As earlier mentioned no inspection is required if exceedance is less than 20 kts
Of curiosity, do you need to make a tech log entry? And if so, can you sign it out yourself.
On Boeing it's a mandatory tech log entry, and only a certified maintenance technician can sign it off. Hence, an AOG item when flying to a remote airport with no maintenance.
P.s. On Boeing it's a non-issue to use speed brakes.
