If an aircraft manufacturer installed 2017 rivets that are to be replaced, can a repair using 2117 rivets be approved?

The question revolves around the strength and suitability of different types of rivets for aircraft repairs. 2117 rivets actually have a lower shear strength compared to 2017 rivets. Therefore, replacing 2017 rivets with 2117 rivets would not be advisable as it would compromise the structural integrity of the aircraft.

In aviation, adhering to manufacturing specifications and maintaining the strength characteristics of the original parts is critical for safety and performance. The use of a rivet that is weaker than the original can lead to potential failures in load-bearing components, which is why strict guidelines govern such replacements.

The correct understanding is that when conducting repairs, any substitute or replacement materials must match or exceed the original specifications in terms of strength and functionality. Using a rivet that does not meet these criteria would be unacceptable under regulations governing aircraft maintenance and repair.
