The Global Operations Center (GOC) has reviewed the scenario described below and would concur with the interpretation of the JT8D Engine Manual that if the disk has not accumulated more than 5000 cycles or 7500 hours since new or overhaul (which this one has not) it would not require shot peened again until it reaches that threshold.

From: Lvjet Sent: Friday, September 09. 2016 10:46 AM To: Global Operations Center; BRITTON, TIMOTHY W PW Subject: [External) Urgent assistance needed PWJT8D-219 mailto: Hello Chris Albert and Timothy Britton, PW help line,. couple of months ago, you assisted us with our JT8-219 engines with the assistance of Mark Williams our Rep. regarding a chip in an HPC blade. I have another question regarding C-11 HPC Disc overhaul procedures if you could please assist? A question has come up in regards to proper procedure for Disc overhaul, mainly Shop Peen requirement. EFTA00818324

In 2009 the C-11 HPC Disc part #773128 was overhauled properly and placed in storage preserve according to PW procedures including Shop Peen then Nicad application. I understand storage is good for 3 years. FJTUrbines in Miami, purchased this Disc for our install on PWJT8D-219 engine, This C-11 Disc was never installed on an engine after its overhaul in 2009,. In 2014 FJTurbines overhauled the Disc again, so it could be installed on our engine. According to your procedure, you must shop peen and Nicad each overhaul if 7500 hours or shop Peen was accomplished prior. *** FJTurbine informs that Shop Peen of this C-11 Disc was NOT required, since it was never installed on an engine after its 2009 overhaul, and proceeded to NiCad the Disc, and utilized the 2009 Shop peen cert as being complied with, since no hours or cycles happen since its 2009 overhaul. is it acceptable With Pratt & Whitney to overhaul this disc in this manner? I would like your approval that this was ok? I attached the Disc paper work and Reference the overhaul procedure from PW Sub task 72-36-45-38-019-001 (9).
