Assertion (A): An engine pylon is designed with a deliberate weak link.

Reason (R): In a severe overload the engine should separate cleanly rather than tear the wing open.

Select the correct answer from the options below.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Both statements are true and the second is the reason for the first. Losing an engine is survivable; losing the wing structure and its fuel tanks is not. The fuse pin arrangement is a certification consideration and has been the subject of accident investigation more than once.
