SUMMARY: This AD was prompted by reports of thrust reverser unit (TRU) beams found with evidence of thermally caused material degradation in the rearmost section of the TRU beam at certain latches.

This AD requires an inspection for heat damage of each left-hand and right-hand TRU beam as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference.

Depending on findings, this AD might also require inspections of the TRU beam latches, the TRU beam clevises, and the thrust reverser outer fixed structure rear area; corrective actions; and replacement of TRU beams.

DATES: This AD is effective December 18, 2019.
