Question

Which of the following can be considered as the worst feature of an aircraft in terms of maintainability?

(a) Requirements of removing number of major structural elements

(b) Easily reachable parts

(c) Easily accessible parts

(d) More accessibility is provided for components

I have been asked this question in homework.

This is a very interesting question from Configuration Layout topic in portion Configuration Layout Considerations of Aircraft Design

Answer 1

The correct choice is (a) Requirements of removing number of major structural elements

The explanation is: Easily accessible and reachable parts are primary requirement of maintainability considerations. Accessibility directly affects the effort and maintainability of an aircraft. If a design requires removal of major structural elements to access the component then, it is considered as the worst design based on maintainability.
