A Ryanair Boeing 737-800, registration EI-DAL performing flight FR-8551 from Palma Mallorca,SP (Spain) to Memmingen (Germany) with 148 passengers, was in the initial climb out of Mallorca's runway 24L when the crew received a wheel well fire indication, stopped the climb at about 5500 feet, extended the landing gear, entered a hold at 3000 feet to burn off fuel and returned to Mallorca for a safe landing on runway 24L about 30 minutes after departure. Attending emergency services found no trace of fire, heat or smoke.
A replacement Boeing 737-800 registration EI-EFL reached Memmingen with a delay of 6 hours.
The occurrence aircraft was able to resume service about 8.5 hours after landing.
The airline confirmed a wheel well fire indication, there was no fire however.
Am I right in thinking a Boeing 738 can be landed at any weight in an emergency? Palma has 3200m R/W too so wouldn't have thought it a problem.
Not sure if I would have held in the same circumstances but it wasn't my call in this case -safe outcome was the main thing.
