Aborting a Take-Off: An FAA Occurrence

 A lot of pilots don't realize this, but aborting a take-off once the aircraft has crossed the hold short line onto the runway, is an “occurrence” that the local FSDO is supposed to investigate!

http://www.faa.gov/documentLibrary/media/Order/FAA_Order_8020.11D.pdf - Ch. 6, ¶ 6 (emphasis added):

Air Traffic Reports to Flight Standards. ... ATO employees are mandated to report all observed or suspected occurrences which meet the MOR criteria (Reference FAA Order JO 7210.632, ”Air Traffic Organization Occurrence Reporting”). The preliminary reports are received by Flight Standards through the ATQA program or the CEDAR program. It is Flight Standards’ responsibility to analyze and validate the reports through an analysis of the air traffic data. When validated, the investigator should take appropriate actions to mitigate any future reoccurrence of the event by the respective operator, pilot or crew.

https://www.faa.gov/documentLibrary/media/Order/JO_7210.632A.pdf - Appendix A (“Mandatory Occurrence Report Criteria”), ¶ 7(e) (emphasis added):

Any instance in which any part of the aircraft has crossed over the runway hold-short line and the controller cancels the takeoff or the flight crew aborts the takeoff.

(Note that applies to simply “aircraft,” while other paragraphs are specific to, e.g., “turbojet aircraft” (¶ 7(d)).)

That said, if you need to abort, obviously, abort! Just, there may be some paperwork, and a question or two...
