Yes the Pilot is absolutely correct about the AIRFRAME LIFE AND FLYING HOURS LEFT, PROVIDED YOU HAVE THE SPARE PARTS READILY AVAILABLE, INCLUDING THE TYRES.
LET ME REMIND YOU ALL THAT POST 1975, A SQUADRON OF BRAND NEW MIG-21, MI-8 HELICOPTERS, 5X AN-24/26 TRANSPORT ACs+ all AD RADARS PURCHASED BY BARTER TRADE FROM THE FORMER USSR, ALSO HAD FULL AIRFRAME LIFE, AND FLYING HOURS REMAINiNG, yet they were grounded FOREVER due to the suppliers reluctance to provide Bangladesh with necessary spares,. FINALLY SOME ENDED UP IN MUSEUMS, AS GATE KEEPERS.WHILE OTHERS WERE SCRAPS IN DHOLAIKHAL OF DHAKA.
THIS TIME, I HOPE AND PRAY THAT WE CAN SOMEHOW BE ABLE TO OBTAIN NECESSARY SPARES, AS THE PRESENT RUSSIAN-UKRAINIAN HOSTILITIES MAY TAKE DECADES TO RESOLVE.
MOREOVER ITS UNIVERSALLY KNOWN THAT MAINTENANCE COSTS OF TWIN BURNERS AC ARE VERY HIGH COMPARED TO SINGLE ENGINE MULTIROLE FIGHTER AC i,e F-I6, JF 17,etc,etc.
