On 14 May 2010, Ryanair flight RY9ZC was scheduled from Stansted Airport (EGGS) to Alicante Airport (LEAL). During the approach phase the aircraft perform two go-around, due to meteorological conditions (windshear). The crew finally decided to divert to Valencia airport (LEVC), where they issued an urgency declaration (PAN-PAN) due to low fuel level. On final approach, the crew stated an emergency (MAYDAY) and landed successfully at runway 12.

The incident was caused by the crew’s inadequate decision-making process in opting to make a second approach, in the choice of alternate airport and in the flight parameters used en route to that airport, which resulted in the fuel amount dropping below the required minimum reserve fuel and in the crew declaring an emergency (MAYDAY).
The company’s fuel savings policy, though it complies with the minimum legal requirements, tends to minimize the amount of fuel with which its airplanes operate and leaves none for contingencies below the legal minimums. This contributed to the
amount of fuel used being improperly planned and to the amount of fuel onboard dropping below the required final fuel reserve.
Another contributing factor was the wind information provided by ATC to the crew when preparing the approach to runway 28. This information, though accurate, did not give the crew a clear picture of the changing wind conditions, which would have facilitated their making more suitable decisions.
