Final answer:
The correct action when an Integrated Drive Generator scavenge oil filter is contaminated with metal is to remove, inspect, and possibly repair or replace the IDG, while documenting the process.
Step-by-step explanation:
The correct answer is option A: If the Integrated Drive Generator (IDG) scavenge oil filter is contaminated with metal, it indicates that there could be abnormal wear or damage to the IDG's internal components. Aviation maintenance standards assert that one should not ignore such a finding. The contaminates could potentially cause an in-flight failure. Therefore, the appropriate procedure is to remove and inspect the IDG, and the scavenge oil filter itself. The inspection may reveal the source of the contamination, and determine whether the IDG can be cleaned, repaired, or if it needs to be replaced. Depending upon the severity of the situation, the aircraft may be grounded until the maintenance issue is resolved to ensure safety of operation. It is also important to document the finding and the corrective action taken in accordance with regulations and the aircraft's maintenance manual.
If the Integrated Drive Generator (IDG) scavenge oil filter is contaminated with metal, it can indicate a serious problem with the IDG and its bearings. Metal contamination in the oil filter can be a sign of wear or damage in the IDG, which can lead to further issues if not addressed.
Replacing the scavenge oil filter is the appropriate course of action in such a situation to prevent any potential damage to the IDG and ensure its proper functioning. It is important to regularly inspect and maintain the IDG and its components to avoid further problems.
