Should I present Pratt's evaluation to my FAA office in Orlando to get their opinion? If the FAA blesses Pratt's decision, I feel this could provide the confidence to the buyer, all is above board and overhaul by FJTurbines is good. If the FAA determines it should have been shop Peened, then we have to force FJTurbines to repair. The FAA is the final decision maker in this event. Shop I present to FAA or wait to hear from the buyers ? Pls advise?

Cc: Global Operations Center Subject: RE: [External] Urgent assistance needed PWJT8D-219 Case # CAS-34153-L7J0T7 Larry, NOTE: The following technical opinion is furnished to you based on the information that was provided to Pratt & Whitney. This opinion does not constitute FAA / DER approval. Your request has been reviewed by our JT8D Fleet Manager and offers the following response. The following is the clarification for what the Engine Manual says. 1. Engine Manual P/N: 773128 Section 72-36-45 Insp-00 Page 801/802 states the following. C. Shotpeen the Slots: the 'OR' needs to be used correctly. The note actually says: Shotpeening is necessary if the protective coating has been stripped and the disk has accumulated more than 5,000 cycles or 7,500 hours since new -OR- Shotpeening is necessary if the protective coating has been stripped and the disk has accumulated more than 5,000 cycles or 7,500 hours since shotpeened at the last overhaul of the disk EFTA00818214 -OR- Shotpeening is necessary if the protective coating has been stripped and there is galling of the blade slots. There is NO 'comma' between the two words 'new or, such that they are not individual criteria. They are instead a grouped comparison. This disk is not first run (new) so the first criteria is not applicable. 2. Engine Manual 773128 Section 72-36-45 INSP-01 Page 805 (16) is called out in SB6435 for the disks. However, the location that this is called out in the SB is to establish the number of years for when the disk LAST HAD A SHOTPEEN (not that a shotpeen was NOW needed). 3. Engine Manual 773128 Section 72-36-45 Repair-03 (Ni-Cad replacement) Page 903 Number (9): Same comment on how to read the 'OR' statement as item 1 (above). If the conclusion from the Note in Engine Manual P/N: 773128 Section 72-36-45 Insp-00 Page 801/802 is 'No Shotpeening required at this overhaul', then Engine Manual 773128 Section 72-36-45 INSP-01 Page 805 (16) task is at the repair shop or operators discretion as the prior note provides authorization to not shotpeen in this scenario. As you probably know, shotpeening is used to impart desired compressive stresses into the disk metal surface. In- service normal operation reduces these stresses such that at some interval of use, it is necessary to re-impart these stresses (by shotpeening). When the disk is stored on a shelf (not loaded) there is no loss of compressive stress.

Shotpeen the Slots NOTE: Shotpeening is necessary if the protective coating has been stripped (YES - Disk Overhauled in 2009 with 9,782 Total Cycles & then again in 2014 with same 9,782 Total Cycles) and the disk has accumulated more than 5000 cycles or 7500 hours since new (YES - Disk OverhauledIn 2009 with 9,782 Total Cycles & then again in 2014 with same 9,782 Total Cycles) or shotpeened at the last overhaul of the disk (YES - Disk Overhauled in 2009 & Shotpeened), or if there is galling in the blade slots. 2. AD 2003-16-05 requires the compliance of 586435R1 which in turn references the Engine Manual 773128 Section 72-36-45 INSP-01Page 805 (16). See below. EFTA00818216 (16) Compressor Disk Blade Slots (a) At each overhaul, strip old coating and plate. Shotpeen slots. Replate slots and reapply coating 3.Engine Manual 773128 Section 72-36.45 Repair-03 (Ni-Cad replacement) Page 903 Number (9). See below. (9) If the disk has accumulated more than 5000 cycles or 7500 hours since new or shotpeened at the last overhaul of the disk, shotpeen the slots by SPOP 501. See Standard Practices Manual, PN 585005, Section 70-41-02. See Figure 902. This is clearly an interpretation issue. Please provide Technical Data that require shotpeen 7500 Ws and 5000 cycles since last overhaul as all data states since new. This disk has accumulated 17,794.5 Hrs. and 9,782 cycles since new, has had the coating stripped and was shotpeened at the last overhaul. The presence or lack there of galling is the only criteria that doesn't mandate this shotpeen. Therefore as you can see in the case of this disk (C11 PN:815711.002 SN: BENCAS2345). coating stripped (yes) and 7500 Hours! 5000 Cycles (yes) or Shotpeened at last overhaul (yes) or galling in blade slots (No) mandates the shotpeen during the 2014 strip & recoat of same.

From: Lvjet mailto: Sent: Friday, September 09. 2016 10:46 AM To: Global Operations Center; BRITTON, TIMOTHY W PW Subject: [External] Urgent assistance needed PWJT8D-219 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. 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. " 11FJTurbine 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). Chris, can you give me your opinion on this matter please? thank you, Larry Visoski Director of Operations N908JE Boeing 727-100 Volsan EFTA00818218 EFTA00818219
