The US-based company responsible for repairing these vital pieces of aviation equipment has allegedly been goofing on the repair job of its components and the Airport Authority of India (AAI) is on the brink of running out of spares.
A possible breakdown of these parts has the potential to cause a radar blackout, slowing down air traffic movement.
A letter written by AAI's Delhi-based joint general manager (Com) Shakti Dev to his executive director (operations and maintenance) gives an indication of the current state of chaotic affairs.
The missive that was dispatched on January 5 raised an alarm over poor maintenance of the Sband radar.
This device sends signals to approaching aircraft when they are as far as 120 nautical miles from the airport.
The S-band radar parts installed at the Delhi airport were sent to the workshop of radar development major Raytheon of the US.
Appallingly, the devices failed to function upon being installed after repair because the fault had not been rectified, Dev stated.
He also alleged that 'every time Raytheon has assigned a new SAR (site anomaly report) number to the same old part which failed to work after repair and had to be returned to the workshop'.
