Compliance
If, before the effective date of this AD, you performed the inspections and corrective actions required by paragraph (e) of this AD using RR NMSB No. RB.211-73-G848, Revision 3, dated June 12, 2014; or RR Alert NMSB No. RB.211-73-AH837, dated September 9, 2014; or paragraph 3.A. or 3.B. of RR Alert NMSB No. RB.211-73-AH522, Revision 2, dated July 18, 2014; or earlier versions, you met the inspection requirements in paragraph (e) of this AD.
Required actions
For the purposes of this AD: (1) An “engine shop visit” is the induction of an engine into the shop for maintenance involving the separation of pairs of major mating engine flanges, except that the separation of engine flanges solely for the purposes of transportation without subsequent engine maintenance is not an engine shop visit. (2) The fan case LP fuel tubes and clips, and the FOHE mounts and hardware, are eligible for installation if they have passed the inspection requirements of paragraphs (e)(1), (e)(2), and (e)(3) of this AD.
Unsafe condition
Comply with this AD within the compliance times specified, unless already done. (1) Within 800 flight hours (FH) after the effective date of this AD, and thereafter at intervals not to exceed 800 FH, inspect the clip at the uppermost fan case LP fuel tube clip position, CP4881, and support bracket, P/N FW26692. Use Accomplishment Instructions, paragraph 3.A, of RR Alert Non-Modification Service Bulletin (NMSB) No. RB.211-73-AH837, dated September 9, 2014, or paragraph 3.A. or 3.B. of RR Alert NMSB No. RB.211-73-AH522, Revision 2, dated July 18, 2014, to do the inspection. (i) If the clip at the uppermost clip position, CP4881, fails inspection, replace the clip with a part eligible for installation and, before further flight, inspect the fan case LP fuel tube, P/N FW53576, for fretting, and clips for cracks or failure, according to Accomplishment Instructions, paragraph 3.A. of RR Alert NMSB No. RB.211-73-AH837, dated September 9, 2014, or paragraph 3.A. or 3.B. of RR Alert NMSB No. RB.211-73-AH522, Revision 2, dated July 18, 2014. (ii) If the support bracket, P/N FW26692, fails inspection, replace the bracket before further flight with a part eligible for installation and inspect the fan case LP fuel tube, P/N FW53576, and clips for cracks or failure. (2) Within 4,000 FH since new or 800 FH, whichever occurs later, after the effective date of this AD, and thereafter at intervals not to exceed 4,000 FH, inspect the fan case LP fuel tube, P/N FW53576, and clips, and the fuel oil heat exchanger (FOHE) mounts and hardware, for damage, wear, or fretting. Use paragraph 3.A. or 3.B., Accomplishment Instructions, of RR Alert NMSB No. RB.211-73-AH522, Revision 2, dated July 18, 2014, to do the inspection. (i) If the fan case LP fuel tube, P/N FW53576, fails inspection, before further flight, replace the fuel tube and clips with parts eligible for installation. (ii) If any FOHE mount or hardware shows signs of damage, wear, or fretting, replace the damaged part before further flight with a part eligible for installation. (3) At each shop visit after the effective date of this AD, inspect the fan case LP fuel tubes, P/Ns FW26589, FW36335, FW26587, FW53577, and FW53576, and clips, and the FOHE mounts and hardware, for damage, wear, or fretting. Use paragraphs 3.B.(1) and 3.B.(2) of RR Alert NMSB No. RB.211-73-AH522, Revision 2, dated July 18, 2014, to do the inspection. (i) If any fan case LP fuel tube fails inspection, replace the fuel tube and clips before further flight with parts eligible for installation. (ii) If any FOHE mount or hardware shows signs of damage, wear, or fretting, replace the damaged part before further flight with a part eligible for installation. (4) If you replace any fan case LP fuel tube, clip, or FOHE mount or hardware as a result of the inspections in paragraphs (e)(1), (e)(2), or (e)(3) of this AD, you must still continue to perform the repetitive inspections in paragraphs (e)(1), (e)(2), and (e)(3) of this AD.
