Bushings, blades and compressor
In one of the multiple Technical Orders that arrived at the Maintenance Squadron, it was required the substitution of the metal bushings where the blades of the first echelons of the compressor, in all of the engines, rotated, because they could cause the loss of the compressor during flight.
That is why it was not allowed for any engine to fly more than 300 hours without changing those bushings.
There was a surprise (in the well performing Maintenance) when they discovered that after receiving a F-104G with the IRAN performed in FUS (Germany) and with its engine, which had been Overhauled (placed at zero hours), to which the Technical Order had not been applied.
To the small Spanish Maintenance it was incomprehensible that an oversight of such caliber could occur.
