Anti-hijack doors installed after the 9/11 attacks have suffered repeated glitches over the years.

(Newser) – Doors designed to keep intruders out of aircraft cockpits may be faulty on at least 1,600 commercial jets, according to aviation industry insiders. Authorities in the US and elsewhere have ordered repairs be made to hundreds of Boeing 747s and Airbus A320s in the coming months, sources tell the Wall Street Journal.

The problems include glitches with the electronic controls used to secure the doors which can leave them jammed open. The repairs—outlined in a directive published by European regulators and worrying FAA officials concerned about the sensitivity of the information—follow three previous rounds of widespread changes to anti-hijack doors.
