Question to the Department for Transport:

To ask the Secretary of State for Transport, how many emergency landings there have been at Heathrow Airport in the last five years.

The Department does not collect data on how many emergency landings there have been at Heathrow Airport. However if serious enough, such incidents would be counted amongst data for safety related events. These are defined as an event which endanger or which, if not corrected or addressed, could endanger an aircraft, its occupants or any other person. They have to be reported to the Civil Aviation Authority as part of the Mandatory Occurrence Reporting Scheme (MORS).

Occurrence reporting is now covered by (EU) Regulation No 376/2014. The Regulation requires that the reporting, analysis and follow-up to such occurrences remain confidential. However, the Regulation does permit information to be released on request to interested parties that have a genuine safety related need for the information.
