## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2009-0243R2

Date: 18 February 2011

Note: This Airworthiness Directive (AD) is issued b y EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the Europe an Community, its Member States and of the European third countries that participat e in the activities of EASA under Article 66 of that Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be en sured by accomplishing any applicable ADs. Conseque ntly, no person may operate an aircraft to which an Airworthiness Direc tive applies, except in accordance with the require ments of that Airworthiness Directive unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemp tion].

### ATA 72 Engine – Front Combustion Liner Inner Wall – Inspection

Manufacturer(s): Rolls-Royce plc

Applicability: 1. RB211-524 Series Engines, models RB211-524G2-T-19, RB211- 524G3-T-19, RB211-524H2-T-19, all serial numbers, i f Rolls-Royce RB211 Service Bulletin No. 72-D133 or Rolls-Royce R B211 Service Bulletin No. 72-E902 is incorporated. These engines are known to be installed on, but not limited to Boeing 747- 400 series aircraft. 2. RB211-524 Series Engines, models RB211-524H-T-36 , all serial numbers, if Rolls-Royce RB211 Service Bulletin No. 72-D133 or RollsRoyce RB211 Service Bulletin No. 72-E902 is incorpo rated. These engines are known to be installed on, but not limited to Boeing 767 series aircraft. 3. RB211-Trent 700 Series Engines, all models, all serial numbers, if Rolls-Royce RB211 Service Bulletin No. 72-D133 or R olls-Royce RB211 Service Bulletin No. 72-E902 is incorporated.
These engines are known to be installed on, but not limited to Airbus A330 series aircraft. 4. RB211-Trent 800 Series Engines, all models, all serial numbers, if Rolls-Royce RB211 Service Bulletin No. 72-D133 or R olls-Royce RB211EASA AD No : 2009-0243R2

EASA Form 110 Page 2/4 Service Bulletin No. 72-E902 is incorporated.
These engines are known to be installed on, but not limited to Boeing 777 series aircraft.

Reason: Cracking has been found on the inner wall b etween intermediate dilution chutes on a total of five front combustion liners o f the standard corresponding to Rolls-Royce RB211 Service Bulletin No. 72-D133. The lives of two of these liners were confirmed to be b elow the currently valid borescope inspection interval. Ultimately, crack propagation could result in hot g as breakout with potential of downstream component distress and mult iple turbine blade release beyond containment capabilities of the engi ne casings. Thus, cracking of this nature constitutes a potentially u nsafe condition. Since Rolls-Royce Service Bulletin No. 72-E902 intr oduces further developments of Rolls-Royce RB211 Service Bulletin No. 72-D133, engines incorporating Rolls-Royce RB211 Service Bul letin No. 72-E902 are also considered to be potentially affected and are therefore included in the applicability of this AD.
This AD requires a change to the initial and repeat borescope inspection intervals for the front combustion liner.

Revision 1 of this AD was issued in order to clarif y the required actions for combustion liners that have been inspected before t he effective date of the original issue of this AD and in accordance wit h earlier revisions of Rolls-Royce RB211 Series Propulsion System Series N on-Modification Service Bulletin No. RB211-72-AF458.

Revision 2 of this AD is issued to remove from the Applicability paragraph of this AD all models of the RB 211-535 series engi nes. Following the results of the inspections required by this AD, it has been determined by engineering assessment, that those engines are not affected by the unsafe condition related to this AD.

Effective Date: Revision 2: 04 March 2011

Revision 1: 10 December 2009 Original issue: 24 November 2009

Required Action(s) and Compliance Time(s): A. Definition In the following LIFE will be referred as the lowes t of the following lives:
- life of the combustion liner since new, - life of the combustion liner since inner wall rep lacement

- life of the combustion liner since the combustion liner was last inspected in accordance with section 3. Accomplishm ent instructions, subsection A. Borescope Inspection of Rolls-Royce R B211 Series Propulsion System Series Non-Modification Service B ulletin No. RB211-72-AF458 Revision 2 or later approved revisio n.

B. Action Required
It is required to carry out the borescope inspectio ns as specified in section 3. Accomplishment instructions, subsection A. Borescope Inspection of Rolls-Royce RB211 Series Propulsion S ystem Series NonModification Service Bulletin No. RB211-72-AF458 Re vision 4 or later approved revision before the limits specified in pa ragraph C. below. C. Inspection Requirements
i) Initial Inspection RequirementsEASA AD No : 2009-0243R2

EASA Form 110 Page 3/4 1. If the engine has a combustion liner installed w ith a LIFE (see A. above) that is equal to or greater than the initial inspection threshold specified in Table 1 column (b) included in C.iii) below at the effective date of the original issue of this AD.

or the engine has a combustion liner installed with a LIFE (see A. above) that is not known Carry out the action specified in B. above within 2 50 cycles after the effective date of the original issue of this AD. 2. If the engine has a combustion liner installed w ith a LIFE (see A. above) that is less than the initial inspection thr eshold specified in Table 1 column (b) included in C.iii) below at the effective date of the original issue of this AD

, carry out the action specified in B. above before the LIFE (see A. above) has reached the limit specified in Table 1 column (c) included in C.iii) below. ii) Repeat Inspection Requirements Following accomplishment of the Initial Inspection Requirement identified above, carry out the action specified in B. above at repeat intervals not exceeding those specified in Table 1 column (d) included in C.iii) below.
