Technician A says that failure analysis will assist the technician in determining whether it is more cost effective to replace rather than repair an engine. Technician B says that when an engine fails under warranty, the manufacturer may want it back for complete analysis of why it failed. Who is correct?

The correct option is;

Technician A

Explanation:

Here we note  failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.

However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.
