IAF's AN-32 fleet allowed to use blended aviation fuel

Date: 25 May 2019 Tags: Defence & Security

The Russian origin AN-32 aircraft of Indian Air Force (IAF) were formally fleet certified to fly on blended aviation fuel, containing up to 10indigenous bio-jet fuel. The approval certificate was received from Centre for Military Airworthiness and Certification (CEMILAC).

This bio-aviation fuel is made from Jatropha oil sourced from Chattisgarh Biodiesel Development Authority (CBDA) and then processed at CSIR-Indian Institute of Petroleum (CSIR-IIP), Dehradun.

The recent certification is huge step in promoting ‘Make in India’ mission as this bio-fuel will be produced from Tree Borne Oils (TBOs) sourced from tribal areas and farmers, augmenting their income substantially.

Background

The indigenous bio-jet fuel was first produced by CSIR-IIP lab at Dehradun, Uttarakhand in 2013, but could not be tested or certified for commercial use on aircraft due to lack of test facilities in the civil aviation sector. 

In July, 2018, Chief of Air Staff Air formally had announced IAF’s intention to permit use of all its resources for testing and certifying the indigenous fuel. Since then, IAF has undertaken series of tests for evaluating the performance of this fuel against international standards.
