 ✈️ Repetitive Defects – A Small Change in CAR, A Big Shift in Maintenance Thinking The latest revision of CAR (Section 2, Series C, Part I – Feb 2026) by the Directorate General of Civil Aviation (DGCA), India brings sharper clarity on Repetitive Defects —and it’s more impactful than it may first appear. 🔍 What’s new? A defect is now considered repetitive if it occurs: ➡️ 3 times within 15 flight cycles ➡️ Despite rectification attempts But here’s the real game changer 👇 📡 Even if the defect is NOT reported by the crew… If it is recorded in systems like: Aircraft Health Monitoring (AHM) OEM platforms (e.g., Airbus World) 👉 It MUST still be treated as a reported defect . ⚠️ Why this matters This shifts maintenance from: ❌ Reactive (fix what is reported) ➡️ To ✅ Data-driven (analyze what the aircraft is telling you) Repetitive defects are no longer just technical issues—they are: ✔️ Reliability indicators ✔️ Early warning signals ✔️ Potential safety risks 🛠️ Operational Impact...

  DGCA invited comments for draft CAR – CAMO, which is going to be introduced in near future. Through this CAR a management system of CAMOs, including safety risk management for Organisations that manage the continuing airworthiness of aircraft used by AOC/NSOP holders or conducting operations of large or turbojet aeroplanes for general aviation, should be introduced. That management system should apply to all CAMOs that manage the continuing airworthiness. The organisation may document its safety policy, safety objectives and all its key management system processes in a separate manual (e.g. Safety Management Manual or Management System Manual) or in its CAME (, Part 2 ‘Management system procedures’). Organisations that hold multiple organisation certificates within the scope of relevant Regulation may prefer to use a separate manual in order to avoid duplication. That manual or the CAME, depending on the case, should be the key instrument for communicating the approach to t...

                      Rule 29D of the Aircraft Rules, 1937 requires the service providers to implement a SMS, which is acceptable to the State.  CAR Section 1 Series C Part I prescribes the detailed requirements for establishing SMS and its phased-wise implementation.  CAR Section 1 Series C Part I  prescribes the guidance on contents of the SMS Manual.   SSP Circular No. 02 of 2018  provides the detailed guidance for preparation of SMSM by the service providers.       Guidance for Safety Management System  Manual       SMSM Chapter 1

Those who attend workshop will understand the theory, principles and application of an SMS as well as ICAO requirements for implementation and DGCA guidance for operators and organizati...

            Controlled rests are used by pilots in different countries to combat fatigue on long-haul sectors. And what exactly does "controlled rest" mean?   sleeping. "Sleeping always tends to be talked about in terms of a euphemism, like controlled rest, because people feel much more comfortable with that language."             Fatigue Risk Management System (FRMS) guidelines agreed by the International Air Transport Association (IATA), the International Civil Aviation Organization (ICAO) and the International Federation of Airline Pilots' Associations (IFALPA), controlled rest is recommended on the flight deck for a commercial aircraft, but it's not really defined. It does state "it is not a substitute for pre-flight sleep or for normal crew augmentation, but intended as a response to unexpected fatigue experienced during operations."           Vagueness of what controlled res...

  Essential prerequisites for a successful Safety Management System   1 . comprehensive corporate approach                       An effective SMS will provide a means of achieving enhanced safety performance which meets or exceeds basic compliance with the regulatory requirements associated with safety and quality. It is a well established fact that enhanced safety performance is founded upon a proactive safety culture inherent in all the organisation’s safety related activities. It is achieved by effective, devolved executive management in association with a means of independent safety oversight, both of which are the ultimate responsibility of the organisation’s Board and Chief Executive Officer. The Board and CEO are then able to demonstrate how safety is managed in the company. A corporate approach to safety must be able to meet the following criteria: • Published safety accountabilities of managers and key ...

