TAESLs Technical Instruction System

• This presentation has been prepared especially
  for TAESLs approved suppliers as a training aid
  to provide explanation of the TAESL Technical
  Instruction System. This is an effort to
  eliminate costly delays due to the
  return-to-service documents not being completed
  properly.
• Your help in this matter is greatly appreciated.

Background INFO.

• ESO for American Airlines (AA)
• The ESO (Engineering Specification Order) is an
  American Airlines Document. It consists of the
  Rolls-Royce engine manual (white pages) amended
  by American Airlines with ESO (Pink Pages)
• NOTE This does not mean that the white pages of
  the AA/ESO is equivalent to the Rolls-Royce OEM
  manual.
• In an effort to standardize the work performed at
  TAESL, American Airlines has given approval that
  work performed on American Airlines Rolls-Royce
  engines can be performed in accordance with the
  Rolls-Royce Engine Manual series and TAESL
  Technical Instructions. In other words the
  Rolls-Royce Manuals TAESL Technical
  Instructions the American Airlines ESO (90042
  for the RB211 and 20777 for the Trent 800)
• This approval, from American Airlines, provides
  TAESL and our suppliers the ability to work to a
  one-manual system (i.e. Rolls-Royce OEM manuals).

CU-TIs(Customer Technical Instruction)

• CU-TIs
• Are specific instructions from the customer
  pertaining to the repair of engine parts and
  components for TAESL.

4
TIs(Technical Instructions)

• TIs
• Provide technical deviations from existing manual
  repairs.
• Provide clarification of existing manual repairs.
  
• Only apply to the repair(s) if the TAESL customer
  has approved the TI
• NOTE Many of the TAESL Technical Instructions
  (TIs) are verbatim of the American Airline ESO
  (pink pages)

5
Destroying the MYTH about TIs

• Just because a TI exists, and is approved by the
  customer, does not mean the TI is required on
  every part being repaired.

6
Engine Parts Received at the Supplier

• When the parts are received at the supplier with
  the TAESL Repair Order, the supplier must review
  the TAESL Repair Order for
• The Repair Instructions
• Customer/ Owner (e.g.
  American Airlines, America West, Delta, etc)

Engine PartsReceived at the Supplier

• The supplier must review the CD ROM provided by
  TAESL, for the applicable customer CU-TI for
• Any special instructions that may pertain to the
  supplier in order to comply with our customer or
  TAESL requirements.
• The supplier must also review TAESL.com for
• the Approved Technical Instructions that may be
  employed during the repairs (if applicable).

8
Note

• The supplier should have a process in place that
  provides their appropriate shop or department
  with the information on the TAESL CD ROM disk.

Return to Service Tag

• When preparing the Return-to-Service tag (FAA
  Form 8130-3, JAA Form One or TC 24-0078) the

  referenced in either Block 5 or 13.)

Return to Service Tag(continued)

• Block 13 must note the Rolls-Royce engine manual
  ATA section/chapter used to repair the part, and
  in parentheses reference the appropriate CU TI.

Rolls-Royce Engine manual 72-XX-XX (ESO 90042,
CU0002)
EXAMPLE Repaired in accordance with

• Technical Instructions (TIs) that were employed,
  or accomplishment of special repairs should be
  noted in block 13 as well.
• NOTE This may include the suppliers own
  approved repair(s), if authorized for use, such
  as DER, etc.

EXAMPLE TIs RB00XX and RB0XXX and/or HRS XXXX
and/or NCR 200XXX accomplished.
12
Parts Returned to TAESL

• If the parts and the paperwork (Return-to-Service
  documents) are correct, TAESL can provide the
  parts to our shops without holding the parts and
  requesting our supplier to make corrected
  documents.
• Requesting corrections takes time and possibly
  delays the turn time to our valued customer.
