DGCA Updates Aircraft Engine Inspection Protocols: What the New Safety Rules Mean
Aircraft engine safety has now become the focal point of discussion in the country’s aviation safety debate, with the Directorate General of Civil Aviation (DGCA) introducing stricter measures to enforce inspection, airworthiness, and technical surveillance. This has been made all the more crucial after several cases of failure in aircraft systems and engines, with the recent engine parts scrutiny in the wake of the Air India AI171 incident.
The recent drive towards safety is not about asking the airlines to ‘inspect engines more frequently’. Aircraft maintenance already involves specific inspection schedules, manufacturer manuals, airworthiness directives and mandated services. The key is to ensure that the process follows its due course. According to the DGCA publications itself, engine and aircraft inspections, mandatory modifications and airworthiness surveillance form part of the safety regime in India.
What Has Changed in Aircraft Engine Inspections?
However, the critical difference is the increased attention to verification and compliance of airlines rather than the introduction of an entirely different inspection procedure that would replace the existing ones. The airlines are obliged to carry out the maintenance programs approved by the DGCA, and the DGCA, in turn, carries out its surveillance and may order additional inspections when a technical problem arises.
One of the recent cases was initiated when a pilot of Air India pointed out the potential problem associated with the engine fuel-control switch of a Boeing 787. As a result, Air India started conducting precautionary inspections of the corresponding switches of its fleet, and the problem was passed to the Boeing Company. DGCA had already ordered the inspections of fuel-control switches of Boeing planes in India in light of the Ahmedabad accident.
Why Engine Checks Matter So Much
These parts are subjected to very high temperatures and mechanical stresses. The failure of even a relatively small part will lead to serious consequences, especially if the problem affects the aircraft fuel system, engine controls, engine combustion process, etc.
Engine maintenance cannot be considered just a regular car repair. Engineers use inspection schedules, maintenance manuals issued by the engine manufacturer, airworthiness directives and technical documentation to establish what should be checked, replaced or controlled.
According to DGCA reports, engine maintenance can include checking the engine condition during inspections (e.g., borescope examination). For instance, in one of the DGCA investigations, the compressor and turbine parts were checked during an engine inspection and borescope examination.
What Does This Mean for Airlines?
Inspection oversight is a key factor in focusing on the proof of completion of the maintenance tasks in a timely manner. Appropriate maintenance records need to be kept, airworthiness directives must be followed, along with mandatory modifications and releases to service should be made only after all required inspections are done.
This task becomes even more challenging if there is a persistent technical problem with the aircraft. Instead of following regular maintenance routines, more inspections might need to be conducted or specific recommendations from the manufacturer and the regulatory agency might need to be considered.
It is clear what the aim of the whole process is: detect any problems while the aircraft is on the ground and not during the flight.

What Role Does DGCA Play?
DGCA is the main body that regulates civil aviation in India and its responsibility is to regulate airworthiness and operational safety. The Directorate of Airworthiness in particular is an important body for checking whether the aircraft and the maintenance organization meet the required standards.
The surveillance regime set out by DGCA in their reports involves inspections and audit of aircraft, maintenance organizations and aviation operations. It is noted that there is extensive technical supervision involving cockpit and flight data recorder information, type approval of aircraft and engines and modification approvals.
The regulator can also impose penalties in case of non-compliance which may involve penalties for the approvals, certificates or licenses depending on the gravity of the violation.
Why the AI171 Crash Changed the Safety Conversation
There is no doubt that the Air India AI171 accident that occurred in June 2025 is a crucial incident in Indian aviation-safety discourse. According to preliminary findings, the turning of the fuel control switch from RUN to CUTOFF of both engines in the moments immediately after takeoff was considered a significant incident, though the investigation did not confirm any intentionality of such actions by pilots.
This case highlighted the need for proper inspection of cockpit controls, engines, fuel systems and the importance of compliance with recommendations on safety measures.
A similar problem with a fuel control switch in another Air India Boeing 787 showed why such inspections could be necessary in certain cases even if the particular component was not identified as defective for the whole aircraft fleet.
Does This Mean Flying Is Becoming Less Safe?
No, it does not mean that. Actually, multiple inspections are evidence of proactive approach of the safety system towards existing threats.
In any case, commercial flights undergo several safety procedures before their departure from the airports. These include maintenance inspections performed by engineers, control of performance by airlines, service instructions and airworthiness directives issued by manufacturers.
However, a more essential point here is the proper interaction of these measures. Recently there were some reports regarding understaffing at the airworthiness department of DGCA, underlining the significance of adequate personnel to carry out inspections and surveillance.
In other words, well-defined protocols are efficient only if there are sufficient resources and systems in order to follow them.
What Does It Mean for Passengers?
As far as the passengers are concerned, all these technicalities may seem confusing; however, the main message can be easily understood by everyone. In case a new inspection process or precautionary check is introduced, this does not necessarily imply the unsafety of the aircraft.
The fact that an airline company grounds an aircraft or performs additional technical inspections means that it prevents any potential problem from being faced by passengers. The release of the aircraft into operation is done only after meeting all the necessary maintenance requirements.
Thus, passengers should not treat every such announcement as a sign that the process of flying has become dangerous for their health.
What Happens When an Engine Problem Is Found?
In case a defect is found during inspection, the engineers evaluate it based on accepted maintenance information and decide if it will allow the airplane to continue its work, if it needs repairing or it must stay grounded.
Sometimes it could be something that is possible to replace fairly quickly. In other situations, further inspection or special maintenance could be required by the aircraft before it is ready to fly.
Modern airplane engines are constantly checked based on their technical indicators and supported by manufacturers’ services. There are examples from the DGCA investigation report where performance trends of engines and notifications from the manufacturers helped in identifying developing problems.
The Bigger Safety Lesson
The latest trend in inspections of aircraft engines confirms another important principle of modern aviation – there is no safety ensured by one inspection and one body. Safety should be guaranteed by a chain of activities that includes manufacturers, airlines, maintenance engineers, pilots, and regulators.
A technologically advanced aircraft cannot be considered safe in terms of the system of maintaining, monitoring and certification of the aircraft.
This is what makes the DGCA’s new focus on compliance and surveillance regarding inspections so important. The idea is not only to detect defects after an accident or malfunctioning, but to detect warnings in time and ensure correct action taken.
Conclusion
DGCA’s changing attitude towards aircraft and engine safety is part of a general attempt at increasing oversight following a number of notable aviation accidents and technical problems. Increasing the focus on proper inspections, guidance of manufacturers, compliance and documentation is the current direction of regulatory measures.
For passengers, this is reassuring, but also very important information – additional inspections are needed in order to avoid potential problems. At the same time, the effectiveness of the measures depends upon proper maintenance performed by airlines and adequate technical capacity of the regulators.
New safety emphasis is not about establishing a sweeping “engine rule” but instead about tightening up India’s present aircraft maintenance and airworthiness process. The end result for passengers is increased scrutiny of the planes prior to their being deemed fit for flight.
