Compliance

Required actions
Within 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the applicable tasks identified in figure 1 to paragraph (g) of this AD. The initial compliance time for doing the tasks is at the time specified in the applicable tasks identified in figure 1 to paragraph (g) of this AD, or within 90 days after the effective date of this AD, whichever occurs later. Figure 1 to Paragraph (g)—Temporary Revisions and Tasks ER12DE25.000 Note 1 to figure 1 to paragraph (g): The asterisk (or “one star”) with the last three digits of the task numbers listed in table 1 to paragraph (g) of this AD indicates that the task is an airworthiness limitation task.
Unsafe condition
This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address an accumulation of fuel in the auxiliary power unit (APU) muffler caused by a drainage block in the muffler. This condition if not corrected, could lead to an accumulation of fuel in the muffler being ignited by the high-temperature exhaust gases in the muffler, and could subsequently lead to an uncontrolled fire in the APU bay.
Affected ADs
None.
