Hi

Below is a HTP stage 1 cooling duct assembly:

http://209.85.62.24/46/112/0/p173686/_chromalloy01_edit.jpg

It is used on a JTD9 - 7A, or a JTD9- 7F or a JTD9-7J engine(which are used on Boeing 747's)

Is it possible to install this same cooling duct assembly on a JTD9- 7R4D engine(which is used on a boeing 767).....or would it be incompatible?

Thanks in advance.

The reason i ask is because this engine that is puported to have come from United Airlines Flight 175 on 9/11/01....

Has a cooling duct assembly that belongs to either a JT9D 7A or a JT9D 7F or a JT9D -7J

But United Airlines Flight 175 AKA N162UA.....which was a 767-200 had a JT9D - 7R4D engine:

In fact all United Airline 767's were equiped with JT9D 7R4Ds.

Airline: Model Engine
UNITED AIRLINES 767-200 JT9D-7R4D
UNITED AIRLINES 767-200EM JT9D-7R4D

....and a cooling duct assembly on a JT9D-7R4D looks like this:

But is it possible that a JT9D-7R4D could be backward compatible to accomodate a cooling duct assembly from a JT9D- 7A/7F/7J ?
