Engine mount members should preferably be repaired by using a

smaller diameter tube with straight welds.
larger diameter tube with fishmouth and rosette welds.
similar diameter tube with overlapping welds.
composite material patch and adhesive.

The correct answer is: larger diameter tube with fishmouth and rosette welds.

Engine mount members are critical components that must meet specific strength and reliability requirements to ensure the safety of the aircraft. Using a larger diameter tube with fishmouth and rosette welds is the preferred method for repairing engine mount members. A larger diameter tube provides increased strength and structural integrity to support the engine loads. Fishmouth and rosette welds create a strong and smooth joint that distributes the load more evenly, reducing stress concentrations that can lead to premature failure. This type of weld also helps maintain the original contour and strength of the mount member. Options A and C are incorrect as using a smaller diameter tube or overlapping welds may compromise the strength of the repair, leading to potential failure under load. Option D is also incorrect as using a composite material patch and adhesive may not provide the necessary strength and durability required for engine mount members.