                   Culture is characterized by the beliefs, values, biases and their resultant behaviour that are shared among members of a society, group or organization. An understanding of these cultural components, and the interactions among them, is important to safety management. Among the most influential cultural components are organizational, professional, and national. A reporting culture is key component of these different cultures. The mix of cultural components may vary greatly among organizations and can negatively influence effective hazard reporting, collaborative root cause analysis, and acceptable risk mitigation. Continous improvement in safety performance is possible when safety becomes a value within an organization as well as a priority at the national or professional level .                         Safety culture encompasses the commonly held perceptions...

  ‘Significant Seven’ safety risks were identified following analysis of global fatal accidents and high-risk occurrences involving large UK commercial air transport aeroplanes by CAA.                                                         Action Plan by CAA Loss of control: Through improved flight control monitoring, use of aircraft automation and manual flying skills CAA are aiming to reduce the risk of loss of control occurrences. Runway Excursion: To help reduce the risk of runway excursions, CAA are aiming to reduce unstable/de-stabilised approaches, improve information broadcast to pilots on expected braking action on contaminated runways and improve safety areas around runways. Controlled Flight into Terrain: CAA are working to reduce the risk of serious incidents that occur during non-precision approaches (NPA...

Base Maintenance Operations and Hazards Maintenance hangars are very large structures capable of accommodating numerous aircraft. The largest hangars can simultaneously accommodate several wide-body aircraft, such as the Boeing 747. Separate work areas, or bays, are assigned to each aircraft undergoing maintenance. Specialized shops for the repair and refitting of components are associated with the hangars. Shop areas typically include sheet metal, interiors, hydraulics, plastics, wheels and brakes, electrical and avionics and emergency equipment. Separate welding areas, paint shops and non-destructive testing areas may be established. Parts-cleaning operations are likely to be found throughout the facility. Paint hangars with high ventilation rates for workplace air contaminant controls and environmental pollution protection should be available if painting or paint stripping is to be performed. Paint strippers often contain methylene chloride and corrosives, including hydr...

                          Maintenance work is divided between that which is necessary to maintain ongoing daily operations (line maintenance) and those procedures that periodically check, maintain and refurbish the aircraft (base maintenance).                 Line maintenance comprises en route (between landing and takeoff) and overnight maintenance. En route maintenance consists of operational checks and flight-essential repairs to address discrepancies noted during flight. These repairs are typically minor, such as replacing warning lights, tyres and avionic components, but may be as extensive as replacing an engine. Overnight maintenance is more extensive and includes making any repairs deferred during the day’s flights.                             The timing, distribution and nature of aircraft mainte...

                   Introduction: ICAO requires ‘States to, as part of their safety programme, have the service providers/ organizations engaged in commercial operations, maintenance of aircraft, aerodrome operations, provision of air traffic services, design organizations, training to implement a safety management system which is acceptable to the State’.                     In compliance with the standards of ICAO Annexes, various CARs specify the requirements for the establishment of SMS by an organisation. SMS CAR- CAR Section 1 General Series C Part I specifies the minimum acceptable requirements for the establishment of SMS in an organization.             Benefits :  To improve on existing levels of aviation safety in the light of the continuing growth of the industry, additional measures are needed. One such measure is to encourage individual...

Hydraulic fluid injection injuries     — planning and prevention                Description: Hydraulic fluid injection injuries can result in tissue damage, amputation, and death. Advance planning for prevention and treatment is critical. Should an injury occur, there is no time for prep — it has already passed.                Fluids in high-pressure applications can escape from pinhole leaks in hoses caused by a number of factors including: age, incompatible fluids, hose twist, and minimum bend radius violations. These pressurized fluids travel at bullet speed and can penetrate deep under the skin. Yet, the injured person may feel only a slight pricking sensation. Rarely does the initial pain indicate injury severity. What looks like a simple puncture wound is life threatening? Hydraulic fluids contain a wide range of chemical compounds that are highly toxic within the bloodstream.   ...
