If an integrated drive generator oil filter shows metal contamination, how should you fix it?

• A. Clean and reuse
• B. Repair by patching
• C. Remove and replace
• D. Ignore it

Answer: (C)

Metal contamination in the IDG oil filter means debris from wear inside the drive or engine parts has been captured by the filter. The filter’s job is to trap those particles and keep them out of the bearings and gears; reusing a dirty filter would let metal continue circulating, risking further damage to the IDG. Cleaning and reusing or patching a filter doesn’t remove or fix the underlying wear, and ignoring it could lead to a serious failure. The proper action is to remove the contaminated filter and install a new one, and follow the maintenance manual procedures for oil replacement and system inspection to identify and address the source of the metal.
