Vintage IAF aircraft quality audit in 2013 blamed UPA

“The springs installed in fuel pump aggregates of R-25 aero-engines are failing frequently. MiG 21 Bison aircraft accident, which occurred in November 2012 has been attributed to the failure of springs due to surface corrosion. Out of the five Main Fuel Pumps fitted with Hindustan Aeronautics Limited manufactured springs, spring failures were found on three Main Fuel Pumps, which is a cause for serious concern.

This 2013 confidential quality audit report of the IAF clearly indicts the decision makers in the UPA and previous governments including NDA 1 headed by Atal Bihari Vajpayee. It further shows how the air warrior’s capabilities were grossly undermined. Why UPA in its 10 years of the rule did nothing for ‘outdated jets’?

The report further said: “There have been high failures of Main Fuel Pumps since the 1990s, due to a fuel leak from pump drive end. Throttle lever and centrifugal governor end of Main Fuel Pump of R-25/R-25 U aero-engines. The MiG 21 has often been termed as “flying coffin” and the confidential report clearly answers the ‘why’ lingering on the mind. The successive regime has been careful in their statement regarding MiG accidents to justify the status quo.
