The Biggin Hill Air Show begins tomorrow with special celebrations taking place for the airports 100th anniversary.

The Battle of Britain Memorial Flight will not be taking part in the show due to aircraft being grounded indefinitely due to engine troubles.

World War 2 era planes will be on display though as the organisers are sourcing aircraft unaffected by the safety concerns.

A spokesperson said: "A routine inspection has highlighted a fault with one of the Merlin engines in a Hurricane aircraft.

“We are currently investigating the fault and as a precaution, flying of Merlin engine powered aircraft has been paused.

“We are still operating Griffon & Gypsy powered aircraft, including Spitfires and Chipmunks.

“We realise the disappointment this will be to our many supporters, however, safety remains our paramount concern."

The organisers still expect to have their Griffon engined spitfire Mk XIX provide a display on both days but it will not be landing.
