## EASA AIRWORTHINESS DIRECTIVE

AD No . : 20 12 - 0215 R1

Date: 04 January 201 3 Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation. This AD is issued in accordance with EC 748/2012, Part 21.A.3B. In accordan ce with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may ope rate an aircraft to which an AD applies, except in accordance with the requirements of that AD, 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) exempt ion].

. These engines are known to be installed on, but not limited to, Boeing 757 series and Tupolev TU 204 series aeroplanes. Reason: During investigation of a star t ing problem with an RB211 - 535E4 - B - 37 engine, the Fuel Spray Nozzles (FSNs) appeared misaligned and the engine was removed. Further investigation found that the FSNs were correctly positioned but that the Front Combustion Liner (FCL) metering panel (referen ce Engine Illustrated Parts Catalogue EIPC section 72 - 41 - 13, Figure/Item 02 - 324) was cracked and distorted. Laboratory investigation revealed that the FCL metering panel was made of N75 material rather th an the specified C263 material.E ASA AD No.: 2012 - 0215R1

Rolls - Royce (RR) iss ued SB RB.211 - 72 - 7221 in 1984, to address the issue of cracking of FCL metering panel manufactured in N75 material. SB RB.211 - 72 - 7221 replaces the FCL metering panel manufactured in N75 material with one manufactured in C263 material. The FCL metering panel in so - called Phase 2 combustors of the RB211 - 524G/H and RB211 - 535C/E4/E4 - B series engines was specified in C263 material from engine type at entry into service. Based on these findings, it w as determined that installation of N75 material FCL metering panels on an engine , where C263 was the intended material , may result in metering panel cracking and distortion. This condition, if not detected and corrected, could result in hot gas break out from the engine casing and potentia lly cause an uncontrolled fire. For the reasons described above, this AD requires inspection of FCL metering panels to determine their material and , depending on findings, replacement of pa nels with panels of correct material specification. Furthermore, this AD prohibits installation of FCL metering panel s on an engine unless the affected FCL metering panel has been inspected and found to be made of the correct material. This AD has been revised to make reference to approved instructions t hat allow , following an on - wing inspection, limited operation of an engine with an affected FCL metering panel in s talled , prior to FCL metering panel in - shop replacement, in accordance with advanced criteria provided in Revision 3 of RR NMSB RB.211 - 72 - AG046 (for RB211 - 535 series engines) or RR NMSB RB.211 - 72 - AG183 (for RB211 - 524 series engines) , respectively

. (2) FCL Metering Panel Replacement: (2.1) If , during an in - shop inspection as required by paragraph (1) of this AD, it is found that the FCL metering panel is made of N75 material , before release to service of the engine, replace the FCL metering panel with one that has been determined to have been made o f C263 material. (2.2) If, during an on - wing inspection as required by paragraph (1) of this AD, it is found that the FCL metering panel is made of N75 material, replace the FCL metering panel with one that has been determined to have been made of C263 material in accordance with the criteria, within the fly - on time period specified in , and in accordance with the instructions of paragraph 3 of RR NMSB RB.211 - 72 - AG046 Revision 3 (for RB211 - 535 series engines) or RR NMSB RB.211 - 72 - AG183 Revision 3 (for RB211 - 524 series engines). (3) From the effective d ate of this AD, do not install on any engine an FCL metering panel unless th e FCL meteri ng panel has been determined to have been made o f C263 material.E ASA AD No.: 2012 - 0215R1
