"B".

Between A and B, I choose "B". not only...but also idiom needed and B is more concise than A.

(B)
not only ... but also is right
omitting "should" after demand is right

Can one of you explain why A) is wrong?

Aviation officials have not only failed to determine the cause of the crash, but they have also ignored demands by the pilots union that the investigation should be expedited.

I had picked A, for it seemed to be more parallel. Is the use of not only but __ also in A wrong?

nocilis! Yes the Usage of "not only.. but also" in (A) is wrong...

look choice (B) more closely.. It maintains correct parallelism..
Aviation authority have not only failed.... but also ignored....

One more interesting thing to note in this sentence is that second clause (but also..) is in "SUBJUNCTIVE MOOD."

B is most concise and parallel:
Aviation officials have
not only
1- failed to determine the cause of the crash
but also
2- ignored demands by the pilots union that the investigation be expedited

As you can see, "have" applies to both participial phrases and does not need to be repeated as in (A).

I guess no one has noticed the use of [size=18]Subjunctive[/size] here. Well B is best and I would say the only and only reason is subjunctive---which makes the Option B more concise and clearer than A.

Opps I just noticed that ppl have made some reasoning about Subjunctive. Well that I am in for subjunctive.

another way of seeing it: "not only... but also" is the correct idiom here. (B) is my choice.

I don't think it has anything to do with subjunctive mood. Paul's explanation is correct.

It's not correct to say: He has not only done this, but also he had done that.
Correct way is: He has not only done this, but also done that.
Or: Not only has he done this, but also he has done that.

I concur. In this forum, we use subjunctive mood as an explanation even though it is entirely inappropriate.

Although it might not really apply....I had rejected A and B initially because of "pilots union"

I thought it should be "pilots' union"

Any thoughts on that?

B. Not only X but also Y needs to be ||. since after not only is the past tense verb failed another past tense verb after the also must follow and nothing inbetween. so B is the only choice.

B also uses the subjunctive properly that... be. and is not confusing.

About the pilots versus pilots' issue.

"Pilots" seems to be correct. I'm not sure why in terms of grammar, but if you look around, you will notice that it is true by convention.

For example, their official website is titled, Freelancers Union. Also, Teamsters Union comes to mind. Maybe it means, union of freelancers, instead of union (owned by) freelancers, or freelancers'.

reading word 'demand's tell me go subjunctive. 'Not only' goes well with 'but also'
