===Ryanair Flight 6606===

On 9 October 2018, the [[Boeing 737 Next Generation|Boeing 737-800]] operating the flight from Porto Airport to Edinburgh Airport suffered a left ADIRU failure that resulted in the aircraft pitching up and climbing 600 feet. The left ADIRU was put in ATT (attitude-only) mode in accordance with the [[Quick Reference Handbook]], but it continued to display erroneous attitude information to the captain. The remainder of the flight was flown manually with an uneventful landing. The UK's AAIB released the final report on 31 October 2019,<ref>{{Cite web|url=https://www.gov.uk/aaib-reports/aaib-investigation-to-boeing-737-8as-ei-gjt|title=AAIB investigation to Boeing 737-8AS, EI-GJT|last=|first=|date=|website=|url-status=live|archive-url=|archive-date=|access-date=}}</ref> with the following recommendation:<blockquote>It is recommended that Boeing Commercial Aircraft amend the Boeing 737 Quick Reference Handbook to include a non-normal checklist for situations when pitch and roll comparator annunciations appear on the attitude display.</blockquote>
