Summary

The purpose of this Service Bulletin is to introduce a High Pressure Turbine (HPT), Advantage

Performance Upgrade (APU) configuration for the PW4000-94(-3) engine models. The new APU

has hardware that is common to the PW4000-100 Advantage70TM series engine models to provide

improved engine performance and durability for extended time on wing and improved Thrust Specific

Fuel Consumption (TSFC). This APU addresses known durability and performance deterioration

problems associated with turbine blades and outer duct segments such as 1st stage duct segment

coating spallation and 2nd stage blade stretch and fracture. The APU also requires the installation

of an Advantage70TM 1st stage hub to maintain the HPT system balance and major rotating part

life requirements.

* This estimate of engine serial numbers will be revised, if necessary, when parts are

installed in engines at Pratt & Whitney.

NOTE: The engine serial number effectivity data and its related engine model

identification contained in this Service Bulletin are taken from the records of

part(s) incorporation during initial manufacture.

After initial engine manufacture, but before final delivery, P&W may change

part(s) in the engine or change the model identification of the engine. Such

action is recorded on FAA337 forms.

To find Service Bulletin PW4ENG 72-795 models that are applicable, the

owner/operator of the engine must compare the Service Bulletin List supplied

with the engine as sent from P&W and the List of Changes incorporated at the

Airframer from FAA337 forms to the Service Bulletin PW4ENG 72-795 Effectivity

section.

This Service Bulletin also applies to engines converted to Phase III (-3) configuration by

Service Bulletin No. PW4ENG 72-490, No. PW4ENG 72-504, or No. PW4ENG 72-572.

This Service Bulletin (SB) also applies to engines identified with a suffix as follows:

(-3A) configuration introduced by SB No. PW4ENG 72-588.

(-3A) configuration introduced by SB No. PW4ENG 73-150.

(-3B) configuration introduced by SB No. PW4ENG 72-512.

Concurrent Requirements

There are no concurrent requirements.

Reason

1. Problem: The PW4000-94(-3) series engine models do not incorporate the latest

HPT technology.

2. Cause: Not applicable.

Not Applicable.

The material data that follows is for each engine.

NOTE: It is possible to use the Chapter/Section and Figure/Item reference number

shown below the old part number to find the part in the Illustrated Parts Catalog.

Because there are many different configurations used, it is frequently necessary

to show more than one group of parts. When this occurs, parts that are

interchangeable are shown line-by-line only, unless this is shown differently.

CAUTION: THE FOLLOWING MATERIAL DATA TABLE(S) ARE ORGANIZED BY

ILLUSTRATED PARTS CATALOG. ALL PARTS IN THE TABLE(S) MAY OR

MAY NOT BE APPLICABLE TO ALL THE ENGINE MODELS SHOWN

IN THE TABLE HEADING. YOU MUST REFER TO THE APPROPRIATE

ILLUSTRATED PARTS CATALOG FOR ENGINE MODEL APPLICABILITY

USING THE OLD PART NUMBER (PN) AND CATALOG SEQUENCE

(6) Assemble the 1st stage HPT duct support assemblies to the case and vane

assembly as specified in Reference 5, 6, or 7, Engine Manual, Chapter/Section

72-52-03, Assembly-01 except do the procedure as follows where applicable.

NOTE: Reference 5, 6, and 7, Engine Manuals Chapter/Section 72-52-03,

Assembly-01, Revision 94, dated January 1, 2011 is scheduled to

incorporate the assembly procedure related to this Service Bulletin and

will take precedence over the Service Bulletin.

(a) Install the 1st Stage HPT Duct Support Assembly, PN 55L028 and 20 1st

Stage HPT Duct Support Assemblies, PN 53L218 (called support segments)

as follows. See Figure 8.

1 Locate the short and long recessed slots in the side of each support

assembly. Install a short Seal, PN 50L239 into the right side of each

support with the shorter side of the seal into the recessed slot. Install

a new long Seal, PN 55L035 into the right side of each support.

Use Paraffin Wax Blend P05-396, as necessary, to keep the seals

in position.

