The DGCA has proposed updates to its CAR-145 maintenance rules to include electric engines, introducing dedicated 'B4' and 'C23' categories for new aviation technologies. This regulatory shift aims to standardize safety for electric and innovative aircraft designs in India. The proposed changes signal an effort to prepare the local aviation ecosystem for upcoming advancements in electric propulsion and aerial mobility, with feedback open until November 1.
The Directorate General of Civil Aviation (DGCA) has drafted amendments to its Civil Aviation Requirements (CAR-145) to create a formal maintenance framework for electric aircraft engines. This move effectively modernizes India’s aviation safety regulations to account for the transition from traditional internal combustion and turbine engines to electric propulsion systems.
Establishing Dedicated Maintenance Categories
The proposal introduces a new 'B4' engine category specifically for electric propulsion. Previously, electric engines were categorized under general electrical components, which limited the scope for specialized maintenance. By establishing a dedicated B4 category, the regulator is creating a pathway for Maintenance, Repair, and Overhaul (MRO) organizations to receive specific certification for handling high-voltage systems, electric rotors, and battery-driven propulsion.
In addition to the engine category, the DGCA is proposing a 'C23' category for advanced aviation components. This classification is intended to cover innovative equipment and experimental systems that do not fit into existing technical chapters. For India’s growing MRO sector, these defined categories provide a clearer regulatory roadmap, allowing specialized firms to invest in tooling and training for next-generation aircraft technology with greater legal clarity.
Data Sharing and Safety Protocols
The regulatory update also focuses on strengthening the communication loop between maintenance providers and design approval holders. Under the proposed guidelines, MRO providers would be required to share reports on technical occurrences directly with the original manufacturers. This mandatory reporting is intended to reduce the reliance on ad-hoc or improvised field repairs, ensuring that any anomalies are addressed through factory-backed service instructions.
For aviation stakeholders, this regulatory focus on manufacturer-backed solutions implies higher quality standards, though it may also increase compliance requirements for MRO service providers. Organizations operating in India will likely need to adjust their internal protocols to align with these data-sharing mandates if the draft is finalized.
What Investors Should Monitor
The DGCA has invited feedback on these proposals until November 1, 2026. For investors, the development underscores the government's intent to build the regulatory foundation for electric aviation in India. The key monitorable will be how quickly Indian MRO firms adapt their facilities and certification processes to meet these standards. As the ecosystem for electric aerial vehicles develops, the ability of maintenance companies to secure B4-level certifications will likely differentiate the market leaders in the emerging electric aviation support industry.
