Squadron Leader Rangasamudram Kylasam Sekar has been on the posted strength of Area Maintenance Support facility Centre Electronics Standards and Calibration Laboratory since 06 August 1983.

During the mid 1987 period, when the political situation in southern region required availability of full transport aircraft fleet, the IAF was faced with a serious problem of unserviceabiilty of an electronics switching unit BK- 4 used in cockpit warning system of Sutluj aircraft. As a result large number of aircraft were non operational. The factory level repair facilities for this unit were not set up in India till then all unserviceable items were being sent to the manufacturers for repairs.

Sqn Ldr Sekar using his exceptional knowledge of modern electronics developed the detailed repair techniques and fabricated Simulator for functional testing. Thereafter, he started repairing the BK-4 units and within one month repaired all units thereby significantly improving the fleet serviceability.

Sqn Ldr Sekar, after successfully completing the repairs of critically needed BK-4 units, was tasked to set up repair facilities for number of other electronic systems of Sutluj and Gajraj aircraft.

For his outstanding contribution to service, initiative and displayed of exceptional technical skills, the President is pleased to award Vishisht Seva Medal to Sqn Ldr Rangasamudram Kylasam Sekar.
