Working on RB211-535C powered B752SFs & since soon the RB211-535E4 powered B752SFs would be arriving at the Airline.The RB211-535Cs being the older B752s there were a lot on upgrades along the way.
Anyone aware of the upgrades Airframe wise.I've heard about the Ice detector,the Stab trim switches & Alt L/G ext switch type have been varied.

Some of ours have a new type RH recirc fan installed, the original type didn't last well. So there's a mod to install a 767 recirc fan in it's place.
Our Freighters dont have the RH recirculation fan Installed so I guess that mod would be not applicable to Freighters.However what was the advantage of the B767 fan.
several years ago the cockpit Korry switches were replaced to remove the #387 bulbs - the replacements have LED's.
Guess this was due burn out.
There are dozens of mods, but at 3 AM while waiting for flights to straggle in for the night my brain can't think of many more.
No probs.Rest well & get back.Much appreciated.

Hi MEL, Buzz here... busy night, lots of late airplanes.
The advantage to the 767 RH recirc fan is that it doesn't seem to fail... the 757 RH recirc fan tends to die after a few years.
And the 767 fan has a higher airflow, nice to have in the summer.
