TAESL’s Technical Instruction System

This presentation has been prepared especially for TAESL’s 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-TI’s(Customer Technical Instruction)

CU-TI’s

– Are specific instructions from the customer pertaining to the repair of engine parts and components for TAESL.

TI’s(Technical Instructions)

• TI’s

– 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 (TI’s) are verbatim of the American Airline ESO (pink pages)

Destroying the MYTH about TI’s

Just because a TI exists, and is approved by the customer,

does not mean the TI is required on every part being

repaired.

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)

• 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).

Engine PartsReceived at the Supplier

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 supplier must provide the following:

– TAESL’s Purchase Order (PO) number (must be referenced in either Block 5 or 13.)

FAA Form 8130-3, JAA Form One, TC Form 24-0078

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.

• NOTE: It is no longer an American Airlines requirement to refer to the ESO, except on LRU’s.

EXAMPLE:

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

EXAMPLE:

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

Return to Service Tag(continued)

• The Return-to-Service tag must provide:

– Technical Instructions (TI’s) that were employed, or accomplishment of special repairs should be noted in block 13 as well.

• NOTE: This may include the supplier’s own approved repair(s), if authorized for use, such as DER, etc.

EXAMPLE:

TI’s RB00XX and RB0XXX and/or HRS XXXX and/or NCR 200XXX accomplished.

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.
