Unsafe Condition
Installation of N75 material FCL metering panels on an engine where C263 was the intended material may result in metering panel cracking and distortion.
Required Actions
Inspect the front combustion liner (FCL) metering panel to determine if it is made from N75 material and, if so, replace it with an FCL made from C263 material. You may use RR Alert NMSB No. RB.211-72-AF572, Revision 2, dated April 2, 2009, or Revision 1, dated October 10, 2008, or paragraph 3.B. of the Accomplishment Instructions in RR Alert NMSB No. RB.211-72-AG183, Revision 3, dated December 6, 2012, for engine shop visit inspections. You may use paragraph 3.B.(5)(p)(i) of RR Alert NMSB No. RB.211-72-AG183, Revision 3, dated December 6, 2012, and a spectroscopic analysis, instead of paragraphs 3.B.(3) through 3.B.(5)(p) and paragraphs 3.C.(5)(q) and (r). You may use a local facility in the context of an FAA-accepted maintenance or quality plan to perform the spectroscopic analysis. The accomplishment instructions in paragraphs 3.B.(6)(g)(iii) and 3.B.(6)(j)(i) of RR Alert NMSB No. RB.211-72-AG046, Revision 3, dated December 6, 2012, specify use of RR tooling for the post-inspection fuel manifold pressure test. However, you may use locally sourced tooling in the context of an FAA-accepted maintenance or quality plan.
