Apache: Replacing the Midframe Oil Drain Tube Coupling Nut

Photo by Charles Rosemond
Mechanics, you spoke and the Apache T700 Office listened. You suggested that the field could repair the B Nut (PN R197P04) on the engine cold section module (CSM), instead of purchasing a new CSM, and save money. Just request these maintenance engineering orders (MEOs) from your logistics assistance representative (LAR) to get the job done.

The numbers of the MEOS are as follows:
  • P7394 - WP "DIFFUSER AND MIDFRAME CASING ASSEMBLY"(file m00066) Midframe Oil Drain
  • Tube Coupling Nut Replacement, PNs R197P04, P7395 - RPTSL, DIFFUSER AND MIDFRAME CASING ASSEMBLY" (file r00010) PNs R197P04 and R261P04, SMR Code Update
Over time, these MEOs will be combined into a work package and incorporated into a future update to TM 1-2840-248-23&P (Oct 19).