2 Locate the support segments groove in the front Inner Diameter (ID)

flange of the turbine case as shown.

3 Install the support assembly with the Gasket, PN 55L050 (open side

up) into the inner flange of the HPT case, and engage the center pin in

the support with the single slot in the HPT case flange. The two outer

pins will engage the cutouts in the HPT case flange.

4 When you install the remaining support assemblies, carefully put the

gasket into the grooves in each support assembly so that the gasket will

be between the support assemblies and the HPT case. Use Paraffin

Wax Blend P05-396, as necessary, to keep the gasket in position.

NOTE: When you install the last support segment, it can be

necessary to lift the first support and install the last and first

support segments together.

CAUTION: USE CARE NOT TO BEND OR MOVE THE SEALS OUT

OF POSITION.

5 Use an applicable hand held drift (aluminum or other soft material) and

mallet to install the support segments into the case. Install the support

segments equally in small increments (do not bend or move the gasket

or seals out of position).

6 With the support segments installed, make sure that the seals are

installed correctly.

7 On the support ring (PWA 87003), tighten the 21 adjustable torque

thumbscrews until the screws will not turn.

(b) Install three 1st Stage HPT Band Segment Assemblies, PN 55L032-01 as

follows. See Figure 6.

1 Install three 1st stage HPT band segments into the inner groove in the

1st stage HPT duct supports. Engage the seven cutouts in each band

segment into the pins of the supports.

2 Make sure that the tabs on the ends of all band segments are on the

outside of the adjacent segments.

3 Install a spring gasket on the ID face of the 1st stage HPT duct

supports.

4 Install a spring gasket into the groove at the rear of the duct segments.

(c) Install the 42 1st Stage HPT Duct Segments, PN 53L236 as follows:

CAUTION: BE CAREFUL WHEN YOU TOUCH THE DUCT SEGMENTS

TO PREVENT THE CERAMIC COATING FROM FLAKING

OR CHIPPING.

1 Align the slot in the foot of the duct with the dowel pin in the rear groove

of the duct support. Install the duct segments (chamfered end down)

into the outer groove in the duct support. Apply pressure with your

hand only and partially install the duct segment.

2 Assemble the 42 1st Stage HPT Duct Seals, PN 50L285 into the seal

grooves between adjacent duct segments. Use Beeswax P05-395

or Paraffin Wax Blend P05-396, as necessary, to keep the seals

in position. Engage and install the remaining duct segments in a

counterclockwise direction into the duct supports.

NOTE: Counterclockwise installation of the duct segments helps

align locating pin slots in the ducts with locating pins in the

supports.

(7) Replace 21 2nd Stage HPT Duct Segments, PN 50L629 with PN 53L135 or do a

modification of the 21 2nd Stage HPT Duct Segments, PN 50L629 as follows.

See Figure 7.

NOTE: For PW4158(-3) engine model, 2nd Stage HPT Duct Segment,

PN 53L135 was introduced in Reference 24, Service Bulletin No.

PW4ENG 72-735.

(a) Send the parts to a vendor listed in the Vendor Services section. The

modified 2nd stage HPT duct segments will be returned identified as

PN 53L135.

(8) Reidentify the case and vane assembly as given in Table 2 below when all the

1st stage and 2nd stage HPT blade outer air seal parts are installed. See the

Interchangeability section for Table A and Table B. Mark the new part number as

specified in Reference 1, Standard Practices Manual, Chapter/Section 70-11-00,

Class 40. See Figure 4 for the location of marking.

Number values shown in parentheses adjacent to U.S. values are International System of

units (SI) equivalents.

To calculate part life, include the hours and/or cycles since the part was made. Use the total

hours or cycles to calculate life limits that are the result of part modification, a part used in an

engine with different thrust, or for some other reason.

Revision to Table of Limits

Engine Manual(s), Chapter/Section 05-10-00, Revision 94, dated January 1, 2011 is scheduled

to incorporate the Part Service Life Limits related to this Service Bulletin and will take

precedence over the Service Bulletin.
