Queens Flight helicopter accident (1950/60s ??).
Any truth in this ?
We had a Wing Commander Flying at Buckeburg around 1954 who was later promoted to Air Commodore i/c The Queens Flight. Apparently Prince Philip was to take a helicopter somewhere but took the Reserve a/c instead because something was U/S after engine start. Air Commodore J.B. took it up later to do an air test (after it was repaired ?) & was killed (? Rotor blade failure ?). Lucky Prince Philip ?.

Champagne anyone...?
Air Cdre Blount was one of 4 killed when the QF Whirlwind they were travelling in crashed in Berks, 7 Dec 67. They were on their way to Westlands to discuss buying helos for the Queens Flight. Cause was fatigue in the rotor shaft that allowed the head to separate. The fatigue was there from manufacture.
As for Prince Phillip etc - no idea!

The Duke of Edinburgh arrived at Lydd Airport-Kent this afternoon in an aircraft of The Queen's Flight from Germany.

IIRC the stories about the Duke should have been in it still sticks. The aircraft involved was planned to be in Germany for his visit but the aircaft were changed at the last moment.
Queens Flight were half life/half tolerences and the fatigue fault was caused by no more than a short interruption of the cooling fluid when the shaft was being machined.

The flaw may have been a one-off but we had a tremendous programme changing all of the Main Gearboxes on the 22 Sqdn Whirlwinds and keeping SAR operational at the same time. I was stationed at St Mawgan but found myself at Manston changing the last Gearbox when to our amazement a Victor bomber landed on a foam laid runway in our full view, the hatches were blown, possibly too late, and one landed on the port wing leading edge just where the wing profile altered. The aircraft was still there when we left.

Yes it was a machining flaw in the main rotor drive shaft. After the accident only twin engine helicopters were used by the Royal Flight. (They still had a single main rotor shaft though...)
The surviving Whirlwind HCC12 , XR 486, was transferred to 32 Squadron at Northolt. Externally you could differentiate between a HCC12 and the HCC10s by the double cabin windows on a 12. 32's HCC 10s were HAR10s modified for VIP transport by the addition of cabin linings, airline seats and red carpets. (Oh yes, and nutplates for mounting a star plate according to the rank of the occupant)
FWIW I was at Biggin Hill in April 1955 when the Queen Mum made her first trip in a helicopter to visit 600 and 2600 (City of London) Squadrons as their Honorary Air Commodore. She flew in from Smith’s Lawn, Windsor Great Park, to Biggin Hill and return in a Westland WS-55 Whirlwind of the Fleet Air Arm.
These two photos show her arrival and departure.

That would be a very long haul for a Westland Whirlwind HCC12.

Two hours and forty minutes in a Whirly is quite enough for most people and certainly too much for a Royal Personage. I'm sure HRH would have preferred an Andover.

HRH lucky to avoid accident

The stores did not have another. HRH due to fly somewhere either that day or the next, the other aircraft was not available and he was apparently not amused and had to travel by road. I received a bollocking for dropping it and was praised for not fitting it. The next time the aircraft flew was the fatal flight to Westlands with The Captain of the Queen’s Flight , the Chief Engineer, chief helicopter pilot and chief navigator.
They were all lovely people who had time of day for us fitters. It was sometime before I knew that the shaft had failed inside the gearbox so I could not have seen any crack. The experience led me to civilian career in Quality Management. The technical cause was known as “grinding abuse “. During an grinding operation at Westlands the factory experienced a intermittent power supply.
The grinding machine had three electrical motors, a big one driving the large wheel, one driving the work spindle and a small one driving the suds or coolant pump. The operator was slow in removing the cut the inertia of the big wheel carried on, but the flow of coolant stopped the work locally overheated the coolant came back on and quenched the material resulting in a local hard spot.in service this led to a fatigue crack developing.
The fleet was grounded and one outer faulty shaft was found. There is a nondestructive test for machining abuse called Nital etch inspection which if not properly carried out can result in failures from hydrogen embrittlement. At the time Westlands did not carry this out on the balance of risks, they do now. I have used this story to stop cost savings on high strength steel parts by dropping the requirements for etch inspection during my subsequent career.
