Ejector seat death 'once a century' event
The death of a Red Arrows pilot after the parachute on his ejection seat failed to deploy would only happen once every 115 years, a court has heard.
Flt Lt Sean Cunningham, 35, was ejected from his jet while conducting pre-flight safety checks at RAF Scampton in 2011.
The parachute on the seat did not then deploy and the airman was fatally injured, Lincoln Crown Court heard.
Martin-Baker Aircraft Ltd previously admitted to breaching safety laws.
Richard Matthews, defending, said: "The company accepts its responsibility for the significant contribution and failings it has made in the death of Lt Cunningham.
"The ethos of the company from its inception is for the ejection seat to be a lifeboat that should operate effectively in every situation."
"In the 1990s, what Martin-Baker had in place was a good system and it just failed in this instance," he said.
Mr Matthews said: "The MoD's [Ministry of Defence] assessment of the likelihood of a similar event such as this happening is that it would only happen once every 115 years."
Martin-Baker Aircraft Ltd director John Martin previously admitted on behalf of the company the failure to ensure the safety of non-employees in connection with Flt Lt Cunningham's death.
However, in a statement, the company said: "It should be noted that this was an isolated failure relating to the tightening of a nut... by RAF Aerobatic Team mechanics."
It added its ejection seats were in use by 92 air forces and had saved more than 7,000 lives.
Previously, Rex Tedd QC, for the prosecution, said: "There was a risk to many pilots over a lengthy period. The defendant's failure was anything but isolated."
Mr Tedd also told the court: "Sean's two biggest fears in life were being ejected from an aircraft, and the injuries that he would sustain, and dying at a young age. Horrifically he experienced both."
The Middlesex-based company has already agreed to pay £550,000 in prosecution costs as a result of the guilty plea.

An earlier inquest into Flt Lt Cunningham's death heard the Iraq war veteran, who grew up in Coventry, had been carrying out checks in his Hawk T1 jet when the seat fired.
It emerged during the hearing the seat-firing handle had been left in an unsafe position meaning it could accidentally activate the seat.
His parachute failed to deploy because a nut and bolt had been fastened too tightly.
Sentencing was adjourned until 23 February.
