During landing, you have experienced severe turbulence that you believe is over the aircraft's structural limitation. There is a charter flight schedules for tomorrow. Do you
a) make a RRM
b) write it on the maint release
c) write it on the maint release and deem it unairworthy
d) inform the chief and deem the aircraft unairworthy.

How to choose between B and C? Can we deem the aircraft is unairworthy?

It's not accurately possible to identify the correct answer because the question presented is likely paraphrased and subtle wording may be lost.

However, we can address it generally.

Make a RRM
RRM need to be made within 72 hours. AIP ENR 1.14 gives examples that could trigger a RRM

an occurrence that results in difficulty controlling the aircraft, including any of the following:
- an aircraft system failure
- a weather phenomenon
- operation outside the aircraft’s approved flight envelope


In my view, this incident could lead to a RRM - particularly, if its established that operations did occur outside the envelope, however it is not the most immediate action you would do and is likely not the best answer

Entry in the maintenance release
Since there's a suspicion of exceeding structural limits an entry should be made!
I found this article which breaks down Maintenance Releases well and saves me adding my 2 cents! :-)

Hope this helps.

Howdy!
Looking at the CAR 47 Maintenance Release 1(a)(iii) and also paragraph (b), it states that if the pilot (or other person listed in the CAR), suspects that abnormal flight or ground loads have been imposed on the aircraft, and there is a likelihood that the aircraft will be flown before the issue has been fixed, the pilot may sign the maintenance release stating the aircraft is un-airworthy.

I would say the correct answer is C, as like SJM says, you would prob need to so report (RRM), however the aircraft is due to fly the next day therefore it satisfies CAR 47 (b) that the aircraft could fly before it is fixed. RRM is 72 hrs, so too long.

Thanks for sharing the question, was good to go and try and find the answer!
