Oversight — how DGCA watches the system
Approvals, licences and certificates are only the start. DGCA must keep verifying that organisations and people continue to comply. The syllabus (10.8) calls this “oversight principles in continuing airworthiness”.
- Rule 156 — the DG or authorised DGCA officers may inspect any aircraft or aviation facility to grant an approval or certificate, and afterwards carry out surveillance, including unannounced inspections.
- Access — every approved organisation must give DGCA-authorised persons access to facilities, aircraft, documents, records and data, including at subcontractors (145.A.140, CAMO.A.140). Owners must give DGCA access to their aircraft and records (ML.A.201(g)).
- Oversight planning cycle — the time frame in which DGCA reviews all areas and processes of an approval; the oversight programme is the detailed schedule of audits, inspections and product audits within that cycle.
- DGCA's own procedures (the old CAR-M/CAR-145 “Section B”) are in the Airworthiness Procedures Manual (APM), including aircraft continuing airworthiness monitoring (ACAM) inspections of individual aircraft. Surveillance activity and deficiency reporting are done through the eGCA portal.
- Organisations must also implement DGCA safety measures and mandatory safety information immediately (145.A.155).
Findings — Level 1 and Level 2
| Level | Definition | Response |
|---|---|---|
| Level 1 | Significant non-compliance that lowers the safety standard and seriously endangers flight safety | Immediate attention and rectification; DGCA may limit, suspend or revoke the approval in whole or part |
| Level 2 | Non-compliance that may lower the safety standard and may endanger flight safety | Corrective action within the period agreed with DGCA |
| Observation | Not a non-compliance, but an item with potential to become one | Organisation considers it and responds |
AAC 2 of 2011 gives examples. Level 1: a system lapse (no audit/quality system); failure to comply with ADs or alert SBs; no control of life-limited parts; aircraft not maintained to the approved programme; inspection items not signed but CRS issued; ALIs/CMRs not in the AMP; uncalibrated tools; no production planning leading to a maintenance failure; all post holders missing; C of A or ARC missing on board. Level 2: a procedural lapse (e.g. audits missed on two occasions), a procedure not documented, one post holder missing.
After receiving findings, the organisation (145.A.95, M.A.902) must identify the root cause and contributing factors, define a corrective action plan including action to prevent recurrence, and demonstrate implementation to DGCA's satisfaction within the agreed period.
A missing procedure is typically Level 2; not doing the safety-critical thing (not complying with an AD, uncalibrated tools, no control of life-limited parts) is Level 1.
Enforcement
- DGCA may suspend, cancel, limit or endorse approvals, licences and certificates, or issue warnings and admonitions (Rules 19, 61, 133B(10)).
- The Bharatiya Vayuyan Adhiniyam 2024 provides prosecution (up to 2 years and/or ₹1 crore), compounding and civil penalties adjudicated by designated officers, with appeals (Chapter 1).
- The DGCA Enforcement Policy and Procedures Manual guides proportionate action — and a just culture does not protect gross negligence or wilful violations.
State Safety Programme and SMS
ICAO Annex 19 requires each State to have a State Safety Programme (SSP) and service providers to have a Safety Management System (SMS). In India: Rule 29C — the DG formulates the SSP; Rule 29D — operators, large/turbojet GA operators, aerodromes, design, manufacturing and maintenance organisations, FTOs and ATS providers must have an SMS and SMS manual accepted by DGCA; CAR Section 1 Series C Part I (Issue III, 24 March 2022) gives the framework.
Four components, twelve elements
| Component | Elements |
|---|---|
| 1. Safety policy and objectives | Management commitment · Safety accountability and responsibilities · Appointment of key safety personnel · Coordination of emergency response planning · SMS documentation |
| 2. Safety risk management | Hazard identification · Safety risk assessment and mitigation |
| 3. Safety assurance | Safety performance monitoring and measurement · Management of change · Continuous improvement of the SMS |
| 4. Safety promotion | Training and education · Safety communication |
- Accountable executive — a single, identifiable person responsible for the effective performance of the SMS.
- Safety manager — appointed to implement and maintain the SMS; manages the implementation plan, safety training, hazard identification and risk analysis, monitors corrective actions, reports safety performance; details submitted to DGCA for acceptance. If a group shares the role, a lead safety manager reports directly to the accountable executive.
- Safety performance indicators (SPIs) and targets measure performance; management of change assesses hazards before changes are implemented.
- Just culture — personnel are not punished for actions, omissions or decisions commensurate with their experience and training, but gross negligence, wilful violations and destructive acts are not tolerated.
CAR-145 Issue 3 and CAR-CAMO embed these elements in the organisation's management system (145.A.200) with an internal safety reporting scheme (145.A.202).
Safety reporting — mandatory and voluntary
| Mandatory | Voluntary | |
|---|---|---|
| Legal basis | Rule 29E — DGCA establishes a mandatory safety reporting system | Rule 29F — non-punitive voluntary safety reporting system; data protected and used only for safety; reporter's identity kept confidential |
| Who / what | Organisations and persons report occurrences listed in CAR Sec 5 Series C Part I and AAC 2 of 2024 Appendix A | Anyone in aviation reports hazards and deficiencies not captured by mandatory reporting — via eGCA, email or post (AIC 16 of 2021); anonymous reports accepted |
| Deadline | As soon as practicable, within 72 hours of becoming aware | — |
An occurrence is any safety-related event or condition of an aircraft or component that endangers or, if not corrected, could endanger an aircraft (AAC 2 of 2024). Continuing airworthiness reports (M.A.202, 145.A.60, CAMO.A.160) go to DGCA, the design approval holder, and the organisation managing the aircraft's continuing airworthiness. After analysis, organisations send a follow-up report with corrective/preventive actions. Accidents and serious incidents are investigated by the AAIB (BVA 2024 s.7; Aircraft (Investigation of Accidents and Incidents) Rules).
Defect reporting — CAR Section 2 Series C Part I
This CAR implements Rule 59 (report major defects) and Rule 60(5).
- Major defect — a defect of such a nature that it reduces the safety of the aircraft or its occupants (including defects found during an emergency or normal operation or maintenance).
- Repetitive defect — a defect recurring 3 times within 15 flight cycles despite rectification attempts on the same aircraft (including faults stored in maintenance systems even if the crew did not write them up).
- Initial information: major defects, those needing major repair, or serious ones attracting public attention are notified immediately by telephone to the Regional Airworthiness Office, followed by written information within 72 hours (Appendix II format).
- Examples of reportable events: fire or smoke, toxic fumes in the cabin, in-flight engine shutdowns (flameout, external damage, foreign object ingestion or icing, more than one engine), propeller feathering or overspeed control failures, fuel system and structural failures.
- Where maintenance is contracted, the operator remains responsible for reporting; the operator and AMO agree a system documented in the CAME and MOE; the AMO keeps records of defects on the operator's aircraft.
- All defects, including repetitive ones, feed reliability statistics; scheduled operators prepare a monthly fleet performance report (premature removals, in-flight shutdowns and rates, abortive take-offs…) — see AAC 5 of 2001.
- Operators must promptly review defects and the adequacy of rectification using qualified technical staff.
Chapter summary

- SSP (Rule 29C), SMS (Rule 29D, Sec 1 Series C Part I): 4 components / 12 elements; accountable executive; safety manager; just culture.
- Mandatory (Rule 29E, 72 hours) and voluntary non-punitive (Rule 29F, AIC 16 of 2021) reporting.
- Major defects: phone RAO immediately, written report within 72 hours; repetitive defect = 3 times in 15 cycles; monthly reliability statistics.
