It put a question mark over the BBMF’s expected appearance at the Scampton Airshow on September 9 and 10.

The problem has been identified as an issue with the pinion gear in a Merlin engine. 

Work can now go ahead to check each of the aircrafts’ pinion gears and whether they meet standards.

It it not known if the aircraft will be ready for the Scampton Airshow.

It is hoped the display will feature a variety of formation flypasts involving four BBMF Spitfires

An MOD spokesperson said: “Our investigation has confirmed an issue with a pinion gear in a Merlin engine.

“With the precise cause of the problem known, each pinion gear is now being inspected to confirm it meets our exacting standards, with the BBMF and industry putting all of our efforts into getting these beautiful aircraft safely back in the air as soon as possible.”

Officer Commanding BBMF Squadron Leader Andy Millikin added in a statement:

“As I hope you all know, my aim is to keep these vital and unique artefacts of Britain’s proud history in the sky forever.

“To do that we sometimes have to take extra precautions, with our eye sharply on continuing safety, to ensure that we can keep them flying for future generations.

“I thank each and every one of you who has voiced their support and shown their understanding. We will get them back into the blue as soon we can.

“Lest We Forget.”
