In 2011, the flight from New Jersey, U.S. to Warsaw, Poland was forced to make an emergency gear up landing (commonly referred to as a “belly landing”) at Warsaw Airport. The incident was due to multiple failures of the landing system including, a leak in the hydraulic fluid which prevented the primary landing gear from deploying and the failure of the backup system. A report by the State Commission on Aircraft Accidents Investigation in Poland suggested that a popped circuit breaker may have caused the landing gear to fail. However, no alert sounded and the issue was not covered in the emergency checklist manual.
