.9 Renewal or Termination of AMC / CMC

Before contract expiry, performance shall be reviewed to decide renewal, modification, or termination. Renewal shall be based on equipment condition, service quality, and regulatory requirements.

6. Documentation and Records

  • AMC / CMC agreements
  • Preventive maintenance schedules
  • Service reports
  • Equipment logbooks
  • Vendor qualification records

7. Compliance and Data Integrity

All maintenance activities and records shall comply with Good Documentation Practices. Records shall be contemporaneous, accurate, and traceable.
